3D bioprinter patches up wounds using a patient's own skin cells
To help patch up large wounds that might normally require a skin graft, researchers at Wake Forest Institute for Regenerative Medicine (WFIRM) have developed a new bioprinter that can print dual layers of a patient's own skin directly into a wound.
The idea of 3D printing skin has been in development for a few years. In 2014, a prototype machine was unveiled that could print large sheets of human skin that could then be cut to size and grafted onto a patient. The tech evolved over the years into more detailed machines and eventually a handheld device that works like a tape dispenser for skin.
