In this paper, a series of polymer composites made from acrylonitrile-styrene-acrylate
(ASA) and poly (ether ether ketone) (PEEK) were manufactured. ASA acts as a polymer matrix
while PEEK is loaded in the form of micro-particles that act as a reinforcing filler. The composites
were compounded by single screw extrusion and then, different specimens were manufactured
either via injection moulding (IM) or fused filament fabrication (FFF). Two different types of PEEK
(commercial and reused) in different concentrations (3 and 6 wt.%) were tested and their influence in
the mechanical, structural, and thermal properties were studied. It was observed that reused PEEK
enhanced the stiffness and tensile strength and thermal stability of the composites both, for injected
and printed specimens. This evidences the suitability of these composites as potential candidates as
novel materials with enhanced properties following an approach of circular economy
