Evaluation of the Mechanical Strength of Polyethylene Terephthalate Glycol(PETG) Filament and Comparison with PLA and ABS Filaments for Use in۳D Printing Technology: Review of Controlled Parameters for ۳D Printing

۳D printing technology is considered an additive manufacturing method that enables the creation ofcomplex structures at relatively low cost and within a relatively short time frame. One of the mostwidely used types of ۳D printers is Fused Deposition Modeling (FDM), which utilizes polymerfilaments as consumable materials. In addition to PLA and ABS, one of the thermoplastic polymersused for making FDM ۳D printing filaments is Polyethylene Terephthalate Glycol (PETG).Mechanical properties of polymers are typically evaluated through tests that assess attributes such asstrength, elasticity, viscoelasticity, and anisotropy. In this study, PETG polymer is identified usingFT-IR and ash content determination tests, and its mechanical properties are examined and comparedwith those of PLA and ABS filament. PETG filament exhibited an increase of ۵.۲۲% in max stressand ۳.۴۴% in max strain compared to PLA filament and decrease of ۱۸.۴% and ۴۴% compared toABS filament
