eSUN PETG Matte Filament vs Bambu PETG Matte Filament

Both are matte PETG in 1.75 mm on 1 kg spools, and both print on the same machines. Bambu PETG Matte is the safer pick for most shoppers: it is certified low-emission (UL GREENGUARD 2904), rated to +/-0.03 mm diameter, works with every AMS unit, and comes in 8 colors. eSUN's matte PETG is the pick if you want a deep grey frosted look and a spool that is tuned for high print speeds. Reviewers of matte PETG in general praise the layer-line hiding; the usual complaints are stringing and slightly weaker layer bonding than standard PETG, and Bambu's reworked formula is aimed at exactly that stringing problem.

• Choose the eSUN PETG Matte if you want a deep grey frosted finish and a spool built for fast printing on a machine like a Bambu with AMS.
• Choose the Bambu PETG Matte if you want a certified low-emission filament with tight diameter tolerance, full AMS compatibility and a wider color choice.
