Review of 3D printing technology for cementitious materials

3D printing is a helpful technology that demonstrates advances with all industries. However, it is still at the beginning of its development in the construction industry. The main objective of this thesis project is to review all the new advances presented today in this technology. The importance of every part that conforms 3D printing will be discussed here. This review analyzes the motors’ significance and the different configurations of printers exist today. This review presents the new advances in materials and improvements that these materials have along with the mixture. The mixture is the most crucial part of the 3D concrete printer because its composition affects its properties. In traditional construction, each material has a specific function on the building, how the properties can increase to an ideal range. However, in 3D concrete printing, every material affects all the properties, making it harder than conventional. Therefore, there should be more research about materials and how to improve them with new techniques, methodologies, and extrusion technologies. In 3D concrete printing, cement hydration and the thixotropic behavior of the material drive the extrusion system. Mechanical properties have crucial importance in construction. However, in 3D printing, there are techniques to enhance the reinforcement and all the mechanical properties.
