This 3D-printed ‘living ink’ could someday help with skin replacements
Tomorrow’s replacement skin could be 3D printed from a new ink embedded with living bacteria.
Bacteria are able to do everything from breaking down toxins to synthesizing vitamins. When they move, they create strands of a material called cellulose that is useful for wound patches and other medical applications. Until now, bacterial cellulose could only be grown on a flat surface — and few parts of our body are perfectly flat. In a paper published today in Science Advances, researchers created a special ink that contains these living bacteria. Because it is an ink, it can be used to 3D print in shapes — including a T-shirt, a face, and circles — and not just flat sheets.
Bacterial cellulose is free of debris, holds a lot of water, and…
