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 60° C. as measured by DSC and a minimum crystallization half-time of greater than 100 minutes as measured by SALS. A semi-crystalline polymer useful in additive manufacturing applications, an additive manufacturing method for producing a three-dimensional object and an additive-manufactured polymer article are also described.
