The more plastic you deposit into an overhang, the more mass is being added that will re-heat some of the previous layer, since the newly-deposited plastic can't cool instantly (the fan isn't going to have much effect on the layer below the current one). As each is a fork of the one before it, that makes sense, but it's still a mistake, one that's been handed down like an old pair of shoes. I have no idea why that was changed, and I don't recall when (other than it was a few years ago), but now they all make this same mistake. There was a point some time ago, when Slic3r did not add this extra material. Slic3r, Prusaslicer, and Superslicer all do this as if to make the wall wider, even if the perimeters should already be more than enough, and it seems to apply to all of the configured perimeters, even if only one of them were to theoretically need the extra material.
That may not be too horrible of course, but it still prevents the user from turning out a flawless print. On organic, sweeping curves like in part, that just creates a slight wavy look. To be blunt, this extra material serves no useful purpose, makes overhangs look like crap, slows down the print, and creates waste, which ain't good for the environment or your wallet. To extend the bottom of the vase to the vase hull ( fixes the issue isn't whether infill shows through due to the bottom being thin, it's about the material that's being added into overhangs with otherwise perfectly reasonable settings i.e. The thin walls are newly enforced to be disabled in spiral vase mode,Īnd the "ensure vertical shell wall" is enforced in spiral vase mode If the spiral vase mode is active (removes various unwanted infillĪlong the vase walls), and the last bottom solid layer is switched The infill is newly calculated only for the bottom solid layers These two changes solve #3595 and similar.
