E3D Volcano nozzles are specifically engineered for the Volcano heater block. Whether choosing standard or extra-large diameters, they enable faster printing with thicker layers and sturdier builds. The 2.85mm Volcano nozzles are also fully compatible with the Lulzbot Moarstruder for enhanced performance. Choose the right material: Nozzle X Nozzle X is the last nozzle your 3D printer will ever need. Made from a hardened tool-steel base, they are then Nickel plated to maintain hardness at elevated temperatures, and have a WS2 coating applied to provide the nozzle with reduced stick properties. Rated to a maximum temperature of 500°C, Nozzle X prints every printable material*, from PLA all the way to Carbon Fibre-filled PEEK without wearing. Brass Brass nozzles, featuring E3D’s signature internal geometry, have optimal thermal properties for everyday printing, providing smooth layers for standard non-abrasive applications. Rated to a max temperature of 300°C. ObXidian ObXidian offers wear resistance far exceeding that of any other E3D nozzle, making it exceptionally durable. It is significantly harder than Nozzle X and all standard hardened steel nozzles. This superior hardness comes from combining a tool steel insert with our advanced E3DLC™ coating. Additionally, this unique coating provides built-in non-stick properties, greatly reducing plastic buildup on the nozzle. Documentation: Please note: Volcano nozzles are not compatible with the V6, SuperVolcano or Cyclops heater blocks. E3D nozzles are identifiable with markings on the flats of the hex head, please see the table below for identification.
