Abstract

This paper explores the feasibility of utilizing 3D-printed materials for lower limb prosthetic sockets, focusing on two specific materials: PA6 and PA6 reinforced with carbon fiber (PA6-CF). Through comprehensive load analysis conducted using ANSYS mechanical simulation software, we examined the structural integrity of these materials under a vertical load of 1300 N. Our findings reveal that while both materials exhibited similar stress levels, however, the PA6-CF material demonstrated significantly superior performance. Specifically, the directional and total deformation of the PA6-CF sockets were reduced to approximately one-third of those observed in the PA6 sockets. Moreover, the inclusion of carbon fiber resulted in a 48.65% increase in the minimum safety factor, highlighting a notable enhancement in strength and durability. These results suggest that PA6-CF offers substantial improvements in stability and safety, making it a highly promising candidate for the development of reliable and robust 3D-printed lower limb prosthetic sockets.
