چکیده مقاله
A number of different processing techniques have been developed to design three dimensional 3D scaffolds for tissue engineering applications These architectures can be obtained by means of refined methods and have to be assessed in terms of geometrical and mechanical properties Specifically, the triply periodic minimal surface TPMS is exploited to design a multi scale porous structure, which can achieve high mechanical behaviors with lightweight It was found that the TPMS method is an effective way to achieve gradients in multiple patterns which are comparable to natural tissue with respect to both continuous topology and interconnectivity Finite element analysis FEA is a mighty tool to recognize insertion process mechanics The purpose of this study was to improve mechanical strength of TPMS scaffolds, the Schwarz’s Primitive surface P surface , FEA results were evaluated against stress distribution at the TPMS interface were compared between different porosities FEA predicted higher stress values than those measured by more porosity
