QIDI Max4
The QIDI Max4 is a large-format enclosed CoreXY printer that QIDI Technology unveiled at Formnext 2025 (shipping from 2026). It has a 390×390×340 mm build volume, a 370 °C nozzle, a 120 °C bed and an actively heated chamber up to 65 °C; it weighs 40 kg and starts at $1,099. It is built for large functional parts in engineering materials, printed in one piece.
Owners most often discuss the noise with the external Polar Cooler (62 dB vs 56 dB normally), cumulative dimensional error on big parts, the rough mobile app and firmware at launch, and printing ABS, ASA, nylon and carbon-fiber composites in the hot chamber.
This section collects reviews, comparisons and guides for the Max4. See also the QIDI Max4 spec card, the smaller QIDI Plus4, and our guide to safety and ventilation when printing engineering materials.
