Bambu Lab PETG-HF Series
PETG HF is a fully optimized PETG filament designed for high-speed printing. With a default print speed twice that of standard PETG, PETG HF elevates your printing efficiency to new heights. It effectively resolves common issues such as oozing and clumping in regular PETG, ensuring smoother and more reliable prints. The new matte finish not only smooths out inconsistent gloss during speed transitions, enhancing aesthetics, but also provides a consistent, uniform appearance.
Compared to PLA, PETG HF boasts superior durability and toughness, making it ideal for manufacturing long-lasting items, improving surface finishes, and reducing production times.

Easier to Achieve Perfect Prints
PETG HF offers the best printing performance among PETG filaments, with greater adaptability to printers and print settings, allowing for ideal print results without fine-tuning parameters. Thanks to advanced formula optimization, PETG HF eliminates oozing and clumping, ensuring smoother prints and sharper details.

Smooth and Soft Texture
PETG HF maintains a smooth texture and consistent gloss at all print speeds, ensuring uniform and clear details with every print.

Suitable for Outdoor Use
PETG HF retains the inherent advantages of general PETG, offering excellent water resistance, UV resistance, and high-temperature resistance. It is stronger and more durable than PLA, with higher temperature resistance, making it an optimal choice for printing outdoor items such as flower pots, bird feeders, watering cans, and car parts. Additionally, it is ideal for outdoor toys that require long-term exposure and can withstand impacts, bumps, and drops.
