Description
3D printers: They're not your granddad's daisy wheel printer, or your mom's dot matrix. In fact, they bear little resemblance to today's document or photo printers, which can only print in boring old two dimensions. They can build objects from scratch—or rather, from a CAD or 3D scanner file—out of a variety of materials. They're gaining traction: You may have seen 3D printing demonstrated on the Colbert Report or other shows, and they filled a large pavilion at Maker Faire. Though still mostly found on shop floors or in design studios, and in the hands of hobbyists, they'll soon be coming to homes near you (if not your own), to be found on workbenches, in rec rooms, even in the kitchen.
