The opening of new fields of application of powder-based additive manufacturing methods like selective
laser beam melting of polymers currently is hindered by the limited availability of materials showing good
processability. So far, virtually only polyamides are available as optimized powder materials. Two innovative
methods for production of spherical polymer micro particles for selective laser melting are discussed: The first
approach, stirred media milling and rounding, is applicable for a variety of polymers. It will be exemplarily
discussed for polyesters and the dependency of product properties (particle size distribution, shape,
crystallinity) on the process parameters in the comminution and in the rounding step will be assessed. The
second method, melt emulsification, will be demonstrated for polypropylene. Moreover, the possibilities of dry
coating to tailor particle properties are illustrated. The influence of powder properties on the processability and
on the quality of the obtained devices is outlined.
