The E3D Brass Volcano Nozzle 1.75mm-0.4mm is a high-flow nozzle for Volcano HotEnds. It is designed to print at large layer heights and extremely high flow rates.

Yes. This brass nozzle is made for use with the Volcano block and Volcano packs in an E3D Volcano HotEnd setup.

Yes. The nozzle is immediately compatible with the Lulzbot Moarstruder.

Yes. Many RepRap 3D printers can be upgraded with an E3D Volcano, which allows use of this nozzle.

This version is for 1.75mm filament.

Yes. E3D describes the 0.4mm to 0.6mm range as the industry standard, offering a practical balance between resolution and print speed.

For a V6 setup, E3D notes that a 0.4mm nozzle works best with 0.25mm layer heights. Volcano systems are also used for larger layer heights depending on the nozzle size.

Volcano nozzles have an extra-long heated melt zone that increases filament melt speed. E3D also optimized the internal geometry for higher flow and throughput.

A wider nozzle produces a wider printed track, which can improve part strength. It also supports thicker layers, which can reduce total print time.

E3D nozzles are identified by the number of dots drilled into the nozzle hex flats, as referenced by E3D's sizing table.
