CCTREE 3D Printer Carbon Fiber Nylon Filament 1.75mm, 1kg(2.2 lbs) Spool, Lightweight high Strength&Heat Resistance, 3D Printing Black PA CF Filament

As another reviewer mentioned, the PA-CF prints OK, but the printed parts break apart easily in the hand. This DOES NOT have the strength of a typical PA-CF. I dialed in my settings on the Bambu X1C, it printed very smoothly and looks great, but when you flex the part in your hand it breaks apart at multiple layers. It's almost as if there's just no layer adhesion, and I've tried printing at all temps between 250 and 290. Between 250-260, the part really is super weak. This filament is not usable.Also, the plastic spool warped really bad in my filament dryer, and it was only set to 70C. Nylon should come on a heat-resistant spool. This is terrible.

I struggled for a couple of days with this filament after getting it, but after I solved adhesion, this filament provided strong parts for a fraction of the cost of other Nylon + Carbon Fiber filaments offered on Amazon.The main "trick" for getting layer adhesion on my textured PEI build plate seemed to be drying the filament ahead of time. My filament arrived already wet, and I had to put it in a filament dryer overnight to take if from 35% relative humidity to 13% relative humidity. I am running the prints directly from the filament dryer, using it as the spool holder.Another important factor was the surface preparation. I don't use glue stick for any other filaments on the PEI textured build plate, but this PA+CF formulation won't stick to the build plate without it.Make sure you have a hardened nozzle or this filament will quickly wear it out. You might want to also ensure that you have hardened extruder gears, as PA+CF filament will even wear a notch in soft brass extruders.Amazon had me rate the sheerness of this filament, and it should be noted that it's not at all sheer, it's got a rough texture that makes a good slip resistant handle. It DOES have a tremendous ability to withstand sheering forces.

I printed at the higher end of the suggested printing temp and while the part turned out much finer than other brands, the part audibly crinkled as I tugged on it lightly attempting to remove it from the print bed and as I pulled harder it simply crumbled. I was using a .8mm hardened steel nozzle.As usual, the cheaper the product from china, the lower the quality. Just practice with esun PA-CF and turn your finished parts out with matterhackers/basf/atomic/coex3d

I ordered the PA-CF (Nylon) and even after extensive drying, I could pry it apart with my hands. I have a Bambu X1 Carbon, and this stuff simply falls apart at all temps.

Wants to warp no matter how you print it. Tried everything. Warps so hard it pulled my voron magnetic bed up off the magnet . If you can tolerate the warp you'll find it has almost zero strength . 1in thick solid bracket snap cleanly at any layer with little force. Tried various temps, nothing mattered. Garbage filament

This filament could be used for nothing. If able to successfully print it will crumble like dry fall leaves. An absolute waste. How this has almost 5 stars has got to be manipulation.

I have a heated enclosure, set he bed temp to 90C, slowed the print speed to a crawl and I was eventually able to achieve good looking prints that will crumble in your hand leaving clean separation between the layers. The manufacturer recommended print speeds and temperatures is only located on the outside of the card board box the spool comes in, not on the spool itself (kind of an industry standard) I dried the spool for a total of nearly 4 days at 66 C (the best my filament dryer can do in a 64 F room) and printed directly from the dryer so moisture should not be an issue. I do not know what else can be done to make this filament work. For now I am going to put it in the dry box and search for a PA-CF with better reviews and quality standards.

I was able to successfully print this on my Qidi xmax3.1st. Tried without a heated chamber. The print curled up like a potato chip. (Failed)2nd Tried with heated chamber set at 53C. Print complete. However, the finish is subpar compared to other PA-CF filament out there.The print was extremely stiff. No layer adhesion issues @ 310C, from the stiffness, this is my opinion, I don’t think it will have good impact load resistance.I would not recommend this PA-CF is you need a good looking part or need good impact load properties.
