Patent No. 8,828,311

Description:
This patent consists of dry sonication that is utilized to remove unmelted powder following electron and laser beam melting processes using additive manufacturing.

Abstract:
Compositions and methods for making a three dimensional structure comprising: designing a three-dimensional structure; melting the three-dimensional structure from two or more layers of a metal powder with a high energy electron or laser beam is described herein. The position where the metal is melted into the structure is formed along a layer of metal powder, wherein the location and intensity of the beam that strikes the metal layer is based on the three-dimensional structure and is controlled and directed by a processor. The instant invention comprises a novel dry state sonication step for removing metal powder that is not melted from the three dimensional structure.
