Gaps in thin walls

Printing an object with a nozzle, which is only a few times smaller than the thickest wall, it might be that the slicer leaves a gap in the middle. For example: the wall is 1.5mm, and you are going to print with an extrusion width of 0.6mm, you need to advance some slicer settings for a solid print without gaps. For this reason, adjust the thin wall behavior and/or the extrusion width in your slicer.

Gaps can occur in the slicing process if the diameter of the wall cannot be divided precisely trough the diameter of the nozzle. The place between, would be free. To avoid gaps in thin walls, choose the thin wall settings. If your slicer do not have this option, vary the extrusion width, and the diameter of internal and external perimeters.
