Methods to rapidly optimize materials for Additive Manufacturing processes

ABSTRACT: The objective of this proposal is to build a foundation for the modeling of polymer powders for use in laser sintering (LS). These models will attempt to provide a basis for characterizing new LS material candidates, establishing a fundamental understanding of material behavior so that existing molding grade polymers can be adapted for use in LS, and qualifying LS feedstock for use in production. BENEFIT: Increased adaptation of LS grade polymers which should lead to decreased raw material costs, increased supply chain security, and broader mechanical properties. In addition, will potentially create a tool to help manage powder feedstock through recycling and mapping process parameters to measured powder quality.
