Bambu Lab ASA Filament 1.75mm 1KG – UV & Weather Resistant 3D Printing Material
Bambu Lab ASA is a highly durable weather-resistant filament designed for outdoor applications where UV exposure, temperature extremes, and environmental stress are concerns. ASA offers the mechanical strength of ABS with significantly improved UV and oxidation resistance, making it the ideal choice for long-term outdoor projects. Parts remain stable even at temperatures up to 100°C.
Perfect for outdoor signage, garden accessories, automotive trim, functional prototypes, and any application requiring exceptional durability against sun, rain, and temperature variations.

- UV Resistant – Exceptional protection against sun damage and color fading
- Weather Resistant – Withstands rain, humidity, and temperature changes
- Heat Resistant – Maintains shape up to 100°C
- High Strength – Impact resistance comparable to ABS
- Good Stiffness – Maintains structural rigidity
- RFID Enabled – Auto-detection with Bambu Lab printers
Bambu Lab ASA Printing Parameters
| Parameter | Recommended Range | Notes |
|---|---|---|
| Nozzle Temperature | 240-280°C | Start at 260°C |
| Bed Temperature | 90-100°C | PEI plate recommended |
| Print Speed | Up to 300mm/s | High-speed compatible |
| Cooling Fan | 0-80% | Lower cooling reduces warping |
| Enclosure | Recommended | Reduces warping significantly |
| Bed Surface | Smooth or Textured PEI | Clean with IPA before printing |
Drying Requirements
| Method | Temperature | Duration |
|---|---|---|
| Blast Drying Oven | 80°C | 8 hours |
| X1 Series Heatbed | 90-100°C | 12 hours |
| Filament Dryer | 70-80°C | 6-8 hours |
Drying is strongly recommended to prevent poor layer adhesion and brittleness.

ASA Printing Tips
- Use Enclosure – An enclosed chamber significantly reduces warping.
- Dry Before Printing – Moisture causes poor adhesion and bubbling.
- Add Brim – Increases adhesion surface area to prevent warping.
- Ventilation Required – ASA releases fumes; print in ventilated area.
- Annealing Optional – 80-90°C for 6-12 hours improves properties.

Bambu Lab ASA FAQ
Q: Do I need an enclosed printer for ASA?
A: An enclosure is highly recommended. While ASA can be printed on open printers, warping is significantly reduced with an enclosed chamber that maintains consistent temperature.
Q: Is ASA the same as ABS?
A: ASA is a modified version of ABS with an additional acrylate component. This gives ASA excellent UV and weather resistance that ABS lacks, making ASA suitable for outdoor use while ABS is not.
Q: Does ASA require drying?
A: Drying is strongly recommended. Moisture causes poor layer adhesion, bubbling, and brittleness. Dry at 80°C for 8 hours before printing.
Q: Is ASA safe to print indoors?
A: ASA releases fumes during printing. Always print in a well-ventilated area or use a printer with air filtration. An enclosed printer with carbon filter is ideal.
Q: Will the RFID work with my Bambu Lab printer?
A: Yes, Bambu Lab ASA spools include RFID chips that allow automatic detection of material type and settings on X1/P1/A1 series printers.
