The A1 Mini sets up in minutes with automatic calibration and Bambu's guided first-print workflow.
Up to 4 colors with the AMS Lite accessory — Bambu's filament switching system with minimal waste purging.
Fits on a desk or shelf without taking over your workspace, while still printing at 500 mm/s.
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.
