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.
At $279–299 with ACE Gen 2 included, the Kobra X is one of the most affordable ways to get into multicolor FDM printing.
A slightly larger cube-format build volume than the Kobra 3 V2's 255×255×260 mm bed — practical for most everyday prints.
The second-generation ACE Gen 2 offers improved filament switching reliability over the original ACE Pro, with support for up to 4 colors per print.
