This is a 0.8mm E3D Volcano replacement nozzle for the E3D V6 Volcano hot end assembly for 3mm filament.

 

The brass nozzle is a great general purpose, low cost option making it a favourite choice in the 3D printing community. Brass has a great balance of properties it is thermally conductive, machines precisely and easily even with very small nozzles and doesn't corrode or pit so retains a smooth surface finish for cleanly laying down extruded filament. The top of the nozzle is threaded in order to fit into the E3D V6 Volcano heater block.

The Volcano Nozzle is 8.5mm longer than standard v6 nozzle, this means that you will need to adjust your Z height in order to accommodate for this and still achieve the perfect first layer. This will avoid an unpleasant crashing of the nozzle into the bed.

The Volcano hot end is designed to melt filament at a much higher rate than the standard E3D-v6 setup. This allows the use of larger diameter nozzles and higher layer heights.

Broadly speaking, printing with Volcano is pretty easy. You just need to ensure that you've setup your slicer to use the correct nozzle diameter, and set a larger layer height.

It is also good to keep in mind that brass nozzles are vulnerable to abrasive erosion by more exotic filaments like carbon-fibre filled materials, metal powder filled materials and glow in the dark filaments and also may be damaged by nasty head crashes.

Changing Nozzles:

When swapping out E3D Nozzles from other E3D components, we recommend resorting to the hot tightening technique. 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 hot end 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 hot side to cool.
  • Re-tighten the heat-break into the heatsink.

The reason for this is that the aluminium heater blocks used by E3D have a higher coefficient of thermal expansion than the brass and steel used in the nozzles and heat breaks. This results in a small gap being created between the nozzle and the break inside the block when the hot end is at temperature, but this only happens if the nozzle has been tightened while cold.

 

*Note this is not supplied by E3D themselves it is manufactured to the same specs and quality controlled locally to ensure it functions exactly as expected while saving you money.
