Material Name:

PETG (Polyethylene Terephthalate Glycol)

Description:

PETG is a glycol-modified version of PET, widely known for its use in plastic bottles. The addition of glycol prevents crystallization, making the material clearer and less brittle when heated. PETG offers a unique balance of properties: it's stronger and more flexible than PLA, yet easier to print than ABS. It exhibits excellent layer adhesion, low shrinkage, and minimal warping, making it suitable for large prints. PETG is also known for its chemical resistance, transparency, and FDA compliance for food contact in certain grades. Its durability and toughness make it an ideal choice for functional prototypes, mechanical parts, and end-use applications across various industries. PETG's hydrophobic nature reduces moisture-related printing issues, and its glossy finish enhances the aesthetic appeal of printed parts.
