The Top Choice for 3D Printed Hearing Aids, Inner-Ear Devices —

From the beginning, EnvisionTEC has been the 3D printer of choice for audiologists, hearing aid manufacturers such as Phonak and GN Resound, and pretty much anyone making inner-ear devices.

Extreme accuracy isn’t the only reason we’re No. 1. The ability to deliver smooth, organic shapes that fit snugly in the ear, as well as good color choices, help.

But the real reason is simple: We listen. We’ve worked hand-in-hand with the audiology market since it began using 3D printing technology to improve the printers and materials specifically for the market, so we can deliver durable, reliable shells with thin walls to accommodate electronics.

And our E-Shell 451 Carbon Black (shown in the 1964 Ears photo at left) is a fashion-forward shade that kicks style up a notch.

e-shell-450-300x229In all, we offer more than 16 biomedically approved materials with various skin-tone colors, along with red, blue, pink, tan, mocca, beige, cocoa, brown, black, white, rose clear and crystal clear.

For applications ranging from individual ear molds to shells with integrated face plates the Perfactory® DLP® process can supply high quality parts in bespoke materials.

The economics of running a Perfactory DSP makes it the preferred choice for the hearing aid industry, with our technologies providing up to 65 ear shells or 47 ear molds in 60 minutes.
