Abstract :
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.
