This black ColorFabb filament has a diameter of 2.85mm and consists of a unique mix of PLA and PHA. This makes it stronger, harder and less brittle compared to standard PLA filament. In addition, ASA is known for its UV stability and high temperature resistance of 96°C. ASA printed materials are therefore suitable for long-term use. Compared to ABS, printing with ASA is a lot easier. ASA filament does not warp and adheres perfectly to the print bed.
