Our printers come equipped with a standard E3D 0.4mm nozzle. However, there is a whole ecosystem of various nozzles with different characteristics on the market. If you decide to get a new nozzle, please refer to our guide Changing or replacing the nozzle. Also, don't forget to adjust the preset settings in Slic3r PE or PrusaControl, if you change the type of the nozzle.
To adjust preset settings in PrusaControl or Slic3r PE:
- PrusaControl: Settings - Prusacontrol settings - Printer variation - choose nozzle diameter.
- Slic3r PE: Plater - Printer - choose nozzle diameter.
Hardened steel nozzle by E3D
E3D, a UK-based company, that supplies hotends for the Original Prusa i3 printers, has a whole ecosystem of upgrades and add-ons. We support some of them, including the 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 additives. 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 about filament requirements. A slight disadvantage of the hardened steel nozzle is that some standard materials like ABS cannot be printed as fast as with a regular nozzle.
The Olsson Ruby nozzle
Similarly to hardened steel nozzle, the Olsson Ruby is designed to print highly abrasive materials. Since it is mostly made of brass, it retains the excellent heat conductivity and throughput of the stock brass nozzle. Even though the ruby gemstone is highly wear-resistant, it’s also brittle. If you have the Live Z adjust value set incorrectly, or if you misalign your P.I.N.D.A. probe and the nozzle hits the removable steel sheet, the nozzle may crack. Also, do not overtighten it during assembly (1 Nm max).
0.25 nozzle by E3D
E3D, a UK-based company, that supplies hotends for the Original Prusa i3 printers, has a whole ecosystem of upgrades and add-ons. We support some of them including the 0.25 nozzle.
To achieve 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, e.g., a few centimeters in size. Print times can be considerably longer compared to 0.4mm nozzles. The ideal use is for jewelry.
