Applicability is in the eye of the beholder… of bureaucracy.

It is not really enforceable what people grow in their nook with led lights, or what they produce with metal lathes and metalworking tools, or what they mix up with common chemicals, and yet!

With EURion, printers/scanners that are capable of somewhat convincing replica go into the “definitely need to do this thing” money bracket I guess.

Printer instructions are also usually quite convoluted (don’t event know if anybody really knows the actual format), but definitely it’s not the actual document being sent to a printer (except last decade printers), just the actual dithered inkjet patterns, though I am heavily guesstimating. And yet, from inkjet patterns, the printer knows to crash, presumably, though I dont know, the knowledge of currency steganography seems spotty…

There is a semi-infinite amount of processing that can be done on the slicing machine, so detecting gun-like item is wildly possible. Making your own slicer is the same as making your own photoshop (or hacking it). I definitely don’t see 3d printers having enough horses to figure out a non-watermarked-model produced geocode to have gunlike things. But! We forget! With legislation, everything is possible. Probably will require any decent (especially things like metal) 3d printer to have an ISIC specifically programmed to rebuild a model from geocode and do analysis :D (Honestly, completely easy with current technology, MNIST 99.99% accuracy fits into 10k transistors or so)
