Creality Hyper PA6-CF Carbon Fiber Nylon Filament 1.75mm 1KG, 3D Printing Material Halloween Gifts with Engineering-Grade Strength, Heat Resistant, Low Warp for Functional Prototypes&Industrial Parts

Really good color quality and the filament looks great when printed. No brittleness issues and it didn’t clog during any of my prints. Feeds smoothly, doesn’t tangle, and overall prints strong and sharp thanks to the carbon fiber mix. Good value for money and perfect for detailed or structural prints.

This filament is impressive. I printed a py2a model and it worked perfectly. Annealing is also easy to do. You need an enclosed printer, and the filament must be dried thoroughly, but if you can manage those two things, this stuff prints very well. A bit of glue stick on the print bed keeps it from fusing permanently to the PEI or whatever other surface, it's also pretty good at keeping the nylon stuck to the print surface. I have not used this for high temp uses at all so I can't speak to temperature reliance of the plastic but there are published numbers you can look up which show it is better than many other filaments. Some advice: Take your time and print this filament slow. Set your print temperatures toward the higher end and disable fans aside from the very shortest of layer times. You can get away with something like 30% fan in short bursts but you really don't want to create a temperature shock on the model while printing with this material or it will warp due to the internal stresses. There are harder and more rigid filaments, and there may be filaments with better properties, but for the price and relatively common print temperature range, this is absolutely incredible filament you can rely on to just work for functional prints. BE AWARE of the carbon fiber filaments, they do pose a health risk. You must perform sanding and other post processing outside with a respirator or you run the risk of inhaling small fibers, which can pose a health hazard. You should also wear gloves and scrub all of the surfaces of the model smooth before handling, as it will embed small fibers in your fingers just off the printer, but they generally pose a small risk only if they embed deeper into the skin for some reason, they usually fall out. The surface can also be made safer to handle by covering it with a coating. Finally, annealing the prints improves some of their mechanical properties. I would recommend you purchase a filament dryer which can also cure the models you print. Annealing is not necessary for good mechanical properties, but it is absolutely fundamental that you run the filament out of a dryer if you want it to print properly.

Edit: The plastic spool seems to no longer warp while being dryed even up to 130C, and can be dryed and used effectively now The filament needs to be dryed before usage, however the spool is made of low thermal resistant plastic which causes the spool to warp out of shape while being dryed anywhere between the BambuLabs recommended temperatures between 100-120C for 10 hours. This causes the spool to malfunction in the AMS of Bambu printers making the AMS incapble of feeding and/or retracting the filament as normal. If one way or another you manage to get the filament to feed properly while printing though, successful prints are of the highest strength and quality you could ask for. Truly the most tragic filament, all they had to do was put the filament on a proper cardboard spool and it would have been flawless.

Adding a few layers for certain decor helps strengthen the print. Using it with the wood filament helps strengthen the pints

This filament was great, had 0 issues on my a1 as a noob user with the ams lite and fit right on, didn’t need an adapter. No clogging, no tangles yet, worked with all the default settings. My only complaint is that the color change is VERY gradual unless you’re printing huge. The ad picture for the filament listing is kind of deceiving with the mask sitting next to the roll because printing that size, the mask would be like one color with a hint of change. I get that its an example of the colors of the roll… but its not exactly what i was looking for. As a note, the print in the photo was about 78g of filament

One of my favorite "fast" PLA's to print with. Always quality but drops will shatter the print.

Since this filament is cheap it's great for testing prints. I don't really have much use for a white filament otherwise - so economically its nice that I don't mind if a print fails or doesn't turn out how I expect. It prints very well, but I've had some lifting on the edges - as I have with other Creality filaments - so thermal shrinking is a problem here. If you keep a moderate bed temp, lower hot end temp, and print slow it tends to be pretty flawless

Quality printing. For proper bed adhesion go 5 degrees higher than recommended top temp and bo fan for first couple of layers. Excellent strength and finish.
