PETG HF filament by Bambu Lab, dark grey, AMS-compatible (refill without spool, 1 kg)

PETG HF filament by Bambu Lab dark grey refill (without reel)nBambu PETG HFnPETG HF is a fully optimized PETG filament designed specifically for high-speed printing. With a default print speed that is twice as fast as standard PETG filaments, PETG HF takes print efficiency to new heights.nnIt effectively addresses common issues such as bleed-through and clumping associated with conventional PETG, delivering smoother, more reliable prints. The new matte finish not only improves aesthetics by smoothing out uneven gloss during high-speed transitions, but also provides a consistently uniform appearance.nnOffering greater durability and strength than PLA, PETG HF is the ideal choice for creating long-lasting products with improved coverage and faster production times.nBuilt for speednTwice as fast as standard PETG*, PETG HF significantly increases productivity without sacrificing print quality.nPerfect prints with minimal setupnPETG HF outperforms PETG filaments in terms of print quality due to its better adaptability to printers and print settings, achieving perfect print results without fine-tuning. Thanks to advanced formula optimization, PETG HF says goodbye to bleed-through and clumping, delivering smoother prints with sharp details.nSmooth, soft texturenPETG HF delivers a smooth texture and consistent gloss at all print speeds, ensuring uniformity and sharp detail on every print.nReady for outdoor usenPETG HF retains the properties of regular PETG while providing excellent resistance to water, UV and temperature. Stronger and more durable than PLA, with higher heat resistance, it is the ideal choice for printing on outdoor items such as plant pots, birdcages, watering cans, and automotive parts. It is also ideal for outdoor toys that require long exposure and are able to withstand shock, collisions, and drops.nAccessory Compatibilitynnnnnnnnnnnnnnnnnnnnnnnnnnnnn

nnnnnnnDownloadsnnnnnnTechnical data sheetnToxicity and safety informationnDirective on the restriction of the use of organic substances (RoHS)nPrinting TipsnDry out before use for higher printing quality. PETG HF must be dried before use and remain moisture-free during the printing process, especially for longer print times (over 6 hours).nnDrying conditions: 65℃ for 8 h in the Blast Drying Oven; 75 - 85℃ for 12 h in the X1 Series Heatbed. For more details please refer to: Filament Drying Recommendations on WIKI. Please note that the spool can withstand the higher temperature for drying on the heatbed.nInstructions for refill replacementn[embed]https://youtu.be/kBTd10EL-Xo?si=0oQejWGW8cXR3tIV[/embed]
