Does Layer Height effect print strength?

[Geoff]

Same experience here, my sturdier prints are all 0.1mm or lower. I do think parameter (shell thickness) plays a bigger role though.

Definitely shells. All my quadcopters require 20%infill minimum and 2-3 shells for rigidity. Layer height makes very little difference, but it depends on your force distribution. For a quadcotper arm, I print them flat - so the layers run horizontally, or the same way it's going to sit on the quad. If I was to print them standing up, as in long and tall... they would print layer by layer in the wrong direction...

hard to explain, but print out a small tube. Print one out standing up and the other lying down flat.

The one standing up straight will be more round and look better, but the one you printed laying down witll be 10x stronger to flex and wont snap.

Look at the two pictures. See the cylinder standing up is built with small cricles - these are ok but not as strong as picture 2, where it's layed down in long strips - this is much much more rigid.
