3D Printing With ASA Filament
ASA Filament (Acrylonitrile Styrene Acrylate) is UV and moisture resistance for demanding outdoor applications.
ASA was created in the 70s by the chemical giant BASF, as an alternative to ABS, with increased resistance to weather conditions. It has exceptional strength and rigidity, high chemical resistance and thermal stability, and, above all, it ages very well and does not turn yellowish with time.
ASA Filament Applications and Guidelines
Applications
- Prototypes requiring UV stability
- Automotive parts
- Outdoor furniture elements
- Precise mold casts
- Sporting items
- Functional prototypes that withstand outdoor exposure
Printing Guildelines
- Typical melting temperature: 220-245°C
- Typical softening temperature: 100°C
- Print surface: Kapton tape, PET, ABS/ASA Slurry
- Bed temperature: 90-110°C
ASA Filament Pros Vs Cons
Pros
- Strong UV resistance
- High impact and wear resistance
- High glass transition temperature
- Warps less than ABS
Cons
- Heated bed required
- Unpleasant fumes
- Limited range of colours
