I recently started using some ebay-sourced stainless steel nozzles because of some filled filaments I plan on printing with, but I know that stainless has less thermal conductivity. I printed a temperature calibration piece, and it failed pretty bad, but it looked like a partial clog that cleared itself later in the print is what caused the issue, but I'm not sure if that's actually what happened. With what I could salvage, the layer adhesion at 210C was about the same as the layer adhesion of a brass nozzle at 175C. That seems like a pretty extreme temperature difference, but the poor performance of the stainless nozzle could have been due to whatever happened that caused the print to fail (it was overnight, I didn't watch it).
Basically, how much does a stainless nozzle actually affect print temperatures?
