Can someone help with the name of the issue causing those bubbles on the hull? This is something I observe consistently on my 3d prints for a while now. I always affects only one side of a model and comes in different shapes for different geometries. My printer: Ultimaker S2+ (network, air filter) Materials: Blue blue models are PLA, White is PETG (both from Ultimaker) ** Pleae ignore the white model bottom layer, this is just purely torn adhesion layer, the model is flat and the letters on the bottom are readable.
