Onyx® — our flagship Composite Base material — is a micro carbon fiber filled nylon that yields accurate parts with near flawless surface finish. Few materials have the versatility of Onyx; it offers high strength, toughness, and chemical resistance when printed alone, and can be reinforced with Continuous Fibers to yield aluminum-strength parts. Today, there are more than a million Onyx parts in the field transforming manufacturing.
