Replicating prototyper

"Wealth without money..." I've been thinking about a device like this... A device that will let you create things that you need. All you need is the raw (or hopefully recycled) material. More info here. The RepRap project is working towards creating a universal constructor by using rapid prototyping, and then giving the results away free under the GNU General Public Licence to allow other investigators to work on the same idea. Nanotechnology should also be able to do this. But I dont know the timeline for either. I remember reading about a device that would take material and replicate things, wonder if I could find it...
