First-generation product — no release history to base predictions on
Best for: Makers who want an enclosed CoreXY at a prosumer price for PLA, PETG, ABS, and ASA — and prefer the Anycubic ecosystem. For reliable PA or PC printing, consider the Kobra S1 Max or Qidi Q2 which offer active chamber heating.

The Kobra S1 combines an enclosed build chamber with 600 mm/s CoreXY motion — offering improved heat retention over open-frame printers for ABS and ASA.
Brings Anycubic's value-focused approach to the enclosed CoreXY segment — competing with Qidi Q2C and Bambu P2S at a lower price point.
A practical cubic build volume well-suited for functional mechanical parts, enclosures, and prototypes.
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.
