What is PETG Filament?

PETG is a co-polymer. The word PET stands for Polyethylene Terephthalate (commonly used in water bottles) and the G stands for Glycol, which is added to give the product extra durability.

What is PETG Filament used for?

PETG is extremely tough, durable, and odorless while printing. When properly set, PETG printed parts can have a very beautiful appearance, similar to PLA, but with much greater strength.

Properties of PETG

It is more flexible than PLA and ABS, but still has a slight softness.
It has very low shrinkage and no warping, making it ideal for printing large jobs.
PETG is very strong and not as brittle as PLA, but it is not as scratch resistant as ABS.
PETG has a high adhesion, so each layer of printing allows the workpiece to adhere well together, resulting in a very strong workpiece!
PETG has very good adhesion to the print bed, so removing the part requires extreme caution.
It has very good resistance to chemicals, including acids, bases and water.
No odor while printing

Polyethylene is typically quite translucent and has a glossy sheen to it, making it ideal for printing projects that require transparency. Many people are switching from PLA or ABS to PETG for printing.

PETG Glass Transition Temperature

The glass transition temperature of PETG is around 80°C, so it is important to decide what material to print with, as this glass transition is very important. PETG's glass transition is lower than ABS's, which has a glass transition of around 105 °C, but higher than PLA's, which has a glass transition of around 55°C.

Below is an example of PETG being printed as a bumper for a small helicopter drone, which requires a certain amount of shock absorption and therefore requires a certain amount of strength.
