Cover Story: Ti6Al4V lattices are used in porous scaffolds surgically implanted for the treatment of large bone defects to support the healing process. Functionally graded lattices mimic the features of the human bone, reducing stress shielding. The flexural properties of lattices remain underexplored. The aim of this study is to assess the flexural rigidity of a novel lattice material, namely Triply Arranged Octagonal Rings (TAOR). The effect of different cross-sectional geometries and relative density distributions was assessed, and the results were compared to those of a bone surrogate (BS) for long bones. The TAOR scaffold with its hollow cross-section and low relative density showed promising results by achieving a flexural rigidity close to that of the BS. The results of this study offer valuable insights into the design of porous bone implants. View this paper
