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.

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.

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).

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!

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.

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 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!

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!

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.

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.

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.
