3D Printer DOWELL 3D DM 12 Pro | Open Frame

Open 3D Printer Dowell DM 12 Pro

Dowell DM 12 Pro Open Frame is an industrial open-type FDM printer with a working area of 1200 × 1200 × 1200 mm, designed for the production of large-scale prototypes, furniture molds, sculptures, and engineering components.

The model belongs to the DM Pro series — high-performance equipment, as it supports high-flow material extrusion, printing speeds from 250 to 500 mm/s, and extruder heating up to 420 °C thanks to a two-stage heating system. The significant build volume allows for the creation of solid products without further cutting the model into separate parts and without subsequent gluing.

Kinematics and Structural Stability

The basis of the design is a reinforced aluminum profile with a thickness of 60 mm, which ensures the stability of the geometric parameters of the frame under prolonged working loads. Precision positioning accuracy is achieved through professional mechanical units:

• The XY axes are based on high-precision modular guides, ensuring smooth and stable movement at speeds from 250 to 500 mm/s.
• The Z-axis is equipped with screw shafts with a diameter of 16 mm and geared motors, providing precise layer step control and withstanding heavy loads from massive parts.
• The table's self-locking mechanism prevents unintentional shifting or falling of the platform along the Z-axis in case of sudden power outages.

High-Performance Extruder

The two-stage extruder heating system is designed for an intensive material feed flow of up to 1000 g/h, ensuring high wall formation speed without losing interlayer strength.

• Working with thick filament 2.85 mm and nozzle heating up to 420 °C allows the use of a wide range of materials, including PLA, PETG, ABS, ASA, TPU, PVA, PP, PC, PA, as well as high-filled composites with carbon fiber and fiberglass.
• The ability to install nozzles with diameters of 0.8 mm, 1.2 mm, and 1.6 mm allows adapting the printing process for tasks with high detail or for quick filling of internal volumes of large models.

Thermally Stable Platform

Reliable adhesion of the first layers and stability of geometric shapes are ensured by a combined working surface with a specialized heating element.

• The working surface consists of tempered glass with a thickness of 6 mm and a silicone heating panel, providing quick and even heat distribution across the entire plane for easy separation of the product after cooling.
• The working temperature of the platform reaches 100 °C in the basic version, with an optional modification available with heating up to 150 °C and PEI coating to minimize material shrinkage when printing with technical plastics.

Automation, Remote Monitoring, and Interface

To ensure stable operation without the need for constant operator presence, the printer has a wide range of control functions.

• The automatic calibration system performs multi-point scanning of the table plane and compensates for micro-unevenness before starting printing.
• An integrated camera and Wi-Fi module allow remote monitoring of the printing status and equipment control over the network.
• The filament sensor pauses the process in case of the end or breakage of the 2.85 mm thread.
• The print recovery function allows resuming the process from the stopping point after power supply restoration.
• Control is carried out using a 10-inch color touch screen with a clear graphical interface.

Operational Control and Monitoring Tools

• Adjusting speed, extrusion coefficient, and cooling intensity directly during the printing process.
• Visualization of the current status and dynamics of temperature indicators in real-time.
• Built-in program for viewing G-code and the ability to edit device configuration.
• Setting Z-axis offset during task execution and saving work history.
• A separate emergency stop button on the body for quick power-off of executive mechanisms.

Examples of Finished Products

The extrusion system's productivity allows the printer to be used in the following areas:

• production of outdoor advertising elements, design objects, and sculptures;
• printing of car tuning elements, bumpers, and large-scale models for the automotive industry;
• manufacturing of industrial screws, master models for casting, and casting molds.

Technical Specifications

Available Line Modifications

The model range offers variants of 3D printers in an open case with different platform sizes — from 800 × 800 × 600 mm to 1200 × 2000 × 2000 mm. For technological tasks involving materials with a high shrinkage coefficient, modifications with a fully enclosed metal case are also provided.
