Frequently Asked Questions

3D printers – what they are and what they are used for

Despite the widespread use of 3D technologies, not everyone knows how 3D printers work. 3DDevice will help you understand this topic and answer frequently asked questions. Most often, users are interested in what a 3D printer is.

There are various methods of 3D printing, but their principle generally boils down to one thing. The essence of the technology lies in the gradual (layer-by-layer) reproduction of a digital 3D model in three dimensions from a specific material. These materials can vary depending on the technology used. A 3D printer is a device that creates a three-dimensional product based on digital data. In a special program, this data is converted into control code for the printer (G-code), which allows it to perform the necessary movements. This is the most accessible answer to the question “How does a 3D printer work?” Next come the details of specific techniques, which we will not go into in depth. We will only consider the most common 3D printing technologies in detail.

What does a 3D printer print with?

In the previous section, we did not fully answer the question “What does a 3D printer print with?” Below, we will give the most complete answer possible. Special materials are used to reproduce products on a 3D printer. Desktop 3D printers use 3D plastic and photopolymer resins, but it is also possible to print with rubber, flexible, and reinforced materials. More serious, professional devices allow you to print with metal and plaster, which makes them ideal for mass production. As a result, industrial 3D printers are already widely used in the aerospace and automotive industries.

What can be done on a 3D printer

So, we have figured out what a 3D printer is. Now let's talk about what you can do with a 3D printer. The most obvious answer is everything. And it is very close to the truth. Today, in addition to the familiar FDM and SLA 3D printers, there are food, industrial, 3D bioprinters, and many other variations of such devices. 3D printing is widely used for domestic purposes, and scientists have high hopes for 3D bioprinting technology, which is expected to be used to manufacture living tissues and organs. The main advantages of 3D printing over traditional manufacturing methods are high speed, simplicity, and relatively low cost.

What is 3D scanning?

3D scanning of objects

One of the components of 3D technology is the 3D scanning method, which allows you to quickly and easily obtain a digital model of the required product. In short, 3D scanning of objects is the process of converting the physical form of a real object into a digital form. The texture and even the color of the original sample are preserved. Thus, a 3D model of the required product can be obtained without unnecessary effort. 3D scanning of objects helps to prepare the required model for 3D printing and, in some cases, can play a decisive role in the construction of a digital product.

The key device in the 3D scanning process is a 3D scanner - a device that reads the physical parameters of objects and creates a 3D model based on them.

3D scanning of objects can be useful when designing any complex elements, the 3D modeling of which is extremely labor-intensive when done manually. In particular, 3D scanning is useful for modeling various fixtures, components, main parts, and spare parts. It is often used when there are no drawings or other documentation for a product, as well as when it is necessary to convert curved surfaces, including artistic forms and casts, into digital form.

The 3D scanning process

The 3D scanning process is generally similar to the human stereoscopic vision system. The process of obtaining data with a 3D scanner is similar to the formation of a three-dimensional image seen in the human brain. To do this, the 3D scanner compares two images that are offset from each other. The necessary accuracy of the 3D model is achieved through the use of additional technological techniques, such as periodic flashes or laser illumination.

As for scanning accuracy, it depends on both the specific device and the characteristics of the original product. It is possible to perform 3D scanning of objects from 1 cm (with all details), with no maximum size limit. To achieve the best detail, after the 3D scanning process is complete, the 3D model is further refined by a specialist. Thus, thanks to 3D scanning of objects, digital models are virtually flawless. The error for 3D scanning of objects with a surface area of 100 cm2 is 1 mm and can be eliminated during subsequent refinement. 3D scanning of large objects can be implemented by batch processing photos of the object from all sides.

3D scanning methods

For a better understanding of the technology, it is useful to list the existing methods of 3D scanning. There are two of them: contact and non-contact. The first requires direct contact between the 3D scanner and the object.

The non-contact method divides peripheral devices into two types:

Active 3D scanners, which emit a beam of directed waves onto the object and record their reflection. Possible types of radiation include X-rays, ultrasound, and light.
Passive 3D scanners, which record the ambient radiation reflected from the object, most often light.

All 3D scanning methods have their advantages and disadvantages, which affect the cost of 3D scanners, the speed and accuracy of scanning, and the range of objects available for scanning. When purchasing your own 3D scanner, it is recommended that you study this issue in more detail, or better yet, get quality advice from professionals. The 3DDevice team is ready to help you with this and recommend the optimal 3D scanner model.

3D scanning and 3D printing

3D scanning and 3D printing complement each other, as scanned 3D models are most often used for subsequent reproduction on a 3D printer. Currently, 3D scanning is used for a wide variety of purposes and industries. With the help of a 3D scanner, 3D models of real people are created, which can then be reproduced using full-color 3D printing with plaster. A more promising use of 3D scanning is in medicine, where it is used to create ultra-precise surgical models and implants. You can read more about our contribution to this field of medicine here. Another interesting area of application for this technology is in the production of custom footwear and clothing.

What 3D printing technologies exist?

3D printing technologies overview

We have repeatedly touched upon the topic of 3D printing technologies in various articles. The corresponding section of “Questions and Answers” even has an article with a brief overview of each method. However, we have never described the types of 3D printing in such detail as we are about to do now. We present to your attention a section with the most detailed description of each existing additive manufacturing technology!

Before we begin, we would like to say a few words about 3D printing methods in general, which will be useful to you when studying our material. So, 3D printing, also known as additive manufacturing or rapid prototyping, is used to reproduce objects based on specified 3D models. 3D models can be created manually or using a 3D scanner. However, in the latter case, the digital data also requires human processing. Now let's start talking about the different types of 3D printing.

All types of 3D printing

Below are the most common types of 3D printing used today. As new techniques are developed, we will add them to the list with detailed descriptions. Each technology name is a link to a separate page with a detailed description, examples, and types of equipment used.

Fused Deposition Modeling (FDM)
Laser Stereolithography (SLA)
Selective Laser Sintering (SLS)
Selective Laser Melting (SLM)
Direct Metal Laser Sintering (DMLS)
Selective Heat Sintering (SHS)
Laminated Object Manufacturing (LOM)
Multi Jet Modeling (MJM)
Electron-beam Melting (EBM)
Color Jet Printing (CJP)
Digital Light Processing (DLP).

What is 3D printing capable of today?

The possibilities and applications of 3D printing: what a 3D printer can do

Unfortunately, the current level of awareness of 3D technologies leaves much to be desired. Even with basic knowledge of 3D printers, the real-world applications of 3D printing remain unclear to many users. To avoid such situations, we have prepared this article and will take a detailed look at all the possibilities of 3D printing.

Applications of 3D printing

When talking about the applications of 3D printing, it is worth considering not only the existing possibilities, but also the prospects. Already today, the application of 3D printing technology is extremely broad and continues to expand. Undoubtedly, we can expect a large-scale spread of additive techniques in the future, but the practical application of 3D printing is already available to everyone today. We will not delve into narrowly specific aspects of technology, such as food 3D printing or bioprinting. Instead, we will talk about how ordinary users can apply 3D printing technology with the help of desktop 3D printers.

1. Prototyping

The best way to use 3D printing is for its intended purpose. Rapid prototyping is not only the second name of the technique, but also the original goal of its development. Creating prototypes using 3D printing significantly reduces production time and costs. And thanks to the capabilities of 3D modeling, the range of parts that can be designed is virtually unlimited. Prototyping allows you to clearly assess the possible shortcomings of a product at the design stage and make significant changes to the design of a part before its final approval.

