But… you’d need to do several test prints with the suspects 3D printer to get a matching profile right? It doesn’t seem practical but indeed every 3D printer has it’s own fingerprint.

You’d also have to use the same slicer settings, similar room conditions, make sure that you have the same filament roll (assuming it’s an FDM printer), make sure that nothing hardware wise was tweaked (eg. fixing belt tension), make sure nothing software wise was tweaked (it’s nuts how much difference temp can make), make sure nothing firmware wise was tweaked, and the nozzle cant have had too many prints between the suspicious one and now (or like half of a glow in the dark or carbon fiber filled pring).

It’s also nuts how much difference eccentric nuts can make.

Both the ones for adjustment, and the operator.
