Abstract: A solid state beam routing apparatus includes a controller and a spatial angular light valve arranged to direct a two-dimensional patterned light beam through a predetermined angle in response to an applied voltage. A bed is arranged to receive the two-dimensional patterned light beam as a succession of tiles. In some embodiments, one or more solid state galvo mechanisms are used to direct the two-dimensional patterned light beams formed by the light valve to the multiple powder bed chambers.
