  • Light valve cooling system
    Patent number: 11969790
    Abstract: An additive manufacturing system includes a high power laser to form a laser beam directed against a light valve. An active light valve cooling system is arranged to remove heat from the light valve and a heat exchanger is connected to the active light valve cooling system. A heat exchange fluid is circulated through the active light valve cooling system and the heat exchanger.

  • Distributed Flux Array
    Publication number: 20240109252
    Abstract: An apparatus includes at least one laser source and a print bed. A light valve array having at least three optically addressable light valves is positioned to direct differing images at the print bed. Optics to direct multiple beams derived from the at least one laser source can be positioned to direct light toward and from the optically addressable light valves.
