Tensile Behavior in the Experimental Tests for PETG Specimens Developed with Fused Deposition Modeling Technique

Fused Deposition Modeling is an innovative and cutting-edge manufacturing technology that utilizes layer-by-layer deposition to create 3D parts with diverse applications across various disciplines. However, the knowledge needed to fully understand the effect of printing process parameters on the mechanical properties of printed parts. Therefore, the present-recorded paper addresses the effects of printing parameters such as raster angle direction, layer thickness, and nozzle temperature on the tensile strength of the 3D printed samples using polyethylene terephthalate glycol material. The variables under study are ultimate tensile strength, yield strength, strain at break, and young’s modulus. The results indicate that the raster angle, the layer thickness, and temperature significantly influence the tensile of the printed parts. The higher value of the layer thickness and higher nozzle temperature improve higher tensile strength. The raster angle (0°) benefits ultimate tensile strength, yield strength, and young’s modulus, followed by (0°/90°) and then (−45°/45°) raster angles. However, the raster angle (−45°/45°) resulted in the highest value of strain at break.
