A flash-based thermal simulation of scanning paths in LPBF additive manufacturing

During manufacturing by Laser Powder Bed Fusion (LPBF), the laser-scanning path influences the thermomechanical behavior of parts. Therefore, it is necessary to validate the path generation considering the thermal behavior induced by this process to…
