First-generation product — recently released, still early days
Best for: Professional makers and small studios who need the maximum enclosed build volume in Qidi's lineup for large engineering parts, architectural models, or batch production — at a price point below the Bambu H2S.
Full details →Early in release cycle — no urgency to wait
Best for: Serious makers and prosumers who need enclosed printing for ABS, ASA, PA, PA-CF, and PC — and want Bambu's plug-and-play experience at a prosumer price.

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 P2S enclosure maintains a more consistent chamber temperature over the P1S, reducing warping on long ABS and PA prints.
PLA through PC — the P2S handles the entire engineering filament spectrum with reliable results.
The P-series CoreXY enclosure design strikes the best balance of price, speed, and material capability in Bambu's lineup.
