Revolutionary 3D Skin Printing on The Rise
Researchers at Penn State have developed a groundbreaking method using 3D printers to create multi-layered living skin directly onto significant wounds on rats. The process involves different bio-inks, including proteins and molecules extracted from fat tissue, stem cells, and a binding solution. This technique promotes scar-free skin repair and has the potential to revolutionize skin regeneration in humans, eliminating issues such as scarring and skin graft failure.
