Mechanical performance analysis of a 3D printing-based transtibial prosthetic socket against the gait cycle using the finite element method.

In order to restore near-normal gait patterns and increase patients' mobility post-amputation, prosthetic sockets are crucial. Currently, few 3D-printed prosthetic sockets are available, and little research has been conducted on their mechanical performance. Thus, the purpose of this study is to assess and characterize the performance of polyethylene terephthalate (PET), polycarbonate (PC), and polyamide 6/Nylon 6 (PA6) materials in prosthetic sockets fabricated 3D printing.
