The effect of line energy density (LED) and wall thickness on the top surface quality of AlSi10Mg sample fabricated by selective laser melting (SLM) has been investigated in this paper. It is observed that the surface morphology has great evolution which the molten track turns to regular and then to irregular with the increase in LED. The line roughness (Ra) and peak height (Rz) decrease first and then increase as the LED increases. The optimal LED for low Ra/Rz increases from 0.1389 J/mm to 0.30 J/mm with the wall thickness increases from 0.1 mm to 2 mm. This work can provide a guide of manufacturing complexy geometrical thin-walled parts with a fine top surface quality.
