Summary: | A process including combining polystyrene and a first solvent to form a polystyrene solution; heating the polystyrene solution; adding a second solvent to the polystyrene solution with optional stirring whereby polystyrene microparticles are formed via microprecipitation; optionally, cooling the formed polystyrene microparticles in solution; and optionally, removing the first solvent and second solvent. A polystyrene microparticle formed by a microprecipitation process, wherein the polystyrene particle has a spherical morphology, a particle diameter of greater than about 10 micrometers, and a weight average molecular weight of from about 38,000 to about 200,000 Daltons. A method of selective laser sintering including providing polystyrene microparticles formed by a microprecipitation process; and exposing the microparticles to a laser to fuse the microparticles. |
