Prusa Research is upgrading its XL, Core One and Core One L printers to second-generation "+" versions, adding a nozzle wiper and finer belts across the range. Current sales units already ship with the changes and open orders are converted, with no price rise. Upgrade kits for existing owners are due on the webstore by September.
Key facts
XL, Core One and Core One L all get a nozzle wiper and GT1.5 belts
Upgrade kits and single parts reach the webstore by September
The optional HT Hotend for Core One reaches 400 °C
The MK4S gets no upgrade but stays supported
Context An eddy-current sensor measures position without contact, here used to align the toolheads of a multi-tool printer.
What changes on each printer?
All three machines get an integrated nozzle wiper, which Prusa describes as the most requested upgrade, and GT1.5 belts. The XL also gets the 360-degree cooling introduced on the MK4S and the Tool Offset Sensor from the INDX, an eddy-current sensor that is 20 times faster than pin tapping and stays mounted. New XL units ship with high-flow nozzles, and the optional enclosure gains heating of the chamber and better sealing.
The Core One+ also gets improved heatbed mounting and the snap-on top panel known from the Core One L.
What about existing owners and software?
The upgrades are fitted to printers sold today, and open orders are converted to the plus version. Prices stay unchanged. Kits and individual components will be sold separately on the webstore by September. The MK4S is not part of the programme, but Prusa says it keeps supporting it.
An optional HT Hotend for the Core One line arrives in September. It reaches 400 °C for materials such as PEKK-CF and PPS-CF. Prusa Slicer 3.0 is due in a few weeks, and Prusa Connect Local will replace PrusaLink for LAN connection.
What it means
For small and mid sized manufacturers running Prusa fleets for fixtures, jigs and low-volume parts, the main value is lower hands-on effort from a built-in wiper and faster toolhead alignment, not new capability. Unchanged prices and à la carte kits let owners upgrade selectively. The 400 °C hotend widens material options, but qualifying such materials for production remains the user's task. This follows the earlier coverage of the Core One L+ and the 400 °C hotend.
Do owners of current Prusa printers have to pay for the plus versions?
No. Printers sold now and open orders get the plus version at the same price. Existing owners can buy upgrade kits or single components on the webstore by September.
Is the MK4S included?
No, the MK4S is not part of the upgrade programme, but Prusa says it continues to support the machine.
