First-generation product — recently released, still early days
Best for: Professional makers and small studios who need large-format enclosed printing for engineering filaments at a competitive price — and want Anycubic's ecosystem over Creality or Qidi alternatives.
Full details →Overdue for a refresh — no successor announced yet. Prices should be at their lowest
Best for: Makers and small businesses who need a large enclosed build volume for engineering materials at a prosumer price — particularly those printing PA-CF, ABS, and PC at scale.

One of the largest enclosed build volumes in the prosumer/professional tier — suited for large engineering parts, architectural models, and batch production.
Maintaining 65°C across a 350×350 mm chamber is a meaningful technical achievement — ensuring consistent results for ABS, ASA, and PA across the full build plate.
The S1 Max extends the Kobra ecosystem into the large-format enclosed segment, enabling Anycubic users to scale up without switching brands.
One of the largest build volumes in the prosumer enclosed category — 40% more printable area than the Bambu X1C at a lower price point.
The second-generation active heating delivers consistent chamber temperatures for PA, PA-CF, ABS, ASA, and PC with minimal warping across the full build plate.
Handles high-performance engineering composites including PA-CF, PET-CF, and PPS-CF without requiring a separate hotend upgrade.
