Prusa Research upgrades entire 3D printer lineup to «+» — existing orders get it free of charge

Prusa Research has announced second-generation upgrades across its entire lineup of 3D printers. The XL, Core One, and Core One L models will all receive a «+» designation along with a set of improvements, and the company says buyers of new units will get the updated version automatically.

The key point for customers: orders that are already in progress will be fulfilled with the «+» hardware at no extra cost. Prusa Research also confirmed it is not raising prices on any machine receiving the upgrade. Those who already own one of the affected printers will be able to buy upgrade kits, either as a full set or as individual components purchased à la carte. The company plans to make all kits available on its webstore by September.

The bedslinging MK4S was notably left off the list. But Prusa Research stressed that this does not mean the end of support for the machine — the company continues to service every printer it has ever made, for years after release. Mikolau Zuza, Head of Content at Prusa Research, explained the philosophy in a blog post: the company does not expect users to replace a working machine just because something new arrives. While most tech becomes obsolete over time, Prusa printers keep getting better.

All three upgraded models will feature a new nozzle, a component that directly affects print quality. Further technical details about the improvements are expected to be revealed by the company in the coming weeks. The move positions the «+» versions as a free generational bump for anyone ordering now, rather than a paid refresh — a rare approach in the hardware market, where incremental updates usually come with a price increase or require a full replacement purchase.

For existing owners, the à la carte option means they can pick only the parts they actually need, avoiding the cost of a full kit. This flexibility, combined with the promise of long-term support, reinforces Prusa Research's reputation for keeping older hardware viable. The September deadline for webstore availability gives both new and existing customers a clear timeline for when the upgrades will be widely accessible.
