Another test print:
Something weird going on here, on the back of the head:
Those surface irregularities aren’t part of the model, as far as i can tell, and aren’t layer shifts.
Maybe the geometry was screwy.
50 um seems less overexposed than 100 um, but i have no measurements or quantifiable tests yet.
Again, i’d say the resolution is definitely not the problem, nor the laser spot size.
Edit: Apologies for the ugly fingernails.
