US Patent 10569464 Connecting metal foils/wires at different layers in 3D printed substrates with wire spanning

A three-dimensional electronic, biological, chemical, thermal management, or electromechanical apparatus and method of configuring such an apparatus. In an example embodiment, an apparatus can include a substrate and one or more layers of a three-dimensional structure configured on and/or from the substrate. The three-dimensional structure includes one or more internal cavities configured by an extrusion-based additive manufacturing system enhanced with a range of secondary embedding processes. The three-dimensional structure can be configured with one or more structural integrated metal objects spanning one or more of the internal cavities of the three-dimensional structure for enhanced electromagnetic properties.
