  • Systems and methods for depositing charged metal droplets onto a workpiece
    Patent number: 10589354
    Abstract: Apparatus and methods are described for performing additive manufacturing. The apparatus includes a vacuum chamber for fabricating a workpiece composed of deposited metal, a table positioned within the vacuum chamber, and configured to support fabrication of the workpiece on a substrate, and one or more multiple droplet emitters coupled to the vacuum chamber, and arranged to irradiate the workpiece with a stream of molten metal droplets during fabrication.
    Type: Grant

  • Reticulated Mesh Arrays and Dissimilar Array Monoliths by Additive Layered Manufacturing Using Electron and Laser Beam Melting
    Publication number: 20140336680
    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.
