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.

The embodiments described herein provide for lightning protection in aircrafts constructed with Carbon Fiber Reinforced Plastic (CFRP). In one embodiment, the apparatus includes a first Carbon Fiber Reinforced Plastic (CFRP) panel, a second CFRP panel that overlaps with the first CFRP panel in a vertical direction, and a fastener to join the first CFRP panel with the second CFRP panel, the fastener extending in the vertical direction in an area where the first CFRP panel and the second CFRP panel overlap. The apparatus further includes a plurality of electrically conductive pins in each of the first CFRP panel and the second CFRP panel, wherein the pins extend in the vertical direction proximate to the fastener to electrically connect the first CFRP panel and the second CFRP panel in the area where the first CFRP panel and the second CFRP panel overlap.

The material set can include a thermoplastic polymer powder having an average particle size from 20 m to 100 m, a conductive fusing ink comprising a transition metal, and second fusing ink. The second fusing ink can include a fusing agent capable of absorbing electromagnetic radiation to produce heat. The second fusing ink can provide a lower conductivity than the conductive fusing ink when printed on the thermoplastic polymer powder.

A partially molded substrate and a partial molding apparatus and a method thereof, which cover and mold each of one or more conductors formed on the substrate with the insulator to prevent the sizes of the substrate from being increased due to molding, thereby efficiently preventing high voltage between the conductors on the substrate from being applied, and thereby preventing interference around the conductor.
