Material selection for biomedical application in additive manufacturing using TOPSIS approach

Abstract

In ortho-prosthetic industries, the latest development of rapid prototyping is introduced, specifically process of manufacturing orthopedic assistive devices is analysed its use has been widely expanded in orthopaedic operation. These tools are used for correct posture or movement (orthotics) or to auxiliary part of respective shape (prosthetics) while maintaining function. The production of customized base or ankle prostheses still depend on the unhurried and laborious stages of outdated plaster model making technology. Additive manufacturing technology in which three-dimensional substances can be directly created based on data computer-aided-design of layered objects to manufacture new and modified medical equipment. The motive of this paper is to search out the materials for biomedical application and then prioritize the suitable materials by TOPSIS (technique for order performance by similarity to ideal solution) approach. This approach will provide the rank of the suitable materials, which fit for biomedical products or device. Clinical trials were conducted on the prosthesis, or it was successful in terms of wearing practice, looks (colour), and adoption of materials and technology.
