From functional prototypes to production-ready parts, ASA delivers reliable results that hold up to the elements.
What Is ASA Filament?
ASA filament is a high-performance thermoplastic engineered to resist sun, wind, rain, and time. It’s often seen as the tougher, more weatherproof alternative to ABS filament, offering similar strength and durability but with improved resistance to UV degradation and environmental wear.
It’s widely used in automotive parts, enclosures, outdoor signage, brackets, and drone components, any application where longevity and strength matter.
Key Benefits of ASA Filament
If you’re printing parts that need to function outside or in harsh environments, ASA is a smart material choice. Here’s why professionals turn to ASA:
• UV Resistance – Won’t yellow or become brittle over time in direct sunlight.
• Excellent Mechanical Strength – Comparable to ABS, with greater weather resilience.
• Chemical & Heat Resistance – Performs well even in tough industrial settings.
• Matte Surface Finish – Produces professional-looking prints with reduced glare.
• Minimal Warping – Better printability than ABS with good first-layer adhesion.
Whether you're building rugged prototypes or final-use parts, ASA filament gives you long-term performance in real-world conditions.
Print-Ready Performance for Modern Machines
ASA runs smoothly on most enclosed 3D printers and performs exceptionally well with heated beds and active cooling. It's also compatible with multi-material setups like the Bambu Lab AMS system, offering even greater control for technical prints that require structural supports or dual-material workflows.
Pair ASA with a hardened nozzle for extended use, especially if you're working with carbon fibre-infused variants.
