Abstract: The present invention relates to granular composite density enhancement, and related methods and compositions. The application where the properties are valuable include but are not limited to: 1) additive manufacturing (“3D printing”) involving metallic, ceramic, cermet, polymer, plastic, or other dry or solvent-suspended powders or gels, 2) concrete materials, 3) solid propellant materials, 4) cermet materials, 5) granular armors, 6) glass-metal and glass-plastic mixtures, and 7) ceramics comprising (or manufactured using) granular composites.

Abstract: The invention encompasses compositions and methods for designing or producing three-dimensional articles layer-by-layer, whereby the specific approach to build-up a region of a single layer by fusion, deposition of material, or other path-based process or non-path process that creates track-like geometries requires either differing track or track-like geometry, or track or track-like geometry printing parameters, within a region of a single layer or within adjoining regions of multiple layers, is disclosed. Employing this method, single layer or multilayer parameter-varying fusing and deposition strategies can be generated that reduce article fabrication time and improve article physical properties, in part by targeting a distribution of scan paths that satisfy covering problem overlap and/or dense packing criteria.
