Hey all,
I just found this online and was blown away at the possibilities!
http://www.makerbot.com/
MakerBot is a 3D printer (it builds 3D shapes using plastic) that you assemble yourself, and it only cost $750US (3D printers generally go for tens of thousands of dollars)! Biggest shape it can build is 4"x4"x6" (inches).
You design your 3D object in CAD, upload it to MakerBot and it 'prints' it out
What can you make with a 3D printer?
They mention they use ABS plastics (apparently same as Lego blocks), as it heats up to 2000 degrees I'm sure other plastics could be used..
