3D Printed Rifle Breaks After 6 Shots

Watch: 3-D Printed Assault Rifle Breaks After Just 6 Shots | Popular Science

There you saw Cody Wilson, who heads the project, test-fire one round to see if it worked, and then hand the weapon to another member of his group, who only unloaded five rounds before the gun fell apart. The magazine had 10 rounds.

The team thinks the problem was recoil, which caused the plastic to become unhinged. The threads connecting the receiver to the stock worked just fine--the o-ring just snapped. The group explains further in their blog post.

Darn. Keeping an eye on their progress and thinking of building a 3D printer...

BTW, here's the printer I want to build:

I'm surprised it made 6 rounds. Just think..... homemade guns. No wait period to buy, no controllable regulation at all.

Someone is going to find a way to restrict it.... (or so they think...)

Well, the lower receiver doesn't really take much load. The upper is where the big forces are. Think about this...there are quite a few polymer framed handguns out there. You should be able to print your own frame and then just buy a slide and some internals (pins, springs, etc.). Just don't try to sell it.

but you can build your own AK from parts, a receiver flat and a press

He was a moron for leasing the machine.

A little help here.

If I understand this, wherever I get the file from, I need the equipment and raw materials to build the thing, yes?

So, technically speaking, as long as I have plastics and metals and the equipment to form them into parts, put them together...?

There are protyping websites that you can upload files to and they will make the parts and send them back to you fairly cheaply. One of the ways that can build the parts is FDM (printing).

I can see using the three D printer to make castings..

Print your gun part, encase it in sand, pour in your molten metal which melts and displaces the plastic... perfect casting every time.

It can probably print all usable parts but springs...

I don't think you need a "file" but an original copy..

If you HAVE an AR 15, you can take it down and scan it and produce the parts.

That's my understanding anyways.

We're all going to resort to being the Mujhadeen.. making guns in our garages and basements to ward of the Sovie... I mean Liberals.

Exactly.
