ASA Filament: Advantages of ASA Filament for Outdoor Applications

ASA filament is well-known for its UV resistance and weather resistance, and it performs very well in outdoor 3D printing applications. Among many 3D printing materials, ASA filament has excellent material properties and is widely used, which is why it is increasingly popular among 3D printing enthusiasts. If you are looking for durable 3D printing materials, keep reading as we introduce ASA filament, its material properties, printing parameters, and together we'll explore the applications of ASA filament printing.

What is ASA Filament

ASA (Acrylonitrile Styrene Acrylate), which is a thermoplastic polymer. ASA and ABS both belong to the styrene copolymer family. Similar to ABS filament, ASA filament also has good strength and durability. Compared to other FDM printing materials, ASA filament has particular advantages in terms of resistance to environmental factors, such as temperature, weathering, UV resistance, etc. It is mainly designed to meet the needs of outdoor durability, with balanced performance and various colors, making it a versatile and reliable 3D printing material. One thing to note when using ASA material is that it is temperature sensitive and may cause problems such as warping. Precise print temperature control can reduce the difficulty of using ASA and reduce printing problems. Therefore, for beginners, mastering ASA filament will be challenging.


ASA Filament: Pros and Cons

There are many commonly used materials in the 3D printing field. Their characteristics will provide unique printing effects, differing in the strength, aesthetics, and applicable range of 3D prints. Different types of 3D printer filaments have their own advantages and disadvantages, and users need to choose the appropriate material according to their own needs. The biggest advantage of ASA filament lies in outdoor applications. It is undoubtedly the best choice if weather-resistant 3D prints are needed.

Pros of ASA Filament
  • Outdoor applications
  • Excellent weather resistance and UV resistance
  • Good durability, chemical resistance
  • Thermal stability, diverse applications
Cons of ASA Filament
  • Not environmentally friendly filament material
  • High performance requirements for FDM 3D printers
  • Higher cost than PLA filament

ASA Filament: Properties and Features

ASA filament has three main properties and advantages, weather resistance, durability and thermal stability. Among commonly used 3D printing filaments, PLA, PETG, and ABS are not as good as ASA in temperature resistance. Anycubic ASA filament, for example, has a heat distortion temperature of up to 90°C and is resistant to UV rays, weather and environmental changes. ASA filament is mainly used to make 3D prints that are suitable for outdoor use, which can avoid the problem of ABS that can turn yellow in sunlight and degrade in the long run.

Weather Resistant: The material properties of weather resistance will allow ASA filament to withstand natural environmental changes such as rain, snow, temperature changes, etc. ASA filament is also resistant to UV radiation, making it suitable for 3D printing projects and applications that require exposure to sunlight. In outdoor applications, such as street signs, garden functional accessories and decorations, ASA is an ideal material of choice.

Durability: ASA and ABS are similar in that they both have good strength and toughness. he acrylate component gives ASA filament good impact resistance and can withstand external forces. ASA filament also has chemical resistance, slightly less so than ABS, but stronger than PLA filament. The stable material properties also make ASA more widely used.


Thermal stability: Thermal stability means that ASA filament can maintain stability at higher temperatures without significant changes in properties. ASA filament is an ideal choice for 3D printing projects that require resistance to high temperature environments. But on the other hand, the printing temperature of ASA filament is also higher. Typically, the recommended nozzle printing temperature is 230-250°C and the hot bed temperature is 80-110°C. It is best to follow the printing temperature settings provided by the manufacturer and adjust them according to your own needs. Otherwise, 3D prints are prone to warping, nozzle clogging and other printing problems.
