1. A process for the production of a metallic element, comprising the steps of:

  • (a) forming a mold having an open cavity on one surface thereof from a solid body by mechanical machining, additive structuring or subtractive structuring,(b) filling the cavity and covering the mold with a flowable electrically non-conductive material,(c) solidifying the flowable electrically non-conductive material to form a solid layer in contact with the surface of said mold and filling said cavity,(d) removing a portion of said solid layer to expose the surface of said mold and said cavity filled with solidified flowable material,(e) applying a layer of conductive material to and covering the exposed surface of said mold and filled cavity,(f) separating the conductive layer and solidified flowable material in the cavity from the mold to provide a structure having a shape complementary to the mold,(g) electrodepositing a metal layer on the complementary structure, and(h) separating the metal layer from the complementary structure to provide a metallic element.
