The EnvisionTEC E-Silicone

The EnvisionTEC E-Silicone resin is designed as a solution to produce soft silicone otoplastics through the 3D printing of cocoon molds. After the mold has dried it can then be injected with medical grade silicone materials. The eggshell-like mold may then be easily broken away, leaving a soft, flexible shell. When using this method for the preparation of hearing aids, these shells can provide increased wearing-comfort, better retention, better acoustic sealing and more gain before feedback and improved sound quality.
