Print quality

The Mingda MD-400D can produce high-quality prints with smooth surface finish. Due to its IDEX design with independent dual extruders, the machine is capable of printing with easy-to-remove and soluble support filament and can effectively build complex models with overhangs, bridges, internal geometries, and hollow structures.

The IDEX system of the MD-400D allows for flexible and precise control of both extruders. When using a single extruder, the other one is moved away from the print area to prevent unwanted filament overflow onto the printed object. However, the extruders can also work simultaneously and independently if higher productivity is required.

The double gears direct extruder with strong pushing force for more stable and accurate printing greatly reduces the risk of under-extrusion. With the flow rate of up to 40 mm³/s and maximum print speed of 500 mm/s, the Mingda MD-400D is 5X faster than competing printers, which significantly cuts production times. Featuring acceleration of up to 10000 mm/s², which means only 0.02 s from 0 to 300 mm/s, the machine is capable of printing large-scale models in a day.

For example, this helmet (266 x 210 x 130 mm) was printed by the Mingda MD-400D with PLA-HF and PVA at the speed of 250 mm/s in just 34 hours. Regular large-format FDM printers on the market, with a printing speed of 50 mm/s, would print the same model in 4 days.

Crafted with an all-metal enclosed chamber and modular guide rail structure, the printer not only maintains a consistent printing temperature, but also ensures structural stability and precision of the printing process (up to ±0.1 mm).

To eliminate ghosting and ringing issues, the machine is engineered with the self-developed vibration reduction feature that automatically compensates the vibrations during the high-speed printing process. In addition, the flow control mechanism allows precise management of the amount of filament, eliminating under- and over-extrusion. This leads to improved print quality and accuracy with sharper details.

The MD-400D incorporates an automatic leveling system, which greatly improves printing efficiency and quality stability as well as helps to reduce failures caused by a poorly leveled build plate. The precise calibration of nozzle distance also enables the printer to create models with finer layer resolution.

Also, the machine boasts a flexible PEI platform. Due to its impressive viscosity, the build plate provides strong adhesion, high-temperature resistance, and support of various consumables. Moreover, it aims to prevent model shrinkage and warping at corners and allows for effortless removal of completed prints by simple bending.

As a high-temperature IDEX 3D printer, the MD-400D offers four printing modes that make it both versatile and capable of tackling numerous projects. Thus, with the Duplicate mode, one can print two identical models at once. The Mirror mode creates symmetrical models and saves significant time. The Dual-Color mode implies printing a single model in two colors, giving more creative freedom. Finally, the Support mode assists in printing complex structural models using both high-performance and breakaway filaments. This simplifies support removal, ensuring a smooth and successful printing experience.

Last but not least, the machine has a powerful dual cooling system with an aerodynamic air duct design that ensures quick and complete cooling of each layer at high speeds. This offers exceptional molding accuracy as well as reduced risks of stringing and warping.

Materials

The Mingda MD-400D is equipped with a high-temperature dual-gear direct extruder that gives it a unique ability to handle flexible and engineering filament. Moreover, the machine is built to accommodate both high-temperature and common hotends. The maximum temperature of the basic hotend can reach 250 °C, supporting popular consumables like PLA, ABS, PETG, TPU, and other advanced materials.

Thanks to the all-metal hotend and hardened steel nozzle capable of heating up to 350 °C, the MD-400D model can reliably print with a wide range of engineering and composite filaments, including PET-carbon fiber, PET-glass fiber, Nylon carbon fiber, Nylon glass fiber, and more ensuring high dimensional accuracy and surface quality of the printed parts. There is no need to replace the hotend when switching between different material types. Furthermore, the IDEX structure enables multi-color and multi-material printing with support filaments, such as S-Multi, S-HtPA, PVA, etc.

Apart from this, the MD-400D is equipped with a quickly heated aluminum alloy platform with the maximum temperature of 110 °C. Evenly heated and capable of reaching 60 °C in about 75 seconds, it makes for strong first layer adhesion and overall print quality. The heating speed remains unchanged at 220V and 110V.

Build volume

The Mingda MD-400D 3D printer offers a capacious build area of 15.8 x 15.8 x 15.8 inches (400 x 400 x 400 mm) in the free printing mode. Unlike other IDEX 3D printers, it also offers a substantial workspace in the Duplicate and Mirror modes (400 x 400 x 400 mm and 320 x 400 x 400 mm respectively). This volume meets most prototype printing needs and lets you produce models of various sizes, including fairly large ones, without the need of splitting them and in batches, which makes for time-saving and increased performance.

Printer controls and software