2. Small-batch production

For small-batch production, 3D printing is a godsend. The properties of many materials allow finished components to be produced at minimal cost. Compared to traditional manufacturing methods, small-batch production using 3D printing is very cost-effective. The manufacture of casting molds, for example, is a lengthy and expensive process. At the same time, the pressure casting itself takes a considerable amount of time. With a 3D printer, however, a batch of the required products can be printed in a matter of hours. This application of 3D printing is extremely relevant for frequent orders of small batches of parts.

3. Repair and restoration

Another application of 3D printing is the repair and restoration of damaged parts. 3D printing is ideal for these purposes. This procedure can be carried out independently, if you have the appropriate skills and equipment, or at specialized 3D printing services such as 3DDevice. First, an accurate 3D model is built based on the damaged product. 3D scanning can also be used to simplify the design process. Next, the finished model is sent to print and reproduced on a 3D printer in the required number of copies. Repairing and restoring damaged parts using 3D printing is quick, and having a digital model of the component allows it to be reprinted at any time.

4. Production of functional models and finished components

One of the industrial applications of 3D printing is the production of functional models and finished components. Manufacturing products on a 3D printer from transparent material allows you to see the workings of a functional part "from the inside," which is very useful when developing various engineering samples. In addition, the wide range of materials available for 3D printing makes it a fully-fledged production tool. Industrial 3D printers are gradually becoming part of every area of production, allowing the manufacture of durable metal components.

5. Household items

Need an organizer for your office? Or a knife holder? Any household item can be printed on a 3D printer. The advantage of this application of 3D printing is that there are no restrictions when developing 3D models. This means that if you want to use your imagination and create something original, you have complete control. Thanks to 3D printing, you can decorate your home and make it more functional easily and inexpensively.

6. Toys and souvenirs

If you have a 3D printer, it is very easy to make a child happy—just make some cute 3D toys. There are already several interesting projects for collective 3D-printed games, and this list will only grow in the future. This application of 3D printing will delight not only children but also avid collectors, because a 3D printer can print figures of any characters and attributes from computer games and movies. Color 3D printing will allow you to create exclusive full-color souvenirs - miniature figures of real people. To do this, a digital model of a person is formed based on 3D scanning data. All textures and color data are preserved. Such a gift will definitely appeal to everyone, because receiving a tiny copy of yourself is so unusual.

7. Designer products

There is another application of 3D printing for creative people. 3D technology in general is a unique opportunity to express your talent in the most unusual way. Artists, sculptors, fashion designers, and designers from around the world use 3D printing to create exclusive works of art that would be impossible to produce using standard methods. Such designer products impress with their beauty and originality, often combining digital and traditional art. In addition, methods for 3D printing clothing and footwear are being actively developed. Some models are already on sale, but it is too early to talk about mass production.

8. Capabilities of a 3D printer

We have listed the main capabilities of a 3D printer, but they do not end there. 3D printing is used in a wide variety of industries. It is used to print electronics, various components, food, and even living tissue. This list will certainly grow in the future, but even now it is impressive in its scope. We hope we have been able to provide accessible information about the existing applications of 3D printing. If you have additional questions that we have not addressed, please email us and we will add your questions if necessary!

How to choose the right 3D printer?

Choosing the right 3D printer

Today, almost everyone is familiar with 3D technology. Many people are becoming interested in 3D printing and exploring the possibilities of this technology. Some are even buying their own 3D printers. If you are one of those who want to become the owner of such a device, you have probably asked yourself, “How do I choose a 3D printer?” In today's article, we will try to answer this question in as much detail as possible, provide examples, and explain what you should consider. We understand that an inexperienced user does not always know how to choose a 3D printer that will serve them for a long time and delight them with the quality of the products it produces. So let's start with the basics and list the main points that affect the performance of these devices.

First of all, you need to clearly define the purposes for which you will need a 3D printer. If you need to print miniature objects with a high degree of detail, it is better to look at SLA 3D printers. FDM devices are more versatile and suitable for a wide range of tasks. Once this question has been resolved, you should begin to thoroughly monitor the characteristics of specific devices.

How to choose the right 3D printer

To choose the right 3D printer, you should pay attention to several factors. After carefully considering all the points, the question “How to choose a 3D printer?” will no longer bother you. In this section, we will not consider SLA 3D printers, since they are somewhat simpler and their areas of application are highly specialized. Instead, we will focus on FDM printers and tell you how to make the right choice. This topic is covered in more detail in another article.

To clarify, we will explain that you do not need to meticulously study all the characteristics and nitpick every little detail. It is enough to be aware of the main parameters and consider their impact on the operation of the devices. Now let's get down to business and start choosing the best 3D printer.

How to choose a 3D printer: what to look for

1. Manufacturer

To choose a 3D printer that will meet all your expectations, you first need to identify the manufacturer of the device. This point can be divided into international characteristics:

USA. One of the major players in the 3D printing market. Many American companies have been working with this technology since its inception and offer extremely high-quality products.
Europe. Slightly weaker than the US, but also rich in reliable manufacturers of 3D printers.
China. Offers a wide variety of options, and many production facilities are also located here. With this option, you should be careful and carefully filter the offers. However, there are also very high-quality products, and a 3D printer purchased here can serve you for a very long time.
Ukraine. Our country is just beginning its journey in the 3D technology market and cannot always compete with stronger developers, especially Western ones. Nevertheless, some promising manufacturers are worth paying attention to.

2. 3D printer mechanics

One of the most important features determining the reliability of the device, smooth operation, speed, and much more is the mechanics of the 3D printer. We are referring to the actual assembly of the device and the type of guides. The latter is also responsible for working with flexible plastics. Pay attention to the type of housing the 3D printer has. An open housing is cheaper and lighter, but a closed housing allows for better control of the printing temperature.

3. Speed and accuracy of 3D printing

By and large, this parameter can be considered the most important. It is what determines the final result of 3D printing. High reproduction accuracy is one of the primary criteria for choosing a 3D printer. Accuracy refers to the layer height. At the same time, it is important to consider the accuracy/speed ratio. Don't be tempted by high speed ratings; with poor assembly, high printing speed can compromise quality. In other words, when choosing a 3D printer, look for the golden mean.

4. Build area size

As you understand, this parameter determines the possible sizes of the products you can create. The larger the working area, the larger the objects that will fit on it. Also, when printing a batch of products on a 3D printer, a large build area allows you to place more models on it at the same time. However, if you do not need to print large objects or engage in small-scale production, you do not need a large 3D printer.

5. Types of plastic

An essential parameter to focus on when buying an FDM 3D printer is the range of available materials. Basically, the types of materials are specified in the device description. But if for some reason they are not listed there, look at the extruder heating temperature and then study the melting temperature of the plastics you need. Sometimes a 3D printer is simply unable to melt certain types of materials. There can also be difficulties when working with flexible plastics, but it is best to check this with the manufacturer or distributor.

Which 3D printer is the best to buy?

Buying a 3D printer the right way

If you have reached this point, you are most likely already firmly committed to buying a 3D printer. And you understand perfectly well that buying a 3D printer must be done correctly. We have already written extensively about the criteria for choosing 3D printing devices, and in this article we will only touch on some of them superficially. Instead, we will describe in detail the requirements for 3D printers for specific purposes. We will highlight three main groups:

3D printers for home use;
3D printers for jewelers;
3D printers for dentists.

Now let's begin our specific analysis.

Which 3D printer to buy for home use

Simple tasks, household items, decorative solutions... Have you ever found yourself running around stores looking for the necessary component to repair, say, a kitchen drawer, or wanting to buy an original knife holder? Such situations are not uncommon in everyday life. To save time, money, and stress, it is better to buy a 3D printer for home use. This will greatly simplify all minor home repairs and tasks. All you need to do is create a 3D model of the required product, select the optimal type of plastic, and start 3D printing.

