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.
To understand why preservationists hunt for files, let’s look at three key scenes.
In 2025 and beyond, corporations are deleting history. The original Mortal Kombat movie is often shown in a "digitally remastered" version where the grain is scrubbed away, making the ninjas look like wax figures. Mortal Kombat 3 is often sold as part of a compilation with input lag.

The 1995 Mortal Kombat is not a perfect film. The CGI for Reptile and Scorpion’s spear looks dated by modern standards, and the ending sequel-baiting is a bit clunky.
