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.
