PETG (Polyethylene Terephthalate Glycol-Modified) filament is a popular thermoplastic used in 3D printing, known for its excellent combination of strength, flexibility, and ease of use. It offers good impact resistance and durability, making it suitable for functional parts and prototypes that require toughness. PETG is less prone to warping compared to ABS, allowing for better print quality and reliability during the printing process. This filament has good chemical resistance, making it a suitable choice for applications involving exposure to various substances. Additionally, PETG is often used for producing clear or transparent prints, providing an attractive finish while maintaining structural integrity.
