Patent ID: 7828952

Claim:
A fabrication process for forming a multi-layer three-dimensional structure, comprising: (a) forming and adhering a layer comprising a first material and a second material to a previously formed layer; 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 at least a plurality of layers, comprise: (1) depositing the first material onto a previously formed layer, wherein the first material is a structural material; (2) selectively etching the first material to a desired depth to create voids; (3) depositing the second material at least into the voids created by the selective etching of (2), wherein the second material is a sacrificial material, wherein at least one of the depositing of the first material or depositing of the second material comprises an electrodeposition operation, and (c) after repeating the forming and adhering the plurality of times, removing the sacrificial material from the structural material to reveal the multi-layer three-dimensional structure formed from the structural material.
