Design and Analysis of Transtibial Prosthesis
This paper presents the analysis of transtibial prosthetics and designing as well manufacturing it through the 3D software Blender and the slicing software Flash print to fabricate a solid physical object i.e. socket for the residual limb under the knee. It has also been thus compared with the traditional way used mostly to prepare the socket manually which was quite labor intensive. This traditional process included a positive mould over which a sheet of thermoplastic after heating is draped around or the positive mould over which materials that are woven together along with the acrylic resins are applied layer by layers. 3D printed technology that has been used took just less than 15 hours as compared to traditional method which takes at least a week or two for the fabrication. 3D printed. The technology that has been used is Fused Deposition Modeling (FDM) and the material used is Polylactic Acid (PLA). This paper also involves studies regarding PLA that has proved eco friendly, inexpensive and dimensionally very stable, also suitable for the skin of human body. Issues related to elevated skin temperature has also been discussed in this paper.
