Abstract

The paper idea was to investigate is it possible to design running prosthesis with similar design as running blades using only 3D printing technique and ABS, as one of the most used plastic material in the world. This material is very strong and manufactured parts are not very flexible. By using metamaterials some models of human running prosthesis were created and a number of simulations were made through SolidWorks Design Study package. Used approach allows finding of the best solution for custom-made human running prosthesis with the best characteristics. Present paper gives the evidence that using of smart geometrical design of inner structure of various parts and models to reduce its mass and improve their mechanical characteristics is possible. Also, obtained model is suitable for 3D printing and it can be opportunity to product cheap prosthesis for a large number of people with disability.
