I always want to see more PLA tests. It isn't like the manufacturers post clear data on what is what. As a material for mechanical parts PLA has a lot of advantages. the ease of printing is an important one.
Agreed:
1) Ease of printing (especially low shrinkage/warping)
2) Price
3) Strength at RT
4) Modulus at RT
5) Potential for annealing to greatly increase heat deflection temperature
6) Chemical resistance
7) Low toxicity
Great testing, you the man, looking forward to content about the bambu printer and annealing
Just wanted to let you know the audience for the high quality content you produce is still interested in thorough PLA testing!
That's what I keep thinking the past few days.. I'd love to see 5-8+ brands of PLA+ and PLA Pro compared in these tests.
Never a dull watching of your videos, allowing your viewers to ponder how they can make use of these materials in their own projects. Thank you for sharing.
The strength in carbon fiber is getting it to align on the XY axis. Tiny pulverized pieces floating in polymer won't add any strength. It sure looks pretty with it's matte finish. I love your testing. As I have seen with other filaments featuring CF inside, I have yet to see where CF adds any strength. I like the Polymaker materials and I have been a lot of test prints with their CosPLA material for my projects. The PLA Pro is very nice and I find I have to print at 220C to reduce all stringing whereas with their other PLA materials, I find 200-205C is the sweet spot
cf works great for nylons
It do add stiffness to many materials, and at high temp aswell which is important for many applications. Putting it in PLA seems like a waste though, since the base material is shite for useful stuff.
@@garagecedric pla is pretty decent if you don't need temp resistance tbh
You've barely looked then. Nylon and PET are greatly improved by decent CF with better temp resistance, strength, and stiffness. I wonder whether it's an issue of better adhesion to the fibres or ductility avoiding the fibres causing stress concentrations. For whatever reason PLA seems to be a poor matrix material in comparison, usually losing ultimate tensile strength. In the dry state straight after printing, I tested a flexural modulus of 7 GPa on my PAHT-CF!
@@riba2233Don’t like the creep under load, so K never use PLA.
I had your videos show up in my recommend and I’m glad they did. I enjoy your thorough testing procedures, and high quality videos.
Nice test. Thank you.
Good videos. Here are some filaments with very interesting properties. AzureFilm PET Carbon Fiber - very stiff, high HDT and low warp. Aurapol PLA HT110 - high HDT without annealing. Spectrum PET-G HT100 - High HDT. Recreus PET-G CF - High strength. Extrudr Green-TEC pro carbon - Very stiff, high HDT, bio material like PLA. Formfutura ApolloX CF10 ASA - Very stiff and low warp.
The reason for the spool being closer to the resealing end is due to the way it's manufactured. The resealing strip is the bottom of the open bag, the spool is dropped in, then the bag is vacuumed and heat sealed. So when a consumer gets it, there is that extra space on what was the top during manufacturing, but now the bottom for consumers.
Looking forward to the PA test
polylite and polysonic are great and underrated filaments, yes they are a bit more expensive than regular pla but offer really great properties and print quality. thank you for another awesome test, can't wait for more :)
Wow that PLA Pro looks pretty decent. Id actually class that as an engineering material given its performance!
Hi Igor, great video as always. Could you share the link to the printed tool you used for clamping the C specimens while measuring (Creep test)? I'm currently working on a PA6 test video and would like to test creep as well, using your method.
I uploaded it here (bottom of the page, the ZIP file): www.mytechfun.com/video/143
@@MyTechFun Thanks a lot!
Great video, i have a question, that cf filament its a true bblack color, i tested generic filament and creality filament pla cf and color its dark gray,
Im looking for filament dryer for 1kg only. Can you recommend some dryer?
I wonder whether the -CF adds significant abrasion resistance over regular PLA?
Polumaker materials have cardboard spools. For AMS what solutionyou have used for them?
Good work, btw!
I've always had good luck with polymaker filaments EXCEPT for PLA and PLA pro. It warps terribly, and the pla shifts from glossy finish to matte finish depending on flow rate.
I printed polysonic (similar to polylite) in multiple colors, no warping at all, great consistent finish quality and very easy to print. 210-220c, 60c bed etc
What measuring tool he is using for the deflection test?
The sealing machine needs 3-4 inches (7-10 cm) of space between the reel and the fuser.
Looks like some companies find a solution: th-cam.com/video/haDQxl0COo0/w-d-xo.htmlsi=YLOp_6VP_WBN4k8O&t=128
I always wonder what is the base formulation of the PLA in the CF versions. It would seem to make the most sense for them to use an impact-modified formula (ie. Tough/Pro/+) than just a regular PLA. But based on all the tests i see, it seems like the base is a standard PLA. Unless the CF is really that much of a negative impact?
Before watching: CF may be better in rigidity & heat, but worse in other properties (as usually filled filaments are).
After watching: maybe CF filaments do not use same (better) base material as _normal_ or _pro_ filaments. Or CF (or any other filler) just creates breaking points (voids in polymer) instead of binding base material?
Some people dismiss PLA, though it is very strong, cheap, hard and easy to print.
PETG creeps less, but due to flexibility it's not always a good choice for mechanical parts. It doesn't stand much more heat than PLA.
