We normally print (and recommend printing) in the 0.1 to 0.3mm layer thickness range. However a rather frequent question (or line of questions) is about layer thickness and how thin layers can be printed. MakerGear|Josh sliced up Yoda here at 0.02mm (or 20 microns) layer thickness and gave it a shot on M2. How small is 20 microns? Bigger than a bacteria but smaller than an eukaryote cell!

For scale, a nickel (21mm diameter) would cover the the area shown in this photo. The actual printed model looks way better!! I'd link to the source file, it came from Thingiverse but I'm not sure which of the variants was used. Printed in Black MakerGear ABS.
One of these days, just for the sake of it, we'll print something thinner.
