Thank you for your reply,
I have been using the default 10% infill density. I guess I cannot tune it to a lower value, otherwise the walls will become too fragile.

Thank you for your reply,
The thicknesses are in the range of 0.8 to 3.2mm.

Thank you all.
Eventually what I found to have the strongest influence on wall thickness accuracy is the “number of shells” setting, at least in the range of 0.8 to 3.2 mm:
- with “number of shells = 2”, in the range of 0.9 to 1.2 mm, there is a void in the center of the wall, with the efective number of shells being one (i.e. a fragile wall). In the range of 1.3 to 1.6 mm the variation reached 0.3 mm, which I don’t think is acceptable;
- with “number of shells = 1” the variation was about 0.2 mm for a 0.8 mm thick sample. This deviation decreased with the increase of thickness. In the range of 0.9 to 1.2 mm there is infill instead of the void (i.e. a sturdier wall).
To sum it all up, these tests show that for small thicknesses it may be interesting to set “number of shells” to 1. The deviations still occur, but are in general half what they would be with “number of shells” set to 2.
