The Max4 offers the largest build volume in Qidi's lineup — enabling large functional parts, architectural models, and production batch runs that exceed Plus4 capacity.
The Max4's closed-loop XY adds positional feedback for improved accuracy at high speeds — a differentiating feature at this price tier that reduces dimensional errors on large prints.
Qidi's proven active chamber heating technology scaled to a 390×390 mm bed — critical for consistent ABS, ASA, PA-CF, and PPS-CF results across the full build plate.
One of the largest build volumes available in an enclosed CoreXY printer, suited for large props, architectural models, and batch production.
Creality's CFS (Creative Filament System) provides 4-color filament switching comparable to Bambu's AMS at a lower price point.
The K2 Plus delivers professional-level features at a price point accessible to serious hobbyists and small studios.
