  • Patent number: 11548069
    Abstract: A 3D printer successively fuses sheet material in a stack to form a three-dimensional object. The sheet material may provide a mesh separating islands of material that will be fused to produce the desired three-dimensional object. The mesh provides support for the island material during the fusing process and may be removed afterwards.
    Type: Grant
    Filed: May 20, 2019
    Date of Patent: January 10, 2023
    Assignee: Wisconsin Alumni Research Foundation
    Inventors: Thomas Rockwell Mackie, Brandon Joseph Walker, Nathan Donald Schumacher
  • Publication number: 20220410275
    Abstract: High-throughput printing, possible with multiple electron beams, is facilitated by a continuous powder bed preparation process operating in parallel to apply and pre-sinter the powder along a continuous helical path. The sintered powder may be self-supporting to allow unconstrained expansion in the radial direction when high energy is used for powder fusion.

  • Patent number: 9981312
    Abstract: A 3-D printer scalable to large sizes employs a combination of mechanical and electrical scanning of a linear array of electron beams that operate to melt material of a powder bed. A housing holding the electron beam sources may be maintained at a high vacuum and positioned close to a print surface to minimize electron travel in a softer vacuum surrounding a print bed.
