Zusammenfassung:	A method includes providing an electrically conductive mandrel having an outer surface layer comprising a preformed pattern. The metallic article is electroformed. The metallic article includes a plurality of electroformed elements formed in the preformed pattern on the outer surface layer of the mandrel. The plurality of electroformed elements have a first side adjacent to the outer surface layer of the mandrel and a second side. The metallic article is separated from the mandrel. The plurality of electroformed elements are interconnected such that the metallic article forms a unitary, free-standing piece. A solution is applied to create a blackening of the first side of the plurality of electroformed elements.
