A 3d digitizer for hearing aid moulds


Hearing aid devices can be customized to the inner ear channel shape of each person. P3 is a prototype for 3d digitization of hearing aid moulds. They are necessary to build custom intrachannel hearing aid devices. They are made to fit into the ear, and thus must conform to the particular anatomy of each customer. The three-dimensional digitization would allow to address the automatic fabrication of ear shells by means of 3d printers.
