Abstract:
1. A fabrication process for forming a multi-layer three-dimensional structure from at least one structural material, comprising: (a) forming and adhering a given layer of at least one structural material and at least one sacrificial material to an at least partially formed previous layer and/or to a substrate; and (b) repeating the forming and adhering of (a) a plurality of times to build up a three-dimensional structure from a plurality of adhered layers; wherein the formation of a plurality of the adhered layers comprises beginning a deposition operation to form a portion of a current layer prior to completing a deposition operation to form a portion of a prior layer, and wherein after formation of the adhered layers, separating at least a portion of the at least one sacrificial material, located on multiple layers, from the at least one structural material to release multiple layers of the three-dimensional structure.
