3D-printed hearing aids are bringing a much needed sense of efficiency to the deeply personal devices which require precise customization. Each ear is uniquely shaped, requiring the custom molds of hearing aids to be made by hand -- a strenuous and time-consuming process that lacks automation. Sonova's custom titanium 3D-printed devices are equal parts discreet and functional, serving as the first of its kind on the current market.
Sonova's research suggested that the majority of people requiring hearing aids would rather not wear one at all than wear one that's visible. This information prompted the company to design pieces that could be worn in-ear, instead of wrapped around the lobe. The company is now producing hundreds of custom shells, all of which maintain the same quality and precision as hand molded devices.
