Abstract: Provided is a technique for fabricating a powder material bedded in advance using a DED nozzle. According to one embodiment, there is provided an AM apparatus for manufacturing a fabricated object. The AM apparatus includes a DED nozzle. The DED nozzle includes: a DED nozzle main body; a laser port disposed at a distal end of the DED nozzle main body and for emitting a laser beam, and a laser passage configured to communicate with the laser port and for allowing the laser beam to pass through the DED nozzle main body; and a powder port disposed at the distal end of the DED nozzle main body and for emitting a powder material, and a powder passage configured to communicate with the powder port and for allowing the powder material to pass through the DED nozzle main body. The AM apparatus further includes a cover configured to surround a peripheral area of the laser port and the powder port of the DED nozzle. The cover is configured to have an opened downstream side in an emission direction of the laser beam.
