Polyethylene Terephthalate Glycol (PETG) is a semi-flexible, durable material with a glass-like appearance. PETG is most often seen in water bottles, oil containers, and plastic packaging. Unlike PLA, PETG is more flexible and less prone to brittle breaks. PETG also resists shrinking, unlike ABS. These two properties allow PETG to fill a role between PLA and ABS as a strong, easy to print material. PETG’s properties make it ideal if you need an easy to remove raft material, or parts that can take some abuse. For those looking to branch from PLA and create more durable parts, PETG is a good choice.
