Qidi Max4: Industrial-Grade Large-Format 3D Printer
Break the size barrier with the Qidi Max4, the ultimate powerhouse in the Qidi lineup. Engineered for massive scale without sacrificing professional precision, the Max4 combines a colossal build volume with industrial-grade stability. Whether you are printing full-scale automotive prototypes or high-strength aerospace components, the Max4 is built to handle the biggest challenges in 3D printing.
Why the Qidi Max4 is the New Benchmark
The Max4 is a completely redesigned flagship featuring Closed-Loop Motors and an optional Polar Cooler system to ensure that large-scale prints maintain perfect accuracy from the first layer to the last.
-
Massive Build Volume (390 x 390 x 340 mm): With 55% more space than its predecessor, print large functional parts in a single piece, reducing assembly needs and increasing part strength.
-
FOC Closed-Loop Stepper Motors: Experience industrial-level precision and reliability.
-
Active Chamber Heating (Up to 65°C): Essential for engineering materials like ABS-CF, PC, and Nylon, preventing warping and ensuring superior layer adhesion.
-
Blistering Speed & Flow: Reach print speeds up to 800mm/s with an acceleration of 30,000mm/s². The high-flow hotend (40mm³/s) ensures consistent extrusion.
-
Ultra-Stable Z-Axis: Large lead screws and an anti-backlash nut deliver a flagship-level surface finish with zero Z-wobble.

Industrial Performance, Smart Workflow
The Max4 is a "smart" factory in a box. The integrated AI Camera monitors your prints in real-time, automatically pausing if it detects a failure. Combined with full-auto calibration and 3-in-1 air filtration (HEPA + Carbon), it provides a professional environment that is safe and reliable.
-
Polar Cooler (Optional): Active toolhead cooling system that prevents heat creep and clogs during high-speed printing.
-
Industrial Linear Rails: High-hardness guide rails ensure the motion system remains smooth over thousands of hours of use.
-
QIDI BOX Integration: Ready for multi-color and multi-material projects, including soluble supports.
