In order to investigate the influence of fabrication method on the uniaxial tensile and compressive properties of polyethylene (PE) reinforced engineered cementitious composites (ECC), the axial tensile and axial compressive stress-strain curves of cast-in-place ECC and 3D printed ECC were measured. The results show that the ultimate tensile strength of the printed specimen decreases slightly, while the tensile ductility greatly improves. The uniaxial compressive strength of ECC is not affected by mixing 6 mm and 12 mm PE fibers in ECC at a constant fiber volume content. The compressive strength of printed ECC is 60%-70% of that of cast-in-place ECC. The maximum compressive strength in z-direction and followed by x- and y-direction. The elastic modulus of printed specimen has a slight change. Moreover, the Poisson ratio in x- and y-directions is greater than that of cast-in-place ECC. A uniaxial compression stress-strain constitutive model suitable for cast-in-place ECC and printed ECC was established, and the accuracy of the model was verified by comparing with the measurement results. The model provides a theoretical basis for the calculation and analysis of 3D printed ECC components and structures.
