What is the best ASA filament? 10 different ASA brands tested

[@ScytheNoire]

Whatever FormFutura is selling, it's not ASA. They might not have wanted to send filament to you because you exposed that their ASA is extremely impure and doesn't behave like ASA. Really appreciate these tests.

[@1Kingcb]

gotta be a petg mix like an abs +

[@matschase]

@@ScytheNoire I really enjoyed printing FormFutura for my Voron parts. Whenever I had warping issues, this was my solution. Interesting to see that the mixture also has its downsides. Pretty logical, but I would have never expected such a big difference. However, for my Voron it's working absolutely fine with no issues

[@zapl80]

They advertise it as a modified ASA with less warping. Changing material properties always has side effects but that doesn't make the stuff bad. And ASA is already a compound, so even Filament made only from A,S and A can be different to each other

[@ArgueForSport]

Thanks, Igor. I print a lot of ASA, and this is really helpful! Mostly QIDI and Polymaker / Overture, so it was good to see the differences.

[@MyTechFun]

Overture was too expensive to ship from US to EU (I bought Overture PETG, I couldn't find it in Europe)

[@ArgueForSport]

@@MyTechFun In my opinion, no need to test Overture. It's identical to Polymaker. Import records (public info) show they come from the same factory in Suzhou, and I've run them side by side. The orange and purple for both is identical in color as are the spools. There are some who believe Overture is a sub-brand owned by Polymaker. I just know they have some filament coming from the same factory. There are other brands that also do the same. Flashforge makes for Voxel. Kexcelled owns / makes Hatchbox, which is their US brand (it's on their website, too). Kexcelled also produce a number of filaments for QIDI and others.

[@masf72]

@@MyTechFun Overture and Polymaker are the same filaments, Overture is a sub-brand of Polymaker.

[@GiulioJiang]

Thanks for including warping test. It's a huge decision factor for all the people that don't have an enclosed printer!

[@garagecedric]

Massively time consuming test, well done. I use ASA for less stressed car parts, though i hate the smell, even if I have the printer in the garage. Maybe you should buy a serious air cleaner with so much printing indoors, for the sake of the family:)

[@MyTechFun]

Thank you, I am glad that you find the video useful!

[@ixe87]

What material do you prefer for more stressed car parts?

[@garagecedric]

@@ixe87 I use prusa PCCF for most parts since its not affect by moisture, is stiff and doesnt creep like nylon, can handle 130C . Also added add North PC Which should handle 185C, but havent done any car parts with it yet, but i have plans :)

[@MyTechFun]

@@ixe87 depend of the stress type. Against bending pc-cf. But I like ASA too.

[@naminiyo1]

@@garagecedric polycarbonate absorbs less moisture, but still its properties vary with moisture as PA does, a better alternative to PAs are PPAs( polyphtalamides or semiaromatic polyamides, but yes, they're also more expensive). polysulfone has a glass transition of 185C, yes it's more expensive than PC, but CF is an abrasive material that may reduce the life of the nozzle.the best in my opinion,although not feasiblefor economic reason would be polyertherimide (PEI), with a glass transition of 210-215C.glass transition ( temperature where the polymer starts to soften) it's not the only parameter influential to creep but plays a lot into it. Just adding a bit of info that's all :)

[@DieterHenkel]

Thank you very much for this very good test! I prefer ASA over ABS, even though it is more expensive. Your test gives me a well documented guide line which filament to buy.

Thank you, and more similar comming soon (10 transparend petg, 8 black ABS..)

[@TomRechlicz]

Regarding the exhaust fan. Using a 4" diameter dryer vent hose alone was not enough to vent the printer which is a Bambu Lab P1S. I used a 120mm 12v computer fan which I had on hand at the end of the hose at the window end and that sufficed to vent the printer with no odor in the room. Thanks for all your work, I have found it incredibly useful.

[@TetraluxOnPC]

What diameter of tube did you use?

[@naasking]

Great analysis, thanks! I primarily use eSun eASA so I'm happy that it was a solid contender on most metrics. I was planning on trying it for some drone frames, and it looks like a solid choice given its impact performance. I'm impressed with FlashForge's ASA too. Not great on impact performance, but it's very stiff and has very little creep, so it would be a good choice for structural parts in a 3D printer.

