I heard about this on the radio (gotta love the CBC!). Apparently, such a thing is possible. Not exactly the replicator from Star Trek, it does produce three-dimensional objects. Complete instructions on how to build your own are published on the web for free and available to everyone. If you want to make one yourself, go to: http://reprap.org/bin/view/Main/RepRapOneDarwin Or if you just want to see some of the things you can make with this printer, go to: http://reprap.org/bin/view/Main/ItemsMade
