An Overview of PETG Filament

PETG is a Glycol Modified version of Polyethylene Terephthalate (PET). It is a semi-rigid material with good impact resistance, but it has a slightly softer surface which makes it prone to wear.

There are several variations of this material in the market including PETG, PETE, and PETT. The tips in this article will apply to all of these PET-based filaments.


  • Glossy and smooth surface finish
