Abstract
In this study, the effect of selective laser melting parameters on the mechanical properties of iron has been experimentally investigated. The mechanical properties discussed in this article are ultimate tensile strength. The selected parameters include the laser power, the laser scanning speed, and the laser hatch distance, and the design of experiments was done by the Taguchi method. By examining the microstructure, the optimal range of the mentioned process parameters was determined to achieve the highest tensile strength. The results show that the optimum parameter levels for the tensile strength include the laser power of 200 watts, the laser scanning speed of 600 millimeters per minute, and the hatch distance of 70 micrometers.
