The CORE One+ (prosumer) and CORE One L+ (professional) are a step-up decision within Prusa Research's lineup: same ecosystem, different class of machine. Both are enclosed CoreXY printers with automatic calibration. The CORE One L+ costs $1,000 more and gets you 100% more build volume and extra engineering materials (PA-CF); the CORE One+ answers with 8-slot multicolor and a top speed of 600 mm/s (vs 500).
Early in release cycle — no urgency to wait
🔧 Upgrade kit available — from CORE One+, MK4S
Best for: Makers who want CoreXY speed and precision with Prusa's open-source ethos, community support, and long-term repairability — without Bambu's closed ecosystem.

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 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 CORE One+ has roughly 118 days of runway on past cadence 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 CORE One+ lists at $999 and the CORE One L+ at $1,999 — $1,000 apart, so the CORE One L+ costs 100% more.
Per litre of build volume, that works out to $67 for the CORE One+ versus $67 for the CORE One L+ — the CORE One+ is the better value per litre as well.
Our pick for most buyers is the CORE One+, for a lower price ($1,000 less) and 8-slot multicolor, plus a higher editor score (9.0 vs 8.6). Go for the CORE One L+ instead if you print large parts — its 300 × 300 × 330 mm build volume holds 100% 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.
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.
