Printing Objects in Three Dimensions

I came across a great article today on Ars Technica about a do-it-yourself personal fabrication machine.

What's a fabrication machine? It's this:



Basically, Evan Malone, a mechanical engineering grad student at Cornell University, has designed a rapid prototyping 3D printer that you can build for yourself for under $3,000.00.

The article linked above points out that this is an equivalent cost range to early personal computing. I don't know how much this will bear out as an analogy, but if the flexibility, robustness and sophistication of this machine compounds anywhere near as quickly as those early computers did, this could well be one of the first signs of a true revolution in the way things are done!
