On-line melt pool temperature control in L-PBF additive manufacturing

Laser powder bed fusion is a promising additive manufacturing technology which has enabled the fabrication of complex-shape, custom-designed, and cost-effective parts with no need for expensive tools and dies. Despite the numerous advantages of this technology, inconsistency in the microstructure and, consequently, the mechanical properties of the fabricated components in the building direction makes it quite challenging to obtain uniform parts …
