PETG is a glycol modified version of polyethylene terephthalate (PET), commonly used in water bottle manufacturing. Filaments that are made from PETG are widely applied in 3D Printing due to their special properties and easy-of-processing. It is a kind of ideal Printing Material with practical application value.
PETG Printing Filaments are commonly used in 3D Printing. As a new type of 3D Printing Material, PETG shares advantages of PLA and ABS, whose printing products have good glossiness, high strength, low warping, smooth surfaces. What’s more, the products are not easy to break and almost no odor during printing.
It is important to note that each material has its unique Features and Application scopes, so users are advised to consider comprehensively based on specific requirements and printer models when choose to use it. Meanwhile, an appropriate settings and adjustment still need to be made according to Printer types and individual needs for the best printing effect when you use PETG Filaments.

Hex Code List

High Strength and Toughness

PETG has a higher strength and toughness than PLA, so its printing objects are more durable.

Better Heat Resistance:

PETG can endure a higher temperature, so it has advantages in applications where there needs high-temperature resistance.

Transparency:

PETG can produce transparent or semi-transparent products which are suitable for projects that need transparent parts.

Chemical Resistance:

PETG has a good tolerance to some chemicals, making it suitable for some special environments or applications that require exposure to chemical substances.

Low Temperature Printing

Compared with other materials, PETG can be printed at lower temperatures where heat damages to printers or printer parts can be reduced.

Low Shrinkage Rate

PETG has a lower shrinkage rate, helping maintain dimensional accuracy of printing objects.

Food Grade Safety

Some PETG materials can be used in food contact applications, such as printing food containers or packaging.
