Wow! Now that's some outside the box thinking. That even seems to suggest that "watermarking" a print (or a small, hard to notice part of a print) would be possible.

I also think you could get denser storage that way? I guess depending upon how thick the "wire" is? But it's an interesting idea for both just printing the wire, and for the driver-teeth imprinting, separately. Very cool!

Not sure how it will survive extrusion. But yeah, the wire is a cylinder so you can ‘imprint’ multple ‘sides’. Another idea, some form of anti temper encryption like little particles (flock) inside the filament (like those colored rice anti temper methods)
