ASA, which stands for acrylic styrene-acrylonitrile, is an amorphous, opaque thermoplastic that is structurally similar to ABS. In many cases, they are quite interchangeable in purpose but ASA has a few key differentiating features that make it suitable for certain applications over ABS. ASA is significantly more resistant to UV light and weathering, making it the better choice for applications with extended outdoor exposure. ASA can boast slightly better mechanical properties but it can also cost slightly more in some cases. Because ABS is so popular and has many more options, it is generally recommended to go with ABS unless outdoor exposure is a concern.
Nothing will impact your 3D printing results like the kind of filament you use. Good filament is highly consistent in diameter, is wound evenly onto the spool with just the right amount of tension, and will not tangle when being unwound. 3D Universe offers a wide range of high-quality filaments to choose from.
