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.
