E-Shell® 200系列

EnvisionTEC’s E-Shell 200 Series is a low viscosity liquid photopolymer that produces strong, tough, water-resistant ABS like parts with high detail that are Class IIa biocompatible according to ISO 10993/Medical Product Law and are CE certified for use as hearing aid products, otoplastics, and medical devices. The E-Shell 200 Series is available in several different skin tone colors and can be customized on demand. Because of their opaque appearance similar to production plastic they can also be used for non-medical applications. The E-Shell 200 Series has been designed especially for applications in the Medical Device and Hearing Aid industries being CE marked as a medical product. E-Shell 200 mimics traditional engineering plastics ABS, which makes it usable in many other non-hearing-aid applications.
