QIDI Max 4 Combo is a powerful enclosed 3D printer for large models and engineering materials. It offers a large build volume of 390 × 390 × 340 mm, a nozzle up to 370 °C, and an actively heated chamber up to 65 °C for stable results even with demanding filaments. Thanks to the CoreXY design, closed-loop motors, and robust cooling, it prints fast, accurately, and reliably.
Large build volume for big projects
The 390 × 390 × 340 mm workspace lets you print large models in one piece, without splitting and subsequent gluing. It saves time, increases part strength, and simplifies post-processing.
Print engineering materials thanks to a 370 °C hotend
The print head with temperatures up to 370 °C is suitable for a wide range of filaments—from common PLA and PETG to PC, PA, and composites. The ceramic throat and improved heat dissipation help maintain stable flow and reduce the risk of clogging at high temperatures.
Convenient control and remote monitoring
The enclosed design, a 1080p camera, and network connectivity (Wi‑Fi/Ethernet) enable easier print monitoring. Also practical are print resume after a power outage and a filament runout sensor for safer operation.
The QIDI Max 4 Combo 3D printer is designed for users who want to print large parts in one piece while also needing a stable environment for materials prone to warping. The enclosed chamber with active heating helps minimize warping and improves surface quality, while the high-temperature hotend opens the door to printing advanced engineering filaments.
Key benefits:
- Large build area 390 × 390 × 340 mm for large-format 3D printing without splitting the model.
- Hotend up to 370 °C for PLA, PETG, and demanding materials (e.g., PC, PA, and composites).
- Active chamber heating up to 65 °C (3rd generation) and air circulation for stable printing.
- High speed up to 800 mm/s and acceleration up to 30,000 mm/s² while maintaining accuracy.
- Automatic bed leveling using a strain-gauge sensor integrated in the hotend.
- Safer and more convenient operation thanks to the filament sensor, print resume after an outage, and a 1080p camera.
- 3-in-1 air filtration (G3 + HEPA H12 + activated carbon) for a cleaner environment around the printer.
Operation is handled via a 5" touchscreen and connectivity via Wi‑Fi, Ethernet, or USB. Supported formats (STL, OBJ, 3MF, STEP, STP) and compatibility with slicers such as QIDI Studio, OrcaSlicer, or PrusaSlicer make it easy to integrate into your workflow at home or in the workshop.
