2mm Large Nozzle for 3mm Filament

These 2mm Large Diameter Nozzles for 3mm Filament are some of the largest 3D Printer Nozzles that we stock, alongside our 1mm and 2mm nozzles. They are built for high speed 3D printing, at the cost of precision, and are perfect for prints that you need to produce rapidly without requiring a high level of detail – such as doorknobs, enclosures and similar objects.

Despite the much larger size than many of our standard nozzles, these nozzles are still fully compatible with most 3mm filament Hotend Assemblies like the E3D V5 and E3D V6. This gives you more options when 3D Printing, as you can choose to print highly-detailed objects with smaller nozzles, and then switch to these big boys when your top priority is printing speed rather than accuracy.

Quick Guide to Changing your 2mm Large Diameter Nozzle:

When swapping out 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 heat break from the heatsink by about half a turn, to be sure you are not tightening against the heat break 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 heat break, 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 heat break 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.
