An extrusion printing process for conductive materials and a conductive material extrusion system. The process includes attaching a counter-electrode to a first side of a substrate. A drive voltage is applied to the counter-electrode and to a conductive material to be extruded onto a second side of the substrate, opposite the first side. The conductive material is extruded onto the second side of the substrate while the drive voltage is being applied to the counter-electrode and conductive material. The conductive material is selected from a metal having a melting point ranging from about −20° C. to about 150° C.
