The CORE One+ (prosumer) and XL+ (professional) are a step-up decision within Prusa Research's lineup: same ecosystem, different class of machine. Both are CoreXY printers with automatic calibration. The XL+ costs $1,300 more and gets you 214% more build volume and extra engineering materials (PA-CF); the CORE One+ answers with an enclosed chamber and a top speed of 600 mm/s (vs 500).

The CORE One+ was released on Aug 13, 2026, 91 days ago. Its previous release cycle ran about 209 days, so it is 44% of the way through — roughly 118 days before a successor would be due at that pace.
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.
On timing alone, the CORE One+ is the safer buy right now — it is only 44% of the way through its expected cycle, while the XL+ has its next step announced (XL Pick & Place Toolhead, Late 2026), with upgrade kits for existing owners.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The CORE One+ lists at $999 and the XL+ at $2,299 — $1,300 apart, so the XL+ costs 130% more.
Per litre of build volume, that works out to $67 for the CORE One+ versus $49 for the XL+ — so the pricier XL+ actually gives you more build space per dollar.
Our pick for most buyers is the CORE One+, for a lower price ($1,300 less) and an enclosed chamber, plus a higher editor score (9.0 vs 8.7) and better buy-now timing. Go for the XL+ instead if you print large parts — its 360 × 360 × 360 mm build volume holds 214% more than the CORE One+'s 250 × 220 × 270 mm.
How we judge timing and deals: read our methodology →
The CORE One+ matches Bambu CoreXY speed (600 mm/s) while keeping everything open source — firmware, hardware, slicing profiles.
Unlike Bambu's closed ecosystem, every component of the CORE One+ can be modified, repaired, or community-improved.
The CORE One+ (Gen 2) can be ordered with Prusa's INDX toolchanger in 4- or 8-tool versions, shipping from 15 October 2026. Each material gets its own nozzle, with about 12 seconds per material change and almost no purge waste. The MMU3 remains compatible as a 5-color add-on.
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.
