Abstract

The escalating global housing crisis necessitates innovative solutions that streamline construction processes while enhancing sustainability and reducing costs. This paper explores the transformative potential of 3D printing technologies in the construction of affordable housing within the field of civil engineering. By examining the technical, economic, and environmental dimensions of 3D printed buildings, the study assesses their scalability for mass housing projects and discusses the significant advantages such as reduced waste, increased precision, and the utilization of recycled materials. The paper also highlights the major challenges to widespread adoption, including regulatory issues, material limitations, and workforce training needs. Through various international case studies, it demonstrates how 3D printing is being successfully implemented to address diverse housing needs and align with Sustainable Development Goals. The study concludes with strategic recommendations for overcoming existing barriers and maximizing the technology’s benefits, outlining a future where 3D printing could fundamentally alter the construction landscape.
