Method of Furnishing Three-Dimensional Objects with Electrically Conductive Structures having Low Topography and Low Surface Roughness

Method of producing an assembly of one or more structured members from an electrically conductive material on a plastic material substrate, the method comprising at least the following steps:

• providing an at least locally flat substrate from plastic material,
• printing on a surface of the plastic material substrate a track or tracks of a first predefined thickness and corresponding to an intended course of the one or more structured members from a material with strong adherence to both the plastic material substrate and the electrically conductive material,
• printing a masking material with the first predefined thickness directly on the surface of the plastic material substrate, the masking material having an adherence to the plastic material substrate that is larger than an adherence to the electrically conductive material,
• wherein the adherence of the track material to the electrically conductive material-is larger than the adherence of the masking material to the electrically conductive material,
• applying an atmospheric plasma spray process to cover the track or the tracks and at least a portion of the masking material adjacent to each respective track with the electrically conductive material with a second predefined thickness, and
• applying a cleaning process to remove the electrically conductive material from at least the portion of the masking material adjacent to each respective track.
