Prusa Refreshes CORE One+, CORE One L+, and XL With Upgrade Kits

What changed

Prusa Research refreshed its high-end desktop 3D printer lineup on August 20, 2026. The CORE One+ (Gen 2), CORE One L+, and XL+ all get hardware upgrades, and existing owners can buy upgrade kits instead of replacing the whole machine.

The most visible addition is a nozzle wiper. It sits in front of the extruder and cleans the nozzle between layers or tool changes. Prusa had resisted wipe towers for years, so this is a real shift in approach. On the XL+, the wiper pairs with a new 360-degree cooling shroud that routes airflow around the nozzle for better detail and overhang performance.

A Tool Offset Sensor should speed up toolhead alignment by roughly 20 times, according to Prusa. New GT1.5 belts are meant to cut resonance and moire patterns. The top panel on the CORE One+ and CORE One L+ now lifts out more easily for maintenance, which matters if the printer sits on the floor.

Chamber heating

The enclosure now includes a chamber heater capable of reaching 60 degrees Celsius. That is not a headline number, but it makes ABS far more reliable. Higher chamber temps reduce warping and improve interlayer adhesion for large ABS parts. Prusa says the same heat also helps PETG, PC Blend, and PCCF prints. The company already had a reputation for handling large engineering plastics well, so this extends that lead.

Upgrade path and pricing

Prusa kept the price of the new printers unchanged. Upgrade kits are available online through September, and any existing order will automatically receive the new hardware. Backward compatibility is a selling point here. Industrial buyers care about asset life, and Prusa is leaning into that. Spare parts remain available, and many components can be printed or modified by the community.

Software and future plans

Prusa also teased INDX automatic tool-changing for the CORE One+ down the line. Pressure Advance was updated to react better to melt-flow-index differences and wall-slip effects across filament batches. PrusaSlicer 3.0 is arriving in a few weeks with workflow changes that should make the slicer feel faster.

A new HT Hotend upgrade for the CORE One and CORE One L+ ships in September.

The bigger picture

Prusa is clearly aiming at users who view a 3D printer as a machine tool, not a hobby gadget. Longevity, serviceability, and European manufacturing still matter in defense, medical, and education markets. That focus makes sense while budget competition from Bambu Lab intensifies at the consumer level.
