Siraya Tech - ASA - GF 1.75mm 1 kg

The Siraya Tech ASA-GF filament is the ideal choice for those who want to create components designed to last over time, even outdoors and in extreme environmental conditions. Made of ASA (Acrylonitrile Styrene Acrylate) reinforced with 10% glass fiber, this material offers exceptional resistance to weathering, UV rays, deformation, and impacts, superior even to ABS-GF.

Perfect for professional and technical applications, ASA-GF perfectly maintains its color and mechanical properties thanks to a formulation designed for outdoor exposure: garden furniture, signage, car components, industrial parts, and advanced prototypes are its ideal fields of use. The glass fiber gives the material high rigidity, very low printing deformation (anti-warping), and a smooth surface that can be easily worked or painted in post-processing.

Its heat resistance, with a glass transition of 106°C and an HDT over 90°C, also makes it perfect for parts exposed to heat sources or friction. Excellent dimensional stability even on large prints.

Usage tips

• For best results, use a printer with a closed and heated chamber, a well-leveled bed, and glue/adhesive.
• Before printing, dry the filament if necessary.
• For clean supports, opt for specific removable support materials for ASA.
