Material Profile
ASA (acrylonitrile styrene acrylate) is the UV-stable alternative to ABS. The acrylate component (instead of butadiene in ABS) makes the material resistant to UV radiation and weathering – without compromising mechanical properties.
What ±0.02 mm Tolerance Means
Prusa Research tests every filament spool for diameter consistency at the batch level. The result: fewer clogs, consistent extrusion volume, reproducible wall thicknesses. For us as a service provider, this is directly measurable – reject rates and rework demonstrably decrease.
The measurement records for each batch are retrievable via the QR code on every spool. This traceability meets the requirements of industrial quality management systems.
UV Resistance Compared
| Material | UV stability | Heat deflection |
|---|---|---|
| PLA | Poor | ~60 °C |
| PETG | Medium | ~75 °C |
| ABS | Medium | ~95 °C |
| ASA | Very good | ~100 °C |
| PC | Good (with UV protection) | ~140 °C |
ASA is the only economical FFF option for continuous outdoor use at temperatures up to ~100 °C.
