Portable 3D printer can print skin on human wounds

Imagine using a 3D printer to cover and heal wounds. This is the idea of ​​a University of Toronto researcher developing a portable handheld 3D skin printer. The machine can apply 3D printed skin to people. They said that this is the first device that can form skin directly on the wound within two minutes. The application of this technology is extensive and may have a devastating effect on the industry.

Researchers say that a handheld 3D skin printer can apply a layer of skin tissue directly to a person to heal and cover the wound. They add that although it is similar to a typical skin graft, it does not require healthy skin from the donor and then transplants it to the patient.
The device basically looks like a white tape dispenser, and the user uses a "bio-ink" skin tissue to print the skin in 3D in the affected area. They have not yet tested the printer on human patients, but researchers have been able to prove this idea in pigs.
