A handheld 3D printing device able to print skin directly onto wounds could offer a tailor-made approach to wound healing.
Developed by a team from the University of Toronto, the shoebox-sized device dispenses sheets of alginate-based tissue. One side of the sheet is coated with bio-ink that contains skin cells, collagen and fibrin—a key protein in would healing. The device is easy to use, and the sheets can cover the wound in two minutes or less, without requiring the washing and incubation period common in most 3D bio-printing devices.
