  • Publication number: 20200131385
    Abstract: Provided is a method of producing polymer articles comprising (i) subjecting a composition to additive processing in an additive processing device containing at least one energy source wherein the composition comprises particles of a first polymer, particles of a second polymer and at least one binder material capable of binding the polymer particles to form a layer in a part of the composition that has been exposed to the energy source of the additive processing device; (ii) subjecting at least a part of the composition to exposure of the energy source to form a layer comprising the polymer particles and binder material; (iii) repeat step (ii) to form a plurality of layers to create an article; and wherein the first polymer is selected from polymers having a melting point above of at least 250° C. or a glass transition temperature (Tg) of greater than 70° C. and is not a fluoropolymer and wherein the second polymer is a fluoropolymer.

  • Publication number: 20190344496
    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.

  • Publication number: 20190329491
    Abstract: The method of making a three-dimensional article includes heating a composition comprising a polymer and hollow ceramic microspheres, 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 polymer and hollow ceramic microspheres is also described. The composition may be a filament. The polymer is at least one of a low-surface-energy polymer or polyolefin. The composition can be useful, for example, in melt extrusion additive manufacturing, for example, fused filament fabrication.
