Frankly it seems more like a mild inconvenience then actual prevention. I don’t really care how smart a software gets, it can’t predict and prevent all possible configurations of prints that could possibly be used to create functioning guns without being so overly restrictive that even perfectly innocent prints would get flagged constantly in which case they simple won’t sell too normal users.

It would be a constant game of whack a mole with new creative designs, using multiple printers or with non-printed parts in the design. But no hardware or software that a smart enough engineer has their hands on its impervious to mods either, especially if they’re motivated like someone seeking to produce firearms would be.

It’s an overreaching law that will likely solve little to nothing, but might make 3d printers in general a bit more annoying to work with. “Sorry, you can’t make your dice tower because they’re a 16 percent change that it could be capable of firing an RPG out of the dragon’s mouth. Please make your design at least 12 percent less gun-ish and try again.”
