Abstract: An additive manufacturing machine (910) includes a build unit (920) comprising a powder dispenser (906) including a hopper (1004) for receiving a volume of additive powder (1006). A powder supply system (1000) includes a powder supply source (1010) for providing additive powder (1006) into the hopper (1004) during a refill process. A powder reclamation system (1002) includes a vacuum pump (1030) coupled to a vacuum duct (1034, 1036) defining a suction inlet (1040) positioned for collecting misdirected additive powder (1006) dispensed during the refill process. A return duct (1038) includes a filter mechanism (1050) may filter and return the collected additive powder (1006) back to the powder supply source (1010) for reuse.
