This simulation is looking at a L-PBF process in which the laser transverses the substrate in zigzag pattern. The remelting that occurs between tracks can influence the microstructure of the solidified metal, so it is important to understand how to optimize hatch spacing and scan strategy to achieve desired temperature gradients and cooling rates. FLOW-3D AM provides for melt pool scale process analysis to fine tune these influencing parameters.
