Abstract: Systems may reduce fugitive particles of powdered build materials in additive manufacturing by including a shroud positioned over a powder spreading roller, wherein the shroud forms a passageway to transport the fugitive particles. The bottom of the shroud forms a horizontally elongate opening to fit over an upper circumferential portion of the roller, leaving a lower circumferential portion extending out therefrom. The shroud may also be connected to a fan, blower, or other suction source to transport fugitive particles along a passageway, through a filter, and into a bin for collection or potential recycling. The system may include a brush or scraper positioned in the shroud and which contacts the spreading roller to help physically remove any fugitive particles that might be stuck to the roller.
