Abstract

The intersection of architectural engineering technology and digital fabrication is reshaping the future of construction. One of the most transformative advancements in this domain is 3D printing, also known as additive manufacturing. This paper explores how 3D printing is not merely an innovation in building materials and methods but a paradigm shift that is redefining the relationship between design and construction. Architectural engineering technology serves as the bridge that connects the creative potential of architectural design with the technical precision required in construction. 3D printing exemplifies this synergy by allowing complex geometries, customized components, and sustainable materials to be translated from digital blueprints to physical structures with unprecedented accuracy and efficiency. The paper begins by tracing the evolution of architectural engineering technology and its critical role in integrating design with construction workflows. It then delves into the core principles of 3D printing technologies, including extrusion, powder bonding, and photo polymerization, as applied in the construction sector. Case studies are presented, highlighting successful 3D-printed buildings and infrastructural components across different geographies, showcasing the technology's versatility and real-world applicability. The discussion further analyses the benefits of 3D printing in terms of cost reduction, time savings, material efficiency, and reduced environmental impact, as well as the challenges it poses, such as regulatory barriers, structural integrity concerns, and workforce adaptation. By synthesizing technical innovation with architectural vision, 3D printing is enabling more resilient, efficient, and sustainable building practices. This paper argues that architectural engineering technologists are uniquely positioned to lead this transformation by mastering the tools of digital fabrication and fostering interdisciplinary collaboration. As the construction industry grapples with global challenges urbanization, climate change, and resource scarcity 3D printing, empowered by architectural engineering, emerges as a pivotal force in building the future.
