The goal of this senior project was to design and fabricate a low-cost adjustable prosthetic socket for above the knee amputees. This low-cost consideration was incorporated with the original intent to be used in Fiji, however, this changed to the Dominican Republic. It became clear that the need for an adjustable socket was more as a transitional socket. This transitional socket would be used for the first 6 -12 months upon amputation because this when the most amount of volume fluctuation occurs. The project sponsor, LIM Innovations, has already designed the Infinite Socket which contains four main functioning parts: baseplate, …

Mechanical Engineering
The metallic additive manufacturing process known as selective laser melting requires highly spherical, normally distributed powder with diameters in the range of 10 to 50 microns. Previous observations have shown a degradation in powder quality over time, resulting in unwanted characteristics in the final printed parts. 21-6-9 stainless steel powder was used to fabricate test parts, with leftover powder recycled back into the machine. Powder samples and test specimens were characterized to observe changes across build cycles. Few changes were observed in the physical and mechanical properties of the specimens, however, there were indications of chemical changes across cycles. Potential …
