3DXTECH CarbonX Carbon Fiber Nylon Gen 3 2.85mm, 500G 3D Printing Filament

Don't listen to the bad reviews, if they had problems it's due to user error. I have item I printed with this year's ago that even thrown in my junk drawer for years still looks as good as the day I printed it. It's very strong quality and is amazing.

This was my first time printing with CF filament and I had a lot of nozzle clogs at first. I followed some suggestions and played with settings and I haven't had a jam after using about 1/4 of the spool. I'm using a 0.4 mm tungsten carbide nozzle on a Prusa MK3S+.The most important setting I think is to use zero retraction. Second, I slowed down the speed considerably, using a "maximum volumetric speed" around 4 mm^3/s. Third I used a high printing temperature. I also print a short "draft shield" using a tall skirt very close to the part to keep the air around the first layer hot and avoid warping. So far I'm really liking the filament.

Prints really clean, but literally has sections that fail while others are bonded really well. But as you can see in the pictures. A failed print is a failed print. It flakes and is very brittle. I've tried different extruder temps and followed the recommendations. Probably will not use this specific filament again.I have reached out to the manufacturer they advised the filament was "too dry" and recommended letting it sit out, chamber temp between 30°C and 80°C.Pictures are after following recommendations.Filament seems to appear wet in certain areas and isn't actually wet(before printing). Doesn't seem like it is consistent throughout the spool.

So I bought this as an alternative to the Nylon CF I normally buy as it was out of stock. I should have waited. None of my prints have been quality in the least bit and the amount of failures from this material have basically costed me an entire spool. I’ve changed speeds, temps, layer heights and nothing has helped. I literally printed a cylinder at the most basic settings and it failed.

I had nothing but problems using this filament. It came wet, would spring off the spool and get tangled, very brittle snaps if you bend it slightly, jams up in the nozzle. Once i spent hours messing with it I got it to print a part and the quality was horrendous. JUNK

I haven’t tested it yet but ask the 3dx filament I’ve used has been far superior to any other brand I’ve ever tried.

printing on a custom ender3 at 260c hot end a6 nozzle and 85c bed pei on glass and Elmer's purple glue stick. dehydrated filament @160deg f before printing. 4hr bake in oven @190 deg f. amazing filament. check out their Pekk-A or Pekk-c this is my next purchase.

I dried it at 90c for a few days and it prints extremely well. But comes unspooled as a twisted mess, forcing me to manually unspool and feed the machine as I print. May have been a bad batch but very bummed about that
