Manchester University scientists have developed a printer able to produce human skin to help wounds and burns heal. With more research it could even replace broken bones.

The cells are put into a special printer ink liquid and artificially multiplied. Then, the printer prints the cells on to a plastic surface, which acts like a scaffold to support the cells. Experts say that the plastic could then be surgically attached to the damaged part of the body and the plastic would dissolve naturally, allowing the body to use the strip of cells to repair the injury.
