We're thrilled to announce the launch of our newest addition to the Siraya Tech Fibreheat family: ASA-GF White! This advanced filament combines the exceptional properties of ASA (Acrylonitrile Styrene Acrylate) with the strength of chopped glass fiber, offering a superior alternative to ABS for outdoor and high-performance 3D printing applications.

ASA-GF vs. ABS: A Clear Winner for Outdoor Use
While ABS has long been a popular choice for functional prints, ASA-GF takes durability and weather resistance to the next level. Here's how our new white ASA-GF filament outperforms traditional ABS:
- Superior UV Resistance: Unlike ABS, which tends to yellow and degrade when exposed to sunlight, ASA-GF maintains its color and mechanical properties even after prolonged outdoor exposure.
- Better Weather Resistance: ASA-GF offers excellent resistance to moisture, heat, and cold, making it ideal for outdoor applications where ABS might fail.

- Higher Heat Resistance: With a glass transition temperature of 106°C and heat deflection temperature (HDT) of 92-97°C, ASA-GF can withstand higher temperatures than typical ABS.

- Improved Chemical Resistance: ASA-GF shows better resistance to various chemicals and solvents compared to ABS.
The Glass Fiber Advantage
The addition of chopped glass fiber to our ASA filament brings several significant benefits:
- Enhanced Strength: Glass fiber reinforcement dramatically increases the tensile and flexural strength of the material, with a tensile strength of up to 45.78 MPa in the XY direction.
- Improved Stiffness: The glass fiber increases the material's modulus, resulting in parts with higher rigidity and less flex under load.

- Better Dimensional Stability: Glass fiber helps reduce warping and shrinkage, allowing for more accurate prints, especially for larger parts.
- Increased Heat Resistance: The glass fiber further improves the already high heat resistance of ASA, making it suitable for even more demanding applications.
- Versatility in Color: White and Black ASA-GF
Our new white ASA-GF filament offers all the benefits of our popular black version, with the added versatility of a clean, bright white color. This makes it perfect for:
- Outdoor signage and displays
- Architectural models and prototypes
- Light-colored functional parts for automotive or aerospace applications
- Any project where a bright, UV-resistant white is desired
Don't forget, our black ASA-GF filament is still available for those projects that require a sleek, dark finish. Both colors offer the same outstanding performance and durability.

Frequently Asked Questions
Is ASA-GF White stronger than standard ASA?
Yes, ASA-GF White is stronger than standard ASA thanks to its glass fiber reinforcement. The added fibers improve tensile strength, flexural strength, and stiffness, making parts more rigid and durable under load.
This makes it a better choice for functional applications where mechanical performance is critical.
Can ASA-GF White be used for outdoor parts year-round?
ASA-GF White is designed for outdoor use and performs well year-round. It resists UV light, moisture, and temperature fluctuations, so it won’t yellow, crack, or lose strength like ABS.
For outdoor signage, housings, or automotive trim, it maintains both appearance and performance over time.
What nozzle should I use for ASA-GF White?
Because ASA-GF White contains abrasive glass fibers, a hardened steel nozzle is recommended. Brass nozzles can wear out quickly, leading to inconsistent extrusion and poor print quality. For frequent use, hardened steel or even ruby-tipped nozzles ensure longer life and reliable performance.
How does ASA-GF White compare to ABS-GF?
ASA-GF White offers better UV and weather resistance, making it ideal for outdoor applications. ABS-GF, while mechanically strong, is less resistant to sunlight and can degrade over time outdoors.
If you need toughness indoors, ABS-GF works well, but for outdoor durability, ASA-GF White is the superior choice.