If a printer has hardened steel nozzle and can go to 100/300 C, CF-nylon (CF to make printing easier) might be better option. ASA and especially ABS IMO not so much ;)
ABS and glue sticks for cool plates (again IMO, in 2020's! We have PEI sheets and heated beds!) share the same (hot) place 😈
Edit: will CF become future asbestos? How does file CF _dust_ behave before, during and after printing? It's probably not good for skin, eyes or lungs...
I wanted to try pla CF on my p1s from bambu, but I don't see a real world situation where I would use it ?
only for cosmetics imho
Just a reminder that post-print moisture absorption plasticizes Nylon.
Igen, ezt én is észrevettem hogy a polymaker filamentek Asa -ban is hajlamosabbak a felkunkorodasra és asztaltol valo levállásra....
Now I'm curious how a PLA PRO CF version would act...
I am not, but more curious about their new PA612-CF ;-)
Pla again, i am waiting for those bambulab engineering materials…
Soon, preparing BL PETG (3x)
As always Pla carbon are really disappointing...
May be it has to be annealed to be interesting.
Thanks for the review.
It's easy to say that PLA is bad and that it's not interesting. But it's mostly because the material just isnt having the material properties we need. But it is the dream when it comes to ease of use and printability. PLA is what we want all the other materials to be like, but with the finished result having the mechanical properties of the material we chose instead.
PLA is one of the best filaments for printing and the only reason to use something else is for example because the material is too brittle or too low thermal resistance. A singular weakness that doesnt fit into the intended use. The material is so much superior in terms of ease of use and printability that it is ridiculous. I can without caring about print settings and on maximum printspeeds print squares of 30cm x 30cm with no warping. 100% of the times. I can print tall weird thin sprawling shapes that are usually really difficult in ASA/PC and with no curling/warping. With other materials its simply a lot more difficult to get that exact same result while printing at 200mm/s+. It easily prints 5cm+ bridges without a care in the world. Anything goes. An idiot can print PLA/PLA+. And that is what most of us are. We are tinkerers. We want to spend our lives doing something else. Only like 2% of 3d print users are there for the tinkering and dont care about actual prints themselves.
Now, to convince me that these strength tests are of any use at all, you'd have to convince me that I can easily print these large shoulderpads, helmets or AMS risers etc with zero warping, curling, 99%+ print successrate without a struggle. Large flat peices. Thin overhangs. Tall thin pipes. This begs me to wonder why printability isnt even a metric you care about. It's nothing to you. You just print small flat mechanical parts. This is great, but the most important thing is that you can print the intended part accurately with the material, else it's 100% useless and not even worth considering.
For ASA to reach the same performance as PLA I need to print it at around half speed, I need to prebake the oven for more than 30 minutes, and I need to slow down to less than a third to of PLA speed on overhangs to get an equal result in terms of quality. And it still warps/curls a bit. Some shapes are better avoided and the model cut into smaller pieces to make it easier to print. Nah. What we all want is EXACTLY the PLA printability but just a little more thermal resistance and slightly less brittle. There are already thousands of great options in the printing world to print useless mechanical flat parts. ASA and all the other materials are fantastic at this. But what about the really big difficult full helmet oneshot prints? I want a great cosplay filament. ASA is simply too much work to get a good result, prints too slow and even with great settings it has a too big reduction in size when it cools down which causes warping. This directly limits my creativity and productivity. If only PLA was slightly more thermally resistant would be good. But alas, zero really good PLAs with high thermal resistance seems to exist, and all processes with annealing so far distorts all larger prints until they dont accurately fit what you intended to print.
GIving us lists of specifications is good, but what we are looking for is also printability. It is one of the absolutely most valuable metrics. How accurate and easy are they to print? How good does details come out despite the CF fibers? Is it easily sandable? These are metrics which are CRUCIAL to everyone who is going to print something that isnt a useless flat mechanical stress test/benchmark print. Printability is what makes PLA so popular. It is glorious in that regard but has some severe weaknesses. What everyone is looking for is the next perfect PLA that covers some of its weaknesses. That is all. 99% of people in this world doesnt want to spend their entire lives trying to learn difficult tunings for each print. Sometimes having to reprint things several times or having to cut all prints up to 4-6 pieces and try to weld them together without it being obvious. We want ease of use. Accuracy in print. No warping. No curling. No distorted shapes from annealing. We want to realise our dreams into physical objects just as we imagined them and preferably not just melt like an icecream in the truck. Noone here mind paying an extra 10$ per roll for this. The first company to fix these issues will be billionaires. But almost all PLA/PLA+ are exactly the same, and all other materials have huge downsides generally speaking. Great when push comes to shove, but glaring weaknesses all the same.
What I want to see is the weaknesses of the material. What are the reasons and applications where this CANNOT OR SHOULD NOT be used. In what situations is using another material better. Comparisons. Expert thoughts on the subject. Saying that it is somewhat less tensile-wise than another material is great but can my unmodified ender3 print it well? Does it print extremely difficult large prints accurately? In comparison, how does it work on my X1C? Would perhaps a filament with some carbon help retain the shape better? What alternative could be used if the thermal resistance is too low? These are the kinds of questions people wonder about. The actual real life comparisons and thoughts. I'd love to see more of it. You've used thousands of materials. What made this one great or garbage in your mind? What would you use it for? What should you avoid using it for? Why isnt this in the videos? I know you have these thoughts.
I agree fort he most part but he does talk a lot about printability when he reviews technical materials,
i print gun stiff. its never recommended to use pla cf for anything like that. pla pro is much better
My experience too (that Pro is better)
