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 at a consumer price — ideal for life-size props, large terrain tiles, and batch production.
Few printers offer multicolor at this scale. The ACE Pro system enables filament switching across the full 420×420 bed area.
Delivers large-format multicolor at a fraction of professional large-format printer costs.
