Soft touch, biocompatible, and tear resistant
SIL 30 is a silicone urethane. It is the first additive material to offer a unique combination of biocompatibility, low durometer, and tear-resistance.
This material opens up the ability to print customized applications for comfortable skin contact products such as headphones, wristbands, and various attachments for wearables.
SIL is a specialty material available for specific production applications.

Example Applications
These applications combine a need for softness, biocompatibility, and tear resistance, in addition to isotropy, great surface finish, and accuracy.
Wrist Bands
Wristbands require a soft touch, biocompatibility, and tear resistance, in addition to isotropy, great surface finish, and the resolution for fine features.
Headphone Pads
Headphones require a soft touch, biocompatibility, and tear resistance, in addition to isotropy, great surface finish, and the resolution for fine features.
