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 H2C's Vortek system swaps hotends wirelessly — no filament purging, no switching waste. Each material has its own dedicated nozzle, enabling true multi-material production including soluble support combinations.
With up to 6 active hotends and the Vortek architecture, the H2C supports 7 simultaneous material slots — the highest material count in Bambu's lineup.
At $2,399, the H2C is positioned above the H2S as Bambu's flagship professional tool-changer — targeting studios and engineers who outgrow filament-switching AMS multicolor.
