What Can QIDI Max4 Combo Do?

The QIDI Max4 combo is a large-scale, high-temperature 3D printer with a 390X390X340 mm build volume, designed for professional and industrial applications. It features an active, heated chamber reaching 65°C for warp-free printing of advanced materials, a high-flow hotend capable of 370°C, and an AI-powered camera system for real-time print monitoring and failure detection. Other key features include CoreXY motion, Klipper firmware, direct drive extrusion, and a flexible dual-sided PEI build plate.

  • Active Cooling Air Control System

    In combination with active chamber heating, ensure that large-sized PLA does not warp at the edges.

  • 65ºC Chamber Heating

    Third-Gen Active Chamber Heating Reaches up to 65ºC. The air circulation design ensures ideal conditions for printing various filaments.

  • No Wobble, No Ripple

    With the shortest Z travel in its class, a 2 mm lead Z-axis screw delivers unprecedented precision. With the new anti-backlash nut, every layer stays perfectly aligned.

  • Heated Bed Enters the Industrial-Grade Temperature Control Era

    The 390×390 mm heated bed features a full-surface silicone layer with dense heating wires and insulation cotton, ensuring even heat, strong first-layer adhesion, and stable temperatures—perfect for large, warp-free prints.
