stands for Acrylonitrile Styrene Acrylate filament.
It is a type of 3D printing filament that is commonly used in Fused Deposition Modeling (FDM) 3D printers. ASA filament is a variant of ABS (Acrylonitrile Butadiene Styrene) filament and shares many of its properties while offering some improvements.
ASA filament is known for its durability, UV resistance, and good mechanical properties. It is often chosen for outdoor applications or projects that will be exposed to sunlight for extended periods. ASA has better resistance to weathering, such as UV radiation and harsh weather conditions, compared to standard ABS filaments. It also has improved chemical resistance and retains its color and mechanical properties over time when used outdoors.
Some properties of ASA filament include:
UV Resistance: ASA filament does not degrade or become brittle when exposed to sunlight for extended periods, making it suitable for outdoor applications.
Durability: ASA filament is known for its impact resistance and toughness, making it suitable for parts that need to withstand mechanical stress.
Chemical Resistance: ASA filament is more resistant to chemicals and solvents than standard ABS filament.
Good Surface Finish: ASA filament has the ability to produce parts with a smoother surface finish compared to ABS, which can be useful for aesthetic purposes.
High-Temperature Resistance: ASA filament has a higher glass transition temperature (the temperature at which it starts to soften) than ABS, allowing it to withstand higher temperatures without deforming.
Easy to Print: ASA filament has properties similar to ABS, making it compatible with many FDM 3D printers and easy to print with.
However, it's worth noting that ASA filament can be more challenging to print with than PLA due to its tendency to warp and its higher printing temperature requirements. Adequate bed adhesion and an enclosed printer environment are often recommended to minimize warping.
In summary, ASA filament is a popular choice for 3D printing outdoor and mechanically demanding parts due to its UV resistance, durability, and improved mechanical properties when compared to standard ABS filament.
