Description

Rapid Orthotics for Cure Kenya (ROCK) collaborates with CURE, a non-profit orthopedic workshop in Kjabe, Kenya, to implement a 3D printing system for manufacturing custom prosthetics and orthotics. The goal is to reduce the production time and cost for the current transtibial sockets being manufactured in the orthotic workshop to give the patients a way to integrate into society and reduce stigma from their communities. The team designed a system for manufacturing transtibial sockets by converting a scan of the residual limb to a digital file customized by the orthopedic technicians and converted to a file to be 3D printed. The team designed a procedure to ensure the safety of the sockets within the constraints and offsets of the ISO 10328 Standard. The standard requires twelve official tests specifying the type and conditions to be conducted for the Ultimate Strength and Static Proof tests. The team has designed a testing rig that interfaces with the Materials Testing System machine at Messiah University to apply the necessary forces according to the complex geometry outlined in the standard. Additionally, research has determined the optimized 3D printing settings to increase the quality and consistency of the sockets. To smoothly institute the system developed in the orthopedic workshop, the team has developed a Training Manual outlining the step-by-step procedure for the system. Using this system, the team completed all twelve tests with a passing socket result which will contribute to determining the steps for next semester and for the summer site team trip.
