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 →This printer is no longer sold new. It has been replaced by the Bambu Lab H2S.
Best for: Professional makers seeking the X1C should now consider the H2S (current flagship) or P2S (prosumer enclosed). Clearance X1C units offer the LiDAR and AI monitoring features at a reduced 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 X1C's LiDAR sensor maps bed surface deviation and adjusts in real time — the most reliable first-layer consistency in its class.
The built-in camera with spaghetti detection pauses prints automatically when failures are detected — critical for unattended production runs.
The X1C uses a die-cast metal frame and carbon-fiber-reinforced structure for rigidity at high speeds.
