摘要:
A particulate material useful for additive manufacturing contains a semicrystalline polycarbonate or a semicrystalline polyetherimide. The particles of the particulate material are characterized by a narrow volume-based distribution of equivalent spherical diameters in which the median equivalent spherical diameter (Dv50) M is in the range 35 to 85 micrometers, the equivalent spherical diameter corresponding to 1 percent of the cumulative undersize distribution (DvO1) is greater than 2 micrometers, and the equivalent spherical diameter corresponding to 99 percent of the cumulative undersize distribution (Dv99) is less than 115 micrometers. Also described is a method of additive manufacturing utilizing the particulate material.
