Selection of sustainable materials for additive manufacturing processes: a hybrid AHP-DEMATEL approach

Abstract

Additive manufacturing (AM) is vital to medical, aerospace, food, and automotive manufacture. AM makes complex products. Sustainable materials that enable cleaner manufacturing and reuse are essential in this fast-changing globalised environment. Polymers and nickel superalloys are employed in AM to meet these needs. This study uses an analytical hierarchy process (AHP) and decision-making trial evaluation and laboratory methodology (DEMATEL) to evaluate polymer laser sintering (PLS) and nickel-based superalloy for different AM procedures. DEMATEL’s findings will show a link between PLS criteria and nickel-based superalloys. This study conducts two case studies. AHP and DEMATEL techniques weight material cost as the most essential parameter for both case studies. In the PLS case study, polycarbonate is the most sustainable material, and based on weightage, INCONEL 718 is the most sustainable nickel-based superalloy. Two case studies will demonstrate criterion interdependence and score the material. The study’s findings can help AM technology material selection. Copyright © 2024 Inderscience Enterprises Ltd.
