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?

What is your use case for stainless nozzles? For abrasives I use Hardened steel nozzles just to not lose even more thermal conductivity.

Food grade stuff. Cookie cutters, spares for cat drinking fountain. I guess hardened could've worked too. Printed with ColorFabb HT, so it can just go to dishwasher.
