ASA filament
Resists sun, weather and chemicals; the material for outdoor use.
Most popularWhat is ASA?
ASA has properties similar to ABS but is far more resistant to UV, weather and chemicals. It does not yellow or fade in sunlight and gives a smooth surface finish.
Requires an enclosure and a heated bed.
- Outdoor / UV
- Heat resistant
- Chemical resistant
UV resistance
Does not yellow or fade in sunlight; the right choice for outdoor parts.
Weather
Withstands temperature changes, humidity and rain; keeps its shape outdoors for years.
Chemical resistance
Resists oils, solvents and many chemicals; suitable for industrial environments.
High durability
Heat deflection temperature of 88 °C and a durability score of 10/10; for demanding functional parts.
