3D printing types: a house, car, clothes and more

Chinese doctor Liu Zhongjun poses for pictures with a spine model implanted with a 3D-printed artificial axis, at Peking University Third Hospital in Beijing, Aug 14, 2014. Liu successfully implanted an artificial axis produced by a 3D printer into the spine of a bone cancer patient. This was the first time that an axis produced by 3D printing had been implanted into a patient, according to Liu. Normally, a diseased axis would be replaced by a standard, hollow titanium tube, said Liu. Picture taken on Aug 14, 2014.
