Qidi Max4: The Flagship Industrial-Grade Large-Format 3D Printer
Break the size barrier with the Qidi Max4, the ultimate powerhouse in the Qidi lineup. Engineered for those who need 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 isn't just a "larger" printer; it's a completely redesigned flagship featuring Closed-Loop Motors and a Polar Cooler (optional accessory)Â 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, you can print large functional parts in a single piece, reducing the need for assembly and increasing part strength.
-
FOC Closed-Loop Stepper Motors: Experience industrial-level precision.
-
Active Chamber Heating (Up to 65°C): Essential for engineering materials like ABS-CF, PC, and Nylon, the second-generation heated chamber prevents warping and ensures 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 your filament keeps up with the motion system.
-
Ultra-Stable Z-Axis: Featuring large lead screws and an anti-backlash nut, the Max4 delivers a flagship-level surface finish with zero Z-wobble, even on tall, heavy models.
Technical Specifications
Industrial Performance, Smart Workflow
The Max4 is a "smart" factory in a box. The integrated AI Camera uses a high-performance processor to monitor 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, reliable, and incredibly easy to use.
- Polar Cooler: An active toolhead cooling system that prevents heat creep and clogs during high-speed printing (optional accessory)
- Industrial Linear Rails: High-hardness guide rails ensure the motion system remains smooth and accurate over thousands of hours of use.
-
QIDI BOX Integration: Ready for multi-color and multi-material projects, allowing for soluble supports or complex aesthetic designs.
Who Is the Max4 For?
-
Manufacturing Labs: For large-scale end-use parts and jigs.
-
Automotive/Aerospace: For high-temperature, high-strength functional prototyping.
-
Power Users: Makers who need the maximum possible build volume without compromising on speed or material capabilities.
