Objective To develop a more efficient and secure method of making three-dimensional ear mold. Methods For a behind the ear (BTE) hearing aid, an ear mold that fits the individual’s ear canal is needed. We establish the solid mold by using the MIMICS and Solidworks to process the images from the CT scanning of the volunteer’s ear. Results Compared with the traditional method, the ear mold made by computer aided design (CAD) technology fits better to the individual’s ear. Conclusions CAD makes ear mold fabrication more safe, convenient and efficient.
