Great review! We print from PA at work - various holders that need to survive the 125 C heat chamber test of our products. It is an amazing material. Two remarks from my experience: PA6 and PA12 (and i think also PA11 exists) are both nylons, but mechanical properties are noticeably different. And second remark is actually an advice - if You dont want to spend money for special PA print sheet for You printer - either use a lot of stick glue, or print a layer of 0.2mm PETG and then print the PA part on this. It really works!
Amazing review as always, this channel needs 100x more view, I will be sure to promote it whenever i can I will also be joining the patreon soon! I was hopping you would cover the PAHT-CF too, hopefully you will cover that one on the next video with the PPA-CF or in the near future? The PPS-CF does not seem very interesting from the spec sheet but I will be interested to see the results.
Your video makes me want to run out and buy the PA6-CF, but I realistically don't have any practical use for it currently. I know I will be looking for models to print with that filament from now on though.😁 Thank you for your awesome videos and your dedication to the facts and testing as an engineer.
That's really interesting, with this PA6-CF filament, the biggest disadvantage of nylon is gone ! Once I have a printer capable of printing nylon, I will give this one a try. Amazing video as Always Igor!
I really enjoyed this video. I've been liking the whole series but seeing you start to get into some higher temp filaments is exciting. If you're taking suggestions I would love to see a few more tested in the future. 1. 3dxTech EZPC-CF. I love this filament and it's my goto high temp filament, but it is expensive. 2. West3d Ambrosia PET-CF, (not PETG-CF). Supposedly a much more affordable competitor to EZPC-CF but it needs annealing. 3. TreePD PC-PBT-GF. I keep seeing europeans who swear by this stuff but it currently isn't available in the us so I can't test it myself. I have heard properties are better than EZPC-CF. If you do test any of these seriously consider drying them first. They all need a few hours at 90C to dry and I don't think many people using filaments of this grade and expense are just printing them like pla without drying them first.
Regarding the layer adhesion values. A lot is depending on the temperature, layer width, chamber temperature. See CNC kitchen video about heated chambers. I made no direct testing, but the PACF parts I have tested printed at 65C chamber temp fail quite nice, fracture does not really follow layer lines. Egyébként szép munka, köszönjük!:)
Wow that temperature resistance is great! Awesome shear strength too. Very disappointing layer adhesion on the GF version is a bummer. Will have to design parts accordingly.
Great video as always! Will you be testing the Polymaker PET-CF17? It appears that once the Nylon part is “wet” after printing that the PET becomes stronger, just less heat resistant. I’d be interested in hearing your opinion.
I like your tests a lot but miss only that you add the standard filament without GF or CF in the test. It would be interesting how the standard PA6 (or PETG, PLA. ASA, ....) compares to the GF and CF variants as well because it would help to choose the right filament.
Wow, what fascinating materials! Can we conclude that these are among the toughest (or THE toughest?) filaments while maintaining printing conditions that many consumers can handle?
Nice Job! Would be interesting to boil the materials in water for the same time and see if it also affects the strength without loosing moisture. Maybe one at full power and one at middle heated cooking plate.
From what i heard, in manufacturing, batches of PA parts are bagged with an appropriate amount of water and allowed to absorb for 24-48h in this very moist atmosphere, so they reach 4% moisture absorption rapidly. Then over the years in use some moisture can be lost depending on circumstances, but overall as you might guess it's fairly good at holding onto moisture. I wonder how much moisture they gain when you condition PA naturally. The moisture changes the dimensions of the items, making them larger, but it also serves as a plasticiser which gives PA its high amount of endurance. I don't know how fibre filled materials behave in difference to pure ones.
I’m looking forward to when you can objectively test safety of these material for diy purposes, although I agree with your assessment at the end of the video.
Have you tried contacting CR3D for filaments to test?. I'm curious about their PC-ABS. They also have PP filament with 20% glassfiber which sounds interesting
Been very happy with PA6-GF for moderate temperature laboratory applications. But polycarbonate is much easier and faster to print for some uses. I had bad experiences with PA6-CF which is far more brittle than GF version, and it was breaking in the PTFE tube going to print head. GF can be used in AMS but CF can't, so thats another plus.
Could you test out PHA filament next? There is a company based out of California called Beyond plastic that is making filament. I just bought one of their rigid and one of their flexible filament types. I know that there is more companies making PHA.
Nylon PA-6 seems to be the best material to jump to a professional quality. the CF just adds. It can resist all kinds of chemicals. Is there anything the PLA is better for? maybe PLA is more food safe
Great video. Sure fibers can be an issue for health, and 3d printing also releases micro plastics... So just don't print in a living space, vent the room, and when sanding or drilling or even breaking supports use a mask and gloves. As you say, it is the same as MDF or other materials containing fine particles. When embedded in resin it is not such an issue. And if you print CF parts that need to be touched extensively, a small coat of epoxy or thick acrylic coat will do the job.
Very good as always, but one thing bothers me is that you printed the CF 10c hotter than the GF which also explains the over extrusion and the poor layer adhesion of the GF. (Also the flow rate was higher giving the material less time to heat)
With new filaments, I always want to try things, which will most of users do. Minimal drying (if any), probably no annealing (but here I did for my curiosity) and printing with default settings in bambu studio.
Be careful with gloves on a rotating tool - if the glove gets caught it can cause major injury. You can get gloves with breakaway finger sections for this. Thanks again for your great work.
@@MyTechFun Yes, sadly its limited (on a stock device). Bambulab suggests 100-120° bed temp. with glue for their PPA-CF. I guess there are many P1S owners curious if the bed adhesion would actually be sufficient at 100°C. Especially since the filament is a bit expensive to just try it yourself.
When you place 4 split screens are you showing 1 annealed and 1 unannealed test subject for each material? Or are both test subjects showing two annealed for each material?
Interesting, these filaments are very different than normal PA6-CF. The low creeping is nice, but the low impact strength (not as written in the data sheet) in comparision e.g. to Polymaker PA6-CF is really disappointing.
Bambu seems to have a habit of selling "engineering filaments" with properties quite a bit lower than you expect based on the name as they seem to blend them for easy printing on their printers, which I understand, but it means that a Bambu PA6-CF might be quite a bit different than a 3dxTech PA6-CF
I think part of the reason you don't get many views is because of your thumbnails and title. For example, two benchies are not going to attract many viewers. For this video, in the thumbnail you could show a closeup of your scale during shear test and write next to it "MAXED OUT". And for the title you could have "BambuLab PA6 CF and GF | STRONGEST filaments tested so far?" Anything to make the viewer curious. I know you try to keep your titles informative but the reality is you need to have some clickbait

