Students at the University of Toronto have come up with a way to 3D print functional human skin. This amazing achievement has won the students the 2014 James Dyson Award. They say the technology will dramatically decrease the cost for skin grafts for burn victims and others who need such surgery. Not only will it decrease cost, but it will make skin grafts more widely available to people and places that may have struggled to afford the technology needed to preform traditional skin grafts.
