Active chamber temperature control enables reliable ABS, ASA, PA, and PC printing without warping.
500 mm/s print speed with Bambu's vibration compensation delivers fast, accurate prints.
With the P2S released, P1S prices are at their lowest — an opportunity for budget-conscious buyers.
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.
