Abstract: The method of making a three-dimensional article includes heating a composition comprising a fluoropolymer and inorganic filler, extruding the composition in molten form from an extrusion head to provide at least a portion of a first layer of the three-dimensional article, and extruding at least a second layer of the composition in molten form from the extrusion head onto at least the portion of the first layer to make at least a portion of the three-dimensional article. Three-dimensional articles are also described. A composition including a fluoropolymer and inorganic fillers is also described. The composition may be a filament. The composition can be useful, for example, in melt extrusion additive manufacturing. The fluoropolymer is semi-crystalline with a melting point of up to 325° C. and less than 50 percent by weight interpolymerized units of vinylidene fluoride or amorphous with a glass transition temperature of up to 280° C.

Abstract: Provided are methods of manufacturing hollow glass microspheres where a feed composition comprising a glass powder and a blowing agent entrained in the glass powder is introduced into an opening at a first end of a vertically-aligned furnace. Agglomerated glass, unmelted oxides, or natural glassy materials can be used in place of, or in addition to, the glass powder in the feed composition.

Abstract: A system and method for managing data used for manufacturing dental prostheses in a system having a plurality of scanning sites and a plurality of machining sites connected to at least one central unit. The central unit receives data from at least one of the scanning sites and assigns the data received from the scanning site to one of the machining site and transmits the assigned data to the machining site. The at least one scanning site and the plurality of machining sites are geographically remote from each other and from the central unit and at least one scanning site and the plurality of manufacturing sites are connected to the central unit via a telecommunication and/or computer network.
