Natural ASA Prime
COEX 3D ASA Prime is the ultimate choice for creators who demand durability, precision, and UV stability in their outdoor prints. Engineered for excellence, our premium ASA (Acrylonitrile Styrene Acrylate) filament combines the ease of printing with PLA and the robustness of ABS, without the drawbacks of either.
Unmatched Outdoor Performance
ASA Prime is specifically formulated to withstand the harshest environmental conditions. Unlike standard filaments that fade, crack, or deform under sun exposure, our UV-stabilized formula maintains color vibrancy and structural integrity for years, making it perfect for:
- Outdoor signage and displays
- Automotive components
- Garden fixtures and tools
- Drone and RC vehicle parts
- Marine applications
Superior Print Quality
- Consistent Extrusion: Precision-engineered diameter tolerance (±0.03mm) ensures smooth, jam-free printing
- Minimal Warping: Advanced formulation reduces shrinkage and warping during cooling
- Excellent Layer Adhesion: Creates solid, watertight parts with exceptional structural strength
- Smooth Finish: Produces professional-looking prints with a premium surface
Our carefully curated palette offers everything from subtle neutrals to eye-catching vibrants—all formulated to maintain their rich color even after years of sun exposure.

Technical Printing Guide - COEX ASA Prime
1. Material Notes
- Keep filament dry - store properly and dry before use
- If needed, dry at 75°C for 3 hours or more
- Enclosure is necessary
- Use Z-offset slightly higher than PLA (+0.05mm)
- Enable "Avoid crossing perimeters" to reduce stringing
- Consider using the "Wipe while retract" option
- Enable "Slow down for small perimeters."
- Print outer walls slower for better quality
- Use a minimum layer time of 30 seconds for small parts
- Consider using "Extra Prime Amount" after retraction

4. Retraction Settings
IMPORTANT: Set travel speed to the maximum your machine allows (200-500mm/s). Faster movements reduce filament oozing time, minimizing stringing.
| Nozzle | Distance | Speed | Z-Hop |
| 0.4mm | 1.0-1.5mm | 40mm/s | 0.2mm |
| 0.6mm | 1.0-1.5mm | 40mm/s | 0.2mm |
| 0.8mm | 1.0-1.5mm | 40mm/s | 0.2mm |
| 1.0mm | 1.0-1.5mm | 40mm/s | 0.2mm |
5. Temperature Settings
Bed Temperature: 80-100°C
- Wash the bed often for good adhesion - Use dish soap and rinse thoroughly to remove oils
- Use bed adhesion products if necessary (gluestick, WELD3D)
- Use brim for tall or large prints
- Keep the ambient temperature stable
Extruder Temperature: 245-265°C
6. Cooling Settings
Cooling Configuration:
-
- First Layer: 0% (fan off)
- General Printing: 100% base fan speed
- Bridges and Overhangs: 100% fan speed
- Layers < 15 seconds: 100% fan speed
7. Troubleshooting Guide
| Problem | Solution |
| Irregular extrusion |
1. Dry the filament 2. Check the extruder 3. Reduce speed |
| Poor adhesion |
1. Dry the filament 2. Use adhesive 3. Adjust the first layer |
| Stringing |
1. Dry the filament 2. Adjust retraction 3. Increase travel speed 4. Check temperature |
PLEASE NOTE: These printing parameters are initial recommendations based on our experience. They may need adjustment depending on your specific 3D printer, environmental conditions, and the geometry of the part you are printing. Use these settings as a starting point and fine-tune them according to your specific needs.
