Abstract
Provided are compositions comprising partially crystalline polycarbonate particulate having an average cross-sectional dimension of from about 1 μιη to about 200 μιτι, having from about 10% crystallinity to about 50% crystallinity, and having a weight-average molecular weight, per polystyrene standards, of from about 17,000 to about 40,000 Daltons. The composition exhibits a zero-shear viscosity of less than about 104 Pa s at the melting temperature of the partially crystalline polycarbonate. Related systems and methods for utilizing these compositions in additive manufacturing applications, including selective laser sintering (SLS) applications, are also disclosed. Also provided are additively-manufactured articles made with the disclosed compositions and according to the disclosed methods.
