Abstract:
1. A method for fabricating a three dimensional (3D) structure, the method comprising: sequentially depositing a plurality of mold material layers such that each of said plurality of mold material layers has a corresponding thickness, and such that the plurality of mold material layers collectively form a multi-layer mold; individually patterning each of the plurality of mold material layers in accordance with a digital description such that each said mold material layer defines a void portion; and sequentially depositing a modeling material into each said void portion before depositing a subsequent mold material layer of said plurality of mold material layers such that said modeling material deposited into an associated said void portion forms a substantially two-dimensional modeling material portion that fills said associated void portion and has the same thickness as an associated said mold material layer defining said associated void portion, whereby said sequentially formed substantially two-dimensional modeling material portions disposed in said plurality of mold material layers collectively form said 3D structure.
