Experimental study of manufacturing of human mandible using fusion deposit modeling (rapid prototyping)

Abstract

Rapid prototyping method is used, for the manufacture of human mandible for replacement for accident victims. Rapid prototyping will make the manufacture of implants much easier and more exact than conventional methods such as titanium implant manufacturing in Alveolar ridge augmentation. After performing the necessary tests, the material selected for usage in the implants was ABS (Acrylonitrile Butadiene Styrene). Tensile tests are performed on ABS for implant manufacturing. Structured Light 3D Scanner is used to scan a life-size human mandible and the Standard Triangular Language (STL) file was created that file has been used in all the processes involved in the modeling and manufacturing of the Human Mandible by Rapid prototyping on ABS. FEM analysis is done on said material at different orientations using ANSYS 2021. From the test results it is found that the ABS material can sustain more than the required average bite force. Furthermore, a comparison of stress and load-bearing ability of bone and ABS is done to confirm the viability as a replacement material for bone in the mandible, which was found to be positive. The biocompatibility of ABS with the bloodstream and the body is researched and found to be positive. Implantation methods and bone powder coating variants are researched, to be able to fit the implant in the temporomandibular joint with the fastest recovery time.
