Abstract
Several grades of unreinforced and short fiber reinforced poly(ether ketone ketone) (PEKK) copolymers are analyzed for their potential use as feedstock materials in melt extrusion-based additive manufacturing (AM) systems. Rheological characterization has been performed to study the effect of extrusion processing parameters such as time, temperature, environment, and shear rate for the selected materials. The effect of reinforcing filler content on the melt processing conditions of PEKK composites are also reported, and processing conditions for successful extrusion of these materials on AM systems are determined.
