DIY 3D-printed guns get go-ahead from Trump Admin

you can print pretty much everything of the outside of the gun. and make your own barrel.
or you can print a disposable gun that will shoot once.

at least thats what ive seen so far.

THIS!
Plastic firearms PARTS are fine in some places like the stocks and forearms and lower receiver, but you can't make a bolt, a barrel or a firing pin out of plastic, in fact few of the parts would stand up to use. You can't use the same plastics used by manufacturers to make Glocks and other "plastic" guns, they are extinction molded and made of a much stronger polymer than plain old ABS plastic. ABS is plastic-bottle like in consistency but a little harder
And I'll tell you something else, a skilled machinist can copy a firearm WITHOUT the CNC files , though it would never be a precise copy it only has to function like the original. The hardest thing for the "do it yourselfer" to fabricate is a barrel, the forging and drilling involved require a lot of skill and expensive equipment, especially if you are making rifle barrels. A large lathe is a must have as is a forge.

.

Not "extinction molded", I meant "injection molded".

Yes, but the Glock is not ALL plastic/polymer.

I'll take my glock thank you

good

Lighter but does the trick.

its mostly a statement of freedom imo.
because sure they can control official sales from big company's. same as they control mainstream media. but they cant control 3d prints in the same way they cant control individual free speech on the internet (even tho they try)

Mig printer

With proper temp control and continuous annealing such as in a inert gas oven. You could have a reasonable weapon that only needed a reamer for a final operation.

I used to do cobalt overlay in a similar way.
