Abstract: An apparatus with first and second transparent conductive oxide layers is described. A photoconductive layer can be positioned between the first and a second transparent conductive oxide layers. The photoconductive layer can be a crystalline layer that can include bismuth silicate or other suitable materials. An electro-optical layer is positioned in contact with the photoconductive layer. In some embodiments the photoconductive layer is positionable to receive a write beam that defines a two-dimensional spatial pattern.

Abstract: A method of additive manufacture is disclosed. The method can include providing an enclosure surrounding a powder bed and having an atmosphere including helium gas. A high flux laser beam is directed at a defined two dimensional region of the powder bed. Powder is melted and fused within the defined two dimensional region, with less than 50% by weight of the powder particles being displaced into any defined two dimensional region that shares an edge or corner with the defined two dimensional region where powder melting and fusing occurs.

Abstract: A print engine of an additive manufacturing system includes a print station configured to hold a removable cartridge containing powder. A laser engine is positioned to direct a one or two dimensional patterned laser beam into the removable cartridge. In some embodiments powder is produced at least in part with a magnetohydrodynamic system.

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.
