Researchers develop a skin printer that works like a paint roller, depositing bio ink that speeds up wound healing. A new handheld 3D printer can deposit sheets of skin to cover large burn wounds – and its “bio ink” can accelerate the healing process.
The device, developed by a team of researchers from the University of Toronto Engineering and Sunnybrook Hospital, covers wounds with a uniform sheet of biomaterial, stripe by stripe.
The bio ink dispensed by the roller is composed of mesenchymal stroma cells (MSCs) — stem cell...
