  • Patent number: 10596726
    Abstract: An additive elastomeric manufactured part having an elongation at break of at least 50% may be made by a method comprising the following. A material comprising a prepolymer and filler is first dispensed through a nozzle to form an extrudate deposited on a base. The base, nozzle or combination thereof is moved while dispensing the material so that there is horizontal displacement between the base and nozzle in a predetermined pattern to form an initial layer of the material on the base. Subsequent layers are then formed on the initial layer by repeating the dispensing and movement on top of the initial layer and layers that follow.

    Abstract: An additive manufactured article is comprised of at least two adhered layers of extrudates (120) comprised of a thermoset material having therein a phase change material, wherein the phase change material undergoes a phase change at a temperature less than where the thermoset material decomposes. The article may be made by dispensing a mixture comprised of an organic reactive material and phase change material forming extrudates that are 3D printed into an article having multiple layers of extrudates bound together and then allowing the organic reactive material to react forming a thermoset material having therein the phase change material to form the additive manufactured article. The shape of the article may be changed by heating to a temperature above the temperature where the phase change material undergoes a phase change while applying a force and then cooling below the phase change temperature.

    Abstract: A porous inorganic additive manufactured article that is comprised of at least two layers of inorganic particulates bound together by a carbon binding phase throughout. The additive manufactured article may be formed by additive manufacturing using a mixture comprised of an organic reactive material and inorganic particulates, wherein the organic reactive material is subsequently reacted to form a thermoset material that forms carbon upon heating that binds the inorganic particulates together to form the porous inorganic additive manufactured article. The porous inorganic additive manufactured article may then be infiltrated with a liquid that is solidified to form a composite article or may be further heated in a differing atmosphere to form a further sintered or reacted porous inorganic article.

  • Publication number: 20190184628
    Abstract: An additive elastomeric manufactured part having improved surface finish is made by repeatedly extruding through a nozzle to build up layers of a material comprised of a prepolymer comprised of an isocyanate terminated prepolymer and a filler in an amount such that the material has a shear storage modulus G? of 100,000 to 300,000 Pa measured at an oscillation rate of 1 Hz and a relaxation time of 20 seconds to 360 seconds. It has been discovered that the particular material having these rheological properties is able to improve the surface finish of the additive manufactured part without slumping and is believed to be due to surface flow of material into valleys between the extrudates as they are being built up.

  • Patent number: 10201933
    Abstract: A three-dimensionally printed article is comprised of a hydroxyethyl methylcellulose (HEMC) having a DS of 1.7 to 2.5 and an MS of at least 0.5, wherein DS is the degree of substitution of methoxyl groups and MS is the molar substitution of hydroxyethoxyl groups. The HEMC may advantageously be used as a support material when making a three-dimensionally printed article using a build material such as a different thermoplastic polymer such as a poly(acrylonitrile-butadiene-styrene), polylactic acid, polyethylene and polyprophylene. When the HEMC is a support material it may be easily removed from the build material by contacting the three dimensionally printed article with water, which may be at ambient temperatures and a pH that is neutral or close to neutral.

  • Patent number: 10100168
    Abstract: The inventions is directed to a method for recovering support materials used in an additive manufacturing process. The method comprises exposing a precursor additive manufactured article comprised of a water soluble support polymer and an insoluble material to water. The water soluble support polymer is dissolved in the water. The remaining article is then removed from the water. The dissolved water soluble polymer is precipitated from the water. The precipitated polymer is separated from the water and any remaining water removed to recover the water soluble support polymer. The recovered water soluble support polymer may then be re-used to make further additive manufactured articles.

  • Patent number: 9764991
    Abstract: Porous aluminum-containing ceramic bodies are treated to form acicular mullite crystals onto the surfaces of their pores. The crystals are formed by contacting the body with a fluorine-containing gas or a source of both fluorine and silicon atoms to form fluorotopaz at the surface of the pores, and then decomposing the fluorotopaz to form acicular mullite crystals. This process allows the surface area of the ceramic body to be increased significantly while retaining the geometry (size, shape, general pore structure) of the starting body. The higher surface area makes the body more efficient as a particulate filter and also allows for easier introduction of catalytic materials.
