  • Patent number: 5501784
    Abstract: A microstructured mold with at least one open cavity is produced from a solid body (metal, ceramic, glass, stone or monocrystalline material) by precision mechanical machining, additive or subtractive structuring. The cavity is filled and the mold covered by a flowable material and the solidified flowable material is separated from the mold giving a microstructure element. Alternatively, the top portion of the solidified flowable material is removed to expose the surface of the mold and the solidified material filling the cavity. A layer of conductive material is applied to the exposed surface and remaining solidified material. Then the conductive layer and the remaining solidified material are separated from the mold to provide a structure with a shape complementary to the mold. A layer of metal is electrodeposited on the complementary structure and, finally, the metal layer is separated to produce a metallic microstructure element.
