Design and realization of hearing aids based 3D rapid shell mold ing CADCAM

This paper reports on the technique of rapid production of hearing aids with rapid shell modelling (RSM) Computer Aided Design and Manufacturing (CADCAM). It will be worthwhile to understand how the virtual shell designed with RSM from the ear impression. And this virtual shell model is then used as the template to manufacture the actual shell by the RP machine. A detailed description of the processing will be given in this paper. There is also a comparison of conventional manufacturing and this new method processing. We determine that this technique has made a large impact on hearing aid processing and fitting. This new method processing will enhance and provide outstanding, high-quality hearing aid shell production capabilities to customers. Its systems reduce the time and cost of designing products and facilitate direct and indirect manufacturing by creating actual parts directly from digital input.
