Additively manufactured impeller

摘要

An impeller (40) including a blade section (52), a shroud section (46), and a hub (54) is made of a monolithic structure. The impeller (40) is made by loading a 3D image file into an additive manufacturing device, using it to generate 2D files which correspond to a plurality of cross-sectional layers of the impeller, and solidifying corresponding portions of pulverant material layers to create the impeller (40).
