The global market demand for prosthetic limbs is increasing, as it depends on a variety of factors such as the prevalence of limb loss and the availability and affordability of prosthetic technology in different regions of the world. . However, the fabrication of the lower limb prosthetic takes about 4-6 weeks and the prosthetic weighs between 2000g and 4000g. In this context, a lot of research was done on creating low weight lower limb prosthetics using a variety of techniques. However, there hasn't been much work done to create lightweight lower limb prosthetics utilizing 3D printing techniques. In this paper, different models made with lightweight construction and ASTM-tested PLA material were analyzed in order to demonstrate and offer a feasible option for lower limb prosthetics. The compression test analysis was performed on the developed 3D models under static structural conditions, The three models created based on different structure was tested under the boundary condition with a loading force of 1.5kN and the model 1 exhibited stress of 40.133 Mpa, the model 2 exhibited stress of 6.37 Mpa, the model 3 exhibited a stress of 6.58 Mpa for the applied load. The model which exhibited a stress of 6.37 Mpa for the applied load of 1.5 kN was selected and 3D printed. The 3D printed lower limb prosthetic weighs 400 grams which accounts to 80% weight reduction as the conventional lower limb prosthetic weighs 2000 grams and the time taken to fabricate is two days compared to the conventional method which takes about 4-6 weeks. The cost of fabricating the lower limb prosthetic was 4800 INR. The 3D printed lower limb prosthetic can be customized as per the client’s requirement.
