3D printing mozzle distance

[RononDex]

This is a question I have been strugling to find an answer for some time now.

 

Generally it is said, that the mozzle distance from the printing bed should be around 0.1mm (thickness of an office paper).

Now does the optimal distance vary with the layer height? For example if I print with 0.08mm thickness should I then lower the distance just a tiny bit?

 

I found the optimal distance is, when the filament gets spread out a bit, so that the lines get a bit thicker. This makes it easier to create solid layers that are actually solid, and have no gaps between the lines.

So when I know set the layer height down to 0.08mm it will logically have a lower material flow when printing, because it needs less material for thinner layers. Logically I would have to reduce the mozzle distance to the bed just a litte, so the lines have the same width as for example with 0.1mm layer height?

I'm pretty sure my ultimater will print it's first layer at .3mm or something a little thicker, but the layer height is how much your z axis moves after each layer.

As for the material flow, do some experimenting, but I would expect you would have to print a little bit slower (maybe 5-10mm/s slower, it depends on your machine and material).
