Mingda MD-400D FDM 3D Printer – High-Speed Large-Format IDEX 3D Printer

The Mingda MD-400D is a powerful industrial-class FDM 3D printer designed for professional users who need precision, speed, and advanced multi-material capability. With its large 400 × 400 × 400 mm build volume, it supports the production of big prototypes, engineering components, functional parts, and batch manufacturing.

Equipped with independent dual extruders (IDEX), the MD-400D enables true dual-color, dual-material, duplication mode, and mirror printing — significantly increasing productivity and reducing manufacturing time. Each extruder supports high-temperature printing up to 350 °C, making the machine compatible with a wide range of engineering filaments such as Nylon, PC, ABS, CF-reinforced materials, and more.

Built with a rigid full-metal frame and high-precision motion system, the MD-400D delivers industrial-grade accuracy, smooth surface quality, and reliable long-duration performance. Its intelligent features include automatic bed leveling, filament sensor, resume-print function, and a user-friendly touchscreen interface, ensuring stable printing for demanding professional applications.

Ideal for rapid prototyping, product development, tooling, jigs, fixtures, architectural models, and multi-material production, the Mingda MD-400D is a versatile and high-performance solution for businesses, engineers, designers, and manufacturing environments.

Main Features:

Dual Extruders Working Independently

The dual extruders on the MD-400D work independently and are not bundled, allowing for flexible and precise control. When using only one extruder, the other extruder 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.

10 advantages

• 350 degrees direct extruder
• IDEX System 
• Dual colors & Dual Materials Mode 
• Duplicate & Mirror Mode 
• Fully Enclosed Metal Structure 
• Air Filtration System 
• Removable PEI Plate 
• Auto Leveling System 

Four printing modes 

1. Duplicate Mode: Equivalent to 2 printers working, achieve double productivity
2. Mirror Mode: Support printing symmetrical models while saving half the time
3. Support Mode: Print complex structural models, complex models can also be printed smoothly and with high precision 
4. Dual-Color Mode: Allows printing different parts of a model in 2 colors

Two temperature modes to meet different material requirements 

MD-400D is a flexible, high performance and commercial industrial 3D printer. It's equipped with two types of extruders, therefore various printing needs can be met selecting the matching module according to different types of filaments. 

Large build volume 

Printing size: 400x400x400mm meets most prototype printing needs 

Free leveling 

The automatic leveling system geatly improves printing efficiency and quality stability. It helps to reduce failed prints caused by an unleveled build plate. The precise calibration of nozzle distance also enables 3D printers to print models with finer layer resolution. 

Fully Metal Enclosed Structure 

The fully enclosed structure the MD-400D helps maintain temperatures printing with ABS and other advanced materials for high-quality prints. This reduces issues like model shrinkage, warping at conners, and broken filaments, ensuring good print results, high precision, and a high success rate. 

Flexible PEI Platform 

With good viscosity, the model is not easy to warp during the printing process and easy to remove after finished printing.

Air filtration system 

During the printing process, the air filtration system can effectively clean particles (including nanoparticles) in the air. The system operates silently to ensure a quiet working environment. 

Smart Resume Printing Function 

The machine can automatically resume printing after power-off, less worries on print failure.

Double Gears Direct Extruder

Double gears direct extruder with strong pushing force for more stable & accurate printing greatly reduces the risk of under extrusion.

5 inch Colorful Touch Screen 

Large screen, simple operation 

Automatic filament detection 

It will pause the printing process if the filament run out, or if the filament is broken

Compatible with various filaments 

• Common filament: PLA, ABS, TPU, PETG, ASA, etc
• Engineering filament: HtPA, PET-GF, PET-CF, PA12-CF, HTPA-GF, HTPA-CF, ABS-GF25, ABS-CF20, PA-GF25, PA-CF25, etc
• Support filament: S-Mulit, S-HtPA, PVA, etc
