When it comes to 3D printing, choosing the right filament material is crucial for achieving the desired results.
Two popular options in the world of 3D printing are PETG and ABS filaments. In this article, we will compare PETG and ABS filaments, including their properties, printing characteristics, applications, and considerations.
We will also explore how Sunlu Filament, a reputable brand in the industry, offers PETG and ABS filaments that meet high-quality standards.
PETG Properties
- PETG (Polyethylene Terephthalate Glycol-Modified) is a thermoplastic polyester material known for its durability and strength.
- It offers excellent impact resistance, making it less prone to cracking or breaking compared to other filaments.
- PETG has good chemical resistance, making it suitable for applications that involve exposure to chemicals and containers for food, even medical devices and medical implants.
- PETG is a hygroscopic material with a maximum water content of 0.8%. More the 0.5% of PLA.
- Sunlu offers high-quality PETG filaments that provide consistent performance and reliable results.
ABS Properties
- ABS (Acrylonitrile Butadiene Styrene) is a popular thermoplastic known for its strength, Stiffness, and heat resistance.
- It offers good impact resistance and can withstand higher temperatures compared to PLA filament.
- ABS has excellent mechanical properties, making it suitable for functional parts and prototypes.
- Unlike most other 3D printer filaments, the parts printed by ABS are very easy to machine like drilling.
- ABS is a hygroscopic material with a maximum water content of 1.8%. More the 0.8% of PETG.
- Sunlu provides ABS filaments that meet strict quality standards, ensuring optimal printing performance.

PETG vs ABS
Where should I use PETG and ABS?
PETG Filament is commonly used for a wide range of applications that require durability, impact resistance, and chemical resistance. It is an excellent choice for functional parts, prototypes, and mechanical components. PETG's resistance to water and UV radiation also makes it suitable for outdoor applications.
On the other hand, ABS Filament is widely used in industries such as automotive, aerospace, and engineering. Its strength, heat resistance, and excellent mechanical properties make it ideal for functional parts and prototypes that require high mechanical strength and dimensional stability. With excellent electrical insulation, ABS can be used in electric products.ABS is also well-suited for post-processing techniques such as drilling, sanding, painting, and acetone smoothing.
Something to consider
When working with PETG filament, there are a few considerations to keep in mind. PETG can be more prone to stringing and oozing during printing, so it's important to fine-tune retraction settings and cooling to minimize these issues. Additionally, PETG may require slightly slower print speeds compared to ABS to achieve optimal results. It's also worth noting that PETG can be slightly more expensive compared to other filaments.
ABS filament has its own set of considerations. ABS has a higher tendency to warp and shrink during printing, so proper bed adhesion techniques are necessary. This may include using a heated print bed, adhesive, or even an enclosure to maintain a stable printing environment. It's important to ensure good ventilation when printing with ABS, as it can emit potentially harmful fumes. ABS is not suitable for outdoor use, sunlight and water will make ABS brittle. Additionally, ABS can be more challenging to post-process due to its higher hardness.
PETG and ABS filaments are both excellent choices for 3D printing, each with its own unique properties and characteristics. Sunlu Filament offers high-quality PETG and ABS filaments that meet industry standards, providing consistent performance and reliable results. Consider your specific requirements, printing capabilities, and post-processing needs when choosing between PETG and ABS filaments.
With Sunlu Filament, you can trust that you are using filaments that deliver exceptional printing experiences and high-quality print.
