3D Printer DOWELL 3D DL 12 | Enclosed Chamber

3D Printer DOWELL 3D DL 12 with Enclosed Frame

DOWELL 3D DL 12 with a print volume of 1200 × 1200 × 1200 mm is an industrial FDM printer with an enclosed frame, designed for manufacturing large-scale prototypes, automotive parts, furniture production, and sculptures. The enclosed frame configuration supports an internal chamber temperature of up to 60 °C, creating stable conditions in the work area. This reduces the risk of warping and delamination during the printing of large-scale models. The dual-stage extruder heating system up to 420 °C and extrusion speed up to 1000 g/h are designed for forming massive objects.

Technical Features of the Enclosed Frame

Forming parts from high-temperature polymers requires maintaining a constant temperature throughout the entire printing cycle. The enclosed frame with heating up to 60 °C implements this range of functions.

• Geometry Stability: A constant temperature in the chamber reduces thermal fluctuations during the deposition of new layers, helping to prevent shrinkage and distortion of the product.
• Material Compatibility: The list of compatible filaments includes PLA, PETG, ABS, ASA, TPU, PVA, PP, PC, PA, as well as composites with carbon and glass fiber CF/GF with a diameter of 2.85 mm.
• Protection from External Influences: The frame isolates the work area from room temperature fluctuations and drafts.

Construction and Mechanics

The structural base of the series is designed for long-term operational loads.

• Load-Bearing Frame: The frame made of 80 mm thick aluminum profile ensures rigidity and stability during 3D printing.
• XY Axes: Built on industrial motion modules and designed for printing speeds up to 500 mm/s.
• Z Axis Drive: A mechanism with a 20 mm screw and a geared motor ensures precise platform positioning.
• Automatic Table Locking: Locks the platform and holds its position in case of power outages, vibrations, or external mechanical impacts.

Extruder System Parameters

The model is equipped with an extruder with dual-stage heating for 2.85 mm diameter filament with a material feed rate of up to 1000 g/h.

• Temperature Range: The nozzle heats up to 420 °C, allowing the use of standard and technical filaments.
• Interchangeable Nozzles: Designed to work with nozzles diameters of 0.8, 1.2, and 1.6 mm for printing large-scale models.

Working Platform Characteristics

• Table Construction: The platform consists of a 6 mm tempered glass cover and a silicone heating panel. The tempered glass withstands deformation loads and ensures uniform heat transfer.
• Temperature Modes: The worktable heats up to 100 °C in the standard version, with options available for heating up to 150 °C and PEI coating.

Automation and Interface

• Automatic Leveling: The table plane detection system compensates for deviations during calibration.
• Sensors and Recovery: The filament sensor monitors material availability, and the auto-recovery function allows printing to continue after power is restored.
• Control and Monitoring: The device is equipped with a 10-inch color touchscreen display. The Wi-Fi module is intended for remote control, and a camera connection is also provided for process monitoring.

Operational Control Tools

During printing, the operator can adjust speed, extrusion ratio, and cooling intensity. The display shows temperature change graphs, task execution status, and G-code. Available settings include Z-offset, job history viewing, and an emergency stop button.

Applications

The dimensions of the printer's work area allow it to be used for manufacturing industrial enclosures, engineering components, auto-tuning parts, furniture elements, as well as models and sculptures.

Technical Specifications

Modifications and Equipment Configurations

The DL line includes models with different production volumes. For working with engineering materials, modifications with an enclosed frame and chamber temperature control are provided. For tasks requiring the use of standard plastics or direct access to the part during printing, the series includes 3D printers with an open frame.
