Changes in residual limb volume of transfemoral amputees significantly affect the fit, comfort, and stability of prosthetic sockets. These physiological changes often require continuous socket adjustments and represent a major clinical challenge in transfemoral prosthetic design. The aim of this study was to design a printable transfemoral prosthetic interface able to accommodate limb volume fluctuations by overcoming the limitations of current solutions through the development of a cost-effective, adaptable, and fast design strategy. The project was carried out at Snapform Startup based at the Technical University of Denmark (DTU). The proposed idea is an SLS-printable polyamide model with a single flexible component positioned posteriorly, which allows compression using the Click Medical Boa system.
