    Abstract: The present disclosure provides a composite material. The composite material includes 20 to 40 weight percent (wt.%) of a polymerizable component; 6 to 40 wt.% of ceramic fibers; and 30 to 70 wt.% of nanoclusters. Each of the ceramic fibers has a diameter and a length, the ceramic fibers having an arithmetic mean diameter of 0.3 micrometers to 5 micrometers, and the length of fifty percent of the ceramic fibers (based on a total number of the ceramic fibers) is at least 10 micrometers and the length of ninety percent of the ceramic fibers is no greater than 500 micrometers. The present disclosure also provides a method of making the composite material. The method includes obtaining components and admixing the components to form a composite material. Further, the present disclosure provides a method of using a composite material including placing a composite material near or on a tooth surface, changing the shape of the composite material near or on a tooth surface, and hardening the composite material. In addition, the present disclosure provides dental products and kits. Hardened composite materials can exhibit high strength.

    Abstract: The present disclosure provides a method of making an additive manufactured article. The method includes: a) attaching a multilayer structure (300, 500) to a build platform (210); b) selectively curing a photocurable composition (219) that is in contact with a porous layer (330, 530) of the multilayer structure, thereby forming an object attached to the porous layer; and c) separating the object from the build platform. The multilayer structure includes an adhesive layer (310, 510), an impermeable layer (320, 520) attached to the adhesive layer, and a porous layer (330, 530) attached to the impermeable layer. The adhesive layer of the multilayer structure is attached to the build platform. The present disclosure also provides an object made by the method, and the multilayer article used in the method. Use of the multilayer article assists in improving adhesion between the build platform and the object.

    Abstract: The present disclosure provides a multiphoton imaging method. The method includes a) immersing a semi-submersible microscope objective in a liquid medium that is at least one of scattering or absorbing; b) directing laser light through the semi-submersible microscope objective and into the liquid medium in an image-wise manner under conditions such that multiphoton absorption by the multiphoton absorber occurs, and at least partial polymerization of the polymerizable compound occurs resulting in an article; and c) removing uncured polymerizable compound to clean the article. The liquid medium includes a polymerizable compound, a secondary component, and a multiphoton absorber. An article is also provided. The article includes a material defining one or more tortuous or arcuate channels, one or more internal architectural voids, one or more undercuts, one or more perforations, or combinations thereof, at least one of which exhibits a surface roughness of 1.0 micrometer Ra or less.

    Abstract: The present disclosure provides a method of making a non-oxide ceramic part. The method includes obtaining a photopolymerizable slurry; selectively curing the photopolymerizable slurry to obtain a gelled article; drying the gelled article to form an aerogel article or a xerogel article; heat treating the aerogel article or the xerogel article to form a porous ceramic article; and sintering the porous ceramic article to obtain a sintered ceramic article. The photopolymerizable slurry includes non-oxide ceramic particles; at least one radiation curable monomer; a solvent; a photoinitiator; an inhibitor; and at least one sintering aid. Further, aerogels, xerogels, porous ceramic articles, and non-oxide ceramic articles are provided. In addition, methods are 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.