A home 3D printer usually does not need to have any special “bells and whistles”; it just needs to be reliable and perform the tasks at hand with high quality. Those who want to buy a 3D printer for home use should pay attention to budget models with a normal build area, support for a standard number of materials, and a reliable configuration. Such “workhorses” are suitable for many diverse tasks and delight users with high-quality 3D printing.

Which 3D printer to buy for jewelers

Jewelry 3D printing is a separate and very important branch of 3D technology. Here, more than anywhere else, the quality and accuracy of reproduction of the smallest details is important. Also, in the case of mass production of jewelry, the size of the build area is important. Therefore, when choosing which 3D printer to buy for jewelers, you should first focus on the degree of detail and the dimensions of the working area. You can also look at the type of photopolymer resins used in the printer, as they vary.

Reinforced, heat-resistant, and other materials are available, suitable for a wide variety of tasks. If you are considering purchasing an SLA 3D printer for home use, it is best to weigh your options carefully, as this type of 3D printing is not suitable for every task.

Which 3D printer to buy for dentists

When deciding which 3D printer to buy for dentists, oddly enough, you will have to pay attention to the same SLA 3D printing. Its advantages are just as good for dentists. By the way, representatives of both professions would do well to pay attention to a variation of stereolithography printing known as DLP 3D printing. The principle of its operation is roughly the same, but instead of a laser, a projector is used. As a result, objects are reproduced much faster using this method. This is also an important criterion when choosing a 3D printer.

If you have any additional questions that we have not addressed, please email us and we will add your questions if necessary! Sincerely, the 3DDevice team. Please contact us, we look forward to working with you!

Which plastic is best to use?

Which plastic is best for 3D printing?

After purchasing your own FDM 3D printer, and also during the selection process, you will need to choose the right plastic for 3D printing. But how can you do this if you are new to 3D printing and know little about it? In most cases, the plastic used for 3D printing is the main component for successful reproduction of products. Therefore, we will not skimp on knowledge and will tell you how to choose the best plastic for 3D printing.

Types of plastic for 3D printers

First, you need to consider the types of plastic for 3D printers. Plastic for 3D printing, or filament, is produced in the form of a thin thread with a diameter of 1.75 mm and 3 mm. Most often, 1.75 mm thick threads are used in the basic configuration, but some 3D printer manufacturers offer the option of installing a 3 mm plastic feed system. There are many types of plastic for 3D printing, the most common of which are ABS and PLA plastic.

Plastics for 3D printing: types

Based on popularity in the Ukrainian market, the following types of plastics for 3D printing can be distinguished:

PLA (polylactide). Organic and short-lived. Suitable for 3D printing of decorative items, but unable to withstand heavy mechanical loads;
ABS (ABS) or acrylonitrile butadiene styrene. Has a long service life and excellent mechanical properties. Heat-resistant and used for industrial purposes. Shrinks when cooling. It is recommended to print in ventilated rooms;
PVA (polyvinyl alcohol). A water-soluble material used as a support;
Nylon. An alternative to ABS plastic, suitable for many engineering structures. When printing with nylon, it is recommended to ventilate the room;
HIPS (High Impact Polystyrene). In terms of physical properties, it is somewhere between PLA and ABS. Printing with HIPS can also produce toxic fumes.

Which filament is best for a 3D printer?

In fact, there are many more types of plastic for 3D printing. These include flexible, fluorescent, and luminescent filaments, as well as wood and metallized materials. However, in practice, such consumables are rarely used and are needed for very specific purposes. Metallized plastics are interesting in themselves, but they are in the early stages of development and are inferior in performance to ordinary reinforced materials. “So which plastic is best for a 3D printer?” you may ask. The choice should be based on specific goals. If you intend to print decorative elements that will not be subjected to useful loads, you can consider PLA plastic. If your goal is to print gears, structural parts, and other items, consider reinforced materials for 3D printing.

What plastic should you print with?

Please note that not every printer supports the entire range of materials for 3D printing. Before purchasing a specific filament, check the specifications of your device to avoid wasting money. The rest is up to you and your imagination. A huge range of colors and shades of plastic are available, including matte and glossy, semi-transparent and completely transparent materials. This variety allows you to create virtually any product to your liking.

Remember, if you need to buy plastic for 3D printing, the 3DDevice store is at your service! We offer a wide range of different materials in all possible colors and are ready to advise you on choosing a filament. We look forward to working with you!

What software should be used for 3D printing?

How to operate a 3D printer? Programs for 3D printing

In order to get started with 3D technology and learn how to operate a 3D printer, you need to master certain programs for 3D printing. These include specialized software and applications for 3D modeling. In today's article, we will look at all categories and determine which 3D printing programs are best to use. So, what you will need:

Programs for 3D modeling. Here, 3D models are designed, which will later be reproduced on a 3D printer;
Programs for correcting errors in digital models;
Slicer programs. They convert 3D models into control code for a 3D printer.

Now let's move on to describing each category and provide a short list of the most commonly used applications.

Programs for 3D modeling

Programs for 3D printing can be divided into several branches, one of which is programs for 3D modeling. They are indispensable for the work, because it is here that three-dimensional digital figures of the required products are created. There are two ways to build a 3D model: using a 3D scanner or manually. Here is a list of popular software for developing and editing digital models:

Autodesk 3Ds Max. One of the most popular and functional 3D editors. Suitable for creating any objects, but it is better not to design organic elements in this program. A favorite tool of designers from all over the world, 3Ds Max is difficult to learn, but attracts users with its free license. On the plus side, there are a large number of tutorials available online. On the downside, the program is not suitable for preparing for 3D printing; it is better to refine the created 3D models in other software.
Blender. A program that is gradually gaining well-deserved popularity. It is multifunctional, convenient, and easy to use.
SolidWorks. A program for solid 3D modeling. Objects created in it are ideal for 3D printing. In addition, it allows you to create detailed and comprehensive volumetric drawings, making it the optimal choice for engineers. Training materials for SolidWorks are also easy to find on the Internet.
Autodesk 123D Design. Another product from Autodesk. The program is very functional and has a pleasant interface. It can rightly be called the best 3D editor for beginners. It is simple and easy to learn. The only drawback is the lack of training lessons and Russian-language forums.

Programs for 3D printers

Now let's list the programs for 3D printers. This includes slicer programs and editors for damaged models. Such programs for 3D printing allow you to prepare a 3D model that is too large or damaged for reproduction, and then generate control code for the 3D printer. If the model is too large, it can be “cut” into several parts in Autodesk 123D Make. After actual reproduction on a 3D printer, they are joined together. Autodesk's NetFabb product also comes in handy when you need to edit a damaged 3D model. To do this, you just need to load it into the application and select the repair mode.

Programs for working with a 3D printer

Programs for working with a 3D printer are slicer software, which is necessary to convert a 3D model into g-code for the printer. Here, an algorithm is generated that allows the device to understand how to behave during printing. There are different versions with different, but generally similar, functionality. Here is a list of such programs for 3D printing:

A universal, free, and functional slicer program. It offers a large number of options and fast performance.
Available in both paid and free versions. Also a very popular and functional slicer. Known for its well-designed menu for generating support structures.
A simple and convenient program, especially appealing to beginners in 3D printing. It is worth noting that it is free and the software is constantly being optimized;
Makerbot desktop. Accompanies equipment from the company of the same name. A decent and functional slicer, whose disadvantage is the lack of flexibility in settings. This is understandable, as the program is designed specifically for native 3D printers.

