This orange Polymaker PolyLite ASA filament has a diameter of 1.75 mm. ASA consists of a unique mix of high-quality PLA and PHA. This makes it stronger, harder and less brittle than standard PLA filament. ASA is known for its UV stability and high temperature resistance up to 96 °C. It does not warp and adheres perfectly to the print bed. You can also print ASA a lot easier than, for example, ABS. The ideal printing temperature is 240 to 260 °C. For best results, use a heated bed at 75 to 95 °C.
