Prusa Refreshes XL, CORE One Lineup With New Plus Models

Prusa Research quietly shipped the biggest hardware refresh its lineup has seen in years. The Czech manufacturer revamped three machines: the CORE One+ (Gen 2), the CORE One L+, and the XL+. All three ship at the same prices as their predecessors, and existing owners can buy upgrade kits instead of replacing everything.

The changes are incremental on paper but meaningful in practice. A new nozzle wiper cleans the tip between layers, a small detail that saves time and improves surface quality. GT1.5 belts replace the old ones, reducing moire patterns and resonance artifacts that show up on large prints. The XL+ gets a 360-degree cooling shroud that surrounds the nozzle with more controlled airflow, which helps with overhangs and small details.

Prusa also raised the chamber temperature ceiling to 60 °C on the enclosed models. That matters for ABS and high-temperature engineering plastics. The combination of a heated chamber and better cooling gives these printers an edge for large functional parts, an area where Prusa already compares favorably to competitors.

For users who service their own machines, the new top panel on the CORE One+ (Gen 2) snaps off for easier access. The heatbed mounting system was revised to eliminate the initial heat-soak step for PLA and PETG, shaving minutes off startup time. A permanently mounted sensor makes toolhead calibration roughly 20 times faster, according to Prusa.

The biggest longer-term play is INDX automatic tool-changing coming to the CORE One+. Prusa also tweaked Pressure Advance to account for melt flow index and wall slip, meaning extrusion should stay more consistent when switching between filament brands or batches.

Upgrade kits are rolling out now, starting with the CORE One+. The CORE One L+ and XL+ kits arrive around the end of August. Open orders for the older models will automatically ship as the refreshed versions.

This refresh signals where Prusa sees its advantage. The company is not chasing the budget market with flashy new features. It is targeting users who plan to keep a printer for years, who value spare parts, and who want a machine that improves over time. That is a sensible response to price pressure from cheaper alternatives.
