| Abstract Scope |
Laser powder bed fusion of high-performance aluminum alloys requires precise control of the printing process parameters to achieve consistent density, microstructure, and functional performance. This study investigates Constellium Aheadd CP1 aluminum alloy produced using different parameter sets such as laser power, scan speed, hatch spacing, and volumetric energy density. Initial characterization focuses on correlating processing conditions with density, Vickers microhardness, chemical uniformity, thermal conductivity, and microstructural features observed on sectioned build specimens. This initial characterization relates the printing process parameters in terms of composition, internal defects, melt pool morphology, porosity-related scatter, and process-dependent property response on the manufactured samples. These results provide a foundation for physically informed processing-structure-property relationships and future machine learning models for CP1 additive manufacturing optimization. |
