  • Patent number: 10596759
    Abstract: An extrusion assembly, a method of constructing an extrusion assembly, and an additive manufacturing system including an extrusion assembly are disclosed. The extrusion assembly includes an extrusion die; a channel having an inlet and an outlet, which is in fluid communication with the extrusion die; and a heating element that melts a filament material drive through the channel so that the melted material is extruded by the extrusion die. The heating element can be helically wound about the channel or extend parallel to the channel, among other configurations. Further, the extrusion assembly includes a temperature sensor that is positioned adjacent to the channel between the extrusion die and the heating element. The channel, heating element, and temperature sensor are enclosed together within a sheath as a single integral unit. An additive manufacturing system utilizing the extrusion assembly can include a drive assembly, a support assembly, and a controller.

  • Patent number: 9301341
    Abstract: A medium-voltage heating element assembly. The medium-voltage heating element assembly can include a dual core having an inner core and an outer core. Segments comprising the inner core and the outer core can be staggered. Furthermore, the dual core can include a notch-and-groove interface to prevent axial rotation of the inner core and/or inner core segments relative to the outer core and/or outer core segments. A bushing of the heating element assembly can include a stepped region, and the bushing can interface with the dual core along the stepped region.
