Analyzing the test
Added 2021-03-25 21:07:35 +0000 UTCRunning the first tests with the new WC nozzle I got from Jason and had some interesting results.
I’m using nearly the same gcode here but am finding that the print is more matte using the tungsten carbide nozzle.
On the other hand layer smoothness and extrusion seem better.
After chatting with Jason it’s been confirmed that the outer housing is hardened steel which I concluded to the same after my test prints. Basically the hardened steel being an inferior thermal conductor is acting like an insulator for the tungsten carbide tip of the nozzle. Thermally it’s not very efficient.
Coming from a Nozzle X or a Vanadium I’m needing yet another 5-10C or 15% less fan to get the same print shine.
Could they use a more thermally conductive material? Yes. How about copper? Probably not. Copper is a very dissimilar material and when heated and cooled may cause the tungsten carbide tip to loosen and tighten as the materials expand and contract and vastly different rates. I feel that’s why they used hardened steel along with the fact that copper would also begin to degrade from the use of abrasive materials because the internal throat would still have to take thousands of KM of material running through it. While not as easy to wear as the tip the internal orifice may begin to wear too soon.
I’ve given some feedback and advice to the people who need to know and will go back to testing my theory a bit more and possibly test a few fixes.
