ASA Filament 1.75mm, UV/Heat Resistant/Weather Resistant ASA 3D Printer Filament, Perfect for Printing Outdoor Functional Parts, Army Green Filament 1kg(2.2lbs) Spool

Filament reviews for anything more finicky than PLA are hard because most bad reviews reflect the any number of variables that can affect printing a new filament. I've printed a lot of ASA and I've printed with 6 different Isanghu spools of it. My customized profile would occasionally run into problems with it vs the Overture it was created on and using lightly modified standard profiles on my K2 Plus for ASA have had great results. I was floored to find colorful hombre filament and love the purple. The gradient is awesome. The quality is on par with any of the other major brands. I had no clogging or issues when switching between colors, no feed problems with the CFS that I often encounter with Polymaker (random out of spec stretches on the reel). I dried for 8hrs as I normally do and had no problems, no lengthy dry time to get printing. The reel was very consistent with printing. I wasn't expecting the ease of use for a price 30% less than others but it's become my "everyday" ASA. Really an affordable ASA that doesn't come with a lot of string(ing) attached.

I had zero issues printing with this filament. Adhesion (bed and between layers) was great, no warping, and the filament flowed smoothly and evenly. There are some surface defects on the corner piece but I get those when I print with Polymaker ASA too. That part is printed on an edge (as shown in my third picture) so there can be a little wobble towards the top of the print. It’s overhangs all the way up and the filament printed perfectly. I printed on a Bambu Lab X1C which itself is in a filtered enclosure to deal with VOCs (which is how all ASA filament should be printed indoors). I used a smooth PEI sheet coated with liquid glue. Bed temperature was 100°C and nozzle temperature was 270°C. I added a brim when I printed the corner piece; the bird feeder didn’t need one. I always calibrate filament before printing with it for the first time. ASA isn’t hard to print with but you must have the right setup and knowledge. The negative reviews seem to be from people who lack one or both of those things. I would definitely buy more of iSANGHU’s ASA, especially if they introduce more color gradient ASA!

This is a very matte filament with a nice surface finish. Prints easily on my Bambu H2D

I ordered a roll of this, would not work. Wouldn’t not stick to my plate no matter what I did. I got a replacement and it’s the exact same way

This iSANGHU ASA filament has been excellent so far. Once dialed in through BambuLab Studio, it prints smoothly and reliably. I used it on a BambuLab A1 with AMS Lite in an enclosure, on a textured PEI plate with glue, and every print has come out great post-calibration. It’s UV, heat, and weather resistant, just as advertised. Quality is solid, with consistent extrusion and no clogs. The price is also very reasonable — especially compared to official BambuLab or even some PLA options. Highly recommend for ASA users looking for performance without overpaying.

Great print quality, strong solid parts. The only downside is the white color is more “natural” than “white”.

I've used polymaker and overture ASA to make parts for my business for a good while, but decided to try something different out of curiosity. When this filament arrived and I saw the spelling error on the box I thought it was going straight in the trash. But I printed a bunch of parts with it and they came out better than polymaker! The top surface is like glass, which I've never achieved with anything else. The parts are just as strong as the others. I print with a K1 Max. 100 degree bed and 275 degree nozzle at 200-300mm/s. The people with layer adhesion issues are probably not printing hot enough. Warping issues are likely poor first layers or no enclosure. And the guy who said it's not like any PLA he's used.. well.. that's obviously user failure. ASA takes some dialing in, but when you do it's great. And the isanghu ASA is surprisingly amazing!

I purchased the ASA Orange Filament and it was my first time using ASA. I wasn't disappointed. I found that it printed as easily as PETG once I got the settings dialed in for ASA. I'm using this inside of my Sunlu S4 dryer and I tested it at 70c for 5 hours. There wasn't any distortion at all. The orange is vibrant and so far it has maintained its color. One thing that really impressed me is the dimensional accuracy is nearly perfect. I will definitely be ordering more of the ASA and highly recommend it.

As described. Fast delivery!

Seems like good filament once you get past the challenges. I have the orange coloured one and the pictures make it look like a much deeper orange. The reality is a much lighter orange.

I needed to make a 'LEG' for my AC bracket outside. The only concern was finding a material that would withstand the hot temperatures when the sun is beating down on it. PLA bends and deforms easily under a little heat; PETG can withstand a bit more but cannot hold up in the long run during the summer temperatures, especially when the weight of the AC is acting on it as well. This is when i turned to the option of ASA. I was very surprised to see that you can buy ASA for cheaper than some PETG and PLA in the market. I printed this leg in a bambulab p1s, there fore i was able to maintain the heat in the chamber during the process without any warping issues. I read online that people had trouble with ASA when they print it on bed slingers. Therefore i highly recommend that you print ASA in an enclosed printer. The leg has been installed on the AC bracket from May till as of now (October) and has survived even the worst heat waves this year without deforming even a tad bit. I am very satisfied with this material and would buy more for future outdoor applications over PETG.

Extremely happy with this ASA. Color reproduction is great. No problems with layer separation or delamination. I have made several products for outdoor use and they are still standing after a year. I have tried a couple other brands on Amazon and was not impressed. They had delamination issues and the color was off.

Really solid filament, prints well and the price can’t be beat. Using a Bambu p1s, cranked the settings. I am using a flowtech cht nozzle though which helps
