Study and simulation of different scanning strategies in SLM

In the SLM process, one has to balance between power and scan speed. When small scan speed is used, thermal gradients are important and local solidification can lead to cracks. On the other hand, when high speed is used, the power has to be huge and phenomena due to heat transfer, like delamination or balling, arise. In this paper, we study different possible scanning strategies and we point out those leading to an homogeneous heating of the part until its melting point. The results are compared to numerical simulations.
