Abstract: Disclosed is a method to 3D print materials with defined bacterial communities into controlled, complex 3D structures, and compositions. The technique includes first providing an ink composition that includes a pre-polymer composition and a microorganism, where the pre-polymer composition includes a polymerizable monomer, a cross-linking agent, the photoinitiator, and a solvent. The technique also includes 3D printing a pattern in a hydrogel support matrix using the ink composition where the hydrogel support matrix is in a container. The technique may also include forming a 3D printed engineered living material by curing the 3D printed pattern.
