Water cure methods for producing three-dimensional objects from materials having multiple mechanisms of hardening
A method of forming a three-dimensional object (e.g. comprised of polyurethane, polyurea, or copolymer thereof) is carried out by: (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; (b) filling the build region with a polymerizable liquid, the polymerizable liquid comprising a mixture of: (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from the first component; (c) irradiating the build region with light through the optically transparent member to form a solid blocked polymer scaffold and advancing the carrier away from the build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, the three-dimensional object, with the intermediate containing the second solidifiable component; and then (d) contacting the three-dimensional intermediate to water to form the three-dimensional object.

Antifog polyester lidding film for CPET trays
The present disclosure is directed to peelable, heat-sealable lidding films for containers of diverse polymer compositions storing various products such as foodstuffs and pharmaceuticals. The lidding films disclosed herein can be heat-sealed to crystalline polyester trays (CPET), easily peeled, and contain improved antifogging performance by incorporating a non-migratory antifogging additive into the heat sealable layer of the film without deteriorating seal strengths.
POLYAMIDE HOT-MELT RESIN GRANULES LOADED WITH ACTIVE INGREDIENTS
The present document describes a polyamide hot-melt resin having a chemical structure consisting of dimerized fatty acids and diamines, loaded with an active ingredient. The dimerized fatty acids may have 12 to 24 carbons and the diamines may have 2 to 14 carbons. The amine residual functional groups and acid residual functional groups within the polyamide hot-melt resin may have a [NH.sub.2]/[COOH] molar ratio below 5, and the active ingredient may be incorporated in quantities of between about 0.01 and about 55% by weight of weight of the resin. The present document also describes items molded from the polyamide hot-melt resins, and processes of preparing the polyamide hot-melt resins.
