Abstract

Three-dimensional technology is different from the traditional construction in process, which has many advantages like personal customization, reduced energy, rapid manufacturing. Therefore, to study the performance and test methods of 3D printing cement-based materials has significance effects on research and promotion of building three-dimensional technology. In this paper, addictive manufacturing and mould cast were used to manufacture samples. The results show that compressive strength of the printing samples is about 14 MPa at 1 day, 17 MPa at 3 days and 26 MPa at 7 days, which are about 55, 61 and 53% of the mould cast; the compressive strength of printing samples is anisotropy in the vertical and parallel directions for the printing direction, and the difference decreases with the flowbility increasing; the bonding layer gets weaker with the printing time increasing, especially at 10 min initially.
