摘要: 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.

摘要: An additive elastomeric manufactured part is comprised of extrudates comprised of a reaction product of a multifunctional Michael donor and multifunctional Michael acceptor and a rheological modifier. The additive elastomeric manufactured part may have a high elongation and resistance to heat. Said part may be made by dispensing a mixture of the multifunctional Michael donor, multifunctional Michael acceptor, rheological modifier and a catalyst through a through a nozzle to form an extrudate deposited on a base. The base, nozzle or combination thereof is moved while dispensing the mixture 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.

摘要: 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.
