THERMOSET ADDITIVE MANUFACTURED ARTICLES INCORPORATING A PHASE CHANGE MATERIAL AND METHOD TO MAKE THEM
Publication/Patent Number: US2019248065A1 Publication Date: 2019-08-15 Application Number: 16/312,370 Filing Date: 2017-06-26 Inventor: Malvadkar, Niranjan   Dermody, Daniel L.   Sophiea, Daniel P.   Allen, Sharon   Solanki, Sanjay C.   Pyzik, Aleksander J.   Gorin, Craig F.   Assignee: Dow Global Technologies LLC   IPC: C08G18/12 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.

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.
