This overweight human figure is a 3D nano object printed by the Vienna University of Technology's recently announced
3D printer. The printer, which uses a technology called "two-photon lithography," prints with liquid resin that is hardened by a focused laser beam. The printer can fabricate tiny nanometer scale structures, like the human figure above, that are the size of a grain of sand at speeds up to five meters per second.
Other objects that have been fabricated with the 3D printing technology include a race car, cathedral and the London Tower Bridge. You can find images of these objects here
