Ideal nozzle diameter (discuss.tchncs.de)

Hi all

A higher nozzle diameter has the benefit of being able to print faster due to to bigger layer width. There is a tradeoff, you'll have to lower print speed and/or raise temperature to maintain proper layer adhesion. That means that there is an optimal nozzle size for a given print speed/temperature combination. You also don't want temperature too high because it will burn/degrade your filament.

In my experience layer adhesion is quite poor with a nozzle of 0.8mm and it also prevents you from printing finer details (gear teeth for example). The tradeoff versus a 0.4mm nozzle doesn't seem worth it especially if you print overnight.

What are your experiences?

I have a Revo installed on my printer, so changing nozzles is easy. Since the nozzles are standardized and are the same height, I don't need to adjust the Z height.

If layer adhesion is a problem at larger sizes, check the line width, it should be larger than the nozzle size.
