PETG: The Material That Combines the Best of PLA and ABS

PETG is a glycol-modified derivative of PET plastic — the same plastic used in water bottles. Because it combines the printability of PLA with the toughness of ABS, it has become the standard material for functional prints in recent years.

Advantages: high impact resistance, 75-80°C heat resistance, excellent inter-layer adhesion, resistance to moisture and chemicals, and availability in food-contact-safe grades. It shrinks very little and does not require an enclosed print chamber.

Disadvantages: it tends to string during printing and its surface finish is not as matte-smooth as PLA. For mechanical parts, outdoor use, containers, and assembly components, PETG is our first recommendation in most cases.
