The Anycubic Kobra S1 (prosumer) and Prusa Research XL+ (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 CoreXY printers with automatic calibration. The XL+ costs $1,800 more and gets you 199% more build volume and extra engineering materials (PA-CF and PC); the Kobra S1 answers with an enclosed chamber 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.

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 XL+ was released on Aug 13, 2026, 91 days ago. Prusa Research has already announced what comes next: XL Pick & Place Toolhead (Late 2026). Because Prusa Research sells upgrade kits for this line, owners can move up without replacing the whole printer.
Neither is a clear buy-now on timing, so watch for announcements before committing.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Kobra S1 lists at $499 and the XL+ at $2,299 — $1,800 apart, so the XL+ costs 361% more.
Per litre of build volume, that works out to $32 for the Kobra S1 versus $49 for the XL+ — 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 XL+, for 199% more build volume and extra engineering materials (PA-CF and PC), plus a higher editor score (8.7 vs 8.3). Go for the Kobra S1 instead if you want to spend less — it is $1,800 cheaper ($499 vs $2,299).
How we judge timing and deals: read our methodology →
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.
Unlike filament-switching AMS/MMU systems, the XL physically swaps print heads. Each material has its own nozzle, eliminating purge towers entirely and enabling true multi-material prints.
One of the largest build volumes available in a CoreXY printer at this price point — suited for large props, architectural models, and batch production.
Every component is documented, parts are stocked for years, and the community has developed hundreds of modifications and improvements.
