Title: Rapid prototype extruded conductive pathways

Patent ·
OSTI ID:1258001

A process of producing electrically conductive pathways within additively manufactured parts and similar parts made by plastic extrusion nozzles. The process allows for a three-dimensional part having both conductive and non-conductive portions and allows for such parts to be manufactured in a single production step.
