  • POWDER SUPPLY ASSEMBLY FOR ADDITIVE MANUFACTURING
    Publication number: 20240131595
    Abstract: A processing machine (10) for building an object (11) from powder (12) includes a build platform (26A); a powder supply assembly (18) that deposits the powder (12) onto the build platform (26A) to form a powder layer (13); and an energy system (22) that directs an energy beam (22D) at a portion of the powder (12) on the build platform (26A) to form a portion of the object (11). The powder supply assembly (18) can include (i) a powder container (640A) that retains the powder (12); (ii) a supply outlet (639) positioned over the build platform (26A); and (ii) a flow control assembly (642) that selectively controls the flow of the powder (12) from the supply outlet (639).

  • Explosive device comprising an explosive material having controlled explosive properties
    Patent number: 11673844
    Abstract: An explosive device is described herein, wherein the explosive device includes a substrate that has a surface, wherein surface energy of a portion of the surface of the substrate has been modified in a vacuum chamber from a first surface energy to a second surface energy. The explosive device additionally includes explosive material that has been deposited on the surface of the substrate in the vacuum chamber by way of physical vapor deposition (PVD), wherein the explosive material is deposited on the portion of the surface of the substrate subsequent to the surface energy of the portion of the surface of the substrate being modified from the first surface energy to the second surface energy.
