The transition toward sustainable energy and environmentally responsible technologies demands advanced manufacturing approaches that can enable high-performance, low-carbon, and resource-efficient solutions. Additive manufacturing (AM) plays a pivotal role in this transformation by fostering innovation across diverse domains, including renewable energy, hydrogen systems, environmental sustainability, electromechanical components, built environment applications, biomedical structures, polymer composites, and circular economy materials.

This Special Issue seeks to highlight cutting-edge research that advances AM materials, processes, and design methodologies to address global energy and environmental challenges. Contributions focusing on AM for renewable energy systems, environmental sustainability, advanced materials, polymer and bio-composites, electromechanical devices, electrochemical technologies, built environment solutions, and life cycle assessment (LCA) are particularly encouraged.

Interdisciplinary studies that bridge energy engineering, materials science, biomedical engineering, and the development of a sustainable built environment are highly welcomed.
