Bambu's largest bed-slinger build volume, big enough to print full-size helmets and large props in a single piece rather than in glued sections.
The A2L stores several calibration sets at different heights up the Z axis to keep the faint vertical banding of tall bed-slinger prints under control.
An add-on blade-cutting and pen module extends the A2L beyond printing for sticker cutting and plotting workflows.
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.
