ASA: The All-Weather Performer

Introducing ASA, a co-polymer material that's here to redefine your 3D printing experience. ASA was developed as an upgrade to the well-known ABS, one of the go-to industrial thermoplastics. This material offers a range of benefits that make it a top choice for your 3D printing needs. Compared to ABS, ASA has improved UV Resistance, chemical resistance and temperature resistance. Otherwise they are pretty similar.
We stock both ABS and ASA, along with Kevlar filled ABS.

The Strengths of ASA

ASA stands out for its impressive attributes:

Positives:

- Outdoor Weatherability: ASA is your ideal companion for outdoor projects. It retains its gloss and color even in harsh weather conditions. UV-resistant and weatherproof, it's built to last.
- Mechanical Prowess: With high stiffness and impact resistance, ASA outperforms many other plastics in terms of toughness and rigidity.
- High Gloss: Achieve a glossy finish that enhances the visual appeal of your prints.
- Antistatic Properties: ASA naturally possesses antistatic properties, reducing the risk of static-related issues.
- Water Resistance: Known for its resistance to water, ASA keeps your prints intact even in damp environments.
- Chemical Resistance: It can withstand diluted acids and other chemicals, making it a versatile choice.
- Heat Resistance: With a heat resistance of up to 93°C, ASA is a top pick for parts exposed to high temperatures. ABS can withstand temperatures of up to 89C.
- Low Shrinkage: Experience minimal shrinkage during printing.
- Soluble Support: ASA can be dissolved using Acetone, offering practicality as a soluble support material.
- Versatile Bonding: It can be welded, smoothed, glued, and bonded to itself or other plastics using various methods.
- Environmental Toughness: ASA excels in resisting environmental stress cracking and maintains color stability in outdoor applications.
- Low Toxic Emissions: Compared to ABS, ASA emits fewer toxic gases like Styrene during printing.

Negatives:

- Mildly Hygroscopic: ASA can absorb moisture prior to printing, so drying may be necessary before processing.
- Printing Challenges: It can be more challenging to print with ASA compared to some other materials.
- Tensile Strength: ASA has lower tensile strength.
- Chemical Susceptibility: It may degrade when exposed to strong chemicals and acids.
- Warping Tendencies: Prone to significant warping, ASA requires a heated bed and enclosure to combat this issue.

When you're seeking a material that can stand up to the elements, offers high mechanical performance, and retains its vibrant appearance, ASA is the answer. Ideal for outdoor projects and parts subjected to heat and stress, ASA's unique blend of features sets it apart as a valuable addition to your 3D printing arsenal..
