FLASHFORGE ASA Filament 1.75mm Black, 3D Printer Filament 1kg (2.2lbs) Spool, Dimensional Accuracy +/- 0.02mm, Durable, High UV-Resistant, Perfect for Printing Outdoor Functional Parts

This has become one of my regular ASA filaments for functional prints. I have moved away from PLA and PETG entirely at this point. Swapping filaments between projects is more hassle than it is worth, and the non-engineering filaments tend to get brittle and unreliable after just a few months sitting on the shelf. ASA holds up over time and prints I made months ago still look and perform like the day they came off the bed. Dimensional accuracy on this filament has been consistent. The advertised tolerance feels accurate based on the parts I have printed, and dimensions come out true to the model without needing to compensate in the slicer. The spool itself is wound cleanly with no tangles or weird behavior during long prints. Print quality has been solid across a range of settings. Layer adhesion is strong, the surface finish is clean, and the black color is a true black rather than a washed out gray. UV resistance is the main reason to reach for ASA in the first place, and parts I have placed outdoors have held up well without the yellowing or surface degradation you get with cheaper outdoor filaments. One important note for anyone new to ASA. Ventilation is not optional. The fumes during printing are noticeably stronger than PLA or PETG, and you should always print in a well ventilated space or with a proper enclosure that vents outside. Take care of yourself and set up your workspace properly before diving in. For anyone printing functional or outdoor parts, this is a reliable choice that has earned a spot in my regular rotation. Good filament at a fair price.

I'm fairly new to 3D printing but I did my research and found that this brand was considered middle of the road for quality and price. All my prints have come out well using this brand and I have no complaints. The flow and flexibility are great. The companies transparency of the specs right on the side of each spool is a nice touch I thought.

Picked it up on a whim on sale, needing to do some outdoor ready prints. It took me a little to get it dialed in, but it was printing pretty well out of the box with default Bambu Labs ASA settings. I eventually calibrated it an enjoy a 29mm^3/s max flow rate in my stock 0.4 nozzle which allows for some blazing print speeds. It became my default ABS/ASA choice and I've gone through several rolls. It off-gasses like other ASA, so have ventilation and/or carbon filters. It also can warp, but not quite as much as ABS. I find high aspect ratio parts, or parts with curved, filleted, or relieved edges can benefit from brims, although most parts can get by with simple mouse ears at corners which take less post processing. It works well with salt remelting (the surface finish will be much different than stock, very matte and much lighter) and acetone smoothing.

I have ordered alot a filament through flashforge and have always had great quality results. This time something was different, the filament (burnt titanium asa) looked fine out of the box but was wound very poorly and kept getting tangled, causing failed print after failed print, once I got that taken care of and was able to get a full print I was very upset with the quality of the print it was very coarse not smooth as usual and the layer adhesion is almost non existent and parts break in half just removing them from the print bed. This filament failed soo often and jammed up my extruder so badly that I will not buy asa or possibly any more filament from flashforge for fear that I will be wasting alot more time and money fixing what this stuff does to my printer.

I print a LOT of functional parts that are used outdoors. I really like the Iron Grey color and have had great success printing this on a Bambu H2D printer. The FlashForge ASA filament is the best overall value I've found for functional parts.

Update: After a lot of tweaking and building myself an enclosure with heated bulbs to get it at stavle 60+ temps , i managed to print what by all intents and puposes shouldnt have printed on a bed slinger (BL A1) , see last photo , superb but as i said , layer adhesion is t the greatest and you absolutely need a heated enclosure for anything higher than a few inches...use of rafts recommended I really have nothing bad to say about flashforge themselves , as ove used a lot of their filament , and this is the first one im utterly disappointed in, maybe i got a bad roll but im half a roll into it , and nearly 20 test cubes and prints , ive even built myself an enclosure and it doesnt really help ..first off if i try to print this at 240 i get bubbling , at best i can force 90% cooling and it mostly works but i can tell it doesnt like it being that hot , yet at 235 i get delamination( poor layer adhesion) so bad that i can literally snap part in half and then peel off a layer at a time Ive tried everything with this ASA burnt titanium but unless it really absolutely needs a +50 degree enclosed space ...i literally cant print anything of use on this thats not decorative at best , i get a perfect looking benchy or test cube...that i can literally crush... Test cubes from left to right show different temps, left most being 235 and it printed pretty good , but on bigger parts all i get is brittlenes similar to printing with matte pla , im positive its dry as you can see it prints with a great finish at right temp....just cant get thing to stick to itself....

I found this to be a great filament in my ancient 3D printer. I formerly used a considerable amount of ABS and PLA, but this was my first use of ASA, and I was very happy. It came well sealed from the factory and I did not have any problems with how it fed. I was also pleased with the look of the final product, but to be fair, my printer is very old and imprecise, so I can't judge that aspect as well as some other people might using newer and better printers that showcase a great amount of detail. I was just happy for this stuff to make a complete and sturdy print that held up to outdoor exposure in the way that I required.

TL;DR: Great print quality, slow first layer, printed a whole Voron 2.4 350mm with this stuff cuz its that good. Hot End: 250c Bed:110c Speed: 60mm/s First Layer: 10mm/s Found this ASA on sale and was a little be suspect, but flashforge is a well known 3D printer company. And I've had great success with Voxelab (owned by Flashforge) filaments in the past. First few prints weren't so good, I was using my proven ABS settings and was getting ZERO first layer adhesion. So I tried to slow down the first layer speed to IMO a ridiculously slow speed, and crank up the bed temp from 80c to 100c. And BOOM it stuck great to my PEX sheet. Layer adhesion after that was perfect! The shiny finish is nice to. Makes the Voron I printed out of this stuff shine. This filament like to be printed hotter than other ASAs I've used in the past.

This is FANTASTIC! I thought i had found the best filament ever when I bought Polycarbonate but this is even better! This is slightly stronger but slightly less impact resistant than ABS. Slightly weaker than Polycarbonate but Polycarbonate doesnt have much impact resistance if anything at all. I've printed various RC car parts with this and every single one has come out perfectly, its pretty much the God filament for me. Im yet to test the strength of a spur gear but I have printed 4 of them with this filament and the finish and strength are seriously impressive. As soon as I get paid I'm buying a few more rolls of this, from now on I'm printing EVERYTHING in Flashforge ASA!

Print goed en ziet er uitstekend uit. Uit de verpakking gehaald en gedroogd in Polydryer voordat ik het heb gebruikt. Ik heb een Bambu P1S. Instelling: Generic ASA. Shrinkage gemeten: X-as 99.44% en Y-as 99.56%. Gemiddelde shrinkage 99.50%.

Plastique très facile à imprimer du moment qu on l'a bonne imprimante une buse qui chauffe bien et un plateau aussi. Il n' y a pas d'odeur. J ai fait un abreuvoir pour oiseaux et avec l' asa il est bien étanche et en plus ce plastique résiste au UV.
