Hardened abrasion-resistant nozzles developed to last a lifetime. 3D printing with abrasives such as carbon fiber, glow-in-the-dark PLA or even filled filaments like woodfill all take their toll on a standard nozzle. These nozzles are fully integrated into the E3D Ecosystem and will fit V6, Lite6, and Titan Aero HotEnds, and are compatible with Prusa 3D printers.