These are the main programs for 3D printing that will be useful to you at all stages of working with a 3D printer. If you have additional questions that we have not covered, please email us and we will add your questions if necessary!

What is the cost of manufacturing a product?

3D printing price and profitability

Surely every novice user of a 3D printer, or anyone wishing to purchase one, is interested in the question “What is the real cost of 3D printing?” This is important not only for those who want to build their business, but also for private users who calculate material consumption. No one needs 3D printing that costs more than the likely income from it. Often, this interest arises even before the decision to purchase a 3D printer and accompanies it until the first samples are reproduced. But you can calculate the approximate plastic consumption yourself long before purchasing a printing device. This way, you can avoid 3D printing prices that may unpleasantly surprise you.

The cost of printing on a 3D printer

The cost of printing on a 3D printer is easy to calculate using slicer software. All you need is a 3D model of the object in STL format. Most often, such programs are free. They are often released specifically for specific hardware, but are free and available for download from the Internet. For example, the Cura program allows you to accurately calculate the printing time and material consumption. But first, you will need to set the basic parameters: plastic type, nozzle diameter, etc. After loading the model into the software and setting the necessary values, the program will calculate and display the necessary information about the printing process. This way, you will know the approximate amount of plastic required to manufacture a single product. The data obtained can be easily compared with the price of materials by analyzing average market prices.

The price of 3D printing

As you can see, the price of 3D printing is fairly easy to determine. You can calculate the cost of 3D printing for a wide variety of materials, thus assessing the profitability of using a 3D printer. Don't forget that you can print with different types of plastic, but they are mainly sold in spools of at least one kilogram. Keep this in mind so you don't end up with a huge amount of unnecessary material on your hands. We can note that plastic consumption is not high at all, but you must not forget about support material and filling. If you want to produce high-quality samples, you will have to slightly increase consumption. But this is not critical, we can assure you.

What myths and misconceptions exist?

Myths and misconceptions about 3D printers and 3D printing

As we know, things that people don't understand very well tend to become shrouded in myths and misconceptions over time. 3D printing technology is no exception. Unfortunately, in Ukraine, awareness of 3D technologies is extremely low, which does not help the perception of innovative methods. There are many different myths about 3D printing, based on what people have already heard about the technology. Printing on a 3D printer is a very unusual process. But most people do not bother to gain a deeper understanding and are satisfied with superficial explanations of how the technology works. This is how myths about 3D printing arise.

In this article, we will try to list the most common myths about 3D printing and dispel them with well-reasoned facts. We hope this section will help you learn more about 3D technologies and better understand the process of printing with a 3D printer.

The most common myths about 3D printing

Let's start this section by listing the most common myths and misconceptions about 3D printing. So, here's what people often think about printing with a 3D printer:

1. It's expensive

The myth about 3D printing is proudly led by the opinion about its cost, and this is no coincidence. People are convinced that 3D printing is very expensive and inaccessible to the average user. This myth is only half true. Prices for industrial 3D printing equipment are indeed very high. But that's because it's professional equipment used in manufacturing. The cost of desktop 3D printers is much lower and continues to fall as the technology develops. Prices for consumables are also falling. This already makes 3D printing very affordable, and in the future, 3D printers will become a part of almost every home.

2. It's professional

Many people believe that 3D printing is only suitable for a narrow range of specialized tasks or industrial applications. We can assure you that this is not the case. Of course, the prospects for 3D printing in industry are extremely promising, but a 3D printer can be just as useful for home use.

3. You can only print with plastic

This is a completely absurd opinion. 3D printing technology is steadily moving towards the point where any material can be used. Today, there are already food 3D printers, 3D bioprinters that print with living cells, and devices that print with metal, wood, silicone, rubber, clay, and even glass. Contour construction, or 3D printing of houses, is also actively developing. As you can see, you can print anything, with almost anything.

4. 3D printing is only suitable for creating trinkets

Contrary to the opinion about the professional use of 3D printers, there are thoughts that 3D printing is unsuitable for creating serious things. Various functional models and final parts manufactured on 3D printers will help to convince skeptics. Many large aerospace and automotive companies use 3D printing in their practices. For example, Airbus has launched a factory that uses exclusively additive manufacturing techniques. And the creation of cars using 3D printers has already become a very common practice.

Myths about 3D printers

Having listed the common myths about 3D printing, let's move on to the myths about 3D printers. Some exaggerate the capabilities of these devices, while others underestimate them. But myths about 3D printers exist, and it is our job to dispel or confirm them. So, what do ordinary people think about 3D printers?

1. It is a complex device

On the one hand, you can't argue with that. The device is indeed complex, but developers are working to make 3D printers as easy to use as possible. Desktop devices are designed for comfortable and simple operation. For example, Kickstarter featured a project for the simplest 3D printer. Moreover, you can assemble some printer models yourself. And if you do everything right, they will work quite well. So it's not as complicated as it seems.

2. Products do not require post-processing

This is perhaps the biggest misconception. As much as we would like it to be, you can't just print something and be done with it. Objects must undergo a minimal post-processing process, especially if they were printed with supports.

3. You can print in any color

Unfortunately, modern desktop 3D printers are not yet capable of printing full-color samples. There are models with multiple extruders, but the maximum possible is two or three colors. On industrial printers, however, it is quite possible to print products in full color. Nevertheless, developers are actively working to eliminate this limitation and are making significant progress. Relatively compact printers for full-color printing already exist. All that remains is to wait for them to hit the market en masse and for prices to fall.

How much does a 3D printer cost?

The real cost of a 3D printer

Now that you know all the ins and outs of 3D printing, the different types of technologies and devices, it's time to answer the question, “How much does a 3D printer cost?” In this section, we will give you the answer and explain what determines the price of a 3D printer.

Types of 3D printers

As you already know from our previous articles, additive manufacturing techniques vary greatly. Not only does the reproduction process itself differ, but so do the working materials. Among the most common technologies are:

FDM printers, which print with filaments of various polymer materials;
SLA 3D printers, which use a special liquid photopolymer resin as a consumable;
SLS 3D printers, which use metal, gypsum, or plastic powder.

Of course, such a huge difference in model production methods cannot but affect the cost of 3D printing devices. In each of the categories presented, there is a division into budget and professional devices, but all SLS 3D printers are a step above devices of other classes. There are a number of reasons for this, which our article on 3D printing technologies will help you understand. After all, in order to determine how much a 3D printer costs, you need to understand the specifics of the techniques. In terms of cost, printers can be ranked in the same order as they are presented above. Let's explain why.

Application of 3D printers

When determining the cost of a 3D printer, it is essential to consider its type and intended application. Depending on the 3D printing technology, the device can be tailored to specific tasks. For example:

SLA 3D printers are optimal for jewelry and dental applications, as well as for creating miniature detailed products. Although more serious, professional models of such printers are used for the production of larger objects. The price corresponds to the quality, but remains quite high due to the specifics of the technology;
FDM 3D printers are the least expensive and come in a wide variety of models. They are the most affordable option for home use, while more professional models are suitable for the needs of a small business;
SLS printers are the most professional option for industrial use in a variety of fields. Thanks to their ability to print with metal, they are used in the aerospace, automotive, medical industries, etc. For the most part, these are large installations weighing several tons, not suitable for home use. These are the most expensive 3D printers available.

How much does a 3D printer cost?

Otherwise, the price of a 3D printer depends on the accuracy of 3D printing, the size of the build area, the reliability of the device and the quality of the components, as well as the brand. Yes, the manufacturer is just as important in the field of 3D printing as in all other areas. And often, users have to pay a lot of money for the brand. On the other hand, they are also paying for the quality of the product, which they do not want to risk.

