Polymaker ASA Filament Bundle 1.75mm, 2x1kg Heat Resistant Weather Resistant ASA 1.75 Cardboard Spool - PolyLite ASA 3D Printer Filament Black 2 Rolls Bundle, Perfect for Printing Outdoor Parts

Pour moi qui roule une imprimante avec enceinte chauffée et filtre à air (Voron modifiée), je ne touche presque plus au PLA ni à l'ABS et utilise quasi-exclusivement de l'ASA pour mes projets. Et ce filament est de bonne qualité à un bon prix. Je n'ai pas été déçu.

I’ve been using this ASA for the past couple years for 3D printed products. In the beginning I had no issues and made it my go to ASA. Sadly though about a year ago I noticed a serious print quality issue that has become more and more common per each roll of filament I purchase. The issue is that for what ever reason that is not due to moisture (I dry my filament with eibos dryer) the printed product will have pin holes all over the exterior of the print (not using random seam either) making my product disqualified for sale in my books costing me time and money. At first this issue would happen once every 5-8 rolls I’d buy so I’d simply exchange it for another. Currently it’s about every other roll I purchased exhibits this issue causing me much wasted time. I’ve personally hit my limit with hoping this was a temporary issue and am currently shopping for another ASA brand to replace it with.

This is my go-to ASA filament. It prints easily (typically use 240C head 100C bed), and finishes with a nice mat look. I do have some stringing, especially if the filament is not dried regularly. However it is pretty forgiving and not much more difficult to work with than PLA. It's a great option when you need something that can survive the temperatures inside a car during summer time.
