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.
As stated from the name, PETG is a modified version of PET (Polyethylene Terephthalate), with the addition of glycol to its chemical structure. This modification makes PETG more flexible and less brittle compared to regular PET. Chemically, PETG is composed of repeating ethylene terephthalate units, with glycol modifiers reducing crystallinity and enhancing durability. This unique composition allows PETG to offer a balance of strength and flexibility, with excellent layer adhesion and resistance to impact, making it ideal for a wide range of 3D printing applications. Additionally, PETG has good chemical resistance and can withstand temperatures up to 80°C.
