Taking this purely as an engineering task, how is this remotely possible? I can barely begin to imagine how restrictions on what can be printed could be set. Am I missing something obvious? Some kind of contextual understanding of the object seems to be necessary... please don't tell me their proposed solution is AI.

In any case it will never work because 3D printing is so easy for makers to do from scratch, so any solution will fail to prevent printed guns from being made.

Again, this is just the pragmatic engineering angle. Please don't respond with political arguments.

I don't know the answer to the question, but paper printers cannot print bank notes apparently

Most currencies have a special pattern that printers are programmed to detect and refuse to print. Since illegal gun part designs can't be forced to include a marker declaring that they're gun parts, a 3d printer would have to 1) know what a gun is, 2) know how a gun works, 3) be able to tell whether any particular shape could be used as part of a gun, and 4) be able to tell whether any particular shape could be cut and reassembled into a shape that could be used as part of a gun
