eem.. As I got it, you are basically telling me that I should not use slicer's infilling at all and model the whole internal structure in CAD program. Yeah, might work, but it's a bit too complex, produce a hugely complex geometry and maybe it even can confuse the slicer.Quote

- model the interior as full solid and make 2 more copies
- use one copy to extrude the walls that you want to be
- intersect above with a second copy - the result will be the shell
- model the structure you want to have in the interior
- use the original of the interior to intersect with the structure
- combine the shell with the interior

Thanks for the answer! I have searched for help on this option and found that:Quote

You could try Cura and in the expert options there is an option to keep open faces.
Doesn't look promising.Quote

"Keep open faces" happens in a step before that [CSG union of everything]. What Cura does at first, is taking a knife and slicing your model into tiny slices. Each slice is a layer as you might understand. But, 3D models are never perfect, so what I end up with is a lot of small line segments in a 2D plane. The next thing I do is joining up small gaps between the line segments, and any line segment that makes a full circle is stored for later reference. Any line segment that fails to make a full circle is normally discarded. UNLESS you have this option checked, then it makes a line from one end to the other to close up the line.
Simple example would be to take a cube, remove 1 side from the cube, save it, load it in Cura. It won't generate any GCode because no slice is closed, unless you check the "keep open faces" then it will effectively fake in the removed surface again.
Results may vary, and it usually works best in combination with "Type-B combine everything".
