摘要 Efective Selective Laser Melting(SLM)molding methods for femur implant design and molding can improve femur implant surgerysucess rates and enhance patients quality of life.In this study,an individualized femur implant and individualized biological fixed-typefenur implant were designed using the parametric modeling method.The implants were then directly manufactured via SLM moldingtechnology as the forming process was carefuly analyzed.The results indicate that the proposed implant allows for favorable conjunctionof the reconstructed implant model with the surrounding bone tissues under the premise of a relatively small amount of bone-cutting.Theproposed implant also shows even pore distribution,good overall connectivity,relatively high bearing capacity,favorable overlappingbetween supports,and strong inter-pore connectivity.Only a small amount of powder adheres onto the surface and can be directly usedafter simple sand blasting and polishing.The comprehensive analyses of fenur implant modeling and molding methods given in this papermay provide a sound foundation for the design and direct manufacture of individualized femur implants in the future.
