Well, guess what, it happened -- a RepRap created a copy of itself. And then the child created a 3rd generation.

The child machine made its first successful grandchild part at 14:00 hours UTC on 29 May 2008 at Bath University in the UK, a few minutes after it was assembled.
I cant stress enough go cool this technology is. The prospect of people being able to create all sorts of necessary products in their basement, paying only electrical and raw materials costs, promises to revolutionize the way we live.
