The MakerBot CupCake CNC 3D printer caught my eye from all the way across the room, and MakerBot founder Bre Pettis didn't seem all that surprised that his seemingly cobbled-together DIY Frankenmachine made from wood, acrylic plastic, PCB and messy wires was drawing a crowd. After all, it was artfully melting lumps of ABS plastic into 3D marvels. For $750, it could do the same for you.
The machine gets its name since you really won't be able to make anything larger than a cupcake. But, oh, what you can make. Pettis showed us a replica of the Empire State Building (sans antenna — thanks Matt Buchanan) made from images found on Google, which was rendered with impressive detail. Pettis also showed a more practical use for the 3D printer, when he made a working lens cap for a camera.
If you're squeamish about building it yourself, you can also buy a pre-assembled CupCake for $2,500. There are also plans at MakerBot to develop a 3D scanner, so you can faithfully replicate complex objects.
