چکیده مقاله
Selective Laser Melting SLM methods is attractingconsiderable interests as it produces parts with superiorquality and it can overcome the geometry complexity Although the SLM method is commonly utilized for thefabrication of metallic components, process parameters mustbe specified in order to create a part with the appropriatemechanical qualities while minimizing the development ofdefects The purpose of this study is to evaluate the influenceof process factors such as laser speed and laser power onresidual deformation and residual stresses by simulatingpowder melting, solidification, and evaporation It aims toprovide more accurate findings by taking evaporation intoaccount in the thermo plastic examination of SLM Thethermo mechanical properties of all five phases powder,melting, mushy zone, solidified, and vapor were consideredto be temperature dependent A finite element FE simulation was performed to numerically investigate theeffects of process parameters on the residual deformations The results revealed that residual deformation stabilizes afterthe second layer and increases with the number of tracks,with the first track having the lowest residual deformationvalues and the fourth track having the greatest The effects oflaser speed and power on residual information were alsostudied
