This bachelor's thesis was a collaboration with Lindhe Xtend AB and covered up to find asubstitute material for the prosthetic socket. It was a concept of design on how to evenlydistribute force/pressure around the residual limb on the socket. The project employed amethodical material selection process using Granta EduPack, which involved translatingrequirements, screening, ranking materials, and deepening the investigation through simulationand physical testing. Polylactic Acid (PLA) infused with 30% mineral content emerged as themost suitable material due to its mechanical properties, cost-efficiency, and lowerenvironmental impact. Finite Element Analysis (FEA) and compression tests confirmed thematerial's strength, durability, and comfort under various loads. The results demonstrated thatthe PLA-based material is suitable for practical prosthetic applications. Additionally, the projecthighlighted the benefits of 3D printing technology in improving the accessibility andsustainability of prosthetic devices.
