Material Properties & Composition
eSun ASA+ is an advanced acrylonitrile styrene acrylate thermoplastic engineered with enhanced mechanical properties, featuring a density of 1.0 g/cm³, tensile strength of 50 MPa, and flexural strength of 35 MPa with excellent rigidity. The material incorporates improved polymer chains that replace butadiene with acrylate groups, resulting in superior UV stability and weather resistance while maintaining ABS-like strength characteristics. Processing temperatures range from 240-270°C with heated bed requirements of 90-110°C, delivering reliable melt flow and dimensional stability.
Applications & Use Cases
This robust filament excels in demanding outdoor applications including automotive components, building materials, electronic enclosures, and marine equipment where prolonged UV exposure and weather resistance are critical. Compatible with enclosed FDM printers, it performs exceptionally well for functional prototypes, outdoor signage, protective housings, and structural parts that must withstand harsh environmental conditions. The material is particularly valued in automotive, RV, and marine industries for exterior components like mirror housings, radiator grills, and sensor enclosures.
Advantages & Considerations
Key advantages include exceptional UV resistance preventing color fading and degradation, superior weather resistance to moisture and temperature fluctuations, and high impact strength with reduced warping compared to standard ABS. The filament produces a professional matte finish with minimal layer visibility while maintaining structural integrity in outdoor environments for extended periods. Users should utilize enclosed printers with controlled chamber temperatures, disable part cooling fans, and ensure proper ventilation due to printing odors, while the material's significant shrinkage requires careful print parameter optimization.
