Ordinary printers are devices that are present in many homes. Nowadays, however, 3D printers are becoming popular, thanks to which spatial prints can be obtained. They can be used not only by designers, but also... in hospitals. Researchers in Spain have developed a 3D printer which can create a fully-fledged human skin. Such skin could be used for transplants in burn victims, as well as for research in the pharmaceutical and cosmetics industries.
