Living skin can be 3D-printed, with blood vessels
For some perspective on why this matters. If you've never had a serious skin issue it's hard to understand how traumatic it is. I had basal cell carcinoma (a treatable skin cancer) in my early 30's on my nose. The treatment was careful excision of flesh from the affected area. The thing you can't prepare yourself for is how much and how deep the necessary removal is. Imagine a stack of 5 dimes taken out of your nose, and in it's place, a dark and gaping hole.It is impossible to look at oneself in the mirror without a sense of revulsion and horror. It then takes months of careful wound care for flesh to regrow. My case was simple, and I healed as quickly as could be expected. Most people who need skin grafts are not so lucky.I sincerely hope this technology is proven effective and makes its way out to the real world as soon as possible.
