Raise3D Premium ASA Filament (1.75mm): Black - 1kg

ASA, or acrylic styrene-acrylonitrile, is an amorphous, opaque thermoplastic that bears structural similarity to ABS. While they can often be used interchangeably, ASA distinguishes itself with a few key features that make it preferable for certain applications over ABS. ASA demonstrates significantly higher resistance to UV light and weathering, making it an excellent choice for applications requiring extended outdoor exposure. Additionally, ASA may offer slightly superior mechanical properties, although it can also be somewhat more expensive. Given the widespread popularity and availability of ABS, it is generally recommended to use ABS unless outdoor exposure is a critical factor.
