Prosthetic Leg - Fatima

prusaprinters

<p>This is a fully 3D printable prosthetic leg we have provided for Fatima, a two year old double amputee. The design was made in Autodesk Fusion 360 and was printed in three iterations before we have achieved the right fit and function. The parts under mechanical stress are printed using Prusament PC blend while the socket is made from PLA to allow thermoforming in order to achieve the tight fit. The thermoforming was done using the hot water and plaster mold of the Fatima's legs.</p><p><strong>Fatima's Story:</strong></p><p>Fatima is a two year old child who lost both her legs due to certain medical issues. &nbsp;A Gambian charity “<a href="https://m.facebook.com/story.php?story_fbid=4401540763201670&amp;id=135225263166596">The Glove Project</a>” came to us to if we can provide prosthetic leg for her. The locally made solutions were too heavy and high, so she was not able to walk correctly and get up without help when she fell down. Within two weeks we have been able to design, prototype, fit and finalize the product. Fatima and her mother choose the pink color for the sockets and during our last session Fatima was playing with a ball and running around the office on her new legs. &nbsp;Fatima and her mother were so very happy with these prosthetics that I remembered seeing her cry when they are taken off her legs.&nbsp;</p><p><strong>Print instructions:</strong></p><p>All printed with Original Prusa i3 MK3S, with 0.4mm</p><p>Socket:PLA, Infill 100%, 3 perimeters, layer height 0.3mm, supports on build plate only</p><p>Rubber cube: Filatech Filaflex 40, Infill 60%, 2 perimeters, layer height 0.3mm</p><p>Foot grip: Filamentum Flexfill 98A, Infill 100%, 2 perimeters, layer height 0.3mm</p><p>Joint: Prusament PC blend, 100% infill, 3 perimeters, layer height 0.2mm, print on the side with the hole for the nut up</p><p>Foot: Prusament PC blend, 20% infill, 3 perimeters, 10 bottom solid layers</p><p>&nbsp;</p><p><strong>Additional material:</strong></p><p>1 bolt and nut for the socket, 1 bolt and nut for the joint, spring</p><p>&nbsp;</p><p><strong>Assembling:&nbsp;</strong></p><ol><li>Glue the foot grip to the bottom of foot, and wait for it to dry (we have used regular super glue).</li><li>Glue the rubber cube in the foot.</li><li>Insert the spring between the foot and joint</li><li>Insert the joint on the foot and tighten a bolt and nut slightly.
