Abstract
Official abstract text for this publication.
A method for wetting volatile material positioned on a filter from an additive manufacturing process includes passing a passivation fluid to an interior space of a filtration system including an outer housing, a filtration medium, detecting an amount of passivation fluid passed to the interior space with a volume detection device, determining whether the amount of passivation fluid passed to the interior space is less than a configurable threshold, in response to determining that the amount of passivation fluid passed to the interior space is less than the configurable threshold, continuing to pass the passivation fluid to the interior space, and in response to determining that the amount of passivation fluid passed to the interior space is not less than the configurable threshold, stopping the passing of passivation fluid to the interior space.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for wetting volatile material positioned on a filter from an additive manufacturing process, the method comprising: passing a passivation fluid to an interior space of a filtration system comprising an outer housing, a filtration medium structurally configured to filter gas passed from a dirty side of the filtration medium to a clean side of the filtration medium, wherein the interior space is defined at least in part by the outer housing and the dirty side of the filtration medium; detecting an amount of passivation fluid passed to the interior space with a volume detection device; determining whether the amount of passivation fluid passed to the interior space is less than a configurable threshold; in response to determining that the amount of passivation fluid passed to the interior space is less than the configurable threshold, continuing to pass the passivation fluid to the interior space; and in response to determining that the amount of passivation fluid passed to the interior space is not less than the configurable threshold, stopping the passing of passivation fluid to the interior space, wherein the configurable threshold is determined by an amount of passivation fluid to fill the interior space and an inner chamber volume defined by the filtration medium. 2. The method of claim 1 , wherein continuing to pass the passivation fluid to the interior space comprises maintaining a valve in communication with the interior space in an open position. 3. The method of claim 1 , wherein stopping the passing of passivation fluid to the interior space comprises moving a valve in communication with the interior space into a closed position. 4. The method of claim 1 , further comprising venting a gas from the filtration system to a location exterior to a building. 5. The method of claim 1 , wherein the passivation fluid comprises water. 6. The method of claim 1 , wherein the dirty side of the filtration medium comprises a volatile powder. 7. The method of claim 1 , wherein: the dirty side of the filtration medium comprises a volatile powder; continuing to pass the passivation fluid to the interior space comprises maintaining a valve in communication with the interior space in an open position; and stopping the passing of the passivation fluid to the interior space comprises moving the valve in communication with the interior space into a closed position. 8. The method of claim 1 , wherein the filtration medium is cylindrically-shaped and wherein the dirty side is positioned on an outer perimeter of the filtration medium.
