    Abstract: The present disclosure provides a photopolymerizable composition. The photopolymerizable composition includes a) 40-60 parts by weight of a monofunctional (meth)acrylate monomer, per 100 parts of the total photopolymerizable composition; b) a photoinitiator; and c) a polymerization reaction product of components. A cured homopolymer of the monofunctional (meth)acrylate monomer has a glass transition temperature of 125 degrees Celsius or greater. The polymerization reaction product of components includes i) a diisocyanate; ii) a hydroxy functional methacrylate; iii) a polycarbonate diol; and iv) a catalyst. The polymerization reaction product includes a polyurethane methacrylate polymer. Often, the polycarbonate diol has a number average molecular weight of greater than 1,000 grams per mole (g/mol) or a weighted average of all polycarbonate diols present in the components has a Mn of greater than 1,000 g/mol; alternatively, the polyurethane methacrylate polymer has a weight average molecular weight of 8,000 g/mol or greater. An article is also provided including the photopolymerizable composition reaction product. Further, the present disclosure provides articles and methods of making articles. Methods are additionally provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is also provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article.

    Abstract: An optical system comprises a lightguide having an elongated recess formed therein. The recess divides the lightguide into a first lightguide section a second larger lightguide section. Light extractors are disposed in the second, but not the first, lightguide section for extracting light that would otherwise propagate within and along the second lightguide section via total internal reflection (TIR). The depth of the recess varies along its length. The inclusion of a recess having a depth that varies along its length provides design flexibility in the number and location of light source(s) used by the optical system.
