| description | A liquefier nozzle 1 for an additive manufacturing system, such as fused deposition modelling, includes a body 2 formed of a first, thermally conductive material and an insert 3 formed of a second, wear resistant material. The body has a connecting feature 20 for connecting the nozzle to a heater of a liquefier assembly, a receptacle 26 having a substantially constant cross-section extending from a mouth 23 at a downstream end of the body and a filament passageway 25 extending from an upstream end to the receptacle and having a smaller diameter than the receptacle. The insert has a filament passageway 35 extending from an upstream end of the insert to a smaller diameter outlet 36 at a downstream end of the insert with a tapered transition 37. The insert is press-fit into an interference engagement within the receptacle of the body. Preferably, the first material comprises a copper alloy and the second material comprises steel. A coating may be applied to the downstream end of the insert; the coating may be harder than each of the first and second material, the coating may comprise a modified chemical composition to reduce adhesion of molten plastic thereto, the coating may comprise a diamond-like carbon coating. A method of manufacturing a liquefier nozzle comprising press fitting the insert into the body is further provided. |
