Effect of Scanning Methods on Residual Stress Distribution and Thermal-Stress Couple Field During Direct Laser Metal Deposition Shaping

Scanning strategy optimization for the selective laser melting additive manufacturing of Ti6Al4V

“…Amongst these study, the temperature field or stress field was taken as the simulation object combined with different scanning strategies, such as Long-side reciprocating scanning, short-side reciprocating scanning and alternated reciprocating scanning [12], island scanning, snake scanning [13], etc, the influence of scanning strategy on the temperature, stress, and deformation of parts has been studied. Kruth et al considered six different scanning strategies and found that the island scanning strategy would cause less distortion [14].…”
