Nozzles

Which nozzle to choose?

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.

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.

Hardened steel is somewhat less thermally conductive than brass, however in our testing this does not seem to have a noticeable impact on actual performance and print speed. Probably because the limiting factor is the conductivity of the filament, not the nozzle. Hardened nozzles are brittle, it's extremely hard to break one but if you do manage they crack rather than deforming. Hardened steel nozzles are so hard that they can score and damage even glass print surfaces if dragged across the surface with force.

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.

Unless you have a specific need for stainless steel nozzles you're probably better off going for brass or hardened steel. Stainless is much less conductive than brass, less wear resistant than hardened steel.

Identification

# of Marks Nozzle Size
0 0.25mm
1 0.30mm
2 0.35mm
3 0.40mm
6 (Sorry..) 0.50mm
4 0.60mm
5 0.80mm

Swapping

To swap out a nozzle, you must follow this procedure - being careful not to burn yourself.

  • Unscrew the heat-break from the HeatSink half a turn to be sure you are not tightening against the heat-break in later stages.
  • Heat up your HotEnd to 285*C. Do not overshoot as you risk damaging your thermistor.
  • Remove the existing nozzle from the heater block.
  • Insert the new nozzle.
  • Gripping the heater block tighten the nozzle. Do not apply any torque through the heat-break, they are fragile.
  • Turn off the heat and allow the HotSide to cool.
  • Re-tighten the heat-break into the HeatSink.

v6 Fan Duct

Our fan duct has been carefully designed to direct flow over the fins of the v6 heatsink so that it gets the cooling it needs. The design is for injection moulding but will work just fine when printed. The STL and STEP files are available on thingiverse.
