ABS vs ASA

 

ABS (Acrylonitrile Butadiene Styrene) and ASA (Acrylonitrile Styrene Acrylate) are two popular thermoplastics used in 3D printing. They both have their unique properties and advantages, making them suitable for different applications. In this article, we'll explore the key differences and advantages of using ABS versus ASA.

 

ABS Filament

ABS is a widely used thermoplastic that's known for its toughness, durability, and heat resistance. It's commonly used in automotive parts, toys, and electronic housings. ABS filament is a popular choice for 3D printing due to its high strength and ability to withstand high temperatures.

 

ABS has a high glass transition temperature (Tg) of around 100°C, making it suitable for applications where the printed part will be exposed to high temperatures. Additionally, the durability of ABS makes it ideal for applications where impact resistance is crucial.

 

However, ABS does have some drawbacks. It's challenging to print, and it requires a heated build plate to prevent warping and cracking. ABS also emits a strong odor during printing, which can be unpleasant for some users. Additionally, ABS is not UV resistant and can be affected by sunlight over time.

 

ASA Filament

ASA is a modified version of ABS and is a popular choice for outdoor applications. ASA has similar properties to ABS, but it's more resistant to weathering and UV exposure. It's commonly used in outdoor furniture, signage, and automotive components.

 

One of the main advantages of ASA is its weather resistance. It has a high resistance to UV exposure and weathering, making it ideal for outdoor use. ASA also has a high Tg of around 97°C, making it suitable for applications where heat resistance is required. Additionally, ASA filament is easier to print than ABS. It has a lower tendency to warp and crack, and it doesn't emit as strong of an odor during printing.

 

Despite these advantages, ASA filament is more expensive than ABS, making it less suitable for low-cost applications. ASA is also not as strong as ABS, making it less suitable for applications where high impact resistance is required.

 

Which One Should You Choose, ABS or ASA?

Choosing between ABS and ASA ultimately depends on your needs and preferences. If you're looking for a strong and durable material for high-temperature applications, ABS may be the right choice. If you need a material that can withstand outdoor weather conditions and UV exposure, ASA may be the better option.
