Nozzle X

Designed to be the one nozzle for all your printing needs, Nozzle X combines the abrasion resistance of the hardened steel nozzles, the heat resistance of the plated copper nozzles and has a poly-phobic coating to prevent clogs on the inside of the nozzle and prevent filament sticking to the outside of the nozzle. The ideal nozzle for filaments such as carbon fibre filled PEEK. Unlike other insert based high temperature abrasive resistant competitive nozzles Nozzle X benefits from the same proven internal geometry as all of our other nozzles to avoid overly high back pressure issues.

68 HRC Tool steel: Harder than our current hardened steel range. Super abrasion resistant.
73 HRC Electroless Nickel Plating: Plated coating that makes it resistant to heat, operating at temperatures 500°C +
Poly-phobic coating WS2 coating: The coating is slick and helps internal flow rates.

Operates the same way an umbrella brushes water off it but with polymers to create something which naturally repels polymers and prevents clogging better than ever before.

Brass

General purpose, low cost, great for printing materials that don't have anything abrasive in them. Brass has a great balance of properties; thermally conductive, machines precisely and easily even with very small nozzles, doesn't corrode or pit so retains a smooth surface finish for cleanly laying down extruded filament.
Vulnerable to abrasive erosion by more exotic filaments like carbon-fibre filled materials, metal powder filled materials and glow in the dark. Can be damaged by nasty head crashes with things like bulldog clips and glass. Using a wire brush on a brass nozzle will cause wear over time.

Plated Copper

These are the latest addition to the E3D ecosystem and provide an increased thermal conductivity. The nickel coating here has low surface energy which reduces plastic adhesion, and has potential to increase flow rate. Copper alloy also performs better at higher temperatures than other nozzles. Great for sticky materials like TPUs and PET-Gs as well as extreme temperature polymers like Ultem.

Hardened Steel

Designed to resist the abrasion of materials filled with abrasive particles which act like liquid sandpaper on your nozzle. Carbon-fibre is a particularly abrasive and well known example for which these nozzles are ideal. Materials filled with metal powders can also be abrasive, as can glow in the dark pigments. Hardened steel nozzles are nearly impervious to wear and should last as long as your printer. Hardened steel nozzles are also very resilient to being damaged by things like crashing into glass, bulldog clips or getting mangled when you're too lazy to find the correct size 7mm spanner and use pliers instead, we know you do it. You can use a wire brush to clean a hardened nozzle without damaging it. See this blog post by E3D for more information on Hardened Steel Nozzles:

Stainless Steel

These are for specific applications by popular request of certain customers, usually where there is a food or medical need and the other two alloys are not acceptable for regulatory reasons. We don't certify or make promises that these nozzles are suitable for these applications, as this is down to each users individual machine and process. Stainless is somewhat more abrasion and abuse resistant than brass, but not better than hardened. Stainless steel can be useful for some very odd chemically corrosive materials.

Experimental

Here be dragons! These nozzles conform to our strict manufacturing and engineering guidelines, but might still need more know-how and practice than others in our range.
This collection includes high-resolution 0.15mm nozzles for very very tiny printing. We also offer undrilled nozzles for those who like to make their own.
