In early 2019, Otic introduced the latest 3D scanning, modeling and 3D printing technology. The earmould and shell production has been changed from the hand-made production to the state-of-the-art computer-assisted production.
The earmould technician will first scan the ear impression into a 3D image. Traditionally, the ear impression can only be stored for three months without any distortion. Now, the scanned 3D image can be stored permanently, and it is much more convenient for re-production of earmoulds and comparisons of ear impressions in the future.
After the 3D Image is modeled, the earmould/custom-made shell can be accurately printed with a 3D printer. The output will then be ready for post-process/custom-made hearing aid assembly.
The earmould technician utilizes the computer and 3D mouse to design appropriate style and shape from the 3D image; the modelled 3D image data can be stored permanently for future reproduction.
