ASA White Granules

ASA is a thermoplastic created to be similar to ABS, but with better weather resistance. ASA’s combination of high strength and flexibility along with its superior UV resistance makes it ideal for printing objects which may be used in the outdoors or in industrial settings. Due to its high glass transition temperature, a heated bed is required to successfully print with ASA. For the best results when printing with ASA, a fully enclosed print bed recommended.
