In contrast, ABS tends to fade and degrade when exposed to UV light, making it less suitable for outdoor use. If you’ve ever noticed an ABS print turning yellow or becoming brittle, it’s due to its poor UV resistance.
For projects requiring longevity and sunlight exposure, ASA emerges as the clear winner.
Chemical Resistance
ASA also excels in chemical resistance. It withstands a broader range of chemicals, including:
- acids
- bases
- oils This makes it suitable for more demanding environments. If your project involves exposure to harsh chemicals or solvents, ASA is more likely to maintain its integrity and performance.
ABS, on the other hand, has a more limited range of chemical resistance. While it performs well in many basic environments, it may not hold up as well when exposed to more aggressive substances.
This makes ASA a better choice for applications where chemical resistance is a priority, especially when considering abs and asa. Additionally, ASA is more resistant to harsh chemicals than ABS.
Temperature Resistance
In terms of temperature resistance, ASA is again more robust. With a heat deflection temperature of approximately 86°C, ASA maintains its structural integrity better under high temperatures compared to ABS, which can only withstand up to 81°C.
Thus, ASA is suitable for applications that need thermal stability. Both ASA and ABS have specific bed temperature requirements for optimal printing, with ASA typically requiring a higher bed temperature to ensure good adhesion and minimize warping.
Paying attention to temperature settings, including the wait time and log of adjustments, is key to achieving high-quality prints with both materials that stick well.
