Abstract Scope |
Ecological and economical demands are driving developments of sustainable solutions in the AM market, especially in the field of industrial applications. One open key point is the consideration of end-of-life scenarios for AM parts. This research evaluates recyclability of parts made from high temperature PAEK materials manufactured by laser sintering. In a first step, aging mechanisms of commercial PAEK materials in Powder Bed Fusion are evaluated. Secondly, parts made from carbon-fiber reinforced PEKK are micronized into powder and employed as feedstock for powder-based additive manufacturing. Basic part properties of laser sintered specimen produced with different content of recycled material are presented. Overall, technical feasibility of recycling of PAEK parts in powder bed fusion can be shown, whilst qualification for serial applications still has to be performed. |
