  • ADDITIVE MANUFACTURE SYSTEM USING LIGHT VALVE DEVICE
    Publication number: 20230347591
    Abstract: An object build area is exposed to a radiation beam, such as a laser light source, which has been processed and controlled through a grating light valve or valves, or planar light valve, to thereby melt, sinter, fuse or cure predetermined portions of the build area corresponding to the equivalent of individually controlled pixels, with rapid movement and positioning of the resulting LV application output array on the build area. The LV arrangement is adapted to also generally heat an entire powder bed, or targeted areas of the bed, to just below melting temperature.
    Type: Application
    Filed: July 3, 2023
    Publication date: November 2, 2023
    Applicants: EOS of North America, Inc., AM Ventures Holding GmbH
    Inventors: Donald Lewis Vanelli, Lance Bruce Shanklin, Gregory Richard Hayes, Hakan Pfeiffer

  • Radiation source
    Patent number: 9192039
    Abstract: A radiation source having a nozzle configured to direct a stream of fuel droplets along a trajectory towards a plasma formation location, a laser configured to direct laser radiation at the fuel droplets at the plasma formation location to generate, in use, a radiation generating plasma. The nozzle has an internal surface that is configured to prevent contamination present in fuel used to form the fuel droplets from being deposited on that internal surface.
    Type: Grant
