PET and PETG Filament – Durable, Low-Warp, and Easy to Print

PETG (Polyethylene Terephthalate Glycol) is a high-performance 3D printing filament that blends the ease of PLA with the strength and toughness of ABS. It’s ideal for applications that demand durability, light flexibility, and chemical resistance, such as brackets, housings, and mechanical parts.

PETG offers excellent layer adhesion, low shrinkage, and minimal warping, making it suitable for use on both open-frame and enclosed 3D printers. It prints with a glossy finish and is less brittle than PLA, providing improved impact resistance and long-term performance.

Bilby3D stocks a variety of PETG filaments in multiple colours and spool sizes, including options formulated for increased clarity, matte finish, or carbon fibre reinforcement. Every spool is tested for consistent diameter and extrusion quality.

Whether youre printing functional prototypes, protective cases, or durable end-use parts, PETG is a reliable material choice for consistent, high-strength prints.
