Polymaker ASA (Acrylic Styrene Acrylonitrile) is a thermoplastic material specifically engineered for 3D printing applications that require high weather resistance and durability. ASA is often considered an alternative to ABS due to its similar mechanical properties but with added benefits like better UV and weather resistance.

Physical Properties

  • Density: Around 1.07 g/cm³
  • Heat Deflection Temperature (ISO 75 1.8MPa): 100.2°C
  • Tensile Strength: Around 40-50 MPa, depending on specific formulations

Aesthetic Quality

Polymaker ASA filaments come in a variety of colors and exhibit a matte finish, contrasting the glossy appearance of many other filament types. The material’s high-quality finish makes it suitable for both functional and aesthetic applications, especially for outdoor use where UV resistance is critical.

Durability and Usage

Polymaker ASA is known for its exceptional durability and resistance to environmental factors. It can withstand prolonged exposure to sunlight, moisture, and temperature fluctuations, making it an ideal choice for outdoor applications such as automotive components, garden fixtures, and weather-resistant enclosures.


ASA can be post-processed in various ways to achieve the desired finish or properties. It can be sanded, painted, and glued. However, it’s worth noting that it may require specialized primers or adhesives to achieve optimal bonding.

Environmental Impact

While ASA does offer excellent durability and weather resistance, it is not biodegradable and is derived from petrochemicals. Therefore, it does not have the same eco-friendly profile as materials like PLA. Proper disposal or recycling is recommended to mitigate its environmental impact.

In summary, Polymaker ASA filament provides a robust, weather-resistant option for 3D printing applications that demand high durability and long-term stability. Its ability to withstand environmental factors and its high-quality finish make it a popular choice for both functional and aesthetic outdoor projects.
