Abstract Additive manufacturing technologies have been effectively useful in a vast range of applications. A popularly known manufacturing technology preferred widely at industries for creating complex structures at low prices is Fused deposition modeling (FDM). In this study, we perceive the response of process parameters on flexural and tensile strength of PETG (Polyethylene Terephthalate Glycol) material fabricated by FDM method. The process parameters considered are Feed rate, infill density and layer thickness. Further, the effectiveness of each parameter is investigated by using ANOVA and drawn out the set of parameters which gives superior results for better mechanical properties of PETG.
