Printing finer complex prototypes and double productivity are why you need the MD-400D Independent Dual Extruder 3D Printer for your business.


Infinite Possibilities with IDEX

IDEX in Dual-material Printing

Compared with a multi-material unit, IDEX dual-material printing requires less time in filament changing and creates less waste. Plus, IDEX offers the cleanest two-extruder solution that prevents cross-contamination. It creates a clean interface between two materials, embracing hassle-free removal and avoiding stains and weird blending along the seam.

Breakaway Support Filament

Much easier to remove the support, the supported surface comes out clean and smooth.

Soluble Support Filament

Printing complex models with internal geometries and hollow structures is made possible by using water-soluble filament.


Dual-material Prints. In one print, you make the most of two sets of properties. Combine the strength of PETG with the flexibility of TPU for functional parts that can stand daily wear and tear impressively. Print also multi-part objects as a whole. With no assembly, the object attains stronger interconnections, making it less prone to impairment.

Dual Color Prints. Add a splash of personality to your concept models, miniatures, party essentials, gift items, and home decor.

Use different materials on the walls and the infill. By printing infill with economical materials plus a large-diameter nozzle, you can now spend most of your time and money budget on working the exterior to perfection.

High-precision Linear Rails

The industrial-grade linear rails are made by CNC grinding at the micron level, ensuring smooth and steady movements. A significant rise in precision, rigidity, and durability for you to savor a fast, accurate, and steady making experience.

Innovative IDEX calibration

XY Axis Offset Calibration

Fine-tune the XY axis to align the nozzle center of the right extruder with the origin of the XY axis.

Z Axis Offset Calibration

Fine-tune the Z axis to align the nozzle center of the right extruder with the origin of the Z axis.

New Cooling System Design

The dual cooling system truly takes model cooling to the next level with anaerodynamic air duct design that blasts models with intensely powerful directedairflow for enhanced cooling capabilities, crafting perfect prints.

Free Leveling

The automatic leveling system greatly 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.

PEI Flexible Printing Platform

It has strong adhesion, high temperature resistance, and is suitable for various consumables. It can be easily removed by bending.

Quick Heating Hotend

Max temperature of hotend is 350°C. It can be heated to 200°C in about 40 seconds; The heating speed remains unchanged at 220V and 110V voltages.

MINGDA Self-developed Core Hardware Delivers Speedy Smooth Performance.

This high-performance 64-bit self-developed motherboard, powered by the 6-core CPU, ensures fast processing of data and rapid completion of 3D printing tasks. With 32GB of memory, you can quickly store, export, and print large files with ease.

7-inch IPS High-definition Large Screen

MD-400D has a 7-inch IPS  high-definition computer screen. Compared with traditional LCD screens, it can see bright, saturated, and natural high-quality images from any angle. At the same time, it is more environmentally friendly and saves electricity.

Support multiple languages

Self Check when Power on

When power on it can automaticly check the status of the extruder, hot bed, camera, automatic leveling, fan, and other components; If there are any abnormalities, a prompt will be displayed on the printer screen for quick and convenient processing.
