Yes, you need to buy some actual gun parts, like a barrel. But, at least as far as 3D printed AR-15s the lower receiver is the only part of the gun that you need to pass a background check for and that can very easily be 3D printed. Literally everything else can be bought online and shipped to your house.
And then there’s the FGC9 2.0 (RIP JSTARK), which can be built using only 3d printed and common hardware store parts (including a homemade ECM rifled barrel.)
