Three-dimensional printing is here.
The implications of this technology are profound. Sidestepping the channels of mass production, 3-D printing affords individuals unprecedented power of creation. In the creative community that has embraced it, people speak about its potential to transform our global culture. It is, they say, the democratization of fabrication.
