What is the point of the non-hardened 0.4?

Bambu Lab A1 Series

Hi! I noticed in the pack of 3 was included a hardened 0.4, what is the point of the non-hardened then? I though the “hardened” one was a benefit of the more expensive ones

To be a .4 nozzle if you aren’t printing abrasives. My flow calibration works better with the stock stainless than it does with the hardened

oh ok, because heat conductivity you think?

Thermal conductivity in descending order : brass, steel, hardened steel

TBF I do not think thermal conductivit matters much now that we have more powerful heaters in printers. However, there’s still the issue of price, or deliberately shipping with a lower end part in order to be able to sell upgrades.

I would say that thermal conductivity still matters because your thermostat and heater are not inside with the filament. True that the more powerful and efficient the heater, the faster it can heat up and the faster it can adjust but no matter how powerful the heater that heat still has to go through everything to get to where it needs to do its job.

And eried, if you want the best of everything, try a ruby nozzle (assuming they make one for Bambu printers). I have one on my Ender and it is amazing.
