The Anycubic Kobra S1 Max and Prusa Research CORE One L+ are both professional-tier printers, but the CORE One L+ costs 2.5× as much — so the question is what the extra money buys. Both are enclosed CoreXY printers with automatic calibration. The CORE One L+ costs $1,200 more and gets you an open-source design; the Kobra S1 Max answers with 4-slot multicolor and 44% more build volume.
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.

Best for: Engineers and professional makers who need large-format enclosed printing with active chamber heating — and want Prusa's open-source ethos and long-term support over a closed-ecosystem competitor.

The Kobra S1 Max was released on Nov 25, 2025, 352 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
The CORE One L+ was released on Aug 13, 2026, 91 days ago. Its previous release cycle ran about 279 days, so it is 33% of the way through — roughly 188 days before a successor would be due at that pace.
Both are early enough in their cycles that timing should not decide this one. The Kobra S1 Max launched 352 days ago and the CORE One L+ has roughly 188 days of runway on past cadence. Pick on features and price.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Kobra S1 Max lists at $799 and the CORE One L+ at $1,999 — $1,200 apart, so the CORE One L+ costs 150% more.
Per litre of build volume, that works out to $19 for the Kobra S1 Max versus $67 for the CORE One L+ — the Kobra S1 Max is both cheaper and roomier, so it wins on value outright.
If you are buying before Dec 5, 2026, the active sale tips value toward the Kobra S1 Max.
Our pick for most buyers is the Kobra S1 Max, for a lower price ($1,200 less) and 4-slot multicolor. Go for the CORE One L+ instead if you want an open-source printer you can modify and repair yourself — the Kobra S1 Max is not open source. The Kobra S1 Max is also in a sale window right now (Black Friday 2026, until Dec 5, 2026).
How we judge timing and deals: read our methodology →
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.
A large enclosed build volume with genuine active chamber heating — making the CORE One L+ reliable for ABS, ASA, PA, and PC across the full build plate.
All firmware, hardware designs, and slicing profiles are open source. Prusa backs the CORE One L+ with long-term parts availability and community support.
For institutional, government, and production customers, a dedicated Critical Infrastructure Edition is offered — Prusa's commitment to secure supply for professional users.