So, we have looked at the main types of 3D printing devices and identified the factors that determine their price. It's time to answer the question of how much a 3D printer costs. The price of industrial metal printing devices can reach hundreds of thousands of euros, making them a more acceptable option for large enterprises. Traditional SLA and FDM 3D printers cost much less and are available to the average user. To find out the real prices of 3D printers, visit our online store, which offers the latest models of high-quality 3D printing devices. You will also find various 3D scanners, spare parts, and accessories for 3D printing, as well as a wide range of consumables (plastics and resins).

What is 3D printing?

3D printing – what it is and how it can be used

3D printing technology was patented in the 1980s, but it has only recently gained popularity. New, promising methods have been developed, and the possibilities of 3D technology have reached a whole new level. However, even today, the method is not known in all circles, and not everyone is aware of what 3D printing is. In today's article, we will try to explain in detail and in an accessible way what 3D printing is and where it is used.

In short, 3D printing is a method of manufacturing three-dimensional products based on digital models. Regardless of the specific technology, the essence of the process is the gradual layer-by-layer reproduction of objects. This process uses a special device - a 3D printer - that prints with certain types of materials. More details about it can be found here. Other names for this technology are rapid prototyping or additive manufacturing. The term “additive technologies” is often used to mean “3D technologies.”

Stages of 3D printing

To help you understand what 3D printing is, let's look at the reproduction process step by step. Below are the specific stages of 3D printing. How it works:

3D modeling of the required object is performed according to certain rules;
The file with the digital model is loaded into a slicer program, which generates the control code for the 3D printer;
The necessary 3D printing parameters are set;
The code is written to a removable storage device, which is connected to the 3D printer;
The 3D model is reproduced.

Objects are reproduced gradually. The selected material is applied layer by layer in the required shape, forming the finished product. It is worth noting that the possibilities of 3D printing are virtually limitless, meaning that anything can be manufactured. In some technologies, supports are provided for very thin overhanging elements to prevent them from sagging.

Of course, this is a very simplified description of the stages of 3D printing, but it gives a fairly clear idea of the essence of the technique.

3D printing technologies

Various 3D printing technologies are used to reproduce different objects. They differ in terms of the consumables used, as well as the speed and accuracy of printing.

Let's list the main 3D printing technologies:

Fused deposition modeling (FDM). One of the most common 3D printing technologies, used in most desktop 3D printers and offering an ideal price/quality ratio. Printing is done by layering melted plastic filament.
Laser stereolithography (SLA). The object is formed by layer-by-layer exposure of liquid photopolymer resin to a laser, which hardens under the influence of radiation. One variation of this technology is DLP 3D printing. Instead of a laser, it uses a special projector. Both 3D printing methods are used to create objects with a high degree of detail. In the case of DLP printing, speed is also an additional advantage;
Selective laser sintering (SLS). Reproduction is performed by layer-by-layer melting of a special powder under the action of laser radiation. This 3D printing method is widely used in industry for the manufacture of durable metal elements.

Application of 3D printing

The application of 3D printing is extremely broad. The second name of the technology—rapid prototyping—speaks for itself. 3D printing can be simply indispensable in the manufacture of prototypes and model layouts. It is also a very cost-effective solution for small-batch production. In the aerospace and automotive industries, 3D technologies are already widely used due to their high cost-effectiveness and speed of component manufacturing. Chefs are working on the development of food 3D printers, and in medicine, 3D printing has become something of a technology of the future. With the help of 3D bioprinting, it is planned to produce bones, organs, and living tissues, but for now, 3D printers are used to print implants and full-fledged medicines. Desktop 3D printers can be used for domestic purposes: for repairs, manufacturing various household items, and so on. Designers, fashion designers, sculptors, and artists highly value the possibilities of 3D printing and 3D modeling as an unusual way to realize their talent.

What is a 3D model?

3D model – what it is

One of the basic points in studying 3D technologies is a complete understanding of the 3D modeling process. This is the cornerstone of all three-dimensional techniques, and the first thing to do is to explain what a 3D model is.

A 3D model is a three-dimensional digital image of a real or fictional object. 3D models are created using special 3D modeling software. The functionality of such programs may vary slightly. For example, there are programs focused on designing engineering 3D models, software specifically for modeling organic objects, and applications for 3D visualization and animation. In reality, there is no strict classification of software, but most applications contain certain functions aimed at performing specific tasks.

What is 3D modeling

When explaining what a 3D model is, it is necessary to briefly explain what 3D modeling is.

3D modeling is the process of creating a three-dimensional digital image of the desired object. Depending on the specific goals, the requirements for 3D modeling may vary. That is, in the development of computer games, certain laws of constructing 3D models are applied, which may not be useful when creating 3D models for 3D printing. For more details on the rules of 3D modeling for 3D printing, read this article.

The surface of a 3D model is a set of geometric shapes—triangles or rectangles—which together form the desired object. If desired, you can learn how to create a 3D model on your own, but in case of urgent need, it is better to turn to professionals.

Application of 3D modeling

There are many areas of application for 3D modeling, the main ones of which are worth mentioning. You can develop a 3D model for anything. 3D modeling is widely used:

In the development of computer games;
As one of the stages of 3D visualization;
For preliminary assessment of the technical properties of the designed product;
In preparing samples for 3D printing;
For creating product prototypes.

Recently, 3D modeling has become an essential stage in the production process, as it allows for a detailed assessment of the designed samples. In the future, such a 3D model will be useful for manufacturing prototypes and models of the products being created.

What is RepRap technology?

The RepRap Project

When learning about 3D technologies, users often encounter the term “RepRap.” In this section, we will explain what RepRap technology is and what its advantages are.

The RepRap project began in 2005, when 3D printing was just starting to gain momentum. Its founder is Dr. Adrian Bowyer, a professor of mechanical engineering at the University of Bath in the UK. The goal of the RepRap project is to enable people to set up their own production system at minimal cost.

Initially, the RepRap project was open source, and all source materials were available for download on the Internet. The project was run through the founder's blog, and anyone could download the drawings and diagrams they were interested in. In fact, accessibility is one of the main advantages of the project.

RepRap 3D printer

RepRap technology stands for Replicating Rapid Prototyper. Literally translated, it means “(self-)replicating rapid prototyping mechanism.” It is precisely the ability to independently reproduce its own parts that makes the RepRap 3D printer so interesting. With the purchase of such a printer, users get the opportunity not only to fully print in 3D with a variety of materials, but also, if necessary, to manufacture a similar “daughter” device.

This useful feature of the 3D printer significantly reduces its cost. Thanks to this, the user has the opportunity to produce fairly complex products without having to organize expensive production infrastructure. Thus, this technology allows anyone to create the necessary objects without significant costs and effort. The only expense will be the plastic for 3D printing.

RepRap technology

Since its inception, RepRap technology has received a lot of positive feedback. RepRap 3D printers have earned a reputation as the simplest and most affordable 3D printing devices on the planet. Even more public attention was attracted by the news that 3D printers of this class are now capable of reproducing electrical circuits.

This is a new step in the development of non-self-replicating devices.

What are the prospects for 3D printing in the future?

The future of 3D printing

The future of 3D printing is already looking super promising. Scientists are actively developing existing 3D printing techniques, coming up with new technologies and materials, and finding new ways to use it. Many call 3D printing the technology of the future, and there are reasons for this. The technique has the potential to completely transform our way of life by changing the way most things are manufactured. In essence, a 3D printer is a true multifunctional factory, small and compact. Because of this, the future of 3D printing can definitely be called successful.

3D printers can significantly reduce production costs, which will also reduce the cost of products. Judging by the growing trend towards the popularization of 3D technologies, raw materials for 3D printing will become the main commodity in the future. In general, the prospects for 3D printing are clear for many areas. And now we will try to reveal them as much as possible.

