Is the silicon carbide from Phaetus a good and inexpensive alternative to the E3D Nextruder nozzles?
We compared 3 different nozzles to determine the maximum flow rate in mm3/s. We did not expect the values to be so close to each other. Of course, even more can be achieved by increasing the temperature.
A comparison with the Nextruder CHT nozzles would also be interesting. However, the CHT nozzles also have a disadvantage. They clog more easily and are more difficult to clean.
We will probably only be able to say in one or two years how the SiC nozzle performs in the long-term damage test. However, I already have a Pheatus nozzle made of tungsten carbide on my Prusa MK3, which I have used a lot over the last two years, and it is still good today. And with this nozzle I can print at 10 degrees less temperature 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 use is from Sunlu and is called PLA Meta. It is suitable for high-speed printing. It is normally printed at 185-190°C. With normal PLA, you would need a higher temperature to achieve the same flow rate.
