With 3 D Printing, Anybody Can Manufacture and Sell

Just like we have a 2D printers which prints on paper, we also have this 3D printer which manufactures real world objects

A 3D printer is robot which deposits material on a bed, with the help an extruder, layer by layer as per the CAD (Computer Aided Design) of the object.

Ford engineers send CAD files between facilities, then build prototypes at workstations

using MakerBot Thing-O-Matic 3D printers.