The future of 3D printing

If we try to imagine the future of 3D printing, our imagination paints a rather interesting picture. Given the great interest of scientists in the 3D bioprinting technique, which is one of the most promising 3D printing technologies, the manufacture of artificial organs on a 3D printer is just around the corner. We can also say with confidence that the future of 3D printing will bring us radical changes in areas such as:

Construction. 3D printing of houses, or contour construction, attracts many with its futuristic nature and simplicity. The first steps in this direction have already been taken. The Chinese were the pioneers in 3D printing of houses, followed by the Dubai government, which discovered contour construction. The first 3D-printed office building has already been built in this city of the future, and there are plans to print an entire neighborhood in the near future. And just recently, the first printed house in Europe was created on a 3D printer.
Electronics. When listing the prospects for 3D printing, this point deserves special attention. Scientists consider 3D printing of electronics to be the future of digital device manufacturing, and not without reason. Currently, active research is being conducted on the properties of graphene and its application in additive manufacturing. A huge breakthrough in this area is the creation of a graphene battery with an unlimited service life using a 3D printer.
Automotive and aerospace industries. The future of 3D printing is largely based on its ability to reproduce virtually any element of varying complexity. In this regard, 3D printing is already widely used in the development of aircraft, cars, and satellites. The ISS even has its own 3D printer, not to mention a number of successful results in 3D printing of cars.
Pharmaceutical industry. Yes, you can imagine it. The future of 3D printing lies in the manufacture of tablets and other medicines. This is confirmed by the legalization in the US of epilepsy tablets manufactured using a special method. The essence of this prospect for 3D printing lies in the gradual release of active substances, thanks to which it will be possible to take just one tablet instead of many.
Food industry. 3D printers for printing food are gradually gaining ground in cafes and restaurants. Although this is probably one of the rawest 3D printing technologies, it has great potential. Food 3D printers are particularly interesting for their ability to produce food for astronauts, as well as for the freedom they offer to express culinary talent. This is confirmed by the amazing 3D-printed desserts created by our compatriot.

The future of 3D printers

Now let's try to imagine the future of 3D printers. There are several important points to consider here. Below we list the most likely scenarios for the future of 3D printers.

Improved reliability and quality of devices. Surely, many users are eagerly awaiting this, because most existing 3D printer models cannot boast of uninterrupted operation and the absence of errors when printing.
Widespread distribution. It is quite certain that the future of 3D printers will delight us with their popularization. Even now, we can observe a growing trend toward the use of 3D printing in virtually all areas of industry. As more and more users learn about the capabilities of the technology, the demand for desktop 3D printers is also growing.
Accessibility. Following on from the previous point, it is worth noting that growing demand for 3D printers will lead to a reduction in the price of these devices. The use of 3D printing for domestic purposes is gaining momentum, bringing new equipment manufacturers to the market. Naturally, this will lead to a reduction in the price of devices.
Increased build area. 3D printing of large objects has long been on the minds of developers. Of course, this applies to industrial 3D printers, because the functionality of 3D printing on such a scale will allow the creation of full-fledged components, for example, for cars and airplanes.
Expansion of the range of available materials. The future of 3D printers largely depends on the materials used for 3D printing, because more materials mean more possibilities. Many companies are developing special equipment and corresponding materials, and there is constant news about the release of new polymers.

3D technologies of the future

To sum up, we only need to look at the 3D technologies of the future. These include various futuristic scenarios that are already beginning to develop to some extent today. These include virtual reality techniques, 3D scanning to create the perfect clothes and shoes, 3D-printed makeup, and more. In a way, 3D technologies of the future also include bioprinting. By the way, scientists are talking about building the first 3D-printed settlement on the Moon and Mars, so the prospects for 3D printing are also relevant beyond Earth.

This was a list of the main scenarios for the future of 3D printing. Let's see how much of it comes true. If you have additional questions that we have not covered, please email us and we will add your questions if necessary! Sincerely, the 3DDevice team.

Which 3D printer manufacturers are the best?

3D printer manufacturers: what to look for

If you are interested in 3D printing and intend to buy your own 3D printer, you are probably interested in which 3D printer manufacturers exist. In this article, we will try to answer this question in as much detail as possible and list the existing manufacturers.

Of course, it makes no sense to talk about all developers, because there are so many of them. Today, 3D printer manufacturers are divided not only by the type of technology their devices use, but also by the class of devices.

In general, all 3D printer manufacturers can be divided into three groups:

Professionals. They produce the highest quality equipment, including industrial equipment. The cost of their products is, accordingly, significantly higher than average market prices, but the buyer pays not only for the brand, but also for reliability.
Mid-range. The vast majority of 3D printer manufacturers fall into this category. These are companies that have already established themselves in the market but have not yet reached a certain point. They produce products of decent quality at a very affordable price.
Start-up manufacturers. These are mainly young, enthusiastic developers who are eager to bring their product to market. It is possible that their products may be of decent quality, but often such 3D printers are very crude and unfinished.

High-quality 3D printer

Of course, if you want to buy your own 3D printing device, you want to purchase the highest quality 3D printer possible. But what if all 3D printer manufacturers praise their products? How do you decide? Let's figure it out.

First, you should only trust proven equipment developers. See which 3D printer manufacturers have been on the market for a long time and what they offer.

Second, analyze the options available. Compare the prices and specifications of 3D printers and read reviews. Another good option is to seek professional advice from distributors. For example, 3DDevice will always help you make the right choice.

Popular 3D printers

To clarify things and help you make your choice, it is worth mentioning the most popular 3D printers. Well-known manufacturers of 3D printers, such as Stratasys, 3D Systems, MakerBot, Formlabs, CreatBot, and Ultimaker offer good options, and the market is flooded with their products. The advantage of choosing a popular 3D printer is its ease of use. After all, you are sure to find a tutorial video or review of the model you need online.

Of course, when choosing a 3D printer, you should not focus solely on the manufacturer. There are many selection criteria to consider. Nevertheless, 3D printer manufacturers are not the last factor to pay attention to.

If you have additional questions that we have not addressed, please email us and we will add your questions if necessary!

Where to buy a 3D printer?

Where to buy a 3D printer: considering the options

If you have carefully read the previous sections, you probably know what to look for when buying a 3D printer. But if you want to purchase your own device, the information you have may not be enough. The next logical step is to ask, “Where can I buy a 3D printer?” Of course, everyone wants to get the highest quality and most reliable device possible.

That's why in this section we'll help you figure out where to buy a 3D printer to avoid potential problems and achieve high-quality 3D printing.

Where can you buy a 3D printer?

A 3D printer is not a very affordable or common item; you can't just go to your local supermarket to buy one. And in Ukraine, unfortunately, there are not many places that sell 3D printers. Obviously, this causes certain difficulties for those who want to purchase equipment for 3D printing. This raises the question: where can you buy a 3D printer? Let's figure it out together. Below, we will list the possible options and consider the advantages and disadvantages of each.

Buying a 3D printer abroad

The first option to consider is buying a 3D printer abroad from the official manufacturer. This option is interesting because the 3D printer is purchased directly from the developer without the markup from distributors and suppliers. At the same time, there is less chance of receiving a used or low-quality product. However, purchasing a 3D printer abroad entails a lot of additional shipping costs. Thus, you will not save much money. So, when choosing where to buy a 3D printer, it is better to postpone this option.

