Abstract: A method is provided for removing ultrafine particles from an atomized powder. The method includes contacting the atomized powder with a removal liquid, the atomized powder comprising fine particles and ultrafine particles, wherein contacting the atomized powder with the removal liquid comprises adding energy to a mixture of the atomized powder and the removal liquid to detach the ultrafine particles from the fine particles; and separating the removal liquid and ultrafine particles from the fine particles.

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.

Abstract: A method for removing ultrafine particles from an atomized powder includes contacting the atomized powder with a removal liquid to form a mixture of the atomized powder and the removal liquid, the atomized powder comprising fine particles and ultrafine particles, adding energy to the mixture of the atomized powder and the removal liquid with a liquid classifier system to detach the ultrafine particles from the fine particles, and separating, with the liquid classifier system, the removal liquid and the detached ultrafine particles from the fine particles.

Abstract: A sieving system for a powder is provided. The sieving system includes a support structure; a filter housing movable relative to the support structure, the filter housing defining an inlet and an outlet, the filter housing comprising a broad frequency filter disposed between the inlet and the outlet, the broad frequency filter configured to restrict a first portion of the powder larger than a predetermined threshold from reaching the outlet; and a powder mass control assembly configured to determine data indicative of a powder mass within a portion of the sieving system and control one or more operations of the sieving system based on the determined data indicative of the powder mass.
