I'm trying to slice a cylinder which is 10mm in diameter. I want to print it hollow, however when I set the infill to 0% some of the top layer structures are completely unsuported.
You can see the result in my two pictures. The top-layer infill has a hole (1st picture), then the perimeters of the next layer are printed usupported on top of that hole (2nd picture)
What I'd expect is it'd bridge across the perimeters such that there is no hole. Is there a way to do that in slic3r?
Alternatively I could set the infill to a low value (5-10%), but if I do that, it always generates a completly solid infill, quadrupling print time and material usage. When I use a larger diameter object, that doesn't occur, so this is probabbly because 10mm is to small.
So if it's not possible to bridge the top layers, is there a way to disable the solid infill behavior?
Best regards
