Claim 9:
10. An additive manufacturing apparatus, comprising:
a nozzle body provided in a predetermined machining area and configured to discharge a mixture fluid of a powder and a carrier gas from an opening;
a gas storage storing the carrier gas;
a powder storage storing the powder;
a supply path that the mixture fluid flows, an upstream side of the supply path is connected to the gas storage and the powder storage and a downstream side of the supply path is connected to the nozzle body;
a bypass that branches from a branching point of the supply path and merges to a confluence point that is arranged at downstream side of the branching point in the supply path, the bypass is configured that a part of mixed gas that is a mixture of the carrier gas and the powder flows into from the supply path;
a flow rate adjuster configured to adjust a flow rate of the mixed gas that flows into the bypass from the branching point of the supply path;
a separator positioned in the bypass to receive the mixed gas that flows into the bypass, wherein the separator separates the mixed gas into separated powder and separated carrier gas and discharges the separated carrier gas to the confluence point for discharge from the nozzle body with the mixture fluid.
