Yeah you can see the slop in the prints when the axis stops. You can just change print settings and it won’t look the same between prints. You can also use chemicals to smooth the outside of the print.
Comment on 3D Printing Patterns Might Make Ghost Guns More Traceable Than We Thought
IAmNorRealTakeYourMeds@lemmy.world 5 weeks agoI think there was a study that showed every 3d printer leaves a sort of fingerprint, and they can identify which printer printed what object.

In a lab, probably. In reality? No. Print nozzles wear over time time and their patterns will change accordingly, and they are entirely replaced often.
