Abstract: Three-dimensional printing methods and systems use a derived geometry and aligns anisotropic inclusions in any orientation at any number of discrete volumetric sections. Structural, thermal, or geometry-based analyses are combined with inclusion alignment computations and print preparation methods and provided to 3D printers to produce composite material parts that meet demanding geometric needs as well as enhanced structural and thermal requirements. In one example, optimal inclusion alignment vectors associated with a section of the object are calculated based on specifications for the object, segmenting a three-dimensional model of the object into layer slices, grouping each section within each layer slice having similar alignment vectors and combining the groupings and generating printing instructions for the object according to the grouped alignment vectors.

Abstract: Methods for forming a coated digitally manufactured part include forming an article by a digital manufacturing method; coating a surface of the article with a reactive silicon-containing precursor polymer; and treating the polymer to form a silica-containing coating, thereby forming the coated digitally manufactured part. An article includes a digitally manufactured part having surface striations; and a coating encapsulating the digitally manufactured part and comprising silica. An article includes a digitally manufactured part (i) formed by selective lase sintering, (ii) comprising a surface defined by coalesced particles, and (iii) having a surface roughness Ra of at least 0.1 microns; and a coating encapsulating the part and comprising silica. A composition comprising polysilazane is described.

Abstract: Additive manufacturing apparatus and methods for mixing and dispensing materials, and articles with controlled particle concentrations. Additive manufacturing apparatus includes a mixer; a reservoir in fluidic communication with the mixer; and a build plate parallel to the reservoir. Additive manufacturing apparatus includes a mixer and a solid particle dispensing system and/or a slurry dispensing system. A method for handling precursors during additive manufacturing includes (a) providing first and second precursor materials and/or a slurry to a mixer; (b) mixing the materials in the mixer; (c) transporting the mixed materials directly to a reservoir disposed in parallel with a build plate; (d) curing at least a portion of the transported and mixed materials; and (e) repeating step (d) at least once. An article includes a plurality of adjacent layers, a concentration of particles in each layer defining a controlled concentration gradient and/or vary by no more than ±50%.

Abstract: Methods and systems for designing and manufacturing RF devices is provided. The disclosed methods allow for quick and efficient printing without having to generate a CAD file or the like to generate the build file. This can be achieved by receiving RF inputs, such as inputs generated from an RF simulation, and combining that with geometry design data, such as boundary geometry information that can include an outer geometry and size of the device to be printed. Further, the RF devices that are produced can use triply periodic minimal surface constructs as the base element of the device.
