摘要： 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.
