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

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.

This stuff prints absolutely beautifully and effortlessly. You can go fast with it, if you take the time to preheat the chamber and use an adhesion promoter like Hyperlok on the bed, it's (for me at least on my Bambu X1C) simple. Solid profiles in the slicer by default, prints are gorgeous. I'm now ~1.25 kilos in on this stuff printing an AMS riser/drawer thing. Looks great, feels great, highly durable too. Yes, it's a bit on the pricey side, but you won't regret it. Yes, it's a premium product, but it delivers premium results too.

Prints fantastically on my Bambu p1s using generic ams profile. Printed so far using .2mm layer and it has been great. I allow about ten minutes of full 100 degree bed heating to heat soak the chamber before starting and have had zero lifting, warping, etc. The color is bright and vibrant and looks great. No clogging issues thus far and have used about 2/3 of the roll thus far of the green and about 2/3 of the black as well.

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.

Good filament and a good price. Cardboard spool and neatly wound is also a plus. I do notice that this material will off gas significantly and has stained the inside white walls in the Prusa HT90. It does not clean off of the white surface. I would definitely use this only in an enclosed and air filtered setup to avoid exposure to off gas particulate.
