Top 5 ASA Filaments for 3D Printing: Unraveling the Best Picks!

ASA is a versatile thermoplastic apt for 3D printing. Numerous enthusiasts are eager to print with top-notch ASA filaments but are in a dilemma about which brands to pick. As Carolina, a tech trainee with a penchant for writing, I’ve delved into some top-rated ASA filaments that the community adores, hoping you find your perfect match. ASA filaments boast robustness and superior resistance to moisture and UV rays when compared to ABS. Plus, their flexibility ensures you receive exceptional print quality. Dive in to explore the myriad of ASA filament options waiting for you.


Here’s a rundown of the top five ASA filaments for 3D printing:
– Polymaker ASA Filament
– Flashforge ASA Filament
– SUNLU ASA Filament

Let’s unpack these choices:

1. Polymaker ASA Filament
Polymaker ASA is the filament to opt for when crafting items that will be exposed to persistent sunshine. It’s fantastic for projects that require a sleek matte finish. For optimal mechanical properties, consider turning off your fan, or keep it at 30% for enhanced print precision. A seasoned user who’s worked with over 20kg of this filament lauds its cost-effectiveness and superior quality. A different enthusiast noted a minor hiccup with the cardboard spool, but many applaud its consistent performance and adhesion capabilities. For those utilizing a flex plate, a swipe of Elmer’s glue stick might enhance bed adhesion. Remember to preheat and maintain optimal temperatures for best results.

2. Flashforge ASA Filament
Flashforge, being a renowned name in the 3D printing world, naturally garners attention. Their ASA filament can endure temperatures up to 93°C without warping. Unlike ABS, it doesn’t contract and is thoroughly dried before sealing. Some users tweaked the print settings, like increasing temperatures, to achieve the best outcomes. Many highlight its clean prints, surpassing even some PLA filaments.

3. SUNLU ASA Filament
The SUNLU brand stands out for its sturdiness and user-friendliness – a boon for ASA novices. It excels in layer adhesion and is impervious to water and sun damage. Some users, after a bit of trial and error, found that adjusting fan settings and bed temperatures optimized their prints. Most newcomers appreciate both the packaging and filament quality. Pro tips? Adjust your printer’s temperature settings and try out a glue stick for layer adhesion if facing challenges.

4. OVERTURE ASA Filament
OVERTURE’s filament is meticulously inspected to guarantee effortless feeding to your 3D printer. Its resilience and resistance to the elements are commendable. Post-printing, placing it back in its original nylon bag can preserve its quality. Users who transitioned from ABS to OVERTURE ASA have had splendid outcomes, with many choosing to remain loyal to this brand.

5. 3DXTECH 3DXMax ASA Filament
If you’re into technical parts, 3DXTECH 3DXMax is your go-to. Especially when a glossy finish isn’t the end goal. It’s well-suited for components exposed to temperatures as high as 105°C. Some users faced challenges in achieving consistent layers but found their groove with tweaks in speed and temperature. The filament’s finishing is often praised, with layer lines nearly invisible at 0.28mm. It might require an enclosure for optimal results, but its exceptional prints make it worth the effort.
