Different nozzles

Updated 10 days ago ​by Tomáš Chvalina

E3D, a UK-based company, that supplies hotends for the Original Prusa i3 MK2, has a whole ecosystem of upgrades and addons. We support some of them. You have to use proper preset settings for different nozzles in Slic3r or PrusaControl. 

Different settings can be found Settings - Prusacontrol settings - Printer variation - choose nozzle diameter at Prusacontrol. For Slic3r you can find our presets at Plater - Printer. Or you can create your own setting in Printer settings - Extruder 1 - Nozzle diameter.

Hardened steel nozzle

Hardened steel nozzles are a must for highly abrasive materials. Regular brass nozzles will degrade very quickly and lose their properties.

Most of the abrasive materials are composites, plastics with something mixed in. Some examples are ColorFabb XT CF20, ColorFabb Bronzefill, ColorFabb Brassfill and some glow-in-the-dark filaments. Always ask your filament vendor if you are not sure. A slight disadvantage is that some standard materials like ABS aren’t possible to print as fast as with a regular nozzle. 

0.25mm nozzle

To get finer detail on 0.1mm or 0.05mm print settings, you can use a 0.25mm nozzle. But use it for only very small objects, only a few centimeters in size. The print time can be considerably longer compared to 0.4mm. The Ideal use is for jewelry. 

How to tell nozzle diameter right away?

It is rather easy. All of the E3D nozzles got ID dots. With these you can easily determine what kind of diameter it is without any guess work. 

  1. 0.25mm = 0 dots
  2. 0.30mm = 1 dot
  3. 0.35mm = 2 dots
  4. 0.40mm = 3 dots
  5. 0.60mm = 4 dots
  6. 0.80mm = 5 dots
