PETG (Polyethylene Terephthalate Glycol) is a popular 3D printing filament known for its excellent strength, durability, and ease of use. It combines the best properties of PLA and ABS, offering high impact resistance, good flexibility, and minimal warping. PETG prints at a temperature between 428°F to 482°F and provides a smooth, glossy finish. It is also resistant to chemicals and moisture, making it suitable for a wide range of applications, including functional prototypes, end-use parts, and mechanical components. PETG's reliability and versatility make it a favorite among both professionals and hobbyists.
