Design and Development of a 3D Scanner Using Photogrammetry for the Generative Design of Low-Cost Hand Prosthesis Using Rapid Prototyping Technologies

Abstract

This study focuses on design and development of a 3d scanner using photogrammetry as the principal technique to build hand prostheses. This work also applies generative design principles, manufacturing knowledge and industrial design concepts to optimize the development of the final product in comparison with existing typologies on the market. The construction of this 3d scanner prototype responds to the necessity of facilitate the creation process of hand prostheses. This device takes advantage of the use of cameras to capture information about the hand features. After that, the 3d scanner digitalizes the information, avoiding wasted time on digital modeling or traditional methods to elaborate hand prostheses. This 3d scanner prototype aims to optimize time, development processes and the cost of hand prostheses through the use of rapid prototyping (RP).
