Abstract: Methods of manufacturing hardenable dental articles, packaged hardenable dental articles, and methods of packaging hardenable dental articles are disclosed. In various embodiments, the manufacturing may involve molding a hardenable dental material in a mold cavity that may be lined with a mold liner. The mold body may also form the package of the hardenable dental article formed within the mold cavity. In other embodiments, the hardenable dental articles may be provided in mold cavities located in sacrificial mold bodies that may be torn, stretched, softened, dissolved, etc. to release the hardenable dental articles in the mold cavities.

Abstract: A method of making a microstructured article such as barrier ribs for a display panel is described. The method employs a template to provide a discrete coating of a curable material.
Abstract: An optical subassembly is described comprising a stack of at least two optical films bonded with an adhesive having a relatively high initial peel strength. The peel strength is capable of being reduced upon exposure to radiant energy. Method of making an optical subassembly and display are also described. The backlight of the display may provide the radiant energy that reduces the peel strength of the adhesive.

Abstract: A curable slurry for forming ceramic microstructures on a substrate using a mold. The slurry is a mixture of a ceramic powder, a fugitive binder, and a diluent. The ceramic powder has a low softening temperature in a range of about 400° C. to 600° C. and a coefficient of thermal expansion closely matched to that of the substrate. The fugitive binder is capable of radiation curing, electron beam curing, or thermal curing. The diluent promotes release properties with the mold after curing the binder or quick and complete burn out of the binder during debinding.
