Along two decades, wide research has been carried out within the characterisation of the mechanical properties of cellular or lattice structures made by additive manufacturing. Being one of the most complex geometries, lattice structures have been extensively studied in compression condition. However, tensile characterization is rarely addressed because of the difficulties related to the definition of a suitable design. The present study aims to expand the knowledge about these structures produced with metallic powders, evaluating their tensile behaviour. Two different customised lattices structures are designed. The specimen is designed according to the BS EN ISO 6892 ¿ 1 standard and using a graded geometry from full solid bulk to the lattice within the strain gauge length.
