Classification: CPC B  Y | IPC B

Claim 0:
1. An additive manufacturing apparatus, comprising:
a nozzle body provided in a predetermined machining area and configured to discharge a powder and a carrier gas from an opening;
a powder supply having: a powder storage storing the powder; a gas storage storing the carrier gas; and a supply path connected to the nozzle body and leading to the opening of the nozzle body, the powder supply being configured to supply the powder stored in the powder storage and the carrier gas stored in the gas storage through the supply path;
a flow rate adjuster provided in the supply path of the powder supply and configured to cause a part of a flow of the carrier gas containing the powder to flow into a branch flow path branching from the supply path to adjust a flow rate of the carrier gas containing the powder to be supplied to the nozzle body; and
an upstream side of the branch flow path connected to the flow rate adjuster,
a downstream side of the branch flow path being connected, without going through the gas storage, to a confluence point on the supply path leading from the flow rate adjuster to the opening of the nozzle body between the flow rate adjuster and the nozzle body,
the branch flow path having a separator provided therein for separating the powder and the carrier gas, and
the additive manufacturing apparatus being configured such that the carrier gas separated from the powder by the separator is supplied to the nozzle body through the branch flow path connected to the separator.