Buying a 3D printer in China

One variation on the previous point is buying a 3D printer in China. This option is interesting due to the variety of choices available, but it is more risky than buying a 3D printer abroad. In addition to long delivery times, there is a chance of receiving damaged equipment and used goods. Of course, no one is immune to this, but it is Chinese suppliers in particular who often have problems with equipment delivery. Also, don't forget about warranty service and the need to maintain contact with the seller. Therefore, if you are looking for where to buy a 3D printer, think twice before settling on this option.

Where to buy a 3D printer in Ukraine?

Of course, to avoid many problems and simplify the task, it is better not to buy equipment outside Ukraine, or even outside your city. As mentioned above, this is not always possible. But the situation is not hopeless. So where to buy a 3D printer in Ukraine? Of course, we recommend the 3DDevice store. It offers a wide range of 3D printers and other equipment, so you can easily choose the device you need. Our staff is ready to consult with you and select the optimal 3D printer specifically for your purposes. In addition, we provide mandatory warranty service and, if necessary, training on how to use a 3D printer. And the best news is that we operate throughout Ukraine!

We hope that after such a detailed explanation, the question “Where to buy a 3D printer?” will no longer bother you. If you have additional questions that we have not addressed, please email us and we will add your questions if necessary! Sincerely, the 3DDevice team.

We would also like to remind you that we provide FDM and SLA 3D printing, 3D scanning, and 3D modeling services if needed.

What additional materials are needed?

Additional materials for 3D printing

If you are the proud owner of a 3D printer, congratulations! We are publishing this article for you, as well as for those who are just planning to purchase their own 3D printing device. After all, plastic alone is not enough to work with a 3D printer. You will need a number of additional tools, spare parts, and accessories. All of them are designed to simplify your work, facilitate post-processing of parts, and minimize possible errors in the operation of the 3D printer. In this section, we will tell you exactly what materials you will need for 3D printing. We recommend that you read the information very carefully and take our advice into account.

Accessories for a 3D printer

Perhaps this name is a little strange, but it is the accessories for a 3D printer that play a huge role in the entire 3D printing process. These include:

Blue tape or Kapton tape. One of the most important elements in the system. They protect the work platform from damage, extend its service life, and make it easier for products to stick to the platform.
Special glue to improve adhesion. This material is used when the platform does not have a heating function. Otherwise, it can be used as desired.
Thermostatic device. This is a special device that increases heat dissipation efficiency. It has the shape of a dome, inside which a 3D printer is placed. This material can be used for high-quality 3D printing with ABS plastic;
SD memory card with a capacity of up to 2GB. This is an essential accessory, without which the 3D printer will not print. The control code for the printer is recorded on it. The file system of the storage device is FAT. It is recommended not to print 3D directly from a computer;
Paper clips. Some manufacturers recommend installing a glass surface on top of the standard heating platform. This ensures the uniformity of the working platform and also makes it easier to replace the surface if necessary. The glass surface is attached to the working platform using ordinary paper clips.

Materials for a 3D printer

These include both specialized devices and tools, as well as items that can be found in every home. So, what materials are needed for a 3D printer?

A sheet of A7 paper for calibrating the 3D printer bed. For more details on this process, see here;
Mini spatula. This material will come in handy when separating the finished object from the platform;
Wire cutters and a Dremel tool. Indispensable for removing support material and post-processing products;
Acetone or a special liquid for polishing plastic products. This material is used when working with ABS plastic and materials that are sensitive to acetone vapors. Polishing with acetone allows you to achieve a perfectly smooth, glossy surface on products that is difficult to distinguish from an industrial sample. In addition, acetone helps to glue several parts together or remove cracks in the plastic;
Open-end wrenches and hex keys.

Spare parts for 3D printers

In addition to materials and accessories, spare parts and accessories for 3D printers are an important point that cannot be ignored. Of course, we wish you successful 3D printing and hope that there will be no interruptions in the operation of the device. But in any case, it is useful to be aware of all the possibilities and, when necessary, be able to select the optimal materials for 3D printing. So, here is a list of essential accessories for a 3D printer:

Needle for cleaning the nozzle. Unfortunately, nozzles sometimes get clogged. In this case, it is important to have a “first aid kit” – a special needle of the appropriate diameter;
Spare nozzles. If you cannot save the nozzle with a needle, you will need to replace it. In this case, it is better to have several spare nozzles on hand. For better layer height control, it is recommended to install nozzles of different diameters;
Additional cooling fan. This part is not of primary importance, as it is often already included in the basic configuration of a 3D printer. If the fan is missing or has failed, it will need to be replaced or installed. It is necessary for the timely cooling of the applied layers, which will improve the print quality.
In fact, the listed materials for 3D printing are only our recommendation. You can do without some of them, and you can replace others. During the printing process, you will understand what you need and what you can do without. We would like to remind you that all accessories, spare parts, and additional materials are available in our store. If you have additional questions that we have not addressed, please email us and we will add your questions if necessary!

What should I do if problems arise?

3D printing: problems and solutions

Of course, all beginners in 3D printing want to avoid potential problems as much as possible. But this is the most difficult stage. The culprits can be incorrect print settings or hardware malfunctions. Lack of practical experience with a 3D printer also plays a role.

In addition, a 3D printer is a rather capricious machine, and you often have to find your own approach to it. As you can see, there are many possible causes of difficulties. And so that the problems that arise during 3D printing do not leave you at a dead end, we have compiled this section. In it, we will try to list the most common problems in 3D printing and effective ways to solve them.

Problems when printing on a 3D printer

Problems when printing on a 3D printer can arise for anyone, no one is immune to this. Therefore, it is important to know about the typical difficulties in 3D printing and be able to solve them. Users can solve almost all problems with 3D printing on their own without any particular difficulty. Only in the case of physical damage is it advisable to contact a special service center without trying to fix the problem yourself. But below we will look at common problems with 3D printing that absolutely any user may encounter.

Problems with 3D printers

FDM 3D printing has certain characteristics. Problems with 3D printers are often caused by these characteristics, and they should be solved with this in mind. Let's not delay any longer and get down to business.

1. Insufficient adhesion (the model does not adhere well to the 3D printer table)

To build a high-quality object, it is extremely important to ensure that the plastic adheres well to the work platform. Otherwise, the sample is unlikely to print properly. Possible causes of insufficient adhesion:

Large gap between the nozzle and the 3D printer bed;
The working platform is not calibrated;
The printing speed of the first layer is too high;
Incorrect temperature or cooling settings.

How to solve it: If the problem is with the 3D printing settings, change them according to the requirements for the specific plastic. Be sure to calibrate the 3D printer platform according to all the rules. This is a very important step in the printing process. It is also possible to apply special materials to the platform for better adhesion: Kapton, blue tape, or special glue.

2. Under-extrusion or over-extrusion

These terms refer to insufficient or excessive plastic feed, which leads to poor-quality prints. Although these problems are diametrically opposed, they have the same root cause. Reasons:

Incorrect plastic filament diameter setting;
Incorrect extrusion ratio;
Mechanical problems.

How to solve: Set the optimal 3D printing settings or check the plastic feed unit and pressure mechanism.

3. Overheating during 3D printing

During the 3D printing process, plastic is fed at a very high temperature onto an equally hot platform. If the cooling parameters are set incorrectly, the model will overheat, leading to deformation.

The main causes of this problem are high printing speed and insufficient cooling. The solution is to determine the optimal parameters for a specific material. After all, the melting and cooling temperatures differ for different plastics.

4. Thin plastic webs on the model

This is a common phenomenon that is quite difficult to get rid of. Small plastic webs in several places on the object are normal. But if there are too many of them, it is worth digging into the 3D printing settings. Most often, the correct setting of the plastic retraction parameter helps to get rid of such threads. Check the values of the distance and retraction speed. Basically, after a few trials and errors, you will understand how to set this parameter correctly. Also pay attention to the temperature regime. Too high an extruder temperature will cause excessive melting of the plastic and its leakage.

