Abstract
A method of manufacturing a hearing device housing including at least one opening. The method includes the steps of: designing a pre-model of the hearing device housing by 3D-modelling software, the pre-model including a protective structure covering the opening, the protective structure being prepared for removal; producing a preform of the hearing device housing based on the pre-model; and removing the protective structure thus providing the hearing device housing with the opening.

A method of manufacturing a hearing device housing (12) comprising at least one opening, said method comprises the steps of:
- designing a pre-model of the hearing device housing (12) by means of a 3D-modelling software, said pre-model comprising a protective structure (102) covering said opening, said protective structure (102) being prepared for removal,
- producing a preform (100) of the hearing device housing (12) based on the pre-model, said hearing device housing (12) is made of a metal comprising titanium, wherein said producing comprises surface treating of the preform (100) by means of vibratory grinding using abrasive media, and
- removing the protective structure (102) thus providing the hearing device housing (12) with the opening.
