The report covers the designing and fabrication of the prosthetic lower limb. The project specifications and requirements such as affordability, robustness and customizability of the prosthetic foot. The detailed literature review has been done to get the knowledge of several terms in prosthetics. This project concerns the design and manufacture of medical devices that require a high level of customization. We focus the attention on lower limb prosthesis and on the prosthetic foot. The proposed method is cantered on the modelling and manufacture of patient's residual limb. Three main phases can be identified: design, validation and manufacture of the prosthetics foot. Firstly, we use the computer aided design tool to design the prosthetics foot design. Then, a numerical simulation is run to check mechanical features and validate the prosthetics foot design. Finally, manufacturing and build prosthetics foot. Preliminary results are presented, and conclusions are drawn concerning the challenge of prosthetics foot. Aim: The aim of this priority area is the development of technologies for prosthetics, which meet the functional, environmental and economic factors of resource-constrained settings. Context: Physical disabilities such as a missing limb due to birth defect, disease or amputation have a severely negative effect on the affected individual's quality of life, welfare and potential for employment in many countries. There is a need for functional prosthetics, which are affordable, robust, reliable and fit for purpose. They need to be suitable for sustained use and easy to manufacture, maintain and/or repair.
