FILAMENT BASED ON A COMPOSITION INCLUDING FLUOROPOLYMER AND INORGANIC FILLER AND METHOD OF MAKING A THREE-DIMENSIONAL ARTICLE

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 s...

Zusammenfassung: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.
