Product Details
- SUPERIOR WEATHER & UV RESISTANCE: Outperforms ABS-GF in outdoor durability, maintaining color and physical properties in harsh weather conditions. Enhanced UV protection resists aging and discoloration, ensuring lasting quality for outdoor applications.
- HIGH STRENGTH & IMPACT RESISTANCE: Reinforced with 10% chopped glass fiber for increased strength, stiffness, and impact resistance compared to standard ASA. Ideal for demanding applications requiring durability, especially in high-temperature environments.
- EXCEPTIONAL THERMAL STABILITY: Higher thermal stability than ABS-GF, with a glass transition temperature of 106°C and HDT of 92-97°C (1.8-0.45 MPa). Withstands high-temperature industrial applications requiring heat resistance.
- DIMENSIONAL STABILITY & WARPING RESISTANCE: Enhanced warping resistance ensures superior dimensional stability and minimal warping during printing, making it easier to achieve precise, consistent results.
- OPTIMIZED FOR FDM 3D PRINTING: Print with ease using recommended settings - Nozzle: 250-270°C, Bed: 100-110°C (glass, PEI, or PC film), Enclosure: 60-80°C. Retraction: 1-5mm at 1800-3600mm/min. Dry filament at 70-80°C for 4-6 hours after long-term storage.

Printing Siraya Tech ASA-GF
Siraya Tech ASA-GF in White is ASA filled with chopped glass fiber, and this listing is a 1kg spool. The fibers make parts stiffer and more dimensionally stable than plain ASA, but they are abrasive, so a hardened nozzle is mandatory (see nozzle compatibility below). Few makers publish separate ASA-GF settings, so the ranges below are for plain ASA; expect to print toward the top of them. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.
Ranges checked against Bambu Lab, Prusament and Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our ABS & ASA filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.
Nozzle Compatibility
Glass fiber is abrasive and wears brass (and stainless) nozzles out of round, sometimes within a single spool. Use hardened steel or another wear resistant nozzle such as ruby or tungsten carbide. With hardened steel, start about 5 to 10°C hotter than you would with brass.
Based on Bambu Lab and Prusa guidance. More in our glass fiber filament guide and nozzle types guide.
