At least in Australia all this is illegal now. You can't make firearms parts without an armourer's license... Maybe our overregulation will save us.
This is the valid way to go I think. You cant make a weapon of a certain type without a license. Get caught, go to jail.
The printing thing is just a kneejerk: "omg you can make the guns cause of this new fangled machine... from 1986". You could always make guns off the radar. Yes, printing an unregistered weapon is certainly easier today than it was yesterday, but I don't really think the rules change here. Punish the people who commit the crimes, not everyone who doesn't.
This is also different from a lot of other dubious new efforts to control internet consumption for example. Printers literally CAN'T be controlled any more than a soup spoon. You can certainly harass buyers of brand new consumer printers, but that wont have any impact on making weapons.
As it relates to us CNC people, here is how the dual use laws have played out - a far more serious set of laws. I cannot buy a VFD over 599hz because all the manufacturers have applied the law to their products due to the dual use export restrictions.... In canada. So I bought my VFD from vietnam. Yup... real good law there. Literally does nothing. zero, nada except annoy people that want high speed CNC spindles. I get the reason for the law too, and I even agree with the principle... but the implementation is utterly useless. You still need to track all your illegally exported goods the exact same way as before. You gained nothing you wanted from this law. (on a VFD, other items on the dual use list are more realistically managed)
