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.

Not to crap on a deal, but CF-reinforced filament is not a good thing. They've effectively added contaminants into the filament. Why this matters is clogged nozzles (from my perspective). These tiny fragments of carbon fiber will cause partial clogs and are a pain to deal with.

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 most of my functional parts with PETG-CF on multiple printers over years. Never once had a clog. Like all filaments it's got pros and cons. It makes PETG more rigid and just plain more durable in a lot of applications. Also, I just like the way it looks and feels. Many times the texture hides a lot of the layer lines and leaves a nice matte and sometimes almost metallic finish. It's absolutely not always the right choice, but it's good to have in the arsenal for specific cases, IMO

I used some pla-cf and I got partial nozzle clogs. I even had one after changing filaments, from what I can only assume was some of that didn't get fully expelled. I finally got everything cleaned up and haven't touched cf since.

Imagine if someone tossed a bunch of rebar rods into a cement mixer, then poured that into a foundation. Would that make the foundation stronger? Would that wear out or damage your cement mixer?

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:

https://youtube.com/playlist?list...Z4DGKu__cM

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:

https://youtu.be/m7JAOi4JnBs

I will note that these videos are testing PLA-CF, it is possible that PETG-CF works better.
The testing isn't really that extensive, he just has a lot of fancy equipment. My Tech Fun does more extensive testing as he tests a range of different filaments across a range of different vendors and for a lot more than simply tensile strength.

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.

Yeah, that's a bummer. I've printed probably 50kg of the stuff on several printers and never had an issue. I've read about the clogging issues. I think some brands have a different CF percentage and strand type that can lead to that.

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.

Thank you for the information. I have tried asa-gf and pla-cf, but not the petg-cf. I may have to take it off my "never use" list Smilie.

Be careful when handling any of the CF filaments. I couldn't figure it out for the longest time but I kept getting a sliver feeling on my fingers and where I might have rubbed against something I printed. I couldn't see anything or get rid of the feeling. Then it turns out after reading some articles this is one of the problems with CF filaments.

I will note that these videos are testing PLA-CF, it is possible that PETG-CF works better.
Plastic bonding to CF has a lot to do with wettability and surface energy. Significant molecular differences aside, PLA is printed at a much lower temp than PETG and thus PLA has much less energy available to bond with CF fibers (i.e. not at all). PETG is printed at higher temps and thus has a little more bonding energy with CF. Nylon is on the top of the list as it actually has enough energy at ~280+C to overcome the low surface energy of CF and form covalent bonds.
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.

It looks awesome, ive been using it a lot and haven't had any clogging issues. I consider it an aesthetic filament.

I received my order in 3 days, and this filament prints beautifully with a .4mm nozzle. Just make sure you dry it first.
