3D printed AR lower receiver doesn't meet expectations

One of the more interesting technologies for creating rapid prototypes and other items is 3D printing. 3D printing is capable of producing just about anything you can imagine from implantable cartilage for medical uses, to prototype parts and even weapons.

A project called Defense Distributed has been working on 3D printer files that allow users to create components to build their own guns using a 3D printer. A group of testers used a 3D printed gun part design from creator HaveBlue to produce an AR lower receiver (the lower receiver is a key component of the weapon that receives the rifle cartridge from the magazine) and headed to the gun range.

Unfortunately, it appears that recoil pressure in the completed weapon was too much for the buffer section of the 3D printed lower. The buffer is a section that separates the stock from the upper receiver reports NBC News. The part failed after firing only six shots. To make the failure even more embarrassing, the testers were using ammunition specifically designed for lower recoil.
 
The creator of the part claims to have printed his own and used it to fire hundreds of rounds.
 
While the firearm breaking in half while in operation seems to offer the potential for harm to the shooter and those nearby, the testers say that the only damage the operator faces is that of ego. When the weapon failed, the spring and buffer popped out of the tube and fell to the ground according to the testers.

I had not heard of this Godwin's law. I looked it up. No I would not have included it but I did laugh my ass off.

Some what on topic.

I did a lot of research on this topic, 3d printing of firearms, yes there is a sub-branch that is completely capable of printing working firearms with the exception of the springs and barrel. Which is quite a caveat.

What I think is really missing in the discussion is given the promise of 3d printing technology why would you copy a firearms design from circa 1960? Even if you have to add in the conventionally built barrel why not build a weapon that uses the 3d printing technologies strengths. Think of the unique weapons that could be produced. It would be magical.

Oh to be honest, I used to sell firearms so my perspective on them is often different than other peoples.

and it will be called the iGun
