US 11,305,488 B2 · Process for producing three dimensional structures

Abstract

A method for producing a 3D structure, according g to which a composite conductive substrate (CCS) with a conductive layer and a non-conductive layer is provided and a conductive pattern is determined for each layer of the 3D structure. A first layer of non-conductive matter on the CCS is printed, such that the conductive pattern of the first layer left empty from the non-conductive matter. The empty conductive pattern is filled with conductive matter by electroplating and for each following layer, in turn, printing, on the previous layer, a layer of non-conductive matter, the conductive pattern of the present layer left empty from the non-conductive matter; plating non-conductive areas of the previous layer that are left uncoated with conductive matter; and filling the empty conductive pattern of the present layer with conductive matter by electroplating.
