Early in release cycle — no urgency to wait

An official upgrade kit is available for CORE One+, MK4S owners — letting you reach CORE One+ specs without buying a whole new printer. This is unique to Prusa and changes the buying calculus significantly.

Key strengths
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.
The Prusa CORE One+ (Gen 2), released August 13, 2026, is the second hardware revision of Prusa's enclosed CoreXY printer. It adds a redesigned heatbed mounting that removes the heat-soak wait for materials printed at bed temperatures up to 85°C, GT1.5 belts for smoother surfaces, an integrated nozzle wiper, a tool-free snap-on top panel, and a sturdier automatic top vent. Build volume is unchanged. CORE One+ owners can upgrade with a low-cost kit, and MK4S owners can convert with a conversion kit. It can also be ordered with Prusa's INDX toolchanger in 4- and 8-tool versions, which start shipping on 15 October 2026 and give each material its own nozzle for multi-material printing with almost no purge waste. Fully open-source from firmware to hardware designs, it remains Prusa's direct answer to Bambu's P-series.
The defining choice is ecosystem philosophy. Bambu offers a polished closed ecosystem with faster setup, proprietary cloud features, and an aggressive innovation cadence. Prusa offers open-source hardware, longer product lifecycles, community repairability, and no lock-in. If you plan to modify, repair, or build on the printer, Prusa. If you want the fastest out-of-box experience, Bambu.
The CORE One+ is a fully enclosed CoreXY with active chamber temperature control up to 55°C, so it handles ABS, ASA, and PA out of the box. The CORE One L+ (larger sibling with active 60°C chamber heating) is available for those needing an even larger heated chamber.
Yes — the kit is significantly cheaper than the assembled version and gives you deep familiarity with your printer's components, making maintenance and troubleshooting easier.
Yes. Prusa sells a CORE One+ to Gen 2 upgrade kit (GT1.5 belts and pulleys, Gen 2 expansion joints, nozzle wiper) and an MK4S to CORE One+ (Gen 2) conversion kit. The Gen 2 kit fits the CORE One+ only — an original CORE One has to be brought to CORE One+ spec first. See Prusa's upgrades page for current pricing and lead times.
INDX is Prusa's toolchanger for the CORE One family: each material has its own nozzle, so a material change takes about 12 seconds and leaves almost no purge waste. Prusa sells complete CORE One+ (Gen 2) INDX printers with 4 or 8 tools, assembled or as a kit, shipping from 15 October 2026; the 4-tool version has docking slots to expand to 8 tools later. The INDX build volume is slightly smaller at 248×205×270 mm. INDX conversion kits for the CORE One, CORE One+, and CORE One+ (Gen 2) are listed on Prusa's store as pre-orders, with the next batch also shipping from 15 October.
