Print parts of parts one after the other, not by layer
Hello,
I know and use the option to print multiple parts one after the other in their entirety. But what about parts of parts? Look at the attached print. The PLA is probably not as dry as it could be anymore. So the strings reach between all the vertical parts.
If those 4 pillars would be printed one after the other, the stringing would be gone and the print would be faster because the print head wouldn't need to run from corner to corner but could finish its thing in one corner and then move to the next. Their distance looks sufficient for the print head to fit in.
Is this possible?

Is this possible?
If you're up to editing g-code it's most certainly possible, since the pillars don't seem to be close enough to clash into the print head (maybe the pillar are high enough to clash into the x-axis rails though). But just because it's possible doesn't mean it's worthwhile time-wise though.
I don't think we'll see a solution to easily do this implemented in Prusa Slicer anytime soon. The scenario you're showing, i.e. multiple areas that benefit from being printed in sequence but still being far enough away from each other that the print head won't clash with them, is very niche. Again, it's possible to do this by editing g-code but I can only see that realistically being done on production-FFF where you're printing like 100+ of the same component where putting in the time to edit the g-code would be worth it.
Just my two cents!

IMO, it would be a great feature, but I think it would be tough programming challenge. Maybe (banish the thought) even requiring AI!
It would be fairly easy to program, after all it's just sequential printing started higher up ... but it would not have the effect the OP anticipates. instead it would slow printing down...
When a part is narrow the print is deliberately slowed by the slicer to allow time for the extruded filament to cool and set before the next layer is added; even so, when a narrow print looks uneven we will often suggest that several be printed together to allow even more cooling time while the hot nozzle is busy elsewhere. Each of those raised parts would be printed very slowly, before moving to the next instead of at full speed and then cooling between layers while the other high parts were each given their next layer.
This is why there is a setting -
Slow print down if layer print times is below (seconds)
To allow extra cooling time if parts are particularly narrow.
and yes that filament is far too wet.
Cheerio.
