Why is ASA better than ABS?

In summary, the key differences between ASA and ABS are: ASA is more UV resistant than ABS. ASA is more water-resistant than ABS. ASA has higher temperature resistance than ABS.

Which is better ABS or ASA?

ASA offers high impact resistance, toughness, and weather resistance. ABS offers high impact resistance, toughness, and ease of use. ASA typically comes with a higher price point, while ABS filament spools are generally more affordable. As we said earlier, what it comes down to is what you are using the material for.

Do I need an enclosure for ASA?

According to MatterHackers, Simplify3D, and 3D Insider an enclosure is not necessary but highly recommended as ASA, like ABS, is susceptible to drafts and can warp. A heated bed is necessary (somewhere between 90-110 °C), and little-to-no cooling fan used.

What is better than ABS?

PLA is stronger and stiffer than ABS, but poor heat-resistance properties means PLA is mostly a hobbyist material. ABS is weaker and less rigid, but also tougher and lighter, making it a better plastic for prototyping applications.

How flexible is ASA?

As expected, PLA is really the stiffest with a bending modulus of 3300MPa, next comes ASA with 2300MPa and with only 70% of the stiffness of PLA, PETG is the most flexible material of the 3 with only 1900MPa, really interesting!
