BigRep ASA is an engineering-grade UV-resistant filament for high-strength and environmentally exposed applications. Designed for industrial and end-use parts, ASA is a strong material with high mechanical resistance, low shrinkage and superior layer adhesion. It is highly suited to applications in automotive, sporting goods, white goods and consumer appliances.
BigRep ASA has been optimized for large-format additive manufacturing and is able to print complex, ready-to-use parts including end-use, factory tooling and functional prototypes with demanding geometries.
Highlights:
- High impact strength
- High weather and UV resistance
- Minimal shrinkage
- High heat resistance
- Easy post-processing
