Abstract
A method for producing polysulfone micro-particles for 3D printing disclosed. For example, the method includes creating a mixture of polysulfone by dissolving polysulfone in an organic solvent, creating an aqueous solution of a polymeric stabilizer or a surfactant, adding the mixture of polysulfone to the aqueous solution to create a polysulfone solution, and processing the polysulfone solution to obtain polysulfone micro-particles having a desired particle size, a desired particle size distribution, and a desired shape.
