An additive manufacturing device includes a table that supports an additive manufactured object, and a manufacturing unit including a first nozzle that is movable with respect to the table and a second nozzle that is movable with respect to the table and also movable with respect to the first nozzle. The manufacturing unit discharges powder from at least one of the first nozzle and the second nozzle, and emits an energy beam from at least one of the first nozzle and the second nozzle to melt or sinter the powder to additively manufacture the object supported on the table.

A molten metal feed pipe for feeding a molten metal of an nonferrous alloy includes an outer tube made of a ferrous material, an inner tube made of a molten metal resistant material, and an intermediate member made of a compact of a fibrous non-organic material, which is disposed between the outer tube and the inner tube. The intermediate member, positioned in the central region of the molten metal feed pipe with respect to the longitudinal axial direction of the molten metal feed pipe, is disposed between the outer tube and the inner tube with the intermediate member being compressed in a radial direction of the molten metal feed pipe.

On at least the edge portion () of the lip portion () of a T-die (), a cladding layer () is provided. The cladding layer is formed by laser build-up welding to a base material with a powder of a corrosion resistant and wear resistant alloy comprising a nickel-based alloy or a cobalt-based alloy. The cladding layer has a metallographic structure in which metal borides are dispersed in a binder phase. The lip portion has high quality and has high durability. The manufacturing costs of the T-die can also be kept relatively low.
