Bambu Lab ASA Gray 1kg – durable technical filament for exterior
Bambu Lab ASA Gray is a top-tier ASA filament designed specifically for
long-term use in outdoor environments. It combines high
resistance to UV radiation, weather conditions, and oxidation with excellent
dimensional stability and toughness, making it ideal for functional and aesthetic parts exposed to sun, rain, and temperature fluctuations.
The Gray color is a versatile, technical-looking shade suitable for
housings, fixtures, brackets, garden and architectural elements, and prototypes where both
durability and a
clean appearance are important.
Key Features
- ASA Material (Acrylonitrile Styrene Acrylate) – technical thermoplastic with high mechanical resistance
- Designed for long-term outdoor use – excellent resistance to UV radiation, weathering, and aging
- Heat resistance approximately up to 100 °C – suitable for parts in warmer environments (e.g., automotive, exterior)
- High dimensional stability – less warping than ABS with correct print settings
- High toughness and strength – suitable for functional and stressed parts
- Optimized for Bambu Lab printers – RFID chip, preset profiles in Bambu Studio, compatible with AMS
- Diameter 1,75 mm, spool 1 kg – standard dimension for modern FDM printers
- Universal Gray shade – technical look, less visible dirt and minor imperfections
Recommended Use
Bambu Lab ASA Gray is ideal for projects where PLA or PETG would not last long enough due to
sun and heat:
- Outdoor components and covers – sensor mounts, cameras, lighting, electronics enclosures
- Automotive and hobby – interior and exterior vehicle mounts, parts for RC models
- Garden and architectural elements – brackets, connectors, decorations, pergola elements, garden furniture
- Functional prototypes – test parts exposed to sun, heat, or moisture
- Technical fixtures and assembly jigs – tools that must withstand workshop or outdoor conditions in the long term
Printing Recommendations (guideline)
Specific values may vary slightly depending on the printer and part geometry; the following serve as a starting point:
| Parameter |
Recommended Value* |
| Nozzle temperature |
approx. 240–270 °C |
| Bed temperature |
approx. 80–100 °C |
| Recommended chamber temperature |
approx. 45–60 °C (enclosed space is an advantage) |
| Printing speed |
rather medium, up to ~250 mm/s for larger parts |
| Cooling fan |
low RPM or off (to limit stress) |
a Printing Notes:
- To minimize warping, an enclosed print chamber or at least protection from drafts is recommended.
- For larger parts, better bed adhesion helps – glue stick, special adhesive agents, or a textured plate.
- For best results, the manufacturer recommends drying ASA before use (e.g., 70–80 °C for several hours), especially if the filament has been open for a long time.
Material Properties (typical Bambu Lab ASA values)
- Material: ASA
- Density: approx. 1,05 g/cm³
- Tensile strength: ~30–37 MPa (depending on direction and print conditions)
- Tensile modulus: approx. 2 000–2 400 MPa
- Elongation at break: ~9 %
- Heat resistance: approximately up to 100 °C (under short-term stress)
These values are guidelines for understanding the material character and may vary depending on specific settings and printing conditions.
Compatibility
- Filament diameter: 1,75 mm
- Net filament weight: 1 kg
- Spool: reusable Bambu Lab plastic spool with integrated RFID chip – Bambu Lab printers automatically recognize the material type and apply the corresponding profile.
- Suitable for Bambu Lab printers (P1, P1S, X1, X1C, A1 etc.) and other FDM printers with correct temperature and printing condition settings.
