Abstract This paper provides a comprehensive survey of current technological challenges and prospects for 3D printing technology with concrete applied to large-scale buildings. This innovative construction approach promises to revolutionize the shape of buildings with considerable time and cost savings but is still facing many technical and operational challenges. We gathered the knowledge of the most relevant and recent publications with our perception to address and discuss the main operational parameters, feasibility, and prospects for 3DPC technology. The paper is organized into five main categories: rheology of concrete for printing, effect of chemical admixtures, the role of reinforcements and inclusions, printing parameters and solutions for large-scale printers, and an analysis of economic and environmental aspects.
