Prusa Upgrades Its Entire Lineup With Plus-Series Printers

Prusa Research has refreshed its entire 3D printer lineup with Plus-series upgrades that improve print quality and usability without raising prices. The new models are the Core One+ (Gen 2), Core One L+, and XL+. Existing orders that have not shipped yet will receive the updated versions for free.

The biggest change across all three machines is the switch to GT1.5 belts. Prusa says the new belts make fine-line artifacts on smooth surfaces much less noticeable. That translates into cleaner part finishes, especially on top layers and curved surfaces where belt patterns tend to show through.

Every Plus-series printer now includes an integrated nozzle wiper. This has been the most requested community modification, and Prusa building it into the machine means users no longer need to tweak g-code or install third-party solutions. The wipe happens automatically before each print starts.

The Core One+ (Gen 2) receives the broadest set of changes. It gets the nozzle wiper, GT1.5 belts, and a redesigned heatbed mounting system that removes the warm-up delay at the start of PLA and PETG prints. A new snap-on top panel makes maintenance easier. Owners of the original Core One can buy a complete upgrade kit.

The Core One L+ is the smallest refresh. Since the standard Core One L already incorporated many of the Core One+ design improvements, the L+ mainly adds the GT1.5 belts and nozzle wiper. Prusa is selling the L+ upgrade kit for GBP 22.99, making it the cheapest entry point into the Plus ecosystem.

The XL+ gets the most dramatic upgrade. It gains a 360-degree cooling system borrowed from the MK4S and CORE One series, which improves overhangs, bridges, and small details. The toolhead calibration system is now 20 times faster thanks to a permanently mounted eddy-current sensor that replaces the old removable pin method. High-flow nozzles are standard, and the enclosure is better sealed with optional chamber heating to reach 60 degrees Celsius.

Prusa is not increasing prices. The company is also committing to longer software support than most competitors. PrusaSlicer 3.0 is coming soon, and firmware updates will continue for existing machines. For owners who want to upgrade piece by piece, individual parts and complete kits will be available through Prusa's webstore starting in September.

The message is clear: Prusa wants these machines to get better with age. In an industry where many brands abandon older models after a few years, that commitment to existing owners stands out.
