Evaluating the Mechanical Behavior of Fused Deposition Modeling Parameters of Raster Angle and Layer Thickness Effects on As-Built and Annealed Polymer Associated Composites

Fused deposition Modeling (FDM) is one of the 3D techniques which are mainly used to fabricate the three-dimensional object directly and it is more economical method. The objective of this investigation is to primarily fabricate as-build and annealed polymer associated composites of carbon fiber Polyethylene Terephthalate Glycol (CF-PETG) material by FDM with the effect of different raster angle and layer thickness were consider as the prime parameters. The test specimen was prepared by FDM process with different raster angle (0⁰/90⁰, -45⁰, +45⁰, -45⁰/+45⁰) and layer thickness (100, 400 microns) with other parameters were kept constant. The study of the mechanical properties such as hardness, tensile and impact test of the as-built and annealed CF-PETG were investigated. The best results obtained for annealed specimens printed with raster angle of 0⁰/90⁰ and layer thickness of 100 microns produced more influence in all the mechanical properties. The high strength printed samples were suggested for conventional material replacement.
