This 0.4mm MK10 Nozzle is designed for 3mm Filament 3D Printers and is stocked as a replacement part for the Wanhao Duplicator 5. It is made from durable and thermally conductive brass, and is a great choice for 3D printing in ABS or PLA Filaments, as brass is more than capable of handling the abrasion of these softer plastics, with a long lifespan of good quality extrusion.

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 a high level of 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.

Quick Guide to Changing your Wanhao D5 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 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 do 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.

0.4mm Mk10 Nozzle for D5/D5S

Wanhao have been supplying 3D Printers internationally since as early as 2012, and have rapidly garnered a world-renowned reputation for quality machines, parts and components. After originally banding together as a group of friends and purchasing a Makerbot Thing-O-Matic, they created their own “Duplicator 1” 3D Printer, which was essentially a replica of the Thing-O-Matic, with slight modifications and alterations to make it better suit typical users.

Wanhao’s strengths have always stemmed from the fact that they are both 3D Makers and 3D Printer Manufacturers, which allows them to understand the needs of the end user when developing new models or upgrades. It is the same reason why they always make sure to stock spares of all of the different parts and components, because they believe that you should never have to buy an entirely new printer if one part breaks, and should instead be able to simply replace whichever part is broken.

There are few 3D Printing manufacturers with as much experience and reputation as Wanhao, which is why we have chosen them as one of our top suppliers here at DIYElectronics. Not only do they continue to bring out exciting new models and upgrades for existing models, but they also align with our own company culture and values by proactively supplying all of the spare parts that customers might need – so that you, as an end user, never have to source spares or alternatives if you have problems with faulty or broken parts throughout the lifespan of your 3D Printer.
