| Abstract Scope |
Laser Powder Bed Fusion (LPBF) has the highest technological maturity and industrial applicability among other metallic Additive Manufacturing (AM) processes due to its advantages such as enabling very complex geometries, a fine feature resolution and a good surface quality. Those benefits make LPBF very suitable especially for heat exchanger applications with intricate features, which are otherwise impossible or very costly to manufacture. To enable complex heat exchanger geometries by LPBF, thin wall manufacturing in various orientations is necessary with a good surface integrity which necessitates process parameters optimized in a different manner than bulk part manufacturing. This study aims at understanding the impact of various process parameters such as scan speed (1050-1950 mm/s) and laser power (280-480 W) as well as scan strategies like contour scanning and blocked path strategy on thin wall characteristics. These characteristics are demonstrated on S-curved walls addressing wall thickness and surface integrity. |
