ETH researchers have developed a biocompatible ink for 3D printing using living bacteria. This makes it possible to produce biological materials capable of breaking down toxic substances or producing high-purity cellulose for biomedical applications. There will soon be nothing that cannot be produced with 3D printing. However, the materials used for this process are still 'dead matter' such as plastics or metals. A group of ETH researchers led by Professor André Studart, Head of the Laboratory for Complex Materials, has now introduced a new 3D printing platform that works using living matter. The researchers developed a bacteria-containing ink that makes it possible to print mini biochemical factories with certain properties, depending on which species of bacteria the scientists put in the ink. Adding bacteria with desired properties .
