  • Patent number: 11079683
    Abstract: An aperture system for a bottom-up stereolithography device including a reservoir having a lower opening, an aperture including a flexible membrane positioned within the reservoir and covering the lower opening, and a boundary seal positioned around a periphery of the flexible membrane, the boundary seal including one or more boundary seal components and immobilizing the periphery of the flexible membrane against the reservoir. The flexible membrane is formed of a material having a low affinity for a liquid resin used in the stereolithography device as well as cured photopolymer resin parts produced by the device. In addition, the flexible membrane is able to deform as the cured resin part is pulled away from the aperture, thus enabling lower energy mixed mode adhesive failure to occur at the interface between the cured resin and the aperture and reducing the chance of cohesive damage to the cured photopolymer part.

  • Patent number: 11053571
    Abstract: We have developed a scalable approach to directly incorporate grain-refining nanoparticles into conventional hot-tear-susceptible pure aluminum or aluminum alloy powders. These aluminum alloy powders may be additively manufactured into high-strength, crack-free aluminum alloys with fine equiaxed microstructures by incorporating nanoparticle nucleants to control solidification during additive manufacturing. Some variations provide an additively manufactured aluminum alloy comprising aluminum and at least one grain-refining element, wherein the additively manufactured aluminum alloy has a microstructure with equiaxed grains. Pure aluminum or aluminum alloys, combined with grain refiners, are useful in many processes beyond additive manufacturing. Some variations provide an aluminum alloy comprising aluminum and grain-refining nanoparticles selected from zirconium, tantalum, niobium, or titanium, wherein the aluminum alloy has a microstructure that is substantially crack-free with equiaxed grains.

  • Patent number: 11050075
    Abstract: In some variations, a hydrogen-storage material formulation comprises: a solid hydrogen-storage material containing at least one metal and hydrogen that is bonded with the metal; and a liquid electrolyte that is ionically conductive for at least one ion derived from the hydrogen-storage material. The liquid electrolyte may be from 5 wt % to about 20 wt % of the hydrogen-storage material formulation, for example. Many materials are possible for both the hydrogen-storage material as well as the liquid electrolyte. The hydrogen-storage material has a higher hydrogen evolution rate in the presence of the liquid electrolyte compared to a hydrogen-storage material without the liquid electrolyte. This is experimentally demonstrated with a destabilized metal hydride, MgH2/Si system, incorporating a LiI—KI—CsI ternary eutectic salt as the liquid electrolyte. Inclusion of the liquid electrolyte gives a ten-fold increase in H2 evolution rate at 250° C., reaching 3.5 wt % hydrogen released in only 7 hours.
