Abstract
Transtibial prosthetic sockets made using selective laser sintering (SLS) of Duraform (™) PA have no documented failure data. In order to produce prostheses with safe weight and usage limits, a non-standard bending test was needed to determine the maximimi safe loading of the socket and to recommend design improvements. The bending test was designed to replicate forces experienced by a wearer stepping down and forward as from a slight elevation. This test, along with a finite element analysis, provided information about the force limitations and weakest point of the socket. Suggestions for improving the design incorporated this information and laid the groundwork for further improvements.
