Abstract
Abstract A process of electroforming and etching a material to produce an integral supporting fixture comprising the steps of electroforming a layer of depositant onto and into metal mesh, applying etchant resist to the depositant in the shape of the supporting fixture, etching away the excess depositant so as to leave only an integral supporting fixture, removing excess resist, cutting the supporting fixture from the remaining mesh, and crimping the integral supporting fixture so as to tighten the mesh supported therein.
