Bambu Filament PETG HF Launches New High Speed

ARSALAN PST COMPLET

Basic Info

Bambu PETG HF is a fully optimized PETG filament designed specifically for high-speedwriting. With a default printing speed that is twice as fast as standard PETG filaments, PET GF takes your printing efficiency to new heights. It effectively addresses common issues such as oozing and clumping associated with regular PETG, ensuring smoother and more reliable prints. The new matte finish not only enhances the aesthetic by smoothing out uneven gloss during speed transitions but also provides a consistently uniform look. Offering greater durability and toughness than PLA, PETG HF is the ideal choice for creating long-lasting items with an improved finish and faster production times.

Data

Nozzle Temperature| 255 °C
Bed Temperature| 70 °C
Printing Speed| 200 mm/s
Infill Density| 100%

• All the specimens were printed at the following settings: Nozzle Temperature = 255 °C, Printing Speed = 200 mm/s, Bed Temperature = 70 °C, Infill Density = 100%. All the specimens were annealed and dried at 75 °C for 8 h before testing. It’s not recommended to anneal prints of PETG HF, because only very limited promotion of properties can obtain while prints with not very simple shape and structure may deform obviously. If you do want to anneal them, the suggested temperature is 75 to 80 °C, and the time is 4 to 8 hours. When drying the filament and annealing the prints, it‘s required to use an oven that has big enough inside volume and can provides even temperature distribution, such as a blast drying oven (forced-air drying oven), and the filament and prints need to be away from the heater, and a microwaves oven or kitchen oven is not compatible, otherwise the filament and prints can get damaged.
