I see this come up a lot; printing objects with a large hollow area without a vent hole.
Some people claim it is creating suction, but physics tells me that the depth of the hollow would not change the suction tension, only the surface area of the solid part of the layer.
If the piece raises above the surface of the resin, then it should even out between layers.
I am willing to admit I am wrong, but would like to know why.
