Scientists from the University of Tokyo Hospital work on creating a special 3D bio printer, which is able to create human bones, skin and joints.

Tsuyoshi Takato, a professor at the University of Tokyo Hospital, announced that in case of conventional implants scientists need cartilages from patients' own bodies, but due to the 3D bio printer, specialists will be able not to remove source materials.

Researcher also noted that the team of experts plans to start the clinical trials of the skin, printed on a technological device in three years.  Then doctors will work on the formation of cartilages. Professor thinks doctors are able to grow stem cells and protein similar to collagen. Researchers also want to create some human organs, including inner spongy bone substance and bone hard surface.

The main difficulty of the technological innovation is that the heat, generated by the 3D-bio printer, may destroy the basic structural and functional units of the human body.