[@scotsanders1156]

I am so thoroughly impressed by your testing. Just an amazing amount of effort. Thank you so much. I will be returning to watch other videos just to see the tests!

[@nihiltube]

Thanks for the great video!

[@MyTechFun]

Glad you liked it! Thank you for the support!

[@Interspieder]

Thanks for the video! To filter the vapours from the filament, I installed the Bentobox system (with 2 radial fan mod), which circulates the air and filters it through HEPA and activated carbon. Advantage: The air temperature remains constant, no cold air is drawn in. However, for the system to work properly, the enclosure must be reasonably airtight.

[@kainkamote917]

This video came in the perfect time. I've been doing a lot of research on what filament to use inside a car for paneling. I've been leaning towards ASA and your comparisons are exactly what I need.

[@vientosnomadas655]

have you looked into protopasta's HTPLA and CFHTPLA?

[@rallyfeind]

I have worked in a plastics plant and all the interior panels we made were PolyPropylene. There were 2 grades and the tougher was translucent and the lesser was opaque when we purged the natural material. The stuff for under the car was a conditioner added abs and normally a regrind of any scrapped PP parts.

[@madengineer9072]

This is very useful information and I really like how well everything is laid out and documented. I will definitely pick up some 3DO filament and try it out. I've been printing with ELEGOO ASA quite a bit, which has had no warping, but haven't really done a head-to-head comparison with other ASA filaments.

[@SanguineVoyeur]

I def appreciate this one. I rarely use ASA, so when I do need it, I don't really have the time or space to test out a bunch of different brands to find the right one

[@RobertoMello79]

Thank you so much for making this video, I print most ASA and ASA+CF, your video helped me clear some questions I had. You didn't test the main brand I use, but if I go by the average, that helps. Thank you so much

Exactly the topic I needed! I print a lot in ASA and this video was very helpful. Thanks!

[@oden7269]

Thanks, Igor. A very useful video! I am slowly emptying my ABS stash and moving over to ASA, mostly 3DO, so I am very pleased with the results, too.

[@eltorro]

I just recently started printing ASA on rare occasions. The spool of Elegoo I've been using has been printing well so far. These results will definitely influence my next ASA purchases.

Your test discipline meets my expectations for quality of objective analysis results and your array of test parameters / results is quite impressive. As you conclude, the ultimate selection should be for the performance characteristics that are most important, and in this regard, we have made the same brand conclusion (I have observed about half of the products you tested, plus PA CF filament - disappointing).

[@Maschine_Fuhrer]

why asa and not others ? there are better and easier to print filaments in my opinion

[@Shamano37]

This is great testing! I was looking for the best filament to last outside in the heat, ASA was obvious, but this helped me picked which brand to use. Can't get 3DO in the US, so I will be trying FlashForge.

[@MyTechFun]

Glad it helped! I think they have a reseller in US. Try to ask 3DO about it. (you can mention the video too ;-) )

[@ixe87]

Great Video! Thank you! ASA is a great material. I only print it if I really need it, for example for internal parts for my Prusa XL 5T with enclosure. I only have a spool from AzureFilm, the normal black ASA (not Prime). Its OK, but it warps more than your tested AzureFilm ASA Prime. I wish I could send you some printed samples of my ASA, so you can test it an add the values to your database. Could you share your STLs and print values? But it would not be representative, because of different printer etc. Maybe i should send you some Meters from my ASA ^^

[@MyTechFun]

Test objects are here: www.printables.com/model/465670-mytechfun-test-objects and almost every test object is printed with max number of walls. The vertical (for layer adhesion) is missing there, I will add it when I finish replying to comments..

Just a comment to help with the algorithm. Thanks for the video. Great selection of brands!!!

[@MyTechFun]

Thanks for that!

[@cameronlea7633]

Thank you for this testing Igor. I think the big barrier for large prints is the warping/shrinkage with ASA. I have only used Polymaker ASA at this point and can relate that it definitely warps. Would you be interested in doing a spinoff video on printing the Azurefilm and Formfutura with larger prints (maybe p1p bed size) for a true anti warping champion. Also, could add something to increase adhesion on some of the others that had low warping but other good performance metrics. Thanks again!

