Should one generally use the A350 Enclosure fan for regular PLA prints, or not?
On the one hand I heard that if a layer cools to quickly then the next one might not adhere to it well. On the other hand there are people who even employ parts coolers which are supposed to be very helpful when printing small layer heights.
I have my printer in my garage where presently it might get chilly at night (while printing throughout the night). Inside the enclosure it seems to have a slightly warm temperature.
So again, I would like to know if it matters or if print quality gets affected by the temperature level in the enclosure. If so, please give guidelines.
The way I think of it is as conflicting requirements that have a range of possible solutions.
As temperatures go up layer adhesion increases.
But also as temperature goes up parts can sag.
So for any given print you’ll have to choose based on the particular geometry of that print if a little bit of sag is going to ruin it then you’ll have to turn part cooling on. But understand that there will be less strong layer adhesion.
Parts that are designed to be strong usually do not have very detailed features and are quite simple and there’s really not much that could possibly sag on them, so printing them at higher temperatures is fine with no part cooling. That would not work for a miniature model which would be ruined without cooling.
