Abstract
Polymer composites represent the industry standard in injection molding for the production
of plastic components with increased requirements in terms of heat resistance and stiffness. In the
field of laser sintering (LS), these materials are less common so far. In order to extend the available
material variety for the LS process, new ceramic-filled Polyamide 613 powders are investigated
within the scope of this work. Here, the resulting properties from two different powder production
methods are compared. One filled powder is produced by dry blending and the other powder with
the same filler and filling ratio is produced by encapsulating the filler particles inside the polymer
particles within the dissolution-precipitation process. It was found that encapsulating the filler
particles can provide certain benefits for the processability, for example an improved powder
flowability or better filler dispersion. However, encapsulating the filler also alters the thermal
properties of the precipitated powder.
