Abstract Scope |
High-strength, fully porous TPMS lattice structures built with additive manufacturing offers exciting potential. While their mechanical properties and morphological features have been intensely researched, their interplay remains unclear. This study explores a systematic methodology to understand the relationship between morphological parameters and the mechanical properties of TPMS lattice structures, focusing on gyroid unit cells. These structures were fabricated using the FFF additive manufacturing process with PEEK material. Morphological investigations were conducted using SEM to compare surface topography with the design. Mechanical properties were evaluated through compression testing and finite element analysis using the Johnson-Cook material model in ABAQUS software. The study provides insights into the effective mechanical properties of the lattice structures in both linear elastic and nonlinear plastic regions. These findings improve understanding of how morphological parameters influence mechanics, offering valuable information to recognize manufacturable design solutions. |
