What is ASA print filament?

ASA filament (acrylonitrile styrene acrylate) is the perfect all-purpose 3D printing thermoplastic, suitable for many different applications. It has a similar chemical makeup to ABS plastic but offers three improvements: better mechanical properties, superior aesthetics and it’s UV resistant.

What is ASA filament used for?

Acrylonitrile Styrene Acrylate (ASA) is a synthetic, amorphous thermoplastic that works best in material extrusion printing. It is a high impact material that can be used to produce functional parts for automotive applications, electronics, tooling, and more.

Is ASA safe to print?

Just like other filaments, ASA emits dangerous fumes that are smelly and intense during the printing process. The fumes are emitted by the plastic because there is the presence of Styrene. The fumes are a health hazard as they can cause headaches and irritation among other problems.

Is ASA filament waterproof?

Like high resistance to UV rays, and chemicals, ASA is also highly resistant to water. Parts printed with ASA can withstand water exposure for a long time without any damage.

What type of plastic is ASA?

Acrylonitrile styrene acrylate (ASA), also called acrylic styrene acrylonitrile, is an amorphous thermoplastic developed as an alternative to acrylonitrile butadiene styrene (ABS), but with improved weather resistance, and is widely used in the automotive industry.

Is ASA filament easy to print?

ASA can be a very sensitive material to print, so print settings, including temperatures, play a key role in how a print can turn out. You should always default to the settings provided by the manufacturer of the specific ASA filament you’re using.

How strong is ASA plastic?

Some of ASA’s mechanical properties include: Tensile strength, yield: 4750 psi. Tensile strength at break: 4630 psi.

What is ASA used for 3D printing?

ASA, also known as Acrylic Styrene Acrylonitrile, is a 3D printable plastic with properties similar to ABS. It was originally developed as an alternative to ABS that would be more UV resistant by changing the type of rubber that’s used in the formulation.

Does ASA filament need an enclosure?

According to MatterHackers, Simplify3D, and 3D Insider an enclosure is not necessary but highly recommended as ASA, like ABS, is susceptible to drafts and can warp. A heated bed is necessary (somewhere between 90-110 °C), and little-to-no cooling fan used.

What is the difference between PLA and ASA?

ASA 3D prints are durable, tough and suitable for a wide range of applications. The glass transition temperature is also higher compared to PLA and PETG, which gives objects printed from ASA an excellent temperature resistance – there are no signs of deformation up to temperatures near 93 °C.
