This special issue aims to explore recent advancements in Large Format Additive Manufacturing (LFAM), a rapidly evolving technology transforming various industries. Contributions are invited on topics such as energy-material interactions, material behavior during deposition, microstructural evolution, and process-structure-property relationships. Research on defect formation, prevention, and residual stress development in large-scale printed parts is also encouraged. Manuscripts discussing the integration of LFAM with other manufacturing techniques, automation, and sustainability aspects are welcomed. Furthermore, studies on the types of materials used in LFAM, including metals, polymers, ceramics, and composite materials, are highly valued. The use of multimaterial deposition systems and hybrid materials in large-format applications is also of great interest.
