Scientists Turn E. Coli Into ‘Living Ink’ for 3-D Printing

It seems like scientists and innovators are able to 3-D print just about anything—bridges, schools and even prized cuts of Wagyu beef. Now, a team of researchers introduced a new printing material: an entirely living ink made of microbes, which they hope can be used to improve building materials, human health and the environment, reports Sabrina Imbler for the New York Times.

To make this microbial ink, scientists genetically engineered the bacteria E. coli to grow two types of protein polymers called curli nanofibers, according to a paper published last week in the journal Nature Communications.
