Authentic Micro Swiss nozzles, made in the USA
Every nozzle is a genuine Micro Swiss part — M2 high-speed steel, hardened to 68 HRC and WS2-coated in Micro Swiss’s own US facility. Rev1 Technologies is your authorized Micro Swiss reseller and US support partner, Auburn Hills, Michigan.
Hardened steel that survives abrasives at temperature.
Machined from M2 HSS, hardened and tempered to 68 HRC.
Brass wears open fast with filled filaments, and softens at high temperatures. M2 high-speed steel keeps its hardness up to 450°C and resists abrasion, so the orifice holds its size print after print.
Dry, low-friction, high-temperature surface.
Electroless nickel plating plus a WS2 (tungsten disulfide) coating.
The WS2 coating is a dry, non-stick, low-friction surface that reduces drag and material buildup — cleaner, more consistent extrusion even at high temperatures with engineering polymers.
High-flow geometry — detail to fast draft.
The longer Volcano melt zone feeds big orifices at speed.
Pair the extended Volcano melt zone with a larger orifice (.6–1.0 mm) for high-flow, high-speed functional prints, or drop to .4 mm for finer detail. Same M2 body and WS2 coating in every size.
Built for high-temperature engineering filaments.
Runs up to 450°C without losing its hardness.
From carbon-fiber and metal-filled filaments to high-temperature engineering polymers, the M2 Volcano nozzle holds up where brass and standard steel give out — a nozzle you can standardize a demanding print farm on.
Built for E3D Volcano hotends (1.75mm).
Built for E3D Volcano hotends.
Standard Volcano thread — a true drop-in.
Fits the E3D Volcano and compatible high-flow hotends for 1.75 mm filament — a true drop-in with the standard Volcano thread. Not sure? Call us with your printer model and we’ll confirm before you buy.

FAQ
M2 Hardened Steel Volcano Nozzle (1.75mm) — Questions
Does it fit my Volcano hotend?
It fits the E3D Volcano and compatible high-flow hotends for 1.75 mm filament. Not sure? Call us with your printer model and we’ll confirm before you buy.
Why M2 steel over brass?
M2 high-speed steel holds its hardness at high temperatures (up to 450°C) and resists abrasion far better than brass — so it keeps its orifice size when printing carbon-fiber, metal-filled and high-temp engineering filaments.
What does the WS2 coating do?
The WS2 (tungsten disulfide) coating is a dry, non-stick, low-friction surface that reduces material buildup and drag for cleaner, more consistent extrusion at high temperatures.
