PETG Filament

PETG Filament: High-quality options for 3D printing

PETG filament is an excellent choice for 3D printing enthusiasts looking for a combination of strength, flexibility and ease of processing. Here are some of the best PETG filaments and their key features available on the market:

Properties of PETG Filament

Strength and durability: PETG (polyethylene terephthalate glycol) is known for its high strength and toughness. It offers excellent layer bonding, resulting in robust and long-lasting prints​.

Printability: PETG filament is relatively easy to print. It is less prone to warping and deformation compared to other filaments such as ABS. The recommended printing temperature is typically between 230°C and 260°C​.

Environmentally friendly: Many PETG filaments are made from environmentally friendly materials. For example, Duramic emphasizes that their PETG filament is made from 100% environmentally friendly materials and contains no recycled waste​ 

Top brands for PETG filament

FIBERLOGY EASY PET-G :  Fiberlogy is a leading manufacturer of 3D printing materials. Their PETG filament is known for its high purity and the strong layer-to-layer bonds it enables. It offers an easy printing experience with minimal warping, tangles or clogging.

Sunlu PETG Filament: Sunlu Filament is characterized by its shiny and vibrant colors. It offers high impact resistance and is known for its ease of use and minimal stringing issues. However, some users report problems with bed adhesion, which can be resolved by adjusting the print settings​ 

Recommendations for printing with PETG

• Printing temperature: A printing temperature of 230°C to 260°C is recommended.
• Bed adhesion: A heated bed can help prevent warping. A print bed made of glass or with a PEI surface can improve adhesion.
• Storage: Since PETG is hygroscopic, it should be stored in a dry environment or in a sealed container to avoid moisture absorption and associated printing problems.

Conclusion: PETG filament offers an excellent balance of strength, flexibility and easy printability. Brands like eSUN, Duramic, and Hatchbox offer high-quality options suitable for various 3D printing applications. By choosing the right PETG filament and following the recommended print settings, you can achieve consistent, high-quality printing results.
