Abstract
A build material for additive manufacturing applications is disclosed. The build material includes a build composition in powder form, The build composition includes a semi-crystalline polymer having a glass transition temperature of at least 70° C. and an onset melting temperature of at least 125° C., as measured by DSC, and that exhibits an amorphous return. A semi-crystalline polymer useful in additive manufacturing applications and a method for making the semi-crystalline polymer article are also described.
