Bambu Lab PETG Basic is a 1.75mm PETG filament sold as a refill without a spool, meant to drop onto a reusable Bambu spool. Its upgraded formula reaches PLA Basic bending strength of 75 MPa while keeping PETG impact toughness at 34.2 kJ/m², so it handles brackets, clips, hooks and outdoor parts that plain PLA would crack. It resists water, UV and heat, and Bambu says it absorbs moisture less than typical PETG, which cuts stringing and gives smoother surfaces. It runs on every Bambu Lab printer and the full AMS series. Owners rate it highly for easy printing and consistent results; the main gripes are that refills need a spool and that PETG still wants drying before long prints.

Bambu Lab PETG Basic is a 1.75 mm PETG filament that combines the bending strength of PLA Basic with the impact toughness of PETG. It suits functional parts such as brackets, wall hooks, clips and holders, as well as outdoor or wet-use prints.
The upgraded formula reaches a bending strength of 75 MPa, the same as PLA Basic, and absorbs more impact at 34.2 kJ/m². It resists water, UV and temperature. It is also less sensitive to moisture than typical PETG, which means less stringing and smoother surfaces.
It works with every Bambu Lab printer and the full AMS series. This version is a refill, so it needs a spool.
