Abstract

A method and apparatus for additive manufacturing that includes a nozzle and/or barrel for extruding a plastic material and a supply of polymeric working material provided to the nozzle, wherein the polymeric working material is magnetically susceptible and/or electrically conductive. A magneto-dynamic heater is provided for producing a time varying, high flux, frequency sweeping, alternating magnetic field in the vicinity of the nozzle to penetrate into and couple the working material to heat the material through at least one of an induced transient magnetic domain and an induced, annular current.
