Fused Deposition Modelling (FDM) is one type of additive manufacturing process, where the product is manufactured through layer by layer addition process with high accuracy using computer aided design data. 3-D printing technology is a growing sector of manufacturing, automotive, aerospace and many others. In all these fields it’s proven as the cost effective. In this research work, the 3D printed parts are designed according to ASTM standards and printed from a digital template file using the FDM machine. The material chosen for this 3-D printing parameter optimization is Nylon. In order to improve mechanical properties, tests like Ultimate Tensile Strength (UTS), impact strength, flexural strength and shore D hardness were processed through Taguchi L9 orthogonal array, It have been used with varying the input parameters like fill Density (FD) , Layer Height (LH) and Print Speed (PS). To study the influence of output parameters with respect to input parameters Analysis of Variance (ANOVA) was employed.
