Sustainable Additive Manufacturing for Construction

Additive manufacturing (AM) has emerged as a transformative technology in the construction sector, enabling the automated fabrication of complex geometries with reduced material waste, labor demand, and construction time. In particular, 3D concrete, polymer, and metal printing, together with related digital fabrication techniques, have attracted growing attention for their potential to reshape conventional construction practices. However, the widespread adoption of AM in construction remains constrained by several critical challenges, including limited material performance, anisotropy induced by layer-by-layer deposition, weak interlayer bonding, insufficient structural reliability, and uncertainties in long-term durability. Moreover, the integration of AM with structural design principles, reinforcement strategies, and existing construction standards remains underdeveloped, particularly for load-bearing and large-scale applications. These challenges highlight the need for systematic investigations that link materials, manufacturing processes, and structural performance to facilitate the practical implementation of AM technologies.This Research Topic aims to bridge the gap between the promising potential of AM in construction and its practical application. Despite notable progress, challenges related to material performance, digital fabrication, structural evaluation, and sustainability continue to limit their wider adoption. This Topic welcomes contributions that build on recent advances in additively manufactured construction systems, including printable materials, intelligent and integrated fabrication processes, experimental and numerical studies on structural behavior, and sustainability assessment. By integrating experimental, numerical, and design-oriented research, this collection seeks to foster interdisciplinary collaboration and support the development of scalable, reliable, and sustainable AM solutions for construction and infrastructure.This Research Topic focuses on AM technologies for construction.
