Polyethylene terephthalate glycol-modified (PETG) is a thermoplastic polyester known for its strength, flexibility, and ease of use in 3D printing. This material exhibits a unique combination of characteristics including impact resistance, chemical resistance, and temperature resistance, making it suitable for a wide range of applications. A common example would be its use in creating durable prototypes, functional parts, or even containers designed to hold liquids.
The robust and versatile nature of this material contributes to its increasing popularity within the additive manufacturing industry. Its ability to withstand stress and strain without cracking or breaking, combined with its relatively low printing temperature and minimal warping tendency, allows for larger and more complex prints. Historically, materials like ABS and PLA dominated the 3D printing landscape. However, the balanced profile offered by this modified polyester addresses some of the limitations presented by these earlier options, leading to its broader adoption for various applications.
