STUDY ON MECHANICAL PROPERTIES OF POROUS STRUCTURES BASED ON TPMS
In order to explore the influence of different TPMS pore structures on the mechanical properties of the porous scaffold, TPMS expressed by implicit function was used as the basic pore unit to construct the micro-porous structure. TPMS porous scaffolds with different structural characteristics were constructed by defining the distance function, And AlSi10 Mg porous scaffolds were prepared by SLM. Finite element Method（FEM） analysis and mechanical test method were used to study the influence of different pore structure characteristics on mechanical performance of porous TPMS scaffolds and analyze the influence law of different distance function k values on porosity, elastic modulus, yield strength and failure of Primitive（P） and F-RD porous structure scaffolds. Finite element analysis and experimental results show that with the increase of distance function k, the elastic modulus and yield strength of the P unit porous scaffold presented an increasing trend, However, the elastic modulus and yield strength of the FRD unit porous scaffold showed a downward trend, Moreover, Comparing to FRD unit, P unit porous scaffolds were more likely to be crushing, through the control of the TPMS types and the distance function k value, the porosity, elastic modulus and yield strength of the porous scaffold can be effectively adjusted. The results provide a basis for the design of tissue-engineered bone scaffolds.
