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. Likewise, the original shape may be returned by merely heating above the phase change temperature and then cooling in the absence of a force being applied.

Abstract: Recovery times and/or airflow of flexible polyurethane foam is increased by including certain tackifiers in the foam formulation. The tackifiers are characterized in being incompatible with polyol or polyol mixture used to make the foam, having a viscosity of at least 5,000 centipoise at 25 #C and having a glass transition temperature of at most 20 #C. The tackifier is pre-blended with certain monols to form a lower-viscosity blend that is combined with one or more other polyols and a polyisocyanate to form a reaction mixture for producing a polyurethane foam.

Abstract: A method of selective sintering additive manufacturing comprises employing a powder comprising composite particulates comprising a first thermoplastic polymer and a second thermoplastic polymer interspersed with each other. In a particular embodiment, the first thermoplastic polymer and second thermoplastic polymer have differing absorbance of the irradiation used to sinter the particles when performing the additive manufacturing method. The first and second thermoplastic polymer may be continuously intertwined in within the particles or one of the polymers may be a discontinuously dispersed in a continuous matrix of the other polymer.
