PolyLite ASA is an alternative to ABS with improved weather resistance. Its UV resistance and excellent mechanical properties make it the perfect choice for real-life applications. What is the difference between ASA and ABS? ASA is almost the same as ABS, with 1 major difference and 1 minor difference:The major difference is that ASA is extremely good at weather resistance. (Resistance to UV light and environmental stress cracking)The minor difference is that ASA prints with a nicer matte finish, slightly hiding the layer lines. Printing and Drying Settings?

ASA requires an enclosed 3D printer Yes and no, you can watch the reviews below for more information but the rule of thumb is the bigger your print (more than the size of your fist) the more the enclosure will be required for dimensional stability.
