Abstract: In recent years, there have been significant breakthroughs in the development of 3D printing technology in the construction field. Its advantages of fast manufacturing speed, low cost, energy-saving, and environmental protection have attracted more attention. However, there are still flaws in the application of cementitious materials in 3D printing technology. The development of 3D printing materials is a key factor for the maturity of architectural 3D printing. In this paper, the Portland cement with limestone powder was selected as the research object, and the mix ratio suitable for 3D printing cement-based materials was designed. Workability and mechanical strength of the 3D printing cementitious materials with 5%, 10%, 15%, and 20% limestone powder were tested. Test results show that ordinary Portland cement mixed with an appropriate amount of limestone powder can be used as a high-quality 3D printing material. The experimental results show that an appropriate amount of limestone powder can be used to prepare 3D printing materials with excellent working and mechanical properties instead of ordinary Portland cement.
