3D printer QiDi Max 4 Combo — desktop FDM 3D printer, dual extrusion capable, touchscreen control, enclosed build chamber

QiDi Max 4 Combo is a desktop FDM 3D printer built for reliable prototyping and small-batch production. The printer combines a large enclosed build chamber with dual-extrusion capability and touchscreen control, enabling multi-material or multi-color prints while maintaining a stable thermal environment. CoreXY mechanics, high-temperature extrusion and active chamber heating support a wide range of filaments from PLA to engineering materials, making the device suitable for engineering prototypes, functional parts, educational projects and advanced hobbyist use.

Advantages

The Max 4 Combo provides a large build volume that allows printing of sizeable models in one piece, reducing assembly and improving part strength. High nozzle temperatures (up to 370°C) and a third-generation active heated chamber (up to 65°C) make it possible to print demanding materials such as PC and fiber-reinforced composites. A robust CoreXY frame, closed-loop FOC motors and reinforced motion components deliver fast, repeatable and precise printing. The printer also includes features that simplify operation and monitoring, such as automatic bed leveling, filament sensing, a 5" touchscreen, onboard camera and multi-stage air filtration.

Suitable for

• Engineering prototypes and functional parts requiring high strength and temperature-resistant materials
• Large-format models and single-piece prints up to 390 × 390 × 340 mm
• Multi-material or multi-colour prints using dual extrusion
• Educational labs and maker spaces teaching advanced FDM workflows
• Hobbyists working with technical filaments like PC, PA and carbon-fiber composites

Когда это может быть не подходящим решением

QiDi Max 4 Combo — это крупногабаритный настольный принтер весом около 40 кг и размером более полуметра по каждой стороне, поэтому он может быть громоздким для ограниченных по пространству рабочих мест. Для простых задач с небольшими деталями или редким использованием базовых PLA-печатей более компактные и бюджетные модели могут быть предпочтительнее.

How to use

Place the printer on a stable, level surface and ensure adequate ventilation for the enclosure. Install filament spools on the provided holders and route filament through the pneumatic fittings into the direct-drive extruders. Use the touchscreen to connect to Wi‑Fi or Ethernet and load the desired print file in supported formats (STL, OBJ, 3MF, STEP). Run automatic bed leveling using the load cell sensor before the first print and preheat the nozzle and chamber to temperatures appropriate for the chosen material. Monitor prints via the onboard 1080p camera or the touchscreen, and make use of filament end detection and print-resume features to reduce failed prints.

What to consider before purchase

• Physical size and weight (printer dimensions and ~40 kg) — ensure sufficient workspace and access
• Power requirements and rated power for chamber and bed heating — confirm compatibility with local mains
• Required ventilation and safety policies when printing high-temperature or composite filaments
• Availability of suitable filaments and potential need for additional hardened nozzles for abrasive composites
• Software compatibility — supports QIDI Studio, OrcaSlicer, PrusaSlicer and other slicers

Usage recommendations

For reliable results with engineering filaments, use recommended temperature profiles, enable active chamber heating for materials prone to warping, and schedule regular maintenance of the hotend and motion components. When printing composite or abrasive filaments, consider hardened nozzles and adjust retraction and print speeds to match material behavior.
