Abstract: The present disclosure provides compositions, articles, and methods related to altering electromagnetic radiation. An actinic radiation curable precursor composition of a three-dimensional article includes a) a resin comprising an actinic radiation curable component, wherein the resin has a viscosity no greater than 500 cP; b) hollow glass microspheres having a density no greater than 2 g/mL and an average diameter no greater than 200 micrometers; and c) a photoinitiator. At least part of the surface of the hollow glass microspheres comprises a surface coating or modification. An article includes a photo(co)polymerization reaction product of the composition. A method of manufacturing a three-dimensional article includes the steps of a) providing an actinic radiation curable precursor composition; and b) selectively exposing a portion of the composition to a source of actinic radiation to at least partially cure the exposed portion of the composition, thereby forming a cured layer. Steps a) and b) are repeated so as to form a three-dimensional article. A three-dimensional article is provided, obtained according to the method. Methods of interfering with electromagnetic radiation originating from an electromagnetic radiation producing device are provided, including integrating an article into the electronic device or placing an article in the vicinity of the electromagnetic radiation producing device.

Abstract: A device for progressively building up an object from a light hardenable material. The device has a perforated build platform for the object. The build platform forms a build surface that faces a light source. The build platform and the light source are positionable relative to each other by computer control. The device is further configured for supplying the light hardenable material through the perforation of the build platform for building up the object. The invention enables the making of colored objects by stereolithography.

One method includes a) providing a photopolymerizable composition; b) selectively curing the photopolymerizable composition using actinic radiation to form an article in the shape of an orthodontic article having a plurality of layers of at least one photopolymerized polymer; and c) exposing the article to water by submersion in water, thereby hydrating the article. A sheet of the at least one photopolymerized polymer has a bending modulus when hydrated of 100 MPa or greater and 2200 MPa or less. Another method includes exposing the orthodontic article to water vapor and hermetically sealing the hydrated orthodontic article in a container. Hydrated orthodontic articles are also provided, including an orthodontic article that is prepared according to one of the methods. The present disclosure further provides kits, including an orthodontic article and instructions for exposing the orthodontic article to water to hydrate the orthodontic article, as well as including a hydrated orthodontic article hermetically sealed in a container.
