The Pioneer of 3-D Printing
Bre Pettis
When MakerBot, the 3-D-printing start-up, was bought by manufacturing giant Stratasys in June for $403 million, it was clear that Bre Pettis' brainchild was destined for more than just making tiny Star Trek figurines. But serious business has always been the goal of the 41-year-old CEO: MakerBot's Replicator printers, which debuted last year, are already being used to make prosthetic hands for children and prototypes for the next generation of Hubble telescopes. In August, the Brookyn-based entrepreneur launched the Digitizer, a desktop scanner that reproduces objects up to eight inches tall, like a 3-D copy machine. "Just wait," Pettis says. "Soon, when you want something, instead of buying it, you'll say, 'I could make that.'"
