kisslicer guidelines for shell width/layer height

Hi folks,
I remember seeing somewhere that there are recommendations for choosing
layer height/ shell width based the nozzle size being used, but I can't remember where
I say them.

All I remember is, I think, shell width = 1.6 * layer height?

Can anyone please fill in the missing info?


Many thanks,

Remember only this:

Your slicer will only print even number lines in the shell wall or perimeter (to many names for the same thing). So always calculate your wall thickness based on your nozzle width and number of lines you want to use to create the wall.

For a 0.4 nozzle, it will extrude a 0.46 line. So if you want 4 lines for the wall your number is 0.46X4= 1.84, if you use 2mm it will have gaps in between the lines and your printed part will be weak or will fail while printing.

Hope it helps

As for the other part of the question, always use la layer height smaller than the nozzle, for 0.5 nozzle you can use from 0.1 to 0.4 for 0.4 nozzle 0.1 to 0.3, etc. Deduct 0.1 from nozzle size to determinate the maximum layer height acceptable.

80% nozzle size for max layer thickness. You can get a 0.2mm layer with a 0.25mm nozzle, but you're not going to get a 1.4mm layer with a 1.5mm nozzle, 1.2mm layer at 80%. (just got a 1.5mm nozzle with the new Pico hot end design I am beta testing)

Hey all,
thanks for the info. It has simplified it a bit. But I guess max shell/wall width would be
less 2xNozzle?


Thanks again

Your printed part shell or wall can be as thick as you want, I use Simplify3d for slicing and usually a 3 perimeter shell is plenty for a solid piece.
