“TreeHugger.com”:http://www.treehugger.com/ posted an “article”:http://www.treehugger.com/files/2007/04/downloading_des_5.php the other day about a cool DIY project at the “Evil Mad Scientist blog”:http://www.evilmadscientist.com/. It’s all about a home-made “3-D or CNC printer”:http://www.evilmadscientist.com/article.php/3printerpreview that uses sugar as the primary building material. TreeHugger already did a cool review of the machine with their post, but they neglected to mention the really cool “toaster mod”:http://www.evilmadscientist.com/article.php/cnctoast pictured below.

For a really great treatment about just how revolutionary 3-D printing could be, read Charles Stross' "Singularity Sky":http://www.librarything.com/work.php?book=14432707.
