This 0.4mm MK8 Large Nozzle is designed for 1.75mm Filament is stocked as a replacement part or upgrade for MK8-compatible Hotend Assemblies. It is made from durable and thermally conductive brass, and is a great choice for 3D printing in ABS or PLA Filaments at relatively high resolutions.

Whether you are looking for a replacement nozzle for your 3D printer, or are eager to upgrade to a larger or smaller nozzle depending on your 3D Printing needs, this 0.4mm nozzle strikes the perfect balance between printing speed and accuracy.

As a final note, don’t forget to utilise the hot-tightening technique explained below, to ensure that it works optimally in your 3D printer without causing any unnecessary problems.

Changing Nozzles – The Hot Tightening Technique:

When swapping out 3D Printer Nozzles on a 3D printer, 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 often 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.
