This paper presents experimental investigations on influence of important process parameters viz.,laser power,scan speed,layer thickness,hatching space along with their interactions on dimensional accuracy of Selective Laser Sintering(SLS) processed pro-coated sand *** is observed that dimensional error is dominant along length and width direction of built *** parameters setting to minimize percentage change in length and width of standard test specimen have been found out using Taguchi's parameter *** process conditions are obtained by analysis of variance(ANOVA) is used to understand the significance of process variables affecting dimension *** speed and hatching space are found to be most significant process variables influencing the dimension accuracy in length and *** laser power and layer thickness are less influence on the dimension *** optimum processing parameters are attained in this paper: laser power 11 W;scan speed 1200 mm/s;layer thickness 0.5 mm and hatching space 0.25 *** has been shown that,on average,the dimensional accuracy under this processing parameters combination could be improved by approximately up to 25% compared to other processing parameters combinations.
