  • Spherical metallic powder blends and methods for manufacturing the same
    Patent number: 11130175
    Abstract: A method for manufacturing a spherical metallic powder blend using a metallic starting material, the method including steps of grinding the metallic starting material to yield an intermediate powder, spheroidizing the intermediate powder to yield a first spherical powder component, and mixing the first spherical powder component with a second spherical powder component, wherein the first spherical powder component and the second spherical powder component have substantially the same chemical composition.
    Type: Grant

  • METHODS FOR ADDITIVE MANUFACTURING WITH MASTICATED PARTICLES
    Publication number: 20200246870
    Abstract: A method of additively manufacturing a part is provided. The method includes flowing masticated particles through a deposition nozzle of a directed energy deposition additive manufacturing apparatus. Each particle of the masticated particles includes a surface formed by at least angular facets. The method also includes melting the masticated particles exiting the deposition nozzle with a directed energy source of the directed energy deposition additive manufacturing apparatus so as to form the part.
