Abstract: A powder reclamation system for reclaiming a metal powder from a metal powder processing device is provided. The powder reclamation system includes a filter housing defining an inlet and an outlet; a filtered reclaimed powder hopper in communication with the outlet of the filter housing for receiving a filtered reclaimed powder; a powder recirculation passageway configured for providing a flow of powder to a metal powder processing device, the powder recirculation passageway in flow communication with the filtered reclaimed powder hopper; a virgin powder hopper containing a virgin powder also in communication with the powder recirculation passageway; and a controller operable with the powder reclamation system for providing a mixture of the filtered reclaimed powder and the virgin powder through the powder recirculation passageway.

Abstract: A powder sieving system that is configured as part of a powder reclamation system is provided. The powder sieving system includes a support structure; and a filter housing movable relative to the support structure, the filter housing defining an inlet and an outlet and comprising a broad frequency filter disposed between the inlet and the outlet, the broad frequency filter including: a first filter fixed relative to the filter housing, the first filter being substantially rigid; and a second filter coupled within the filter housing adjacent to the first filter, the second filter being substantially flexible such that the second filter is movable relative to the first filter within the filter housing when the filter housing moves relative to the support structure, the first filter and the second filter configured to restrict a first portion of a powder larger than a predetermined threshold from reaching the outlet.
