However , it is extremely challenging to predict distortion of a practical SLMed part if each single track is taken into account by using the conventional modeling methods The complex multiphysics phenomenon such as fluid flow in the melt pool , phase transformation during cooling , and resulted anisotropic properties further complicate this issue .
