QIDI Max4 Combo – Industrial Performance in a Desktop Format

QIDI Max4 Combo represents a top-tier large-format CoreXY 3D printer for demanding users, companies, and production facilities that need large volume, high speed, and full temperature control.

With a build space of 390 × 390 × 340 mm, an actively heated chamber up to 65 °C, and a high-temperature nozzle of 370 °C, the Max4 handles printing not only standard materials but also advanced technical filaments such as PA, PC, ABS/ASA, or carbon and glass fiber reinforced composites without compromise.

The Combo variant adds extended equipment and is ideal as a comprehensive "all-in-one" solution for professional use.

Main Advantages of QIDI Max4 Combo

• Huge build volume 390 × 390 × 340 mm – ideal for large functional parts, jigs, fixtures, and small series.
• CoreXY kinematics and full metal frame – high rigidity, precision, and stability even at high speeds.
• Speed up to 800 mm/s, acceleration up to 30,000 mm/s² – FOC closed-loop stepper motors and linear guides for fast and precise production.
• 1. generation actively heated chamber up to 65 °C
  – minimizing warping and delamination for large parts made of ABS, ASA, PA, PC, and composites.
• High-temperature bimetallic nozzle 370 °C – printing of demanding technical and filled filaments.
• Heated bed up to 120 °C with an aluminum base and silicone heater – fast heat-up and extremely uniform heating.
• Double-sided textured PEI flexible sheet – excellent adhesion and easy removal of prints by bending the sheet.
• AI camera in the print chamber – print monitoring, remote control, and better quality assurance.
• Active Cooling Air Control System – air flow management for a combination of heated chamber and targeted cooling, also suitable for large PLA prints.
• Ready for multi‑color / multi‑material – compatibility with the QIDI Box system for multi-color and multi-material printing.

Printing Possibilities and Materials

QIDI Max4 Combo is designed as a high-temperature industrial FDM printer that can handle a wide range of filaments:

• Standard materials: PLA, PETG, TPU
• Engineering plastics: ABS, ASA, PA (Nylon), PC
• Composites: carbon and glass fiber (CF/GF filled filaments)

Thanks to the combination of a 370 °C nozzle, 120 °C bed, and 65 °C chamber, you can safely print large and mechanically stressed parts without deformation or layer cracking.

Construction and Mechanics

• CoreXY movement – fast and quiet system with minimized mass in the Z-axis.
• FOC closed-loop stepper motors – higher precision, lower risk of lost steps.
• Linear guides on the X-axis and steel linear shafts on Y/Z – long-term precision, low friction, and smooth operation.
• 1.5GT timing belts – higher tooth density for finer movement and reduction of vibrations (VFA).
• Dual Z-axis screw (2mm lead screw) with anti‑backlash nut – stable lifting of the large bed.

Temperature Control and Surface Quality

• Active chamber heating up to 65 °C – essential for large technical plastic parts.
• Active Cooling Air Control System – precisely controlled air flow prevents hotend overheating while allowing printing in a warm chamber.
• Polar Cooler (included in Combo) – intensive extruder cooling for trouble-free printing of sensitive materials (e.g., PLA) in an enclosed chamber.
• Vibration optimization and resonance compensation – significantly better surface quality even at high speeds.

User Comfort and Software

• Enclosed and partially insulated all-metal cabinet – safe and quiet operation.
• AI camera in the chamber for remote print monitoring.
• Intuitive touch control and calibration guide.
• Automated or significantly simplified nozzle height and bed leveling calibration using a new generation leveling sensor.
• Support for QIDI Print / QIDI Box slicer with preset profiles for a quick start and optimal results.

Typical Use

• Prototyping and development – fast production of large functional prototypes.
• Jigs and tools production – durable parts made of PA‑CF, ABS/ASA, PC for industry.
• One-off and small series production – repeatable production of end-use parts.
• Education and R&D – universal machine for experiments with a wide range of materials.
