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: 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.
