With the increasing use of laser sintering as a form of Additive Manufacturing, there is considerable interest in developing new polymer materials for this technique. Due to the complexity of the process, however, materials have to fulfill very specific requirements in order to be easy processable. In this study, a screening methodology was developed that encompasses all material properties essential for laser sintering. This methodology consists of both traditional techniques to evaluate coalescence, melt flow and crystallization kinetics, as well as newly developed techniques to measure powder flow and crystallization shrinkage. Using this methodology, existing sinter materials such as polyamide-12 have been investigated, but also some new promising materials have been identified that could increase the material choice for laser sintering.
