Automatic setup and preheat
Insert the filament and the printer reads the material and color from the tag, then starts heating to the target temperature. No more printing with the wrong filament!
Remaining material tracking
When the print is done, the printer writes the remaining material amount back to the tag. You always know how much is left on the spool before starting your next print.
Easy to install
Remove the spool holder, mount the reader, plug the cable into the xBuddy board and screw the holder back on. Clear step-by-step instructions guide you through the job.

New spools with OpenPrintTag
Smarter spools. Open standard. No cloud lock-in.
Starting October 2025, all Prusament filaments ship on a redesigned spool with a fully rewritable NFC tag powered by the OpenPrintTag standard.
The OpenPrintTag attached to your Prusament spool contains essential data about the material and can be read with the Prusa mobile app. It works entirely offline, it is free to extend, and open for anyone to build upon.
