Methods of simulating additively manufacturing an object may include generating a simulated additively manufactured object based at least in part on a plurality of approximate consolidation domains that respectively correspond to a plurality of consolidation tracks determined from one or more digital representations of an additively manufactured object, and determining a predictive inference with respect to one or more material properties of the object to be additively manufactured based at least in part on the simulated additively manufactured object. Methods may include generating, for an object to be additively manufactured, a CAD file and/or a build file based at least in part on a simulated additively manufactured object and/or based at least in part on one or more predictive inferences with respect to one or more material properties of the object to be additively manufactured. An object may be additively manufactured based at least in part on a simulated additively manufactured object and/or a CAD file and/or the build file corresponding thereto.

Additive manufacturing simulations

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.
