Cut-section profiles of the outlet channels that are placed 0° and ±40° relatively to the laser axis. (a) Aligning the structures with the laser axis results in symmetric walls. (b,c) Structures placed not aligned with the laser axis (±40°) will be asymmetric where the wall facing the laser will have a steeper slope than the wall facing away from the laser axis. The arrow indicates the direction of the laser. Six structures for each position were evaluated, and all values are in µm.
