Abstract

Prosthetics help people with lifelong disability live independently. In 2015, 80% of the 110 to 190 million individuals living in developing nations were disabled, including 90 million children. RAF prosthetic leg is product that helps disabled people who lost their leg, to move. This study aimed to create a custom-fit prosthetic leg using 3D printing technology and reduce its weight by utilizing FS3300PA Nylon powder material. T-Scan LV is used to achieve cloud data. Computer Aided Design (CAD) and Finite Element Analysis (FEA) software were used to create and optimize the calf cast geometry. Optimization process able to reduce up to 35% of actual mass of the cast. In addition, 3 force are used which is 480.7N, 730.9N, and 961.38N as the simulated loads to compare between old design and latest design. New design able to deliver good structural result with more additional features like improved air circulation, waterproof and lightweight. Design considers 3.0 < s.f < 6.0 safety factor range, where RAF prosthetic leg able to achieve factor of safety of 5.06. Therefore, it is safe for patient to use. Furthermore, leg fabrication utilized SLS (selective laser sintering) technology which employs a strong laser beam to melt and fuse powdered materials like plastic. Throughout optimization and analysis, the product able to improve from previous version and ensure patient achieve comfort and satisfactory.
