Why manufacturers adopt additive manufacturing technologies: The role of sustainability

Emerging manufacturing technologies can affect the performance of manufacturing systems considerably. Hence, a proportionate and purposive choice of such technologies would significantly impact the success of a firm. Additive Manufacturing, a leading and impactful technology, is being implemented in many industrial sectors and for a variety of reasons. It presents huge potential benefits in terms of sustainability perspectives. This paper aims to identify and prioritize the determinants of its adoption as well as to clarify the role of sustainability benefits in the decision to adopt. Then, the research seeks to distinguish the priorities of different application sectors through a multi-stage survey. The results show that environmental sustainability benefits are barely relevant to adoption decisions in practice and this is in contrast with the literature stating the huge sustainability benefits. Moreover, the results prove the pivotal role of economic motives in adoption decisions. The findings also indicate that the capability of additive manufacturing for producing almost any complex design is the key driver of its adoption in all sectors.
