Optimised PETG for high-speed printing in red Bambu Lab PETG HF is an optimised PETG filament with a matte surface finish that has been specially designed for high-speed printing. PETG HF has greater durability and toughness as compared to a PLA filament. Thanks to the optimised formulation with better flow properties, the material can be printed with thinner walls and produces more detailed structures.PETG HF has excellent water, UV and heat resistance. This makes the material suitable for printing objects for outdoor use (e.g. flower pots, bird cages, watering cans and car parts). Dry before use! Tip: All printing parameters are embedded in RFID and are read automatically by AMS/AMS lite.
