I think my issue is practicality in testing. They have to have the print, and the printer. To test they likely need the file, modified with the same slicer settings as set originally. There are just so many factors, I have a hard time seeing them get all the required pieces, get them all in working order (especially the printer), then have the means to print the same thing in the same way. After all of that, now they have to measure some patterns and prove they’re the same across prints.

I feel like the complexity of the problem introduces more chances for false positives, or just enough of a shift in how the printer is tuned, how the file is set up, etc to make the process unreliable at best.

I guess we’ll see, but idk. A poor tool still has potential for abuse even if it doesn’t work as originally intended.
