Printing in 3D

Well one of the most exciting gadgets i've been using recently isn't the remote control watch (although that is pretty cool) but a 3D printer. The printer basically works by melting and extruding ABS plastic in a 3D pattern you have designed in some CAD software like Solidworks.
So far I've printed an assortment of servo brackets, a mounting assembly for my PhD research and a some hardware for Adam's CNC machine design.
For those curious the printer is this one: http://pp3dp.com/
