QIDI Max4 Combo — a CoreXY 3D printer for large parts
QIDI Max4 Combo combines a 390 × 390 × 340 mm build volume with an enclosed frame and an actively heated chamber up to 65 °C. The nozzle reaches 370 °C and the bed reaches 120 °C. It suits prototypes, housings, fixtures and small production batches using standard and engineering filaments.
This package includes the Max4 printer and the QIDI Box multi-material unit. The standard build surface is a double-sided magnetic PEI plate, and the standard nozzle is 0.4 mm. Polar Cooler is a compatible additional module for cooling the extruder.
Motion system and performance
The CoreXY mechanism uses 1.5GT belts and FOC closed-loop motors. Maximum toolhead speed is 800 mm/s, with acceleration up to 30,000 mm/s². Choose printing profiles to suit the material, geometry and nozzle flow. These maximum figures do not represent a constant printing speed for every model.
Automatic levelling uses a loadcell sensor integrated into the hotend. The printer includes input shaping, filament run-out detection and power-loss recovery. Its camera supports monitoring and timelapse at up to 1080p, while AI features detect certain printing problems.
Materials and multi-colour 3D printing
Max4 uses 1.75 mm filament, including PLA, PETG, ABS, ASA, TPU, PA, PC and suitable carbon- or glass-fibre composites. Select a nozzle and profile appropriate to the exact material. Feed flexible filaments according to QIDI's instructions; printer compatibility does not automatically mean QIDI Box compatibility.
One QIDI Box feeds up to four filaments. Connecting up to four boxes enables up to 16 colours or materials; additional boxes are purchased separately. The unit supports drying up to 65 °C and automatic reloading of compatible filament. Drying settings must suit the material.
Control and everyday use
Use the 5-inch touchscreen, Wi-Fi, Ethernet or USB. QIDI Studio provides model profiles; OrcaSlicer and PrusaSlicer are also supported, although individual features depend on the software. Slicer formats include STL, OBJ, 3MF and STEP/STP.
The chamber filter combines a G3 pre-filter, H12 HEPA and activated carbon. Allow suitable ventilation and clearance around the printer. Follow the manufacturer's profiles for PLA, engineering materials and cooling; active chamber heating is not appropriate for every setup.
