How strong is PC-CF? Prusament carbon fiber PC blend (PolyCarbonate)

[@MyTechFun]

There is an important update to this video. If we turn off the part cooling, we will get much better layer adhesion. Measured: kzbin.info/www/bejne/lX-UfoeNfNaln6s

[@watwsplace8614]

Yes that is exactly what I have found, On Priline CFPC

[@NexGen-3D]

Nice report, I agree with your findings, the PC-CF layer adhesion is affected by the part cooling fan, more fan, less strength, if you print in a heated chamber with no fan, it gets very strong, I anneal all the time, print at 101% size and then cook it for 8hrs at 120C and you end up with a part that's spot on.

[@mezl]

in the result graph, it will be more clear if you can compare it with PLA/ABS/ASA as well

[@Artur-iy6nz]

Please make a comparison between PC, PA, PC-CF and PA-CF. It would be an amazing video to know the differences in terms of mechanical properties and applications of each materiall

[@avejst]

Great test and interesting as always Love that you test so many aspects of the filament Thanks for sharing your experiences with all of us 🙂

[@garagecedric]

Thanks for the data, i really like PC-CF, very easy to print, also with a great print finish, and also pretty cheap for what you get. One big factor is that its not moisture sensitive, which is a big plus over Nylon. I especially enjoyed that you tested the annealed parts, i havent seen any data on it yet, will definitely try that.

[@beepboop8184]

Can it be printed without enclosure? I have my Prusa sitting on my working desk, I don't have place for enclosure but I also don't want to breathe in some nasty stuff.

[@jedisct1]

Love that filament! Very easy to print, yet strong and resistant to high temperatures.

Great video. Your test methodology is really good; very well done !

[@JazAero]

I do a lot of printing in PC CF, On my Mark 3. I have always found the best settings to be 275°C Hot end , 100°C Bed, And absolutely NO cooling whatsoever ! This is extremely important or you will not get Optimal layer adhesion With this material. The print will still look great it but will have no Strength. Additionally I use a water cooled hot end Which also avoids any extra air movement from the Hot end cooling fan. And a much more consistent Print at the higher temperatures. . Water cooling also avoids any filament jams from heat creep at the high temperatures.

[@TheJacklwilliams]

Excellent information! I have to ask since I’ve barely scratched the surface on using different filament types. What is the driver that has you using this? I’d think it’s important considering a water cooled hot-end, etc…. Thank you!

[@JazAero]

@@TheJacklwilliams "What is the driver that has you using this?" I'm not quite sure understand this question. Are you referring to my water cooled hot end ? Because if you are the system is one I designed myself. And does not require a "driver"

[@f1hotrod527]

Thanks for actually doing the testing on this filament. For some reason CNC Kitchen will not release his review video for the carbon fiver version of PC blend.

[@f1hotrod527]

I see the very poor layer adhesion is why he probably did not post his video. I purchased a roll of this. I need to install my all metal hot end and upgrade the firmware on my CR10 to print at the higher temperatures. I will really need to design structural parts with this filament carefully due to the poor layer adhesion.

[@MyTechFun]

I was waiting that video myself. I saw in his latest video that he is sponsored by Prusa, that is very rare, that they sponsor anybody. But I hope that is not the case, that he don't present CF because of weak layer adhesion, must be some other reason.

[@AndrewAHayes]

This could not have come at a better time as I was actually looking online at my list of preferred manufacturers for PC-CF and PETG-CF and NYLON-CF when the notification came for your video, I was surpised to learn that with Prusament you dont get a full 1Kg of material but the combined weight of the spool and the filament is 1Kg, is this typical of most manufacturers, I had assumed that I have been getting 1Kg of filament and after just weighing a roll of Esun filament I get a full 1Kg of material although my regular filament brand is Ziro but I dont have a full roll at the moment to check. I have bought Prusament in the past but just because of particular colour I needed, I feel conned and if this practice is the same with the regular Prusament in PLA and PETG I wont be buying anymore.

[@Anonymous-qx5uk]

Prusament filament is listed as net weight. PLA and PETG are listed as 1kg. ASA for example is 850g due to it being a less dense material. So you are not getting less volume, a spool of ASA will print the same amount as a spool of PLA.

[@brynparrott7361]

If you happen to use the satin PEI bed plate, then glue stick is not required for PC Blend CF. It also prints near perfect using standard prusa slicer profile. Impressive !

[@jedisct1]

Prusa still recommends glue stick on the satin bed plate to avoid damaging it.

[@thelightspeed3d712]

This is my favorite filament. I use it for anything mechanical

[@ImpossibleLink]

[@Eronpas]

Id be very interested in a comparison of different cf filaments. Ideally with the same amount of fibers. I like cf petg and I'm not sure if pa or pc would be a significant improvement (considerig price and hydroscopy)

[@delarois]

Great video, highly detailed experimentations! Witch material you think would be best to use for rope pulleys (for use under water)?

