Abstract

Gradient Ti6A14V porous scaffolds were designed based on triply periodic minimal sur-faces(TPMS) and were fabricated by SLM technology. The effects of edge porosity P_out, center porosity P_in and average porosity P̄ on mechanics properties and energy absorption were analyzed. The results show that elastic modulus, compressive strength and total absorbed energy per unit volume W of gradient porous scaffolds with the same P all decrease with the increase of P_out and increase with the increase of P_in. The elastic v modulus, compressive strength and W of gradient porous scaffolds with the different P all decrease with the increase of P̄. P̄ has greater v influence on elastic modulus, compressive strength and W_v than P_in and P_out. The printed gradient porous scaffolds meet the requirements of elastic modulus and compressive strength of femur and tibia. The mechanics property model established may provide a reference for the applications of porous scaffolds in orthopedics.
