This 0.3mm Stainless Steel Nozzle is designed for 3mm filament with high abrasion, and is made to last the heavy wear and tear that some Exotic Filaments like glow in the dark or metal-imbued filaments often cause. This is thanks to the harder, more durable materials of these nozzles, which are less malleable than brass but substantially more resistant to corrosion and pitting.

While these nozzles are made specifically for highly abrasive filaments, they are slightly more expensive than brass variations, which is why many of our customers purchase these stainless steel nozzles for specific applications that require high resistance and durability. Conversely, brass nozzles are most often used for general 3D Printing applications that don’t require high corrosive, thermal or abrasion resistance.

As a final note, because stainless steel Nozzles don’t conduct heat as efficiently as the brass variations in the E3D Range, you might have to set your nozzle temperature about 2°C to 4°C higher than usual.

Simple Guide to Changing your 0.3mm E3D Stainless Steel Nozzle:

When swapping out 3D Printer Nozzles from other components, we recommend utilising the hot tightening technique for optimal thermal coupling. To do this, simply follow these easy steps, while being careful not to burn yourself of course.

  • Unscrew the heatbreak from the heatsink by about half a turn, to be sure you are not tightening against the heatbreak in later stages.
  • Heat up your hotend to 285°C, but do not overshoot as you risk damaging your thermistor.
  • Remove the existing nozzle from the heater block and insert the new nozzle.
  • While firmly gripping the heater block, slowly tighten the nozzle. Be careful, however, that you not apply any torque through the heatbreak, as they are fragile and relatively easy to break when loose.
  • Turn off the heating unit and allow the hot side to cool.
  • Finally, once the nozzle is installed and cooled down, tighten the heatbreak back into the heatsink and ensure that there are no loose parts.

The reason for this is that the aluminium heater blocks used 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.
