There were hundreds of mass shootings in America in 2025 alone [1]. None of them involved a 3D-printed weapon.
To my knowledge, there has been one confirmed shooting with a 3D-printed gun, and it didn't uniquely enable the crime.

That's mostly because they suck (for now, who knows when we'll get home metal printing), also it's easy to get real guns. also crises of accessibility could be predicate on merely the perception that the barrier is now too low rather than actual harm.
I don't really think photoshop, flat bed scanners and half decent inkjets really facilitated a lot of counterfeit currency but there was the same panic back then and "protections" put in place.
