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 massive build volume with unprecedented speed. Designed for those who accept no compromise, the Max4 transforms your desktop into a true digital factory capable of handling technical materials and industrial-scale projects.

Why choose the QIDI Max4?

• Massive Build Volume: With a 390 x 390 x 340 mm build area, you have 55% more space than the previous generation. Print one-piece helmets, functional prototypes, or complex models without having to split them.
• Extreme Speed ​​and Precision: Thanks to the CoreXY structure and industrial-grade linear guides, 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 you to print carbon or glass fiber filled materials, in addition to classic PLA, PETG and TPU.
• Built-in Artificial Intelligence: The 1080p AI Camera monitors your print in real time, detects errors, and lets you create stunning 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 media (accessory sold separately).
