Medical applications of rapid prototyping (RP) have an increasing trend, making the future of RP more and more promising. These applications may include design,development, and manufacture of medical devices and instrumentation, as well as implant design, anatomical models, surgical planning, surgical implants, and prosthesis fabrication. This paper will provide a new methodology in design of custom-made femoral stems that could provide optimal fill and fit for stems in individual femurs and result in optimize load transfer, minimize stem motion, increase initial stability and extend durability. Combinations of this methodology with RP technology can facilities manufacturing of custom-made femoral stem by considering time and economical aspects..
