Abstract
Optics assemblies and their methods of use in additive manufacturing systems are described. In some embodiments, an additive manufacturing system may include a build surface, a plurality of laser energy sources configured to produce a plurality of laser spots on the build surface, and an optics assembly configured to independently control a size of each of the plurality of laser spots and a spacing between the plurality of laser spots on the build surface. The optics assembly may include a plurality of lens arrays, where the plurality of lens arrays is configured to adjust a size of each of the plurality of laser spots on the build surface, and at least one lens. The at least one lens may also be configured to adjust a spacing between the plurality of laser spots on the build surface.
