In order to improve the behaviour of cementitious material under in bending, 3D printed polymeric lattice meshes were used as an alternative to fibre reinforcement. Lattice meshes with different cell sizes and different surface roughness were designed and printed. Plain mortar samples and reinforced samples were casted. After curing, 4-point bending tests were performed. The tests results show that, with the right designs, strain-hardening behaviour is achieved. Simultaneously, the flexural strength and flexural deflection capacity of mortar bars are increased. Crucial to this effect, a small mesh size (especially in the region of highest moment). Creating ridges on the reinforcement to increase the surface roughness of the reinforcement also showed promise in improving the deflection capacity and flexural strength.
