1. so it's banned in NY. That just means everyone else carries on as per usual.
2. how do you ban printing guns? Are printers going to be required to have some kind of AI recognition system for what they're printing? Because even if a printer can ban a specific model, tweak it here, tweak it there, and you have yourself a new model.
3. and what even is the point when you (or a friend, or a stranger you've paid) can just walk into a walmart and buy a gun? Even if there is a purchase record with id attached - you've never heard of fake ids? It's like the old slogan - if you ban guns, only criminals will have them. It's law that weakens the lawful person and strengthens the criminal.
