Hkable Biological 3D (China) Co., a joint venture between Hkable US and Jintai in Chongqing, are building a 3D printing factory for medical products, starting with splints and artificial limbs in the beginning, then developping more advanced stem cell-printed products. WU Jun, director of the Burns Institute at the Southwest Hospital in Chongqing, is testing the process for printing human skin on pigs. Across China, there have been a number of successes using 3D printing for surgical purposes.
In June, doctors in Peking University Third Hospital replaced five vertebrae with 3D-printed replicas in a cancer patient. The 3D-printed vertebrae measured 19 centimeters, the longest ever in a successful operation.
