Abstract Scope |
Laser powder bed fusion (LPBF) has proven to be an exceptional technology for the manufacturing of complex and innovative design components. In this study, LPBF was used to manufacture AlSi10Mg alloy with varying laser distance. The microstructure of the samples was characterized using a combination of optical microscopy, SEM, and EBSD techniques. Additionally, image processing with CNN was used to assess the porosity, pore diameter, circularity, microstructure, and anisotropy of the samples. The deep learning techniques optimized melt pool features w.r.t. laser distance. The findings revealed that the printing parameter had a significant impact on the distribution of keyhole, lack of fusion, and gas porosities. Moreover, the CNN models provided a deeper understanding of the anisotropy of SDAS and its relationship with gas porosities. The study demonstrates the potential of LPBF technology and deep learning for the optimization of printing parameters to manufacture components with desired properties. |
