COEX 3D ASA Prime (Acrylonitrile Styrene Acrylate) is the ultimate industrial-grade choice for projects that demand uncompromising durability, dimensional precision, and long-term UV stability. Engineered to be the superior successor to ABS, our premium ASA Prime formula bridges the gap between the mechanical robustness of engineering thermoplastics and the smooth, reliable printing experience usually reserved for easier-to-use materials.
This is Natural ASA Prime—a pure, unpigmented, semi-translucent raw filament. Because it contains no added color pigments, this version allows you to see the material’s true structural consistency and internal infill patterns. It is an excellent choice for R&D testing, structural verification, or parts that are intended to be painted, dyed, or post-processed for a specific custom finish. Like all ASA Prime, it is UV-stabilized to resist fading, brittleness, and structural deformation, ensuring that even your unpigmented outdoor prototypes maintain their integrity over time.
Proudly manufactured in our Wisconsin, USA facility using 100% premium virgin resin with absolutely no fillers, COEX 3D ASA Prime guarantees professional, watertight, and highly reliable results every time you print.
Key Features & Advantages
Unmatched Outdoor Longevity: Built to withstand prolonged UV exposure, high temperatures, and moisture without cracking or yellowing.
Precision Manufacturing: Laser-verified diameter tolerance of ±0.03mm ensures smooth, jam-free extrusion for complex geometries.
Optimized Printing Mechanics: Advanced resin formulation significantly reduces shrinkage and warping compared to standard ABS.
Pure Material Purity: Natural (unpigmented) base ideal for structural testing, custom dyeing, or post-processing applications.
Ideal Applications
Functional Prototyping: Visual inspection of internal geometry and structural stress testing.
Outdoor Infrastructure: Signage, garden fixtures, and utility housings where material purity is preferred.
Automotive & Marine: Custom weather-resistant mounts and brackets that may require secondary finishing.
Technical Specifications
Material Type: Acrylonitrile Styrene Acrylate (ASA Prime)
Color Profile: Natural (Unpigmented, Semi-Translucent)
Quality Standards: Virgin resin base, zero fillers, Made in the USA.
Hardware Recommendation: While ASA Prime is easier to print than standard ABS, a heated print bed and an enclosed build environment are recommended for optimal layer adhesion and structural integrity in larger parts.
