- To carbon fiber or not, that's what i'm testing out so grab a bear and find out!
I had a lingering covid infection so i changed it up and made it voice friendly let me know if you like it.
In this test i used PETG from prusament and tested it vs this carbon filled petg: www.amazon.nl/gp/product/B07S...

great video! I was expecting these differences and was looking for more information, thanks!
No surprise here. Thanks for doing the testing, I like seeing these kinds of videos.
some good tests, but as was stated earlier, it would be better with a quality CF filament. You can get good cheap 'standard' filaments, but once you start adding fillers like CF, you have to be careful. most of the cheaper ones will use milled CF powder, just to say it has CF, but all that really does is make the filaments brittle with little added benefit (other than looking pretty 😀).
I personally like 3dxtech. Wish prusa would make a petg-CF (kinda surprised they dont)
I'm also not a big fan of using just the hard-break numbers. Sure that's still good to know, but in most functional parts, once you've stretched past a certain point and the part is permanently deformed, then in most cases it's considered 'broke' in terms of it's usability.
Still appreciate the channels that take the time to do the tests like these. Thanks.
Prusa now offers PETG with carbon fiber. I bought a spool but havent printed it yet.
He is using peak force, not "point of hard break" as far as I can tell. When the part elongates, the force drops.
Pretty much validates what I expected, I've just started printing with petg but wouldn't use it for functional prints as is, but cf petg looks to act identical to a good pla with the added heat resistance petg
actually very helpful for my research! I was hoping to see if CF PETG would be better than PETG for my specific use of printing a guitar core, I believe the stiffer CF will likely give me better results with the constant pressure from the strings and less warping over time than standard PETG.
Yes those are the key reasons to go for CF filled filaments
The biggest reason I use CF Petg is it's much better resistance to warping during print
Great background! Where are the cabinets and table from?
Thanks! Cabinets are from a dutch company called HBM (chinese importer with a store) and the table is something i made myself th-cam.com/video/p0Lp6XvdlcQ/w-d-xo.html
Gracias. Thanks. Merci.
Wish you had used a more name brand CF Petg, as the formula for the petg itself could vary greatly.
True! Maybe in the next comparison 🙂 thx for the tip
Love cfpetg:)
The slow mo really sounded like a bomber or artillery right? What would you like to see next?
I want that BEER! 🤪
Sure! Come over 😅
the only reason I can really think to use CF PETG is for 1) color 2) if you don't want to dry the filament as much
3 warp free printing ;)
Video i am looker for good job
I read that as "I am hooker" lol
Not sure why so many people think cf added to these materials would make it stronger, adding a stronger material to softer material will just make the material weaker in area's where the cf is most concentrated. If you did a compression test you would find the cf mix slightly stronger but when you have to bend or pull the material it is going to be weaker where ever the cf is concentrated in the material, this will be the case in every mix, Nylon cf will have the same reaction.
True, i do think the main benefit is lack of warping using cf nylon. And it's stiffer but lacks the strength.
You trade ultimate tensile strength (toughness) for Young's Modulus (stiffness), so if you need a part that is as stiff as PLA but with a higher heat resistance, it would be worth it.
Adding a strong material to a weak matrix is what the whole concept of composite materials is. It works, provided that the fibres are long enough to transfer load to and from the matrix. There's a big difference between chocolate grade CF filaments and high quality (and expense) engineering CF filaments. Unfortunately this one looks like one of the yum cha PETG-CFs that don't make any claims about performance.
I don't get CF. I have some samples so I tried it. It looks exactly the same as any black matte PLA.
Mostly stiffer result and a bit more heat resistant that's about it
How does PA12CF15 compare to PETG-CF? Is PA12 stronger?
I will have to test it 😉
are you from the netherlands ? When i hear youre accent ;) i should think so )
Almost 🙂 Belgium
what i find is petg thick wall will crystalize and shatter like glass, cf stops that and actually make the part less brittle
Try printing a clear PETg - Dry it first too.
I am finding clear or even translucent PETG less brittle.
It does still depend on print settings. If u try it let me know. Because what I have found may be coincidental.
In my experience, PETG shatters when dropped PETG CF does not.
Are all PTAG carbon fiber filaments? What is the temperature of the hot plate and nozzle for carbon fiber printing? And what should be the material of the nozzle?
You need hardend nozzles, temp is depending on the brand but for petg cf it's 60c bed and 225 nozzle in my case
A little more time showing each result i testing would be nice. It was sp short that almost impossible to see without rewinding and pausing. Interesting channel tho, and result 😊
Noted and thanks! This was my first, already show them longer on the resin testing but gonna compile them to bar graphs so it's more nice to look at.
@@NoizieWorks ok, awesome. Keep it up 👌😁
My wife chose 'good looks and stiffness' 😳😏
🙈😁
The CF PETG has a better hardness. That makes it more fragile or in eng. terms - lower tensile strength.
That's what she said! 😅
@@NoizieWorks Oh, hey there! :) Do you like beets?
Love them
You're jumbling up all the material properties. I think by fragile you mean brittle, which has nothing to do with tensile strength. Hardness is strongly correlated to tensile strength, so no, higher hardness does NOT mean lower tensile strength, literally the opposite.
It's because this is not really carbon fiber filament, but rather it's PETG sprinkled with carbon fiber fragments. The strength of normal carbon fiber is in the structure of the material which is ruined when it's only chopped up and mixed into something else.
Not really...a good CF filament does have real advantages. They are just quite expensive. This is not one of them. Having chopped CF whose fibers align during extrusion does offer high modulus as well as tensile strength. 3dx-tech is an example of a brand that can really put down the numbers.
Video too old. There is no VS anymore. One can get CF in nearly every filament.
Yup! New video is in the planning
