摘要： An additive manufacturing machine for repairing a component includes a build platform that supports the component and a powder dispensing assembly for selectively depositing additive powder over the build platform. A powder seal assembly includes a powder support plate positioned above the build platform and defining an aperture for receiving the component without contacting the component. An inflatable sealing element is operably coupled to the powder support plate around the aperture and is inflated to contact and seal against the component, thereby forming a support surface above the build platform upon which additive powder may be deposited.
