Doodad: Makerbot

If you care at all about manufacturing and don't already know about Makerbot, you need to check it out. Mechanically versed tinkerers and hobbyists use this site to design and order their own 3D printers—once known as rapid prototype machines—which use an ink-jet-like process to fabricate solid objects from plastics and metals. The recipe for the object, naturally, is a digital design, housed at Thingiverse.com, that goes straight from your computer to your printer.
