We Can Print Human Skin Now

This may be technology at its coolest. Or grossest. Or both. We’d say both. Scientists in Madrid have figured out a way to produce functional sheets of human skin using a 3D printer. They published their results in the journal Biofabrication.

Scientists have really seized 3D printing as a solution to all kinds of problems. In the last few years, they’ve developed techniques for printing cardiac stents, artificial rat models to spare real rats from dissection—even human jawbones and ears. Other researchers have been hard at work growing human skin in the laboratory.

The team in Madrid decided to put the two concepts together. As you can imagine, this was not a simple matter of loading up the ink and hitting a button. The team built a brand-new type of bioprinter…
