The Anycubic Kobra S1 Max, released November 2025, is Anycubic's large-format enclosed CoreXY with a 350×350×350 mm build volume and 65°C active chamber heating. It brings Anycubic's value-focused approach to the large enclosed engineering printer segment, competing with the Creality K2 Plus and Qidi Plus4.
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.
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.
Both offer large enclosed build volumes with chamber heating at similar prices. The Creality K2 Plus has a more established community and longer track record in the large-format segment. The Kobra S1 Max is newer with Anycubic's ecosystem and 65°C active heating. Evaluate based on regional pricing and your existing ecosystem preference.
The Qidi Plus4 ($699) has a 305×305×280 mm build volume with active 65°C chamber heating and HEPA filtration. The Kobra S1 Max offers more build volume (350×350×350 mm) at a potentially similar price. For maximum build area, the S1 Max. For the best-rounded engineering printer value at this tier, the Plus4's HEPA filtration and proven Klipper-based platform give it an edge.
The 65°C chamber heating significantly improves PA-CF results over open-frame printers. Ensure you use a hardened steel nozzle for carbon-fiber filaments and thoroughly dry your filament before printing. Results will be best for smaller-to-medium parts — very large PA-CF prints across the full 350×350 mm plate will require careful calibration.
