Claim Text:
1. A fabrication process for forming a multi-material, multi-layer three-dimensional structure, comprising: (a) providing an initial multi-material layer on a sacrificial material on a substrate; (b) forming and adhering a first successive multi-material layer to the initial multi-material layer and forming any additional successive multi-material layer or layers on and adhered to the first successive multi-material layer or to a subsequently formed successive multi-material layer to build up a three-dimensional structure from a plurality of adhered multi-material layers, wherein each multi-material layer comprises a first structural material and a sacrificial material, wherein at least one of the adhered multi-material layers further comprises a second structural material, and wherein the three-dimensional structure is formed from the first structural material and the second structural material; (c) after formation of the plurality of adhered multi-material layers, separating the sacrificial material forming part of each of the plurality of adhered multi-material layers to reveal the three-dimensional structure comprising the first structural material and the second structural material; wherein formation of the at least one multi-material layer of the plurality of adhered multi-material layers comprises formation of a first of at least two consecutive multi-material layers and comprises: wherein the formation of an additional multi-material layer of the at least two consecutive multi-material layers, which is different from the first of the at least two consecutive multi-material layers, comprises: wherein the sacrificial material and first and second structural materials are metals and at least one of the depositing steps comprises an electrochemical deposition step.
