A group of researchers from Delft University of Technology (TU Delft) discovered that it's possible to 3D print bacteria. Why? If you're familiar with the 3D printing industry, you're likely familiar with graphene and how excited everyone is about it. It truly is a brand new material, having been patented for 3D printing less than two years ago, and its super strength, flexibility and electrical conductivity make it highly desirable for manufacturers in all areas. What the TU Delft researchers discovered was that if you place certain types of bacteria on flat sheets of graphene oxide, they can turn it into a reduced version of the compound by pulling oxygen atoms off the material as they metabolize. That reduced compound has many of the same properties as graphene, but is easier to produce in large amounts. Reducing graphene oxide isn't new; it's normally done with chemicals or high heat, but using bacteria is a lot cheaper and more environmentally friendly.
