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 →Overdue for a refresh — no successor announced yet. Prices should be at their lowest
Best for: Budget makers who want 4-color multicolor printing without committing to the Bambu or Prusa ecosystem — and are comfortable with a less mature software experience.

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 V2 expands to 255×255×260 mm — 34% more printable volume than the original Kobra 3 — for larger parts and more batch production.
The V2 includes a 720p camera for real-time print monitoring and AI spaghetti detection, adding reliability features previously absent from the Kobra 3 line.
The Kobra 3 V2 Combo with ACE Pro is one of the most affordable 4-color setups available — often underpricing Bambu's A1 Combo.