5. Layer offset

This is a fairly serious problem in 3D printing, the occurrence of which should alert the user. Such failures can signal problems with the electronic or mechanical components of the 3D printer. However, you may have set the print head movement value too high. Try lowering this parameter. You should also place the printer on a flat, stable surface and not touch it during operation. Excessive movement can cause the print head to shift.

6. Plastic is not feeding

This happens quite often, and it is no cause for concern. Possible causes:

Low extruder temperature;
Print speed too high;
Clogged nozzle;

First, try pushing the plastic through manually. If that doesn't help, reload the filament. Still no luck? Try changing the 3D printing settings and restarting the model. If that doesn't work either, it's time to clean the nozzle. Special needles of the required diameter are available for this purpose.

7. Cracks and layer splitting

This can happen both during and after printing. Sometimes it is due to poor-quality plastic, but more often the reasons lie elsewhere. Namely:

Too low printing temperature;
Too high layer height.

As you may have guessed, correcting these settings will help solve this problem.

Defects in 3D printing

We have listed the main problems in 3D printing. Of course, there are many more possible difficulties, but most of them can be solved by setting the correct values in the slicer. This is something you need to learn. With experience, you will understand how to adjust the required parameters and learn how to eliminate defects in 3D printing. That concludes our article.

What is the actual accuracy of a 3D printer?

3D printer accuracy

3D printer accuracy is one of the most important parameters that buyers pay attention to first. This is not surprising: the detail of future plastic products depends primarily on this factor. After all, everyone wants to get the highest quality models possible. The accuracy of a 3D printer refers to the minimum layer height applied during 3D printing. It would seem that everything is very simple. The higher the printing accuracy, the better the quality of the samples created. However, the declared accuracy of a 3D printer may differ from the actual quality of 3D printing. Why is this the case? There can be many reasons. Let's try to figure them out and clarify some unclear points.

3D printing accuracy

As mentioned above, 3D printing accuracy is the minimum acceptable layer height applied by a 3D printer. Modern FDM 3D printers can produce quality up to 20 microns, which is actually very good. But to actually obtain samples of such accuracy, certain conditions must be met.

First, you need to set all the print settings correctly. This is not an easy task, considering that the parameters are individual for each specific type of plastic and 3D model.
Second, you need to ensure the correct operation of the 3D printer, calibration of the table, and temperature control.
Third, you need to select the optimal plastic for 3D printing. The properties of different materials can vary, and not every plastic will provide the required accuracy of the 3D printer.

These are the main points to pay attention to in the pursuit of high-precision 3D printing, but they are not the only ones. Let's continue exploring this topic.

Print accuracy on a 3D printer

First and foremost, the accuracy of printing on a 3D printer depends on the 3D printer itself. Yes, it depends on the technical characteristics, and not only on the layer height specified in the device description. The accuracy of a 3D printer depends on a number of factors, including, in particular, the mechanical layout of the device. For example, devices with a closed housing demonstrate much better 3D printing accuracy than their counterparts with an open housing. This is due to a more uniform temperature inside the printer. Thanks to the absence of temperature differences, it is much easier to achieve high-quality reproduction. And, of course, high-quality 3D printers guarantee faster and less problematic results.

Interesting facts about 3D printers and 3D printing

The most interesting facts about 3D printing and 3D printers

3D printing technology is highly versatile and is often used for rather unusual purposes. Of course, this leads to interesting results that attract a lot of attention. But not all events are covered, and some achievements remain behind the scenes. We believe this is wrong, and in this section we want to list some interesting facts about 3D printing that you may not have known. We will tell you about things that go beyond the usual applications of 3D printing but are nevertheless of great practical value.

Interesting facts about 3D printing

First, let's list some interesting facts about 3D printing. Of course, there are many more points that could be included here. It all depends on people's awareness. After all, today everyone knows that 3D bioprinters can be used to create artificial organs and living tissues, as well as a lot of other similar information. Therefore, we have chosen revolutionary techniques that are only gaining popularity and are of particular interest and value in certain circles.

1. 3D printing of all-in-one tablets

In the US, epilepsy tablets printed on a 3D printer are already available in pharmacies. And scientists do not intend to stop at producing just one drug. Currently, new methods of 3D printing medicines are being developed, with researchers paying particular attention to SLA technology. The main advantage of using 3D printing for this purpose is the ability to gradually release active substances. In other words, such a tablet can be programmed to dissolve sequentially over a certain period of time. If you need to take several different medications a day, this could be a real breakthrough in treatment.

2. 3D printing of food

You probably already know about this, but it's worth talking about in more detail. Today, this branch of 3D technology is not very developed, but progress is moving rapidly. There are already several restaurants serving 3D-printed food, and some chefs are using 3D printing to bring their creative ideas to life. In addition, the production of food using a 3D printer is a real prospect for astronauts. After all, with the help of 3D printing, it is possible to enrich food with the maximum amount of nutrients and serve it in the most convenient form.

3. 3D printing of living tissues

Interesting facts about 3D printing are simply inconceivable without this point. 3D bioprinting is a real panacea in the world of medicine. With its help, scientists intend to create full-fledged living tissues suitable for implantation into the human body. Experiments are currently underway to manufacture artificial organs, bones, blood vessels, and even hair using living cells. And such endeavors are extremely successful! Of course, we are still a long way from mass 3D printing of fully functional organs, but we are definitely moving in the right direction.

4. Space

3D printing promises to become the main technology in space. With its help, people will not only conquer the vastness of the universe, but also explore new territories. 3D printing is used to produce parts for rockets, satellites, and other spacecraft, and the ISS even has its own 3D printer that operates in zero gravity. Moreover, 3D printing is seen as a potential technology for creating human settlements on the Moon and Mars. Who knows how far 3D technology will take us.

Interesting facts about 3D printers

The facts about 3D printing don't end there, but we decided to highlight some of them in a separate section. Here we will list some interesting facts about 3D printers that you may not have known.

1. Industrial robotic manipulators

This approach is increasingly being used in manufacturing: industrial robotic manipulators adapted for 3D printing are used as 3D printers. This is interesting primarily because the build area in such cases is practically unlimited by dimensions or the X, Y, and Z axes. Some companies even position this approach as “5D printing,” with the working platform also in motion. Recently, a concept for a six-axis 3D printer was presented, allowing products to be printed without supports.

2. Tattoo machine from a 3D printer

Tattoo artists immediately noticed the possibilities of 3D printing and decided to use it for their own purposes. Today, there are several projects for using 3D printers as tattoo machines, and their results are quite successful. Needless to say, this application is extremely specific and is unlikely to become widespread. But the idea is interesting.

3. Huge 3D printers and printers for smartphones

3D printing technology is characterized by extremes like no other. This is due to the enormous functionality of the technique, which allows it to be used in a wide variety of areas. 3D printers are used to print houses, huge metal structures, and other large-scale constructions. At the same time, developers are also working on the production of smaller parts. For example, the whole world is eagerly awaiting the 3D printer for smartphones, the concept of which took Kickstarter by storm some time ago. Scientists are printing microscopic structures and complete electronics, giving professional manufacturers a run for their money.

4. 3D printer with artificial intelligence

For such an unusual development, the aforementioned robot manipulator was used, for which not only the control code but also the artificial intelligence algorithm was written. As a test, the 3D printer printed an impressive 4-meter structure: a designer pavilion. The developers were satisfied with the result, but emphasized that this was only an experiment and that the methodology needed further optimization.
