Optimization of the Fused Deposition Modeling Parameters Using Definitive screening design

Additive Manufacturing offers flexibility in customizing, designing, minimizing waste, faster prototyping and manufacturing complex profiles. The process parameters play a crucial role in the mechanical strength of the 3D printed product. The present research aims to investigate the impact of various 3D printing process settings on the hardness of PLA copper composite. The results of selecting terms with significant effects on the response show that all the factors studied present such effects. Indeed, the analysis of the final screening plans showed that the most influential factors are the filling density and the thickness of the layer for the Flat and Edge positions. The printing speed influences the hardness of the samples in its quadratic form while it itself has no influence. All the factors adopted are influential in their different forms.
