One of the prominent representatives of heat-resistant polymers was the class of Polyethylene Terephthalate Glycol (PETG) with high-strength, but still lightweight. The carbon fiber with PETG (CFPETG) composites also gives even more resistance to heat and chemical, creating it a demandable choice of application in automotive and other industrial components. This paper aims to study the most significant process parameter of FDM technique for different infill density of 25%, 50%, 75%, and 100% at various sliding load condition and sliding distance on wear and friction characteristics of PETG and CFPETG under annealed condition was investigated via dry sliding tribometer apparatus. The trials were done by applying the load of 10N, 20N, 30N, 40N, with a sliding distance of 1000m, 2000m for the time period of 10 min at room temperature and responses such as wear rate and coefficient of friction were recorded for further analysis.
