I assume this is not OT, because 3D printing is indeed a valid machining/fabrication technique. It just hasn't been applied to weapons very often.
I will apologize in advance for the snarky, in-your-face, "throw a middle finger to Congress" tone of the article. I'm aware of the forum's prohibition against politicization, and hope the article's attitude doesn't offend. In addition, the video is just a bit boring, as it takes them a while to shoot off all 600 rounds.
Nevertheless, the article and video do offer what appears to be a very good proof-of-concept demo for 3D printing of this receiver.
That said, I'll bet that the AR being demo'd is a gas piston version. I'd expect that the amount of hot gas blown into the receiver by a "traditional" AR action would soften and melt the plastic long before 600 rounds were fired.
