| description | A liquefier assembly for use in an extrusion-based additive manufacturing system includes a liquefier tube compositionally comprising a metallic material, and having a first end and a second end offset along a longitudinal axis, and a flow channel extending from the first end to the second end. The assembly further includes an extrusion tip compositionally comprising a metallic material and coupled to the second end of the liquefier tube, the extrusion tip having a cavity having an interior shoulder wherein the cavity terminates in an opening. The liquefier includes a hardened insert compositionally comprising a material that is harder than the metallic material of the extrusion tip and the metallic material of the liquefier tube. The hardened insert has an exterior shoulder that engages the interior shoulder of the extrusion tip such that the insert is press fit within the extrusion tip. The tip insert has a channel that aligns with the flow channel wherein the channel terminates at an extrusion port configured to extrude material therefrom. |
