Summary: | Provided are amorphous and at least partially crystalline polyetherimide compositions having a comparatively narrow particle size distribution and are particularly suited for additive manufacturing processes. The compositions comprise a population of polyetherimide particulates are characterized as having a zero-shear viscosity sufficiently low so as to achieve a coalescence of at least 0.5, and preferably of about 1.0, as characterized by the Frenkel model at a temperature less than 450° C. |
