3D printer helps burn victims

Engineering students from the University of Toronto have used 3D printing technology to create a new machine called PrintAlive that has the capabilities to produce skin grafts for burn victims. The machine works by using hydrogel, a substance often used for bandaging, and a patients own stem cells to create ‘strips’ of regenarative cells. The creators of PrintAlive later won the James Dyson Award and are now using their prototype in hospitals of poor countries.
