Blank OpenPrintTag (10 NFC Tags)

This pack of 10 blank, writable OpenPrintTags is for advanced makers and builders who want to start experimenting with the new open standard right away. These tags are for integrating into custom printer builds (like Voron), mobile apps, developing your own filament management tools, or adding your existing spools to a smart inventory. These are blank tags that require user setup and are not a simple plug-and-play solution at this time. 

Includes: Blank OpenPrintTag NFC tag (10 pcs)

 Important 
The OpenPrintTag glued to a spool resists up to 80 °C when drying.

About OpenPrintTag

The OpenPrintTag standard is an open-source initiative by Prusa Research, creating a single smart spool standard that works across all brands and ecosystems. It is free to use, free to extend, and open for anyone to build upon. Most importantly, it works entirely offline. All essential data is stored directly on the tag. Your printer can recognize the spool instantly, with no dependence on cloud services or vendor lock-ins.

Offline by design: The OpenPrintTag is writable. It’s not just a tag that holds an ID; you can write important data directly to it. All essential data – material, color, key print settings, and remaining filament – is stored on the tag. Your printer doesn’t need Wi-Fi or a cloud service to identify the spool.

Fully open-source: OpenPrintTag is a published standard that is completely free to use, free to extend, and works across brands. Anyone can build on it without any licensing fees. This is critical for making it the one standard that everyone can adopt.

Reusable and rewritable: This is what a smart spool was always meant to be. Your printer or a mobile app can write the exact remaining filament length back to the tag after every print. No more guesswork. When a spool is empty, peel the tag off, stick it on any filament you own, and flash it with your phone. Instantly, your old spool is smart. No vendor lock-in, no waste.

Smarter hardware & readability: The hardware itself is clever. The tag is a large circle, which means it can be read and written to in any orientation. You don’t have to wait for the spool to spin to a specific position. It’s powerful enough to be read through an entire 2kg (Prusament) spool, so one tag is all you need – no more complex systems with a tag on each side. The data is always in sync.

Universal compatibility:The OpenPrintTag standard works across all brands and ecosystems. This universal standard guarantees compatibility on all supported devices, eliminating proprietary walled gardens. Designed to be used with filament spools, resin containers, and other applications.
