HERSTELLUNGSVERFAHREN UND SYSTEM ZUR SCHNELLEN ERZEUGUNG VON HÖRHILFEGERÄTSCHALE

摘要

The method for manufacturing an in-the-ear shell for a hearing device comprises the steps of automatically generating a first three-dimensional digital model of the surface that describes the shape of an ear canal of a subject as a 2-manifold surface which has zero or nonzero functional boundary, from captured three-dimensional data. There is generated a second three-dimensional digital model of a thickened in-the-ear shell from the addressed first three-dimensional digital model. There is then printed the second three-dimensional digital model as an in-the-ear shell. Quality assurance is performed by comparing at least two of the first three-dimensional digital model, the second three-dimensional digital model and the third three-dimensional digital model which is derived from the printed in-the-ear shell.
