From video description:
A new invention being put together could signal a major breakthrough in the way patients with burns injuries are treated. A researcher in Canada has developed a three-dimension prototype printer which will produce human skin from a patient's own cells.
Doctors say it will revolutionise the process of skin graft operations, and can save the lives of hundreds of burns victims every year.
And not just skin: the technology may also pave the way for producing entire organs for transplants.
