In a DIY project similar to the Fab@Home people, the Maker Faire will feature this 3D fabrication device. The device works similar to other 3D printing & prototype machines in that a solid object is built from a computer model by creating the model layer by layer out of a cheap substrate. The difference between this machine and others is that this machine uses what the makers call SHASAM, or selective hot air sintering and melting, to melt layers of sugar into an object. A hot air jet melts sections of a bed of sugar to form the various layers of a 3D object.

More about at home fabrication. I read about this story on Boing Boing, which was a blog post from this guy, who originally read about this machine on treehugger a few years ago. Wacky Internet.

Fab@Home self-assembled fabricators drop the cost of 3D printing to about $2400. The machine uses an extraction process to create objects layer by layer. Different types of substrates have been used thus far to build objects; silicon, chocolate...Rush out and get your kit today! Or send me $2400 so I can play with one!
