Product Description

The MINGDA MD-400D pairs a rigid CoreXY frame with independent dual extrusion (IDEX) to give engineering teams a faster path from CAD file to finished part. Two independently driven print heads let you run two colors, two materials, or a build material paired with dissolvable support at the same time — with mirror and duplication modes that double your output per print. A peak acceleration of 10,000 mm/s² and speeds up to 300 mm/s (0 to top speed in just 0.02 seconds) cut hours off large or batch prints without sacrificing the ±0.1 mm accuracy this machine is built for.
Underneath, a self-developed 64-bit, 6-core motherboard with 32 GB of onboard memory runs on Klipper firmware for smooth, high-speed motion control. The fully enclosed 400 × 400 × 400 mm chamber holds a stable print environment for warp-prone engineering materials, and the dual hotend setup — a 250°C standard hotend and a 350°C all-metal, hardened-steel nozzle — opens the door to 10+ filament types, from everyday PLA and PETG to demanding composites like PET-CF, PA12-CF, and ABS-GF25.
