Ending the Wild West of Smart Spools
An open-source initiative by Prusa Research creating a single smart spool standard that works across all brands and ecosystems. This allows printers and users to read and write data directly on any spool, making 3D printing more reliable and intuitive for everyone.
3D printers have become incredibly user-friendly, but interaction with filament is still a very manual process. To improve the user experience and streamline the workflow, we need smart spools.
A smart spool carries all the important information about the material and its workflow, unlocking key features:
Instantly identifies the material type and color, significantly reducing user error and leading to a simpler, more reliable workflow.
Real-time data tracking, such as the amount of remaining filament, so you always know the exact status of your material.
Enables effortless inventory management and full traceability by allowing you to log custom data.
Some smart spools already exist, but they lack the core principles of universality and interoperability. It's like every brand suddenly decided to use a different filament diameter.
Smart spools are often locked to their specific hardware and filament. This makes them unusable with any third-party machines, forcing users into a closed ecosystem.
Many smart spools just refer to an online database, forcing you to rely on the manufacturer's cloud service. No internet? Your "smart" spool becomes dumb.
Current Smart Spools offer little to zero reusability. This read-only design prevents any updates to live data, and once the filament is depleted, you have no choice but to throw the 'smart' spool away.

The Xperia T2 Ultra, a phablet released by Sony in 2014, was a powerhouse of a device in its time. With its large 6-inch display, powerful Qualcomm Snapdragon 400 processor, and impressive 13-megapixel camera, it was a favorite among Android enthusiasts. However, as with any older device, it can be challenging to keep up with the latest software and security updates. This is where custom ROMs come into play.
Before attempting to flash a custom ROM, you must ensure your device is ready:
. By stripping away the heavy background processes inherent in manufacturer skins, custom ROMs like CyanogenMod (later LineageOS) or P.A.C-MAN ROM offered a "cleaner" and "snappier" user experience. These community-driven projects frequently brought newer versions of Android to the T2 Ultra long after official updates ceased, providing access to modern features and critical security patches. The Technical Challenges
Instantly read or write in any orientation. This eliminates the need to rotate the spool to find the "correct" position.
Stick a blank tag on any filament spool you own, flash it using your printer or a phone app, and simply re-use it once the spool is empty.
A single tag works even for 2kg spools, ensuring live data is always perfectly in sync. Two-tag designs cannot guarantee this.
A 3D printer or any compatible device instantly reads all data the moment the spool is loaded.
