The Effect of a Scanning Strategy on the Residual Stress of 316L Steel Parts Fabricated by Selective Laser Melting (SLM).

As can be seen from the table, for the four samples, σ x values were larger in the lower left corner of the sample, and the stress showed a decreasing trend upward and right, which was due to the scanning start position being located in the left lower corner of the fabricating plane, following the scanning sequence from bottom to top, the left lower part of the produced part presents a larger temperature gradient field, and then it tends to be in a state of dynamic equilibrium.
