Product description
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 enclosures, fixtures, mounts, garden and architectural elements, and prototypes where both durability and clean appearance are important.
Key Features
- ASA Material (Acrylo Styrene Acrylate) – technical thermoplastic with high mechanical resistance
- Designed for long-term outdoor use – excellent resistance to UV radiation, weathering, and aging
- Heat resistance up to approximately 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, AMS compatible
- Diameter 1,75 mm, 1 kg spool – standard size 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 won't last long enough due to sun and heat:
- Outdoor components and covers – sensor mounts, cameras, lighting, electronics enclosures
- Automotive and hobby – mounts for vehicle interiors and exteriors, parts for RC models
- Garden and architectural elements – brackets, connectors, decorations, pergola elements, garden furniture
- Functional prototypes – test parts exposed to sun, heat, or humidity
- Technical fixtures and assembly jigs – tools that must withstand workshop or outdoor conditions long-term
Printing Recommendations (guidelines)
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 speed or off (to reduce stress) |
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 adhesives, or a textured plate.
- For best results with ASA, the manufacturer recommends drying 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 print direction and conditions)
- Tensile Modulus: approx. 2,000–2,400 MPa
- Elongation at Break: ~9 %
- Heat Resistance: up to approximately 100 °C (short-term load)
These values are indicative for understanding the material's 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 print condition settings.