[@MyTechFun]

I am not sure at this moment, probably filaments which are less sensitive to moisture (but not sure if same case with water). So probably not Nylon. If temperature is below 30°C even PLA can be used.

[@dylanb9341]

Great video! I was wondering if the enclosure temp was enough to achive the best layed adhesion, also as others have already said, im not sure if the cooling fan is needed for this engineering grade materials. If each layer can cool in a longer period of time you can get better adhesion on Z axis (this is where enclosure temp can help), CNCKitchen did a video about this. Obviusly if you do this with PLA it will deform, but based on the results of the video i handles temperature really good so you wont be reaching the HDT

[@EvilWiffles]

Cooling fan is very useful when bridging. I set it to only be on during the first layer of bridging, acting as a sacrificial layer. Cooling fan used during printing of the support interface is also important because it makes removal of supports much easier (I always 100% need this when dealing with Nylon as it's a pita to remove supports otherwise).

[@mario_nuevo]

IMO, you shouldn't use part cooling when printing PCCF. That could be the cause for that weak layer adhesion. I only use a bit of part cooling for bridges.

[@MyTechFun]

I will try to print those two vertical test object without cooling, I will add results in description or as post on KZbin. Prusa Slicer default setting turns 20% fan on those 45° overhangs.

[@girenloland]

Prusa themself seems to think so....

[@Todestelzer]

I’m printing PC-CF a lot for a customer. Not much shrinking and a nice finish. But expensive….

[@RcFabian94]

[@NexGen-3D]

The Glue Stick is not to help it stick, its to help it release, if you don't use glue stick, you can kiss your bed good by :)

[@aaron12693]

Regarding your videos about the food safety of 3d printed parts, does the high deformation temperature of this material make sterilization possible? It seems like you could boil or even autoclave these parts and avoid the problems with bacterial growth in between layers.

[@MyTechFun]

Yes, I gave a plan to test them in autoclave. This and Engineering Filaticum.

Have you looked at the addnorth pc blend from Sweden? It has way better stats. Would love to see a real life test.

[@danieldeutschen7714]

My Hevort parts consumed two spools of PCCF, printed at 285/110/~50. The higher chamber temps helped a lot with layer adhesion. When we pushed to ~60° chamber, the layer adhesion went insane. Supports became super hard to remove and the parts became almost unbreakable by hand. Also, it is quite hydroscopic and became much stronger once dried. Overall a good material, but I don't like that they used cheap carbon instead of high modulus fibers. The modulus of this material is barely higher than the unfilled PC Blend, so I don't think that the price is justified.

[@DKFX1]

What is the strongest most unbreakable filament with a 300 degree printer and an enclosure, in your opinion?

[@danieldeutschen7714]

@@DKFX1 highly depends on your application. If you just want your parts to be "unbreakable", go with TPU. A good PP might also work. If your parts need to be stiff but aren't loaded constantly, PACF might work. For printer parts, go with PCCF. Whats your application like?

[@DKFX1]

[@uhu4677]

If this had better layer-adhesion it would be the perfect filament. Good mechanical properties, easy to print, and very high temperature resistence. Maybe they can mix it with something else to fix that one flaw.

[@Todestelzer]

If you add cf to a filament the layer adhesion always suffers. But it’s still a very nice filament. Printing it a lot recently.

[@Juhsga]

My experience with my PLA is it shrinks about 3%. Well 3% for circles and around 2% for length, width, height.

[@rich1051414]

PLA does shrink, but printers are calibrated to compensate for PLA. (Until geometry undermines that) Theoretically it is possible some plastics would appear to expand, if they shrink less than PLA.

[@baderalafghani4564]

Do PID at 285 to avoid this issues in the future

[@Gallardo6669]

Nice job. BUT: I would run 3 samples of each material, better average result

[@matjazmkl]

What is the best material for printing Prusa printer parts if you want to have higher quality than the original PETG? Is the CF PCBlend a good option to have some more headroom with temperatures in the enclosure, or are the specific 3d printing stresses not good for CFPCB?

[@MyTechFun]

Not sure about other parts, but I had problems with extruder PETG elements on MK3S inside enclosure. For example PINDA proble holder deformed a little. So I reprinted them from PCblend CF. Great material easy for printing, but you need hardened nozzle and print close to 300C with very minimal part cooling.

[@kwinzman]

@ E3D original sock: Each sock is made using a non-stick silicone resin, and can be used at a constant temperature of 300C without degradation. Going hotter than 300C is not recommended; this results in slow ageing, and eventual weakness and splitting. The socks are rated to last for at least 100+ hours of use.
