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.

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: Control systems and methods for efficiently and effectively achieving and/or maintaining a parallel configuration between a build plate and a printing release surface of an additive manufacturing printer are provided. The methods include actions of over-plunging a drive point into a printing release surface and then calculating the build plate position until it achieves a desired target position. Other methods focus on a homing process for setting a zero position of the build plate. Structures used to help prevent build plate deflection include various armatures having a pinned configuration that help to stabilize a location of the build plate to maintain a substantially parallel configuration with respect to the printing release surface.

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: Systems and methods for combatting shrinking forces within drying photopolymers of additive manufacturing processes are disclosed herein. According to at least some embodiments, layers of an additive manufacturing build are split into core components and shell components. Magnetically active additives within the photopolymer resin are then aligned in a first plane while the core section is cured, and a second plane while the outer shell section is cured. According to at least some embodiments, the first plane and the second plane are perpendicular.
