PETG stands for polyethylene terephthalate glycol, which is a thermoplastic polyester that provides significant chemical resistance, durability, and excellent impact resistance. It is a material that is commonly used in manufacturing, including 3D printing, food containers, and medical implants. PETG is a food-safe plastic that is fully recyclable. It is both thermoformable and vacuum-formable, and can tolerate a tremendous amount of pressure without cracking. PETG is strong and cost-effective when compared to either acrylic or polycarbonate. Its unique characteristics make it preferable for impact-resistant glazing and high strength display units. PETG is also incorporated in medical implants and prosthesis due to its transparency and durability. PETG is an excellent material to use in modern 3D printers, and is quickly becoming a popular choice among 3D printing aficionados for its odorless process, good layer adhesion, and low shrinkage rate. PETG is different from PET (polyethylene terephthalate) as it includes glycol, giving it different chemical properties than PET. PETG has better shock resistance and is better suited to higher temperatures than PET. Although PETG is recyclable, it is not widely recycled, therefore it is likely to end up at incineration or landfill.
