Today I wanted to see whats possible on my TAZ 5. So I did a search on Thingiverse for a small and nice object and set my layer height as small as never before.
Layer height: 0.025mm
10 solid layers on bottom, 15 on top
Infill every 5 layers
As expected, it’s no perfect print. Oozing is near to not stopable at this low layer height (lower part of the owls) and the harmonic frequences gave the surface a rough finish (but that makes a nice effect ).
But I was a little bit surprised that it was working at all! Here it is after 3h of printing:
It seems there is a reasonable lower limit at 0.05mm as long as you don’t need to cross the perimeters too often (because of oozing).
