With the continuous development of the industry and technology, ASA filament has become a popular choice for many applications. ASA filament has the ability to withstand weather, resist UV rays, and high temperatures. However, is ASA filament toxic? We will explore the truth and important information related to this issue in this article. Let EuroPlas answer this question and learn more about ASA, its benefits, and its applications in the industry and daily life.

1. What is ASA filament?

ASA filament is a type of fiber used in 3D printing. It is made from a thermoplastic resin called ASA, which stands for Acrylonitrile Styrene Acrylate. ASA is a high-temperature-resistant plastic with UV resistance and corrosion resistance.
ASA shares many similarities with ABS plastic with several added benefits. It is stronger, more durable, and has better UV resistance compared to ABS, which is why it is considered one of the best materials for outdoor applications.

2. Benefits of ASA filament

ASA filament is widely used in various applications, from consumer goods manufacturing to industrial products, due to its numerous benefits.

• High UV resistance: ASA filament exhibits high UV resistance, protecting products made from this fiber from fading and damage caused by sunlight. This makes ASA filament an excellent choice for outdoor applications, such as outdoor furniture, awnings, and interior furnishings.
• High chemical resistance: ASA filament boasts high chemical resistance, safeguarding products made from it against corrosion by chemicals. This makes ASA filament an excellent choice for applications in challenging environments, such as chemical plants and wastewater treatment facilities.
• High water resistance: ASA filament has high water resistance, preventing products made from it from being damaged by water. This makes ASA filament an excellent choice for outdoor applications like boats and kitchen equipment.
• High impact resistance: ASA filament offers high impact resistance, protecting products made from it against damage from impacts. This makes ASA filament an excellent choice for applications that demand durability, such as children's toys and sports equipment.
• Durable and resilient: ASA filament is exceptionally durable and resilient, allowing products made from it to withstand various stresses. This makes ASA filament an excellent choice for applications requiring high durability, such as interior furnishings and industrial products.

3. Is ASA filament toxic? 

ASA filament is a type of thermoplastic resin created from acrylic acid and styrene. It possesses properties such as durability, UV resistance, and heat resistance. ASA filament is widely used in 3D printing to produce parts and objects capable of withstanding harsh environmental conditions.

According to research, ASA filament is not considered toxic. However, direct contact with it can lead to skin, eye, and respiratory irritations. When 3D printing with ASA filament, users should take safety precautions such as wearing gloves, a mask, and safety goggles.

When printing with ASA filament, it is necessary to work in a well-ventilated room with a high-quality ventilation system. Fumes emitted from ASA filament can be hazardous when inhaled. These fumes have a strong and pungent odor due to the presence of Styrene in the plastic compound. Inhaling such fumes can lead to health issues like headaches, irritations, and so on.

Therefore, using ASA filament requires a workspace with appropriate ventilation due to the potential for odoriferous fumes. Additionally, users should wear masks throughout the printing process. Workspaces should be equipped with fans or filtration systems to remove fumes, or enclosed with covers to limit the release of fumes.

4. Disadvantages of ASA

• Difficult printing capability: ASA plastic can pose certain challenges during the 3D printing process, such as warping, cracking, and emitting fumes while printing. This is because ASA plastic has a high glass transition temperature, making it less prone to contraction when it cools.
• Higher cost: ASA plastic is more expensive compared to some other thermoplastic resins like ABS. This is due to the higher cost of the raw materials used in ASA production.
• Limited color fastness: ASA plastic can experience color fading over time, especially when exposed to direct sunlight. This is because ASA plastic lacks the UV resistance of some other thermoplastic resins.
