DUROZZLE takes genuine ruby as the tip material for all its ruby series nozzles. It offers excellent durability and resistance to highly-abrasive filaments like carbon fiber, glass-infused materials, or metal-filled filaments. It can also print standard materials such as PLA, ABS, PETG, TPU etc.

• Compatibility: Compatible with Ender 3 Series / Ender 5 Series / CR-10 Series, Elegoo Neptune 3 / 3 Pro / 3 Plus / 3 MAX, Sovol SV01 / SV03 / SV04 / SV05 / SV06 and other 3D Printer models and hotends that use MK8 nozzle;
• Not compatible with Ender-3 V3/Ender-3 V3 Plus/Ender 5 Max 3D Printer;
• Enhanced Thermal Conductivity & Durability: Made from a high-performance copper alloy, this nozzle significantly improves heat conductivity, enabling faster and more efficient 3D printing. The nickel coating offers multiple benefits—including non-stick to material debris, a hardened surface for extended wear resistance, and protection against copper oxidation—ensuring superior performance even under demanding printing conditions;
• Genuine Ruby: DUROZZLE takes genuine ruby as the tip material for all its ruby series nozzles. It offers excellent durability and resistance to highly-abrasive filaments like carbon fiber, glass-infused materials, or metal-filled filaments;
• Funnel Shaped Nozzle: DUROZZLE's ruby nozzle is carefully cut and polished to have funnel shape structure. This will avoid accumulating material at the dead corners in this way to reduce risk of carbonization and nozzle blockage;
• One For Any Material: Having great performance in printing highly abrasive materials, less abrasive materials such as PLA, ABS or Nylon are never challenges for it. Ruby nozzle can improve the nozzle service period in an obvious way, keeping you free from replacing nozzles frequently.
