If they just check hashes is it possible to just slightly modify the gun, like add a mm to the trigger or something, to change the hash? I would imagine you’d need a more sophisticated detection algorithm to check if what you’re printing is a gun. And I imagine people who want to 3D print a gun could buy a model of 3D printer that doesn’t have those restrictions; I imagine there’d be a market for it with cryptocurrency. But at that point maybe you’re better off just buying a gun directly on the black market.
I mean, it’s really easy to build a 3d printer from scratch (I’ve done it before).
Also, fuzzy hashing is a thing, it doesn’t have to be a perfect match to get detected. But really this isn’t a big issue, since 3d printing firearms is legal in most of the US, and detection isn’t common.
The article is about the UK, where you’re not even allowed to carry pepper spray let alone 3D print a gun. And guns are at least heavily restricted in most countries so I assume that, even if 3D printers sold in the US don’t have gun detection, it might be in 3D printers sold outside the US.
