In this episode of Founder Stories , host Chris Dixon takes a look at a 3D printer while talking to the maker behind the MakerBot , Bre Pettis . If printing 3D objects sounds impressive, think about this. Pettis thinks "it's early days"—drawing comparisons to early PC's like the Altair. About the size of a mini-fridge, the Makerbot ships for $1,299 and allows users to create their own objects via CAD software (or users can select from "more than 10,000 things" on Thingiverse says Pettis) and print them out in a matter of minutes.
