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.
The Q2 actively heats the print chamber — not just passively traps heat. This is the key differentiator for reliable ABS, ASA, PA-CF, and PC printing without warping.
Triple-stage filtration removes 99.5% of particulates and VOCs — essential for printing ABS and ASA in a home or office environment.
Handles the full spectrum of engineering filaments including carbon and glass fiber composites without a hotend upgrade.
