The prosthetic socket is the primary component of a lower-limb prosthesis and must be replaced when the patient's stump size changes. This study aims to design an adjustable socket that can be adjusted to the required size without manufacturing a new socket. In this study, the model was developed in SolidWorks and analyzed numerically using ANSYS. A tensile and fatigue test was performed for the materials used in manufacturing the socket, as well as an F-Socket test on an amputated person to measure the interface pressure between the stump and the socket to be used as a boundary condition during the numerical analysis process. The results demonstrated key achievements: the model was designed to serve as an alternative to the traditional model, thereby reducing costs in socket manufacturing due to growth or changes in stump size. The results also indicated the feasibility of using carbon fiber filament as an alternative to polypropylene and of employing additive manufacturing instead of the currently expensive methods.
