In this study, design of a conceptual semi-active transfemoral prothesis which can be used for walking, sit-to-stand and stair climbing was studied. In this study, human data in literature were analyzed and according to these data, firstly conceptual design of the prosthesis was presented. The first initial concept design was also built by means of 3D printer. Thereafter according to built model, the conceptual design was modified to make it more stable for functions. Also, the theoretical spring coefficients were calculated. According to structural parameters, FEM analyses of prosthesis were made. And parts on prosthesis were optimized by using topology optimization process.
