Abstract: The effect of five factors viz., layer thickness, part build orientation, raster angle, raster to raster gap (air gap) and raster width each at three levels together with their interactions is studied on dimensional accuracy of fused deposition modelling (FDM) build part. Experimental results indicate that measured dimension is always more than desired value along thickness direction but length and width dimensions of test part are less than the desired. Percentage change in length, width and thickness are expressed as grey relational grade for minimization of all responses simultaneously. Optimum factor levels are determined by maximizing the grey relational grade.
