Some good discussion from /c/3dprinting@lemmy.world about how it really isn’t as dependable/tracable as the article says:
https://lemmy.world/post/33199760
TLDR is 3D printing typically uses brass nozzles which wear down over time which will change marks left over time, your bed leveling can change over time, and the “fingerprints” the article talks about can be avoided by just printing in different positions/rotations on the bed.
Show me 20 people with 3D printers and I'll show you 20 people with a bunch of spare nozzles on hand.
