This study investigates the properties of structures with an ordered cellular internal configuration. Certain forms structure contribute to manifestation auxetic properties. In this study, a hexagonal hourglass cell shape was chosen. The samples were 3D-printed PLA and ABS filaments. panels subjected out-of-plane compression. Poisson ratio under compression −0.06 for −0.05 samples. Tension tests performed using two types samples: type 1 monolithic shoulders 2 shoulders. average tensile strength 0.482 ± 0.006 kN, whereas that 0.416 0.028 which 13.7% lower. elongation at failure in 35% higher than (1.85 0.14 mm 1.37 0.08 mm, respectively). deformation capacity may be explained by presence mesh over entire sample. Auxetic are useful numerous engineering fields. For civil purposes, blast-proof abilities such important. Thus, future research, it is planned create fine-grain concrete similar structure.
