Farbman et al. conducted a detailed tensile testing study on 3D printed PLA test specimens. Mechanical tests were conducted according to ASTM code B557-06 at a crosshead velocity of 3 mm/min at a maximum load of 1000 N. Data from the experimental stress–strain curve obtained in ref [ 28 ] was extracted using GetData Graph Digitizer [ 29 ].
The fused filament fabrication (FFF) is one of the most common forms of 3D printing with many hobbyists and as well as professional printers adopting this technology. With numerous printing parameters available for each print, having the knowledge to optimize the printing process to obtain a custom mechanical properties is clearly advantageous. This .Where:-Epsilon is the elongation (Length / original Length) no unit – Sigma is the stress in PA or PSI – F is the force in N or lbf – s is the transverse section in m² or in² Applying a 400Kilo-force (4000N) to a 2cm radius (0.00126 section) 2 meter long steel rod with a Young’s modulus of 200 GPa, the rod will deform off 4000/(0.00126* 200.000.000)=0.016 and the rod will now measure .

Despite the potential attraction of PETG in the 3D printing industry, very few studies have investigated its mechanical properties, such as toughness, tensile strength, elongation at break, yield strength, and tensile modulus, which would then lead to the development of more reliable standards for testing and inspection. All the tensile test specimens were printed under FDM-based 3D printer (Dreamer). Figure 2 a, b shows the printing process of tensile test specimens using the Dreamer printer. Each specimen was printed with different print parameters like infill pattern, infill density, nozzle temperature and layer thickness [ 15 ].