[@contrezerva9024]

Polymaker ASA I think is a good brand/product, but in my case, warping and shrinkage did not have a happy end in my case. I still have to tweak stuff

[@tinkeringpoko]

Oh I print quite a bit ASA. A recent experience was with elegoo (can't resist to try 22USD\2kg). They print okay but warps in my K1's 45 degree C chamber... Wouldn't mind printing a lot of ABS ad well, especially when I don't need UV resistance. I print those in my garage and have a blower fan ventilate the place afterwards so the odor doesn't really bother me.

[@TarianJEDTech]

I have a similar exhaust setup for my X1C. I have the TerraBloom ECMF-100 setup as my inline fan. It is designed so you could hook up a Arduino or similar to control the fan speed.

I use 3DO ASA for most things. Prints perfect on a K1 with MS FlowTech hotend. NO warping if you keep chamber at 55-60C, just throw a blanket over and block venting if needed. I limit to 20mm3/s, 150mm/s at 245C and it always works . . . Your experience may differ

[@LifeOfBrian83]

For the next test you should use the same color for all filaments or test natural filament as the color pigments affect the properties of the filament. But still a nice and valuable test! Thank you.

I use only the chamber fan and only at 40% just to create slight negative pressure rather than actually trying to suck too much air out (it needs to get in somewhere to replace it). With a Bentobox as well, I get no smell at all in my small office space.

[@woutervossebeld4664]

Thanks for the indepth testing, I would suggest that next time you use the same color for all brands as the pigment has quite some impact on the material properties

[@mjodr]

10:26 You are pointing out that you have AC to keep the temperature constant, but that is not my concern since I have been using ASA the last few years. It is the airflow that will warp it immediately. I don't print with an enclosure, but I make sure all my fans are off, my window is closed and I do not walk up to the printer too fast or close the door to the room. Any of that will warp it instantly. I'm afraid that with an AC unit creating airflow right next to it will throw off the results greatly.

[@MyTechFun]

I think you have to watch the video again. There the point was not to have perfect conditions, but perfect constant warping conditions, to see some difference between the filaments. And it worked really good, we can see big difference between them. In perfect conditions, all of them was printed fine (test objects on X1C).

[@mjodr]

@@MyTechFun Ah, ok. Must have been the phrasing or accent. I wasn't following what was being said I just saw the AC unit and went "That is 100% warping conditions" and then heard "The temperature will be very stable" and thought "that has little to do with warping". I didn't realize the point was to induce warping.

Hi, I’ve just noticed that Bambu has a fillament I can’t find any reviews for (myst be new): PPA-CF. They also say it’s easy to print. And that it has “metal like strength”, high precision, great humidity resistance and high temp resistance. But no videos on youtube. It’s 100+ Euros for 0.75kg. It would be very interesting to see all your different kinds of tests on it (strength, layer adhesion etc.). Including heat set inserts tests. Would they maybe send you one? 😁

[@Ojref1]

You know, another good test for ASA in the future might be rapid sun weathering - exposing it to UVA and some UVB frequencies (using UV lamps) for a bit then testing surface hardness and strength. After all, ASA is supposedly formulated to resist that kind of light damage, and a primary driver to select it over ABS for outdoor applications. Cheers!

[@CreationDominion]

Double check this info. X1C intakes, P1S exhausts out of that vent. At least, logicalplanet states that their venting designs won't work with X1C because flow is reversed... I only have a P1S and the exhaust blow air out of that vent.

[@uhu4677]

Can you check into why the ApolloX performed so poorly in the creep test and the impact test? With that kind of creep performance, it would be rather useless for outdoor purposes.

According to other comments, this is highly modified ASA. The printability is great, but they sacrifice some other mechanical properties. But I don't have details what are the main components (beside ASA).

Turns out of the 10 ASA filaments you tested the 3DO ASA is also UL94 HB 1,5 mm rated. Thanks for making me aware of this alternative I could use. I wish there was an UL94 V-0 rated filament. Currently I have to choose ABS for that, which has less UV resistance. I don't think there is any technical reason why they couldn't make ASA with that rating.
