ASA Filament 1.75mm Red, 1kg ASA 3D Printing Filament, Heat & Weather Resistant - ASA 3D Printer Filament Perfect for Printing Outdoor Functional Parts

This ASA filament has been an absolute standout performer on my Elegoo Centauri Carbon. From the very first print, I was impressed by how effortlessly it handled a material that’s often considered challenging. I’m currently printing a full-scale tank using a 100°C bed and a 270°C nozzle, pushing the machine at incredibly fast speeds—and the results are flawless. Where most ASA recommendations emphasize slow printing to avoid issues, this setup completely defies expectations. The layer adhesion is excellent, surface finish is clean, and there’s no warping or defects in sight. If you’re looking for an ASA that delivers both speed and quality without compromise, this is it. Combined with the Centauri Carbon, it’s a powerhouse pairing that produces consistently professional results. Highly recommended for anyone who wants reliability and performance at the next level.

I picked up this Polymaker ASA in orange to start printing some functional outdoor parts, and it hasn’t disappointed. The color is vibrant, the spool was neatly wound, and it fed smoothly right out of the box. Print quality is excellent—layer adhesion is solid, surface finish is clean, and it handles bridging and overhangs better than I expected for ASA. I’m running it in an enclosed printer, and once dialed in, it’s been very consistent. Slight warping on the first print, but after tweaking bed temps and using a brim, no further issues. What really stands out is the durability. This filament is tough and UV/weather resistant, which makes it perfect for brackets, mounts, or anything you need to survive outdoors. I’ve printed parts for my patio setup and a few car accessories, and they’ve been holding up great in sun and heat. If you’re looking for something tougher than PLA and more outdoor-friendly than PETG, this ASA is a solid choice. Highly recommend for functional prints.

Reliable ASA for outdoor prints or high heat tolerances.Im using it outdoors and also in a AMA while drying PETG at 70°C. Has a predictable shrink around 2%. Color look, quality and intensity is great with this brand too.

First and foremost, this was my first time ever printing in ASA. Initially, I started with ABS but could not stand the smell. Even with my air purifier on high, it was horrible. Out of the box it had alot of moisture that made it unbearable to print with so tbh, im never touching the stuff. Looking for alternatives, Polymaker came up and decided to check them out for the first time. I'd only ever printed PLA but mostly PETG. This project required either ABS or ASA for thier properties. If you've never printed with either of these, its not for the faint of heart. I liked Polymaker alot better as the smell wasn't so nauseating. Subtle with no enclosure and barely noticable with. I always run an air purifier that can filter any offgassing. I plan to print a nevermore filter also. It was a challenge for me to get this dialed in but in the end, this is what worked: - The bed really needs to be properly leveled, I cannot stress this enough. - I have a flex plate with a piece of probably 1mm pei on it. I sanded it to get it scuffed up with 80 grit sand paper (didn't have textured pei so this was the alternative). Washed it with dish soap, dried it and wiped it down with iso alcohol 90%. - Enabled Linear Advance and used teaching tech's video to configure (easy). This is optional but I've been hearing about it and found that it truly does improve the quality of the print. - Ensured that Z/ESteps were configured (I had to change extruders). The calibration cubes all measured the correct size. - Adjusted the flow rate. This really needs to be checked to avoid over extrusion even if the steps are correct. - Use elmers glue stick (the xtreme version). Believe me, I experienced warping when first attempting to print this. Initially, tried ASA juice/slurry which I advise against because it reeks and is a PITA to clean. Also tried sugar water which is laughable but seems to work for some. Get the glue stick. It's cheaper, water soluble, non-toxic and it just works. Not spending $20+ for the competition. Just run your flex plate under water and boom. If using on a bed take something to wipe it off (safely) if needed. Done cleaning. - Consistent heat. Do a PID tune. I found that this was one of the main reasons for warping. Whether using your printer in an enclosure or wherever, make sure there are no windy drafts of air. Also, I was used to setting certain temperatures for the first layer then reducing it when printing PETG. Not this time. Leave it be. - I stopped using brims. They work to reduce warping/corner lift but I can't stand them. Even though this ASA is relatively easy to sand, its annoying to remove/post-process especially when you have alot of small parts. Settings/Printer: Tevo Tornado Prusa Slicer 250 Nozzle Bed is preheated for 10m (heat soak) 90 bed (truly dont need to go higher than this) 2 skirt lines Draft protection (hey it works but is probably not needed) I highly recommend this brand. Once you get things dialed in, it prints like butter. No moisture issues as the filament is well vaccum sealed and I keep all of my filament in an airtight container with dessicant at rest and in use. Love the natural color.

Printa great, but needs a few things to print... Make sure you have ventilation because it smokes a bit during printing. You also need a very clean bed with glue added. I had one failed print due to not adding more glue and cleaning between prints. So, make sure you use lots of glue. Follow up after finishing the spool. I had two failed prints due to bed adhesion. This stuff does not like to stick to the bed, and is prone to warping. I had to heat and fix two parts in post process. Deducted 1 star to 4/5

Polymaker is my go to for ASA. Unless I have a need for a specific color or shade they don’t offer, this is the stuff. It prints just as well if not better than any PLA (with appropriate settings and enclosed of course). I’ve printed at pretty high speeds (350mm/sec) and flow rates and never had an issue. Spool winding has never been a problem, nor has moisture content. Parts pop off the bed as it cools. Honestly if they offered more color shades and various special colors like Burnt Titanium or dual/tri-color, I would have no need to use anything else. I do like the galaxy line and have no see galaxy blue on some custom printer parts. The Jet Black is very black. Love it all ❤️

I got this to help me rebuild my custom CoreXY printer and replace a bunch of PLA parts with a more stable plastic. This stuff has done an amazing job and was a lot easier to print with than from what I read on other reviews. I started with a glass surface and the glue stick trick which worked and later upgraded the printer to a good spring steel printer plate. Both surfaces so far have turned out some amazing prints. It is highly recommended to have an enclosed print bed so you can maintain the ambient temperature but since I still have an open frame and haven't figured out how to make an enclosure I went ahead and used it without and found it still worked and turned out some great parts.

My first attempt at printing anything other than PLA. There was a bit of a learning curve, but it worked great. Babysit it for a couple of small prints and it should be pretty easy to dial in. Bed adhesion seems to work well with a textured PEI plate, 110 degrees, with a brim. It will pop itself off if you allow the bed to cool to room temperature. I haven't tried any large prints and I'm not sure how much I would trust the bed adhesion without glue for something large. Parts seem very durable. Color is a fairly close match to Magpul FDE. Printed at 255 degrees on a Flashforge Adventurer 5m. No fan for first 3 layers, 15% fan for the next 20 or so, 50%-100% fan for the rest. Printer is in a Creality zip-up enclosure, feeding filament from a Creality Drybox 2.0. I use the Drybox as more of a spool holder than anything else, so it wasn't on for the first 12 hours or so of the filament being out of the package. I printed several times successfully, but then it started to have some significant stringing, so I turned the Drybox on to 60 degrees. Stringing decreased after the Drybox ran for a while. So it seems like this stuff needs to be kept pretty dry. That or I messed up that one print and it was just a coincidence. Idk. (Edit: turns out my retraction setting was too low, so the stringing was most likely user error) For what it's worth, I was printing it at 300mm/s, which is way faster than it advertises, and I managed to get pretty decent parts with no clogging. But I was also printing relatively small parts that were designed to be easily printable. Your mileage may vary. I'm quite happy with this filament and would order it again.
