A YouTube channel has also gone through a lot of testing and inspection and found that the plastic will shrink away from the cf particles, leaving tiny air voids. The testing he did also showed that CF filament is actually weaker than non-cf filament (at least in PLA).
In short, it sounds good on paper, but is a complete waste of money and time over standard filaments.
I print PETG-CF and ASA-CF, both with a 0.4 nozzle, and have never had a clog. Also print a bunch of ABS-GF, same nozzle, no clogs. It hides layer lines better and prevents warping, especially during annealing. I've printed large pieces, like 290 long x 310 wide x 150 tall and without a additive it will want to pull up on the corners. Using CF/GF prevents that. With that said CF DOES make the part overall weaker. It's a trade off, the part is slightly weaker but is more dimensionaly accurate and less prone to warping.
I wouldn't bother using CF in PLA....it doesn't make sense as you're not gaining much as it doesn't easily warp. If you want a better surface finish just use Matte PLA and smaller layer height.
Comparing adding rebar to concrete to CF to filament is also not the right analogy. It's more like adding gravel to concrete which in the right ratio does make the concrete stronger then not having the gravel.
tl;dr: CF makes the filament weaker overall but does increase accurate dimensionallity and reduce warping. It also hides layer lines better.
There is no reason to assume every filament has the same material properties as PLA.
Community Reviews
Creality Hyper PETG CF is mainly an aesthetic and functional PETG blend with a matte, earth tone, near metallic finish that can hide layer lines and make parts look more manufactured. It also adds rigidity, better dimensional stability, and improved warp resistance, which suits functional parts and janky gears more than pure strength gains. Several prints ran cleanly on 0.4 mm nozzles, though clogging and partial jams are still a recurring concern, especially with smaller nozzles or poor setup. Drying the filament first and using a larger nozzle can help, making it a useful specialty spool when the finish and stiffness matter.
Common Questions (5)
It can be more clog-prone than standard PETG, but many users report printing it on 0.4 mm nozzles without clogs. A larger nozzle like 0.8 mm, limiting volumetric flow, and slightly raising temperature can help reduce jamming.
It is mainly useful for parts that benefit from higher rigidity, better dimensional stability, reduced warping, and a matte, near-metallic finish that hides layer lines. It is often chosen for functional parts, car parts, and "janky gears" rather than for pure strength gains.
Not necessarily; several comments say CF can make the part slightly weaker overall while improving stiffness, dimensional accuracy, and warp resistance. The practical tradeoff is better shape retention and surface finish, not guaranteed higher tensile strength.
It can shed carbon fibers when handled, and some users report a persistent sliver-like sensation on fingers after contact. Wearing care when handling prints and filament is prudent.
Yes. Drying it first is recommended, and one user specifically reported that it prints beautifully on a 0.4 mm nozzle after drying.

The fact is, we carefully arrange the rebar rods before pouring concrete over them for a reason. The arrangement of the rebar is what strengthens concrete, not the mere presence of rebar. On top of that, the concrete sticks to the rebar; the rebar rods have ridges for the concrete to anchor on.
But with most cf filament, you just wind up with random cf threads throughout the printed layers, not a structural arrangement. On top of that, some common filament types(like PLA) don't adhere to the CF threads, so you wind up with bubbles in the printed part, and the cf threads sitting in the print, but not physically bonded to the plastic. Since they're smooth, there's nothing really providing structural support there. In fact, by causing voids to form in the print, you're actually reducing the strength, not increasing it.
Someone tested this extensively, you can see it here:

There are some filament manufacturers that sell "carbon core" filament, which aligns the CF threads in the center of the filament, which is a far better arrangement than just random CF threads scattered throughout the filament. It also protects your hot end nozzle, as the CF is surrounded by a plastic sheath.
You can see a video of that type of filament being tested here:

I will note that these videos are testing PLA-CF, it is possible that PETG-CF works better.
The biggest benefit of fiber reinforcement is dimensional stability, tensile strength is pointless in most situations. As you are going to run into warping issues long before you risk snapping a part in half. So a part is only as good as it's ability to resist warping. Which is the primary benefit of CF reinforcement, and even PLA benefits from.
There is a reason everyone who thinks fiber reinforcement is pointless is always referencing this one guy. And that is because he is the only one who thinks that. Which is because he is wrong.
For me it's not a daily driver, it's real specific use cases, like anything for my cars or needs to be more rigid. IMO it really shouldn't be compared to PETG as it behaves and looks completely different. While the underlying plastic is still PETG, everything else about it and the parts you print are very different.
If nothing else, aesthetically, it's completely different than PETG. From just an aesthetic standpoint, a functional PETG part usually screams 3D printed where if done right a PETG-CF part can look a lot closer to something manufactured.

Furthermore, CF rods act as nucleation sites for some of the semi-crystalline polymers (PET, PA6, PPA, etc.) during slow cooling and they actually enhance stiffness by interlocking crystals and transfer loads into the CF rods. Although PLA is also semi-crystalline, it has almost no bonding to CF and slips instead of transferring load.
Thus, PLA is one of the worst plastics to add CF to. Glass fibers work better due to increased bonding.
