If 3-D printing is indeed going mainstream, it will be in large part because of people like Bre Pettis, co-founder of the Brooklyn, New York-based 3-D printer company MakerBot. The company produces affordable desktop 3-D printers, with a basic unit selling for around $2,000. At South by Southwest this year, Pettis unveiled the Digitizer, a new MakerBot scanner that can scan a physical object–say, a golf ball or a garden gnome–and record its precise physical dimensions so it can be re-created by a 3-D printer. And that, he says, is good news for entrepreneurs.
