Additive manufacturing via material extrusion has attracted significant attention due to its ability to produce complex geometries with low material consumption. However, in this method, the production time and the dimensional accuracy of the parts produced generally include parameters that have opposite effects on each other. In other words, parameter values that increase dimensional accuracy also increase production time. This study investigated how the most important parameters affecting production time, layer thickness and printing speed, affect dimensional accuracy. An experimental design was created using the Taguchi L9 orthogonal array and the dimensions of the cubes produced according to this design were measured using a CMM in the X, Y and Z directions and their dimensional accuracies were evaluated. In addition, contribution of the parameters on dimensional accuracy was evaluated with ANOVA.
