Advances in Polishing of Internal Structures on Parts Made by Laser-Based Powder Bed Fusion

With the development of industrial manufacturing, metallic parts with delicate internal structures are in high demand for their lightweight, high cooling efficiency, and superior energy absorption properties. Laser-based powder bed fusion (L-PBF), as an advanced additive manufacturing technology, enables the fabrication of parts with customized internal structures through its layer-by-layer deposition principle.
