RAISE3D [S]5.11.01052A01 Premium Filament ASA UV-resistant, weatherproof, high stiffness, high tensile strength 1.75 mm

ASA stands for acrylic-styrene-acrylonitrile and is an amorphous, opaque thermoplastic that is structurally similar to ABS. In many cases, they are quite interchangeable in their purpose, but ASA has some important distinguishing features that make it suitable for certain applications against ABS. ASA is much more resistant to UV light and weather, making it a better choice for applications with longer outdoor loads. ASA may have slightly better mechanical properties, but may cost a little more in some cases. As ABS is so popular and offers many other options, it is generally recommended to opt for ABS unless outdoor exposure is a problem.
