Abstract
This paper aims to provide a low cost solution for the manufacture of lower limb prosthesis adapter, due to the high market value. Simulations were performed in the Inventor software and compression tests on samples made in 3D printer whose configurations are in agreement with the orthogonal distribution of Taguchi. We applied loads of 300N, 1000N and 3000N in both the simulation and the compression tests. The highest deformations were of 0.07898mm and 0.449587mm for simulations and compression tests, respectively. The simulated safety factor was 15 and the minimum load leading to the formation of cracks and settling was 13505.3N. These values satisfy a maximum deformation limit of 3mm for the mentioned loads, indicating that 3D printing is a reliable way of manufacture such components.
