IDEXIndependent dual extruders

Industrial Dual-Extrusion Printing Without Giving Up Build Volume

MD-400D is designed to make large-format dual-material printing practical for engineering teams, production departments, manufacturers, schools, and service bureaus.

400 × 400 × 400 mm Build Volume

Print larger prototypes, tooling, fixtures, housings, and production parts without splitting designs into multiple pieces.

MINGDA independent dual extruder toolheads

Independent Dual Extruders

Run two materials or two colors with independent toolheads, minimizing the purge waste and cross-contamination common to single-nozzle material-changing systems.

MINGDA IDEX parallel batch printing example

Copy & Mirror Modes

Produce two identical parts at the same time or print mirrored components in parallel for faster throughput and paired assemblies.

MINGDA MD-400D high-speed printing system

High-Speed Klipper Platform

Print at speeds up to 300 mm/s with peak acceleration up to 10,000 mm/s², supported by input shaping and flow control.

350°C Engineering-Material Hot Ends

Go beyond standard PLA and PETG with carbon- and glass-fiber reinforced engineering materials and dedicated support filaments.

Production-Focused Automation

Automatic leveling, filament detection, power-loss recovery, camera monitoring, WiFi connectivity, and power-on self-check reduce operator intervention.

Four Printing Modes, One Production Platform

The IDEX architecture gives the MD-400D flexibility that conventional single-extruder printers cannot match.

Single MaterialUse one extruder for conventional large-format FDM printing.

Dual Material / ColorCombine two colors, rigid + flexible materials, or model + support materials.

MINGDA independent extruders printing repeated parts

Copy ModePrint two identical parts simultaneously to increase output for batch production.

Mirror ModePrint left/right or mirrored components in a single production run.

MINGDA remote printing and multi-machine monitoring

Why IDEX Matters

Independent dual extruders move separately on the X axis. This allows the MD-400D to print with two materials or colors while keeping the unused nozzle away from the part. It also enables duplication and mirror workflows that can effectively turn one machine into a two-part production cell for appropriately sized models.

Copy-mode area: 400 (2 × 200) × 400 × 400 mm
Mirror-mode area: 320 (2 × 160) × 400 × 400 mm

Engineering Materials for Real-World Parts

With hot ends capable of reaching 350°C and a heated platform up to 110°C, the MD-400D supports both everyday polymers and higher-performance reinforced materials.

MINGDA MD-400D Frequently Asked Questions

What is the build volume of the MINGDA MD-400D?

The standard build volume is 400 × 400 × 400 mm.

What does IDEX mean on the MD-400D?

IDEX stands for Independent Dual Extruder. The two print heads can move independently on the X axis, enabling dual-material, dual-color, copy, and mirror printing modes.

Can the MD-400D print two parts at once?

Yes. Copy mode can print two identical parts simultaneously, while mirror mode can produce mirrored left/right components in one job.

How fast can the MD-400D print?

MINGDA lists a maximum print speed of up to 300 mm/s and peak acceleration up to 10,000 mm/s². Actual production speed depends on the material, geometry, nozzle, layer height, and quality requirements.

What materials can the MD-400D print?

Published compatibility includes PLA, TPU, PETG, reinforced PET and high-temperature PA materials, ABS-GF25, and support materials such as PVA, S-Multi, and S-HtPA.

Can the MD-400D print carbon-fiber materials?

Yes. MINGDA lists multiple carbon-fiber and glass-fiber reinforced engineering materials. The correct nozzle, drying procedure, and process settings should be selected for the specific filament.

Does the MD-400D have automatic bed leveling?

Yes. The MD-400D includes automatic leveling to improve setup consistency and reduce failures related to an uneven first layer.

Can I monitor the MD-400D remotely?

Yes. MINGDA lists camera and WiFi/network functionality for remote printing and real-time monitoring.

What software does the MD-400D use?

MINGDA lists MINGDA OrcaSlicer as the supported slicing software and Klipper as the printer firmware.
