QIDI Tech Max4: The New Flagship for Large Format 3D Printing

Take your creations to the next level with the QIDI Max4, the ultimate CoreXY 3D printer that combines an impressive print volume with unprecedented speed. Designed for those who accept no compromises, the Max4 transforms your desktop into a true digital factory capable of handling technical materials and industrial-scale projects.

Why choose the QIDI Max4?

• Gigantic Print Volume: With a work area of 390 x 390 x 340 mm, you have 55% more space than the previous generation. Print helmets in a single piece, functional prototypes or complex models without having to divide them.
• Extreme Speed and Precision: Thanks to the CoreXY structure and industrial-grade linear guides, you reach a maximum speed of 800 mm/s with an acceleration of 30,000 mm/s². Less waiting time, more productivity.
• Professional Thermal Control: The actively heated chamber up to 65°C ensures perfect prints with difficult materials such as ABS, ASA and Nylon, eliminating the risk of warping.
• High Temperature Hotend (370°C): The Direct Drive extruder with hardened steel gears allows printing carbon or glass fiber loaded materials, in addition to classic PLA, PETG and TPU.
• Integrated Artificial Intelligence: The AI Camera 1080p monitors printing in real time, detects errors and allows you to create fantastic timelapses to share.
• Multi-Color Ecosystem: The Max4 is natively compatible with the QIDI BOX, allowing you to print up to 16 different colors or use soluble supports (accessory sold separately).
