Abstract: The presently disclosed embodiments generally relate to reservoir manifold systems suitable for use with an additive manufacturing apparatus. Such manifold systems enable ease of use for making mechanical, electrical, and fluid connections to a reservoir used for additive manufacturing. Conduits formed in the reservoir manifold can allow for a fluid connection to be established with a reservoir to allow fluid flow into and out of the reservoir. The reservoir manifold can include one or more arms that are configured to move independently to couple to the reservoir of the printing apparatus. The reservoir manifold can include a trigger coupled to a latch mechanism for engaging one or more components of the apparatus. In some embodiments, the ability of the manifold to make electrical connections to the reservoir may present advantages to the ease-of-use and reliability of an additive manufacturing apparatus.

Abstract: Systems and methods for producing more accurate, intricate structures via digital light processing additive manufacturing are provided. One or more digital transformations, or filters, are applied to 2D-images used to print the part to help eliminate the effects of scatter. The digital transformations can lead to higher doses of light to be applied to edges and smaller features while limiting an amount of exposure to light of larger features to avoid over-curing of the larger features. This can help keep the integrity of certain designs, such as lattices and other structures that are intended to have some porosity. The digital transformations can also be used in a diagnostic manner to help provide feedback on performance.

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.

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: 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.
