Abstract: A print engine of an additive manufacturing system includes a print station configured to hold a removable cartridge. A laser engine including a frame can be positioned to hold at least one removable field replaceable unit that includes at least some laser optics or patterning optics. An optical alignment system can be attached to at least one of the print station or the laser engine to align the field replaceable unit with respect to the removable cartridge.

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.

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.
