Seeing as PETG is a very strong and durable plastic, it has its own wide range of uses. It is popular amongst those who print mechanical parts because PETG provides a lot more strength and support than ABS and PLA filaments can.
PETG is a transparent kind of copolyester which makes it great for those who have a bit of a creative side. It is great for printing cool looking jewellery such as rings, bangles, bracelets, collars etc. PETG filament is also used widely for packaging and medical purposes as well as industrial.
This particular filament is food and skin safe; therefore it can be used in medical and culinary applications. In medical applications, it stands up to radiation and chemical sterilization techniques without changing its colour.
PETG is not hygroscopic which means that it does not absorb moisture from the air and it is also chemical resistant.
