Layer Height – This parameter tells the slicing engine how thin to make the layers when it
slices up the model as I described earlier. A good default layer height is 0.2 or 0.25mm. The lowest
practical layer height with a 0.5mm nozzle is 0.1mm. You can go lower than that, but it requires a
smaller nozzle diameter. You can also got a lot thicker, but that requires a larger nozzle. If you change
the Quality from Standard to Coarse or Fine, you'll notice how the layer height changes.
Here's what the Coarse, Standard, and Fine layer heights look like when printing the little test
cube in ABS plastic.
Fig. 5.1-3: Layer height examples.
Starting from left to right, the layer heights are 0.1mm, 0.2mm and 0.3mm. You'll notice that
the top layer on the 0.1mm print is kind of ratty and torn up. This is because the number of top layers
is set to 3. This is perfectly ok with thicker layer heights, but it should have been set to at least 5 for the
0.1mm layer height that the Fine setting uses. You'll learn how to tweak that in a little bit.
You can see how the smoothness of the sides decrease as the layer thickness increases. If you
want to print something really quick, you could go up to a 0.35mm layer height. I wouldn't recommend
anything over 0.40mm if you're using a 0.5mm nozzle however.
Fill Density – This parameter controls how solid your
printed part is. The number is a percentage, from 0 (totally
hollow) to 1 (totally solid). The default fill density (also known as
"infill") is 0.2 or 20%. The image below shows what that looks
like inside our little test cube.
You can tweak the infill to get a more robust or a lighter
part. For most prints, 20% is a good infill value.
Later on I'll show you how to change to a different infill
pattern. The one shown on the right is the Triangle pattern.
