PET (polyethylene terephthalate) is a thermoplastic polymer used for drink bottles or sailcloths. Mixed with glycol (hence the “G”) exhibits good 3D printing features. PETG filament is resistant to high temperatures and water, presents stable dimensions, no shrinkage, and good electrical properties. PETG combines ABS durability and PLA printability, and it comes as no surprise that it’s frequently chosen by professionals seeking a reliable filament for their projects.
PETG gained a lot of recognition during the coronavirus pandemic because it can be easily sanitized and therefore is useful for medical applications such as face shields.
