Closed 3D Printer Dowell DF 12
Dowell DF 12 1200 × 1200 × 1200 mm is an industrial FDM printer in a closed metal case, designed for large-scale prototyping, manufacturing massive models, complex engineering components, and serial production of parts. The model is designed for high-flow printing of large objects: thanks to extrusion performance up to 1000 g/h and a high-speed nozzle, it manufactures integral large-scale structures significantly faster than other models in the series, eliminating the need to split parts into sections and subsequently glue them. Thanks to the extruder heating up to 350 °C, printing speed up to 500 mm/s, and positioning accuracy of 0.002 mm, the equipment ensures precise geometry reproduction and stable repeatability of results.
Advantages of a Closed Case and All-Metal Construction
Working with large-scale objects and technical filaments requires frame rigidity and microclimate control throughout the entire 3D printing cycle. The closed sheet metal case solves key technological challenges.
- Prevention of shrinkage and deformation: the all-metal closed case protects the working area from thermal fluctuations when new layers are deposited, preventing warping, delamination, and ensuring interlayer adhesion and corner geometry of the product.
- Working with engineering plastics: the closed design allows printing complex-profile parts from thermoplastics with a high shrinkage coefficient, such as ABS, ASA, PC, Nylon (PA), and their composite fillers CF/GF.
- Protection from external factors and noise level: the closed case isolates the working volume from room temperature fluctuations and drafts in the workshop, reduces noise level during operation to 50 dB, and retains volatile compounds inside.
Kinematics and Structural Stability
The design of the 3D printer is calculated for prolonged loads at high movement speeds.
- Reinforced mechanics: structural profiles, optical axes, and lead screw shafts are thickened, ensuring structural rigidity and reducing vibrations during intensive printing.
- Platform positioning: 4 independent lead screw Z axes and kinematic mechanics ensure positioning accuracy up to 0.002 mm.
- Working noise level: thanks to the all-metal construction and control drivers, the noise level during operation does not exceed 50 dB.
Extruder with Heating up to 350 °C
The printer is equipped with a high-flow nozzle printing unit designed for accelerated material feed to reduce production cycle time.
- High-flow extrusion: the system provides a material flow up to 1000 g/h, allowing for building up walls of large-scale models without losing interlayer strength.
- Nozzle working temperature: heating up to 350 °C ensures compatibility with materials from basic PLA and PETG to technical ABS, ASA, TPU, PVA, PP, PC, Nylon, Wood, as well as carbon fiber (CF) and glass fiber (GF).
- Nozzle compatibility: supports nozzles with diameters of 0.8, 1.2, and 1.6 mm for 2.85 mm filament for high-speed printing and filling the internal volume.
Thermally Stable Working Platform
The stability of the geometric parameters of the part and the adhesion of the first layers are ensured by a glass surface with uniform heating.
- Glass platform: the smooth glass surface with calculated bearing capacity ensures flatness, resistance to deformation under massive models, cleaning, and separation of finished products after cooling.
- Heating up to 100 °C: the heating system distributes heat over the entire table area, preventing material detachment.
Automation, Smart Control, and Interface
The 3D printer is equipped with functions for autonomous operation in 24/7 mode and reducing the impact of the human factor.
- Automatic bed leveling: a calibration system with an accuracy of 0.002 mm, 4 independent Z-axis screws, and Z-offset compensation adjusts the plane before printing begins.
- Assisted filament feeding system: the feeding mechanism ensures continuous operation during long printing cycles, preventing material jamming or breakage.
- Work recovery functions: auto-recovery of printing after power failure, automatic temperature control, emergency stop button, and status sensors.
- Display and wireless control: 10-inch rotatable color touchscreen with support for 15 languages and built-in Wi-Fi module for remote control.
Operational Control Tools and AI Monitoring
- Video control and AI detection: built-in webcam and error detection system allow remote monitoring of the process and recording print deviations.
- Parameter adjustment: the ability to change printing speed, extrusion intensity, and cooling directly during operation.
- Visualization and code work: real-time temperature graph display, built-in G-code viewer, access to print history, and configuration file editing.
Applications and Types of Products
Thanks to the working volume, high-flow extrusion up to 1000 g/h, and steel frame, the 3D printer is used for manufacturing:
- large-scale industrial cases, equipment models, and protective covers;
- casting and forming molds, auto-tuning elements, bumpers, and conceptual prototypes;
- industrial latches, pipes, curved air ducts, and engineering units;
- molds for furniture production, interior elements, sculptures, and architectural models.
