I am having trouble printing a hollow object using Slic3r. On flat slopes on top, there are gaps that I cannot get fixed. The perimeters of successive layers just don't cover each other.
Cura however adds filament to cover the gaps.
The bottom left bunny is sliced with Slic3r 126.96.36.199. The top right bunny is sliced with Cura 2.5. Take a closer look at the forehead and the back of the bottom left bunny.
I have "extra perimeters if needed" turned on. But turning it off makes no difference. What am I missing?
So far only adding infill and increase the solid top layer count helps to get a closed surface. But then everything gets stiffer. The bunnies are printed with nylon so they are a bit squishy.
The printer settings in both Cura and Slic3r are:
- 0.4 mm nozzel;
- 0.2 mm layer height;
- No infill;
- 2 perimeter walls, and;
- 3 solid top/bottom layers.
