  • Patent number: 11833757
    Abstract: A three-dimensional (3D) printing system for manufacturing a 3D article includes a resin vessel, a build tray, a movement mechanism, a light engine, a housing, a gas handling system, and a controller. The resin vessel includes a transparent sheet on a lower side. The housing defines two chambers including an upper chamber and a lower chamber. The upper chamber is in fluidic communication with the resin contained by the resin vessel. The lower chamber is in fluid communication with a lower surface of the transparent sheet. The controller is configured to (a) operate the gas handling system to reduce and control a partial pressure of oxygen in the upper and lower chambers, (b) operate the movement mechanism and the light engine to form the 3D article in a layer-by-layer manner.

  • Publication number: 20230331974
    Abstract: Polymerizable liquids are described herein which, in some embodiments, can produce 3D printed articles of high resolution and desirable mechanical properties. In one aspect, a polymerizable liquid comprises an acrylate component, a polymeric additive, and a monomeric curing agent, wherein the acrylate component and monomeric curing agent are copolymerizable upon exposure to light. In being copolymerizable, the acrylate component and monomeric curing agent can form a copolymer. As described father herein, the monomeric curing agent can enable further reaction of the copolymer with one or more crosslinking species to link the copolymer with one more polymeric networks.

  • Patent number: 10946307
    Abstract: An example method for extracting phytochemical oil from plant parts includes freezing plant parts from at least one of Cannabis sativa, Curcuma longa, Panax ginseng, and Panax quinquefolius. The frozen plant parts are reduced to a plant powder, which is suspended in an aqueous buffer. The aqueous buffer containing the suspended plant powder is incubated with at least one pectinase and at least one cellulase. An aqueous phase of the incubated aqueous buffer is evaporated through steam heating to obtain a steam dried product. Phytochemical oil, which includes at least one of cannabinoids, curcuminoids, and ginsenosides, is extracted from the steam dried product.
