Material thickness

#1
Hi all,

The vertical layer height is determined by the layer resolution in the slicing program. Does this also apply to the horizontal thickness (assuming the material is extruded as a cylinder/circle)? So for example: with a layer height of 200micron, three vertical shell with create a wall with a total thickness of 600micron. Please advise if this is incorrect.

Thank you.

This is determined by extrusion width. Which should ideally be 1.2 times the nozzle diameter. 600 microns if you are using a 0.5mm nozzle.
