3D printing is finding increasing application in the building segment due to the growing demand for high performance and easily constructing complex designs. The 3D printing construction is used in various applications in the building industry. This technology helps in creating lightweight components such as walls and panels while maintaining structural integrity, lowering the handling & transportation costs. Chinese, Dutch, and Russian companies are some of the early adopters of 3D printed construction technology to construct buildings in Dubai, China, and the Netherlands.

The extrusion construction method dominated the 3D printing construction market due to the high demand for concrete material used in 3D printing in extrusion construction method in building, and infrastructure sectors. In this technique, the material is extruded from a nozzle mounted on a crane, gantry, or on a 6-axes robotic-arm to print a structure layer by layer. The extrusion-based technique is mainly employed for on-site construction applications and allows the usage of conventional construction materials such as concrete, geopolymer, cement, plaster, and clay.
