Abstract
3D cementitious material printing (3DCMP) is booming both in academy and industry over the last few years. The mechanical properties of structure fabricated by 3DCMP is limited compared to the conventional manufacturing method. The weak mechanical properties are attributed to the porosity formation within the products. Therefore, the numerical model developed for studying the single filament deformation is extended to evaluate the porosity formation within the multi-layer structure. Experimental results show the reliability of the numerical model. Then structure porosity with respect to the nozzle shape and relative nozzle travel speed are investigated. The results show that products porosity decreases with relative nozzle travel speed f for both the circular nozzle and rectangular nozzle.
