This Genuine E3D Volcano nozzle in copper is offered in 1.75mm and 2.85mm filament sizes and a wide range of orifice sizes. Copper nozzles offer smooth and consistent flow and are capable of printing at much higher temperatures than brass.
These nozzles are engineered for ultimate high-temperature performance. Made from a special high-temperature copper-alloy with a softening point of well above 500C, and much-increased thermal conductivity these copper nozzles are perfect for high-temperature applications while working perfectly with everyday filaments like PLA, ABS, and spoolWorks EDGE.
In addition to high-temperature performance these blocks have advanced nickel-based plating, this plating considerably reduces the adhesion of plastic to the nozzle. This is great for everyday filaments keeping things clean and shiny but is particularly important at temperatures above 300C where a silicone sock can't be used.
Combine with our plated copper blocks for the ultimate extrusion pairing.
Copper has more than 3x the thermal conductivity of brass, and the copper alloy we use has been hardened and treated to reduce the oxidation that occurs in copper at high temperatures. The higher specific heat (thermal mass) will very slightly increase your heat-up times and can provide tighter temperature control.
This copper-alloy is very temperature resilient, and will not start to soften or anneal until way beyond 500°C, making it perfect for the high-temperature printing that other nozzles can't handle.
All nozzles in the series are now individually identifiable with markings on the flats of the hex head making them even more convenient to work with. See the table below for more information on what these markings mean:
