Large-scale 3D printed concrete structures with lattice infill will result in lightweight components high mass-specific strength, and faster fabrication, compared to conventional casting methods. However, the effect of different patterns on mechanical performance is still not addressed clearly many scientific publications. This study investigates bending 3D-printed beams four such as lattice, triangular, lattice-triangular, sinusoidal tested vertical (layer deposition direction) transverse translation loading directions. The load versus displacement curves crack propagation are investigated both via Finite Element (FE) simulations experiments. FE results corroborated by experiments indicated that triangular perform better than lattice-shaped counterparts particularly under direction exhibiting highest flexural deformation resistance capacity. findings this would be useful latticing large-scale for diverse applications.
