The effect of the powder absorptivity on the molten pool dimensions and thermal behavior of SLMed AlSi10Mg has been investigated using finite element analysis in this paper. A transient three-dimensional finite element model using a moving body heat Gaussian energy source is proposed and two absorptivities with large difference were utilized. The results show that higher value of powder absorptivity will obtain larger molten pool dimensions, higher temperature and lower temperature change rate of the first 4 tracks.
