23. Can you make a barrel without metal though? I highly doubt that. From what I've read about 3d

printing, none of the plastics used would come close enough to being strong enough for a gun barrel. At least not a gun barrel thats able to shoot multiple rounds without serious danger to the operator.

Also, with a 3d printer making the parts, there would still be assembly required to make a functioning weapon. Its not like you can just download an AR15 file from NRA.com and print out a ready to fire Bushmaster.

The fact is that its more trouble than its worth to DIY an assault rifle when you can just go to your local gun show and buy one off the shelf. Anyone who has the skills needed to build an assault rifle from raw materials probably does it legally and gets paid for it.

LOL! But where are you going to get the poison dart frogs from? Gorp Feb 2013 #35

I am sure someone in FL has released them into the wild and they're probably all over the Everglades Erose999 Feb 2013 #38

I'd guess the pythons ate all the frogs. Gorp Feb 2013 #40

Thats why they were released, as population control for the pythons. Erose999 Feb 2013 #44

I doubt the poison would affect the pythons. Gorp Feb 2013 #49

Paintball is a good analogy. Same basic idea. But 3-D printing was science fiction until recently. Gorp Feb 2013 #56
