The 3D concrete printing has been developed as one of the digitized technologies for the construction industry aiming to cope with some drawbacks of conventional construction methods. One of the main particularities of 3D printed cement based materials is its anisotropic/orthotropic behaviour, which is related to the layer wised approach of these addictive manufacturing processes. In this work, a cement based composition reinforced with polyvinyl alcohol fibre was used to evaluate the post-cracking behaviour of printed specimens in two different loading directions related to the layers’ orientation. Three-point bending tests were used to indirectly obtain the tensile behaviour (i.e. stress–crack width relationship) through an inverse analysis procedure. The results of inverse analysis showed that tri-linear relationship was able to accurately model the post-cracking behaviour of PVA-FRC specimens. No significant differences were observed on the tensile behaviour of 3D printed and mould cast specimens.