Great tip about using PETG as a well-controlled adhesion and release layer, thanks!
Nano adhesive on Garolite works really well for me.

Commenting to push the videos out there!

Thank you for your awesome videos and your dedication to the facts and testing as an engineer.
For me it's biggest advantage is the temperature resistancy.
I really like your test videos. Wish more people knew about your channel. Keep up the great work. Thanks.
Great work. Hope you can figure out how to print PPACF and review it as well.
The temperature ability is really impressive🎉
Koszonjuk arany barat!
Great information. Thanks for your hard work and efforts!
Thank you for these tests.

Great video; both of these filaments are amazing!
wow these look awesome, thanks! can't wait for ppa and pps :)

Stiffest, not toughest :)
Unfortunately PA tends to creep badly under load.
Which is a big bummer for me
@@warmesuppeand when wet the part dimensions end up all over the place.
Nice Job!

Awesome! I had bought 0.5kg PA6 CF with my A1, was feeling some regret as I heard PETG-CF was better. None of that now!
Nylon PA-6 seems to be the best material to jump to a professional quality. the CF just adds. It can resist all kinds of chemicals. Is there anything the PLA is better for? maybe PLA is more food safe

Great video. One question is why not print at its highest temp for the best results?
higher temps do not translate to better results, it's a bit more complex than that
Be careful with gloves on a rotating tool - if the glove gets caught it can cause major injury. You can get gloves with breakaway finger sections for this. Thanks again for your great work.
Can you please try the bed adhesion of the PPA-CF at only 100°C for all the P1S owners?
P1S bed max is 100°C? Oh, I didn't know about that.
@@MyTechFun Yes, sadly its limited (on a stock device). Bambulab suggests 100-120° bed temp. with glue for their PPA-CF. I guess there are many P1S owners curious if the bed adhesion would actually be sufficient at 100°C. Especially since the filament is a bit expensive to just try it yourself.
When you place 4 split screens are you showing 1 annealed and 1 unannealed test subject for each material? Or are both test subjects showing two annealed for each material?
I see from the summary chart the answer to my question....I asked before thinking :)
cool!
PAHT Cf would be interesting

Well, there goes the claim that the additions mainly help with printability.
Al-G-Rhythm

HPP4-25%GF is better than PA6-GF/CF
not even close
PA6-cf is stronger is my guess
Wtf? The whole point of these video is to provide objective data. There's no room for guesses here.
