Modelling of Laser Powder Bed Fusion processes in non-convex geometries with a semi-analytical approach

Laser Powder Bed Fusion (LPBF) is a metal additive manufacturing process in which a three-dimensional object is obtained by selectively melting and fusing a metallic powder with a heat source, such as a laser beam, in successive thin layers. This process allows to create lightweight parts with complex geometry. However, parts created by LPBF...
