Is the silicon carbide from Phaetus a good and inexpensive alternative to the E3D Nextruder nozzles?

We compared three different nozzles to determine the maximum flow rate in mm3/s. We didn’t expect the values ​​to be so close. Of course, even more can be achieved by increasing the temperature.

A comparison with the Nextruder CHT nozzles would also be interesting. However, CHT nozzles also have a disadvantage: They clog more easily and are harder to clean.

There is now also a Diamondback Nextruder nozzle from E3D. However, at over €100, this is quite expensive.

We probably won’t be able to tell how the SiC nozzle performs in the long-term damage test for another year or two. However, I already have a Pheatus tungsten carbide nozzle on my Prusa MK3, which I’ve used a lot over the past two years, and it’s still performing well today. And with this nozzle, I can print at 10 degrees cooler than with the Nozzle X from E3D.

The Phaetus SiC Nextruder nozzle costs only around €22. This makes it not only better in terms of thermal conductivity and wear resistance, but also significantly cheaper than the E3D Obxidian nozzle. You can buy the nozzle here (affiliate link): https://s.click.aliexpress.com/e/_DDh6ZFJ

The filament I used is from Sunlu and is called PLA Meta. It’s suitable for high-speed printing. It typically prints at 185-190°C. Regular PLA would require a higher temperature to achieve the same flow rate.
