AB Additive manufacturing via Fused Filament Fabrication (FFF) has enabled thedevelopment of functional components with customized mechanical properties. In thiscontext, the use of polymers with flame-retardant additives offers an ideal solution forsectors such as aerospace, where fire resistance is a top priority. However, the tribologicalproperties of these materials have not yet been sufficiently studied, despite their relevancein applications subjected to friction or wear. This study analyzes the tribological behavior ofparts manufactured using PETG (Polyethylene Terephthalate Glycol) and flame-retardantPETG (PETG FP) through dry condition Ball-on-Disk tests. The influence of manufacturingparameters such as extrusion temperature and layer height on the coefficient of friction(CoF), surface wear, and roughness is investigated. The results show that PETG FP exhibitsan increased CoF compared to conventional PETG, although it demonstrates more stablebehavior at elevated temperatures. Statistical analysis via ANOVA reveals that materialtype and layer height significantly affect tribological properties, while temperature plays asecondary role. This study provides key insights for the selection of polymeric materials inenvironments with critical functional demands.
