Abstract Scope |
Laser powder bed fusion (L-PBF) is one of the well-established and widely used metal additive manufacturing technologies in the market. The technology has been under rapid growth and profound advancement. However, the uncertainty and variability in the quality of produced parts are still of major concern. Understanding the melt pool dynamics and morphological variability is important to determine process parameters for the enhancement of mechanical properties and microstructural control. In this work, we characterize and explore the variability in the melt pool by utilization of high-speed imaging. Quantification of the melt pool dynamics and morphological variation is performed with different combinations of process parameters. Furthermore, we study the correlation between the process parameters and the variation in melt pool dimensions and shape attributes. |
