Polyethylene Terephthalate Glycol, PETG
PETG is a clear and durable amorphous thermoplastic material that is excellent for tubing or profiles.
PETG is moderately priced and is commonly used as a filament for 3D printers.
PETG is the glycol modifier when introduced to polyethylene terephthalate, it strengthens and enhances its durability. PETG is FDA-certified, which means it can be used to construct food storage containers, packaging, and even water bottles. It is also frequently used in robotics and electronics.PETG has a light and pliable build, while also being resistant to impact. Due to its high light transparency, PETG is widely used in storefronts. Its main downside is its lack of UV resistance; leaving PETG sitting out in the sun for long periods can cause it to melt and warp. PETG’s ability to form various shapes and maintain a rigid structure once it has dried makes it shine in 3D printing. PETG is also very easy to sterilize. For this reason, printed PETG implants and devices are common in the medical field. PETG is more cost-effective than polycarbonate.
PETG is stronger than acrylic but is also more prone to scratching. Because it is thermoplastic, it is highly sought after as a recyclable material.
