Patent ID: 7229542

Claim:
A method of forming a three-dimensional molded structure, comprising: (A) providing a mold having a mold structure that comprises at least one sacrificial material and at least one structural material, the at least one sacrificial material and the at least one structural material each have a surface that define a portion of a desired molding pattern, wherein the mold structure is formed, at least in part, by electrochemically depositing multiple layers, each comprising the at least one sacrificial material deposited adjacent to and adhered to a previously deposited layer that comprises the at least one sacrificial material and wherein the at least one structural material is electrochemically deposited during formation of at least one layer; (B) placing flowable molding material against the desired molding pattern and allowing or causing the molding material to solidify to form at least a portion of the three-dimensional molded structure; and (C) separating the three-dimensional molded structure from a portion of the mold, wherein the separating is accomplished, at least in part, by destroying the desired molding pattern defined by the at least one sacrificial material without significantly damaging the molding material such that an image of the molding pattern remains on a surface of the three-dimensional molded structure, and wherein the at least one structural material, after destroying the desired molding pattern, is restrained to a desired location by the molding material and becomes part of the three-dimensional structure.
