This paper presents the engineering technique of the rapid hearing aid production with a rapid shell modelling (RSM) Computer Aided Design/Manufacturing (CAD/CAM). It will be worthwhile to describe how the virtual ear shell designed with RSM from an ear impression. And the virtual ear shell model is then used as the template to manufacture the actual ear shell by a Rapid Production (RP) machine. Some detailed description of the whole processing will be given in this thesis. The CAD/CAM method processing will enhance and provide outstanding, high-quality hearing aid shell production capabilities to customers. It reduces the time and the cost of designing products and facilitates direct and indirect manufacturing by creating actual parts directly from digital input. It determines that this technique has made a large impact on hearing aid processing and fitting.
