@i_like_water i've printed this plane twice using the same filament (3D Lab Print PolyLight 1.0), on my Prusa i3 Mk3S+; once using the pre-sliced gcodes from 3DLP, and once sliced from the 3FM files.

If you're using the gcode or 3MF files provided by 3DLP then the remaining variable is the filament itself.

3D Lab Prints filaments absorb moisture more than many othe PLA formulations. They recommend (on their Discord) to always dry new spools, and store them in a drybox.
