Siraya Tech - ASA - GF 1.75mm 1kg

The filament Siraya Tech ASA-GF It's the ideal choice for those looking to build components designed to last, 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 impact, even superior 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 use: garden furniture, signage, automotive components, industrial parts, and advanced prototypes are its ideal applications. Fiberglass gives the material high rigidity, very low warping during printing, and a smooth surface that can be easily machined or painted in post-processing.

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