Sustainability in Additive Manufacturing

Book chapter, 2024

Additive manufacturing is positioned as a key enabler for sustainable production due to its inherent characteristics connected to near-net shape manufacturing, resulting in high material efficiency, as well as individualized and flexible manufacturing of complex 3D shaped objects on-demand. In addition, feedstock materials can be either reused in case of metal or sourced sustainably in case of renewable bio-based polymers. Further economic and social benefits can be realized along the supply chain and life cycle of the materials and products, depending on the selected technology, material, and application. This article provides an overview of additive manufacturing developments, their potential sustainability benefits and challenges along with concrete examples of different technologies and applications, and barriers to adoption.
