Experience Durability with Shamrock Green ASA Prime
ASA filament (acrylonitrile styrene acrylate) is a thermoplastic 3D printing material that is perfect in many ways and is suitable for many different applications. It has a similar chemical makeup to ABS plastic but offers three notable improvements: better mechanical properties, it is naturally UV resistant, and it simply produces amazing finished prints. Coex 3D offers ASA in the same colors as our ABS giving you 11 colors to choose from and is available in both 1.75mm and 2.85mm diameters in varying spool sizes.
Although ASA can safely be printed using an open bed printer, it is still recommended to print ASA in an enclosed printer which will allow parts to cool slowly and uniformly which helps to prevent shrinkage and warping.
Coex 3D’s ASA products are made with 100% virgin resin and high-quality colorants with no added fillers. All Coex 3D filament is made in our production facility in Green Bay, WI, USA using industrial-grade extruders and laser measuring quality control to ensure quality and consistency with every spool.

Recommended Print Settings
Coex 3D recommends the following print settings when printing with our ASA. Settings will vary depending on your specific printing setup.
- Hotend Temperature: 245 °C - 265 °C (High Speed: 255 °C - 275 °C)
-
Important! This temperature range may seem hotter than you're used to for other ASA filaments. Using 100% virgin resin causes our ASA to require slightly higher printing temperatures.

Important! This temperature range may seem hotter than you're used to for other ASA filaments. Using 100% virgin resin causes our ASA to require slightly higher printing temperatures.
- Heated Bed Temperature: 80 °C - 100 °C
- Recommended Build Surfaces/Adhesives
- Glass Build Surface
- PEI Build Surface
- Magigoo
- Painter's Tape
- Glue Stick
- ABS slurry
- Cooling Fan: Recommended.
- Enclosure: Recomended to prevent warping
- Drying: ASA filament is hygroscopic and will absorb moisture from the air if not stored in a dry environment. If this happens, you may experience under-extrusion/inconsistent extrusion or excess stringing. You may also hear a "popping" sound coming from the hotend during printing. We recommend drying our ASA at 65 °C for at least 3 hours if it has been exposed to excess humidity.
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

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
