| Abstract Scope |
Achieving high-quality, defect-free components in Laser Powder Bed Fusion (L-PBF) requires precise control over process parameters and a deep understanding of the underlying physical phenomena. This work presents a combined data-driven approach to enhance the prediction and optimization of key outcomes, including melt pool characteristics and part density. By integrating physics-based models with experimental data through a multi-fidelity framework, more reliable predictions of melt pool behavior are achieved. In parallel, machine learning techniques are employed to identify critical process parameters and guide the selection of optimal conditions for attaining high relative density in printed parts. The approach is validated using Inconel 718 and demonstrates strong potential to reduce trial-and-error in process development. This unified framework provides a scalable approach for improving the efficiency and reliability of additive manufacturing. |
