What happens when I print a 0,6mm thick wall with a 0,4mm diameter nozzle?

Question

The wall thickness is 1,2mm but the lip is only 0,6mm thick. How will the 0,4mm nozzle solve this?

Alternatively I could choose a 0,8 mm thick lip, but then the connecting end should be 0,4mm that is too thin.

Answer 1

I'd say you should experiment with Slic3r

it can manage extrusion in very sophisticated way

it can overextrude if you need a line wider than actual nozzle size as same as it can underextrude if needed it can even change extrusion continuously while extruding one line

here are simple examples

i use mattercontrol

take a look here - this is the same object the same layer and the same settings

please notice - this object has wall thicknes exactly 2 times nozzle diam

here is what i get with

• native MatterControl slicer engine which gives this slice

• and Slic3r engine which gives this slice
