On the current research progress of metallic materials fabricated by laser powder bed fusion process: a review

Laser powder bed fusion (LPBF) is the most common metal additive manufacturing technique. Following pre-programmed designs, it employs a high-power density laser source to melt pre-alloyed or mixed powders layer by layer, allowing for complex metallic component fabrication. This technique has recently been utilised to produce superior, near-full-density three-dimensional functional parts for various industrial applications. As the LPBF technology matures, ongoing research is being conducted to increase its viability as a sustainable solution in achieving digital transformation in metallic materials and qualifying new metallic materials for digital products. This review focuses on recent developments in the…
