This study aims to employ the technology of rapid prototyping for the development of a process that is to assist a prosthetist for easily designing and manufacturing a prosthetic socket for specific transtibial amputee. Currently, the production of prosthetic socket still depends on prosthetists' skills and expertise. To improve its tedious process, quality uncertainty, and lack of experienced prosthetists. the benefits of using rapid prototyping (RP) technology together with computer-aided systems will be expecting goals. This article demonstrated the feasibility of producing RP sockets using a fused deposition modeling (FDM) machine, and a prototype system that allows a prosthetist to easily design prosthetic sockets has been developed. This proposed computer-aided engineering process, which is plaster-free method, is expected to replace the manual process of conventional approach of fabricating prosthetic sockets. Furthermore, since thin-layer RP socket is easily broken, coating a resin layer on RP socket to enforce its strength is underway.

In the process of reducing the production cost and satisfying the customer and to sustain in the current volatile market, the manufacturing companies are looking for alternate processes and methods of designing and manufacturing. The conventional CAD/CAM tools are developed to meet the general needs of the market, but not the rapid or specific requirements of the market or customer. Consequently, the companies are looking to customize or tailor the CAD/CAM tools to improve their effectiveness. For this reason, the scope of research in the field of customization of designing tools has improved rapidly in the recent time. This paper discusses an introductory approach for developing an knowledge based system for CAD modelling using customization process of an CAD/CAM tool. The intension behind the development of the system is to reduce the production time and cost. The effectiveness of the proposed system has been examined using an industrial case study.
