Abstract

3D printing manufacturing process has the possibilities to produce individual medical devices, especially implants and prosthesis with short production time. The aim of this study is to design a 3D printable Energy Storage and Return (ESAR) foot prosthesis for transtibial amputees with a novel geometry. The criteria of the prosthesis were 3D printable, low cost, simply geometry and satisfying mechanical properties for low activity use. The finite element analysis of the designed foot prosthesis was conducted in each of the three support phases of the walking cycle (controlled plantarflexion, controlled dorsiflexion, powered plantarflexion or push-off phase). Besides of the simulations the prototype was printed by fused deposit modeling (FDM) technology, used ABS material and the produced prototype was investigated in quasi-static and cyclic compression. It can be stated after the investigation (simulation and test) that the 3D printed prototype fulfill the requirements and it can be used as passive ESAR foot prosthesis.
