The whole 3d printed gun scare boggled my mind. Making a single fire weapon with some pipe is so easy nearly anyone could do it. Getting the ammunition would be the hardest part were I live. Using a 3d printer take a lot more skill and effort.

I think a lot of the scare comes from assuming you can easily 3D-print something functionally identical to a handgun you'd buy at a store. There's also the legitimate concern that 3D printing will one day be much easier.

Of course, the plastic guns are practically useless:

I thought the panic was because 3d printed guns are untraceable and can be made from materials that don't show up on airport scanners, etc.

(Yes, you can buy a bunch of parts off the internet and build your own untraceable gun today, or so I've read.)
