The Anycubic Kobra S1 (prosumer) and Prusa Research CORE One L+ (professional) come from different brands and sit in different tiers, so this is less a head-to-head than a question of how much printer you need. Both are enclosed CoreXY printers with automatic calibration. The CORE One L+ costs $1,500 more and gets you 90% more build volume and extra engineering materials (PA-CF and PC); the Kobra S1 answers with 4-slot multicolor and a top speed of 600 mm/s (vs 500).
First-generation product — no release history to base predictions on
Best for: Makers who want an enclosed multicolor 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.

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 was released on Feb 11, 2025, 639 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.
On timing alone, the CORE One L+ is the safer buy right now — it is only 33% of the way through its expected cycle, while the Kobra S1 has no release history pointing to a successor yet.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Kobra S1 lists at $499 and the CORE One L+ at $1,999 — $1,500 apart, so the CORE One L+ costs 301% more.
Per litre of build volume, that works out to $32 for the Kobra S1 versus $67 for the CORE One L+ — the Kobra S1 is the better value per litre as well.
If you are buying before Dec 5, 2026, the active sale tips value toward the Kobra S1.
Our pick for most buyers is the CORE One L+, for 90% more build volume and extra engineering materials (PA-CF and PC), plus a higher editor score (8.6 vs 8.3) and better buy-now timing. Go for the Kobra S1 instead if you want to spend less — it is $1,500 cheaper ($499 vs $1,999).

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 the Qidi Q2 and Bambu P2S, with multicolor and filament drying included at $499.
A practical cubic build volume well-suited for functional mechanical parts, enclosures, and prototypes.
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.
