Researchers discover that every 3D printer leaves a unique "fingerprint" on prints, and they can be tracked back pretty accurately
It turns out that every printer can be identified by its prints, even between machines of the same make, resin, and settings.
If someone 3D printed an object and handed it to you, how confident would you be in your ability to tell exactly what model of 3D printer made it? I don't know about you, but I would have zero chance at identifying what machine made it without random guessing.
