Thanks, according to that the only thing that had been printed were some “handgun frames”.

I don’t know why this of interest to HN other than it has the words “3D-printed” in it. Maybe we can talk about how somehow 3D printers make illegal manufacturing scarier?

I mean underground illegal weapon manufacturing has been a thing for hundreds of years, so there’s nothing new here.

It’s just gone from a blacksmith pounding on metal to a machine shop operator with a lathe to a programmer with a 3D printer. Also you still need the lathe to turn a gun barrel so maybe it hasn’t even come that far...

No you don't, you can ECM rifling and a chamber, using 3d printed jigs.
