Abstract: A method of altering an additively manufactured part can include orienting a surface of the additively manufactured part toward a rotational center that may be independent of a rotational axis defined by the additively manufactured part, flowing an abrasive media past the surface, rotating the additively manufacturing part about the rotational center; urging abrasive particles in the abrasive media past the surface abrasive media to impinge the surface with centrifugal force generated by the rotating, and improving surface finish of the surface.

Abstract: An inspection method include introducing a mixture of expanding foam and a particulate material into a region of interest of an object, fixing the powder within the region of the interest relative to the object, and acquiring image data of the object and particulate mixture using an x-ray source and an x-ray detector. The particulate has a density that is greater than the density of a material forming the object to provide contrast between the region of interest and the object in an image generated using the image data.
