In the world of aerospace engineering, where safety and reliability are paramount, even the smallest details can have a significant impact. One crucial aspect that often goes unnoticed is the role that surface finish plays in parts and specimens, particularly those created with Laser Powder Bed Fusion (LPBF) technology. By creating a smooth and uniform surface finish, there is an overall reduction in irregularities, such as roughness, burrs, or surface defects. These irregularities can disrupt the flow of air, leading to turbulence and increased pressure losses.
