Abstract (EN): Since the very porous structure encourages cell growth, cellular materials based on triply periodic minimum surfaces (TPMS) are frequently used in bone scaffold applications. It has been demonstrated that the gyroid is more permeable than foams based on other TPMS. Additionally, it has been demonstrated that TPMS foams created using additive manufacturing technology can attain the required mechanical qualities to replace human bone. In this work, two sheet-based unit cells, the gyroid and the primitive structure where tested to determine the elastic and plastic properties. Scaling laws correlated well to experimental results found in the literature showing that the isotropic and perfectly-plastic approximations can model a wide range of materials namely metals and polymers. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.
