Enhancing the Best of Both Worlds: ASA Fuses Thermal and UV Resistance in a Single Material

ASA stands out as an extraordinary 3D printing material, ingeniously merging top-notch thermal and UV resistance properties. This fusion results in a material that excels in strength, durability, and longevity, outperforming its counterparts in challenging outdoor settings. Furthermore, ASA's impressive temperature resilience renders it the go-to choice for fabricating components required to operate in confined car cabins or other high-temperature environments. Rest assured, when the sweltering summer sun bears down, ASA remains unyielding, preserving its structural integrity.

The true game-changer for ASA, however, lies in its unparalleled UV resistance. While other 3D printing materials are prone to color alterations and mechanical property deterioration after extended outdoor exposure, ASA boasts a UV inhibitor that circumvents such damage. Consequently, components printed with PRO Series ASA maintain their strength and aesthetic attributes for years, even under the most severe outdoor conditions.

In summary, ASA heralds a substantial breakthrough in 3D printing material applications, delivering a potent blend of robustness, temperature resistance, and UV resistance. With ASA at your disposal, you can craft high-caliber, enduring components that withstand the test of time, making it the optimal material choice for a diverse array of applications.

How to succeed with ASA

To achieve high-quality 3D prints with ASA, you need to follow some best practices:

1. Bed Adhesion: ASA requires a heated build plate to promote good adhesion, typically around 90-110°C. You can use a build surface like LayerLock PEI, BuildTak, or Glass with a layer of adhesion promoter such as Magigoo or Nano Polymer Adhesive. Ensure that the bed is level before printing.

2. Print Temperature: ASA requires a printing temperature of 240-260°C, which is higher than PLA or ABS. A high-quality all-metal hot end is recommended, as ASA will overheat and destroy a PTFE-lined hot end.

3. Cooling: Unlike PLA, ASA requires minimal cooling during printing to prevent warping or cracking. However, you can use a small amount of cooling to prevent sagging in overhanging sections.

4. Enclosure: ASA is prone to warping, especially when printing large parts, so it's essential to print in an enclosed area. A printer enclosure helps maintain a consistent temperature and prevent drafts from cooling the print too quickly. Remember to leave your printer closed up when a print finishes to let the part fully cool in order to avoid warping and splitting.

5. Post-Processing: ASA can be sanded, painted, or even vapor smoothed with acetone to smooth out the surface finish. However, be cautious of the fumes when using solvents and use appropriate protective gear.

By following these tips, you can produce high-quality, durable prints with ASA that can withstand high temperatures and prolonged outdoor exposure.
