Abstract

One aspect of the invention provides a method for multi-nozzle biopolymer deposition of heterogeneous materials to create or modify a composite biopolymer multi-part three-dimensional assembly having at least one biomimetic and at least one non-biomimetic feature. The method includes: (a) utilizing a CAD environment to design and/or modify a composite multi-part assembly, thereby producing a CAD design; (b) converting the CAD design into a three-dimensional heterogeneous material and multi-part assembly model in a format suitable for three-dimensional, multi-nozzle printing, wherein the design comprises at least one biomimetic feature and at least one non-biomimetic feature; and (c) printing the composite assembly by simultaneously depositing the heterogeneous materials using multiple, different, specialized nozzles, wherein the simultaneous depositing includes direct deposition of cells.
