AMORPHOUS THERMOPLASTIC ADDITIVE MANUFACTURED ARTICLES AND METHOD TO MAKE THEM
This abstract first appeared for US patent application 20240254327 titled 'AMORPHOUS THERMOPLASTIC ADDITIVE MANUFACTURED ARTICLES AND METHOD TO MAKE THEM
Original Abstract Submitted
a semi-crystalline blended polymer useful for additive manufacturing is comprised of an amorphous thermoplastic polymer and a thermoplastic semi-crystalline polymer, each of the polymers being essentially miscible in the other and being blended at a weight ratio of amorphous polymer/semi-crystalline polymer of greater that 1 to about 20. the semi-crystalline blended polymer displays a dsc melt peak enthalpy of at least about 3 joules/g. the semi-crystalline polymer may be made by blending the aforementioned polymers at the weight ratio and subject to heating between the melt temperature of the semi-crystalline polymer and the glass transition temperature of the amorphous polymer. the semi-crystalline blended polymer may revert to essentially an amorphous polymer when additive manufactured by fusing layers of said polymer powders together.
