Additive Manufacturing of Ceramics and Complex Concrete Components: Techniques, Challenges and Applications in Construction

Abstract

Additive Manufacturing (AM), commonly known as 3D printing, is transforming the way materials and structural components are designed and fabricated in civil engineering and architecture. While polymer and metal AM technologies are widely explored, the application of AM in ceramics and concrete materials is emerging rapidly due to its ability to create complex geometries, reduce material waste, and enable customized construction components. Ceramics offer high temperature resistance, chemical stability, and durability, whereas concrete provides structural strength and versatility. This paper reviews the current progress in additive manufacturing of ceramics and complex concrete components, discussing techniques, material properties, printing technologies, challenges, and real-world applications. The study also presents comparative tables and conceptual figures to illustrate processes and performance. Finally, future trends such as hybrid printing, digital fabrication, and sustainable construction are discussed.
