IEMAI Carbon Fiber Polycarbonate Filament 1.75mm, Enhanced Strength Toughness PC-CF 3D Printer Filament, High UV/Heat Resistance Carbon Fiber PC Filament 1kg(2.2lbs) Spool, Black

UPDATE: i use a 0.4mm hardened steel nozzle without any issues. the stuff prints amazing this is the first time i ever printed in anything other than PLA, PETG, or TPU. i needed a functional strong part for an e-scooter that would be exposed to the elements and thought now would be the time to get a better filament. it was relatively easy for me to get it going and i did not have to do much to get printing. i have to say it is easily the strongest filament i've ever used. where PLA just easily snaps and breaks, this holds up. it can be more brittle when it does give way, where PLA is more likely to flex. the bed adhesion is not good, as is to be expected. this is countered with a heated enclosure. I do not own one so i used about 3 candles inside with a small opening for fresh air. this allowed me to get enclosure to about 33C. put pre-heated the bed, removed filament from packaging and placed it back inside the box, inside the enclosure on the heated bed, for 2 hours before printing. i printed with bed at 110C and nozzle at 285C. I would have used hotter nozzle temperature but i couldn't for the life me get the printer higher than that (even with modifying the firmware). Even though I didn't get it as hot as i would have liked, it still held on and bonded nicely. only downside is that i ordered black but it appears more grey than black. very happy with the filament

This filament prints really well, delivering strong, durable parts with excellent heat and weather resistance—perfect for outdoor use. I've been using it for a project in my cars trunk. Just be sure to keep it dry, as it can get brittle and snap if exposed to moisture. Overall, a great filament for functional prints!

Nothing good to say about this ... couldn't get it to stick to the bed even with Magigoo and heated chamber ... i run PA612-CF at 45c bed normally and works like a charm .... why doesn't this be the same instead of 100c bed ???

i made some hex shelves it worked pretty well a bit to much spiderwebs though

I'm on my 2nd kilo of this PC-CF and I've got to say, I (mostly) love it. I've printed 2 V-Spoolers with it - one original, one of the larger X models, as well as a Pastalite respooler (what can I say, I was evaluating options). Gorgeous prints each time. Bed adhesion and warping isn't great on its own, but adding a coat of Magigoo PC solves that. Nice, deep black color with smooth finish. Overall, solid quality stuff. Like most filaments of this type, please dry it before you start using it and store it in something air-tight. Make sure your chamber is heated to at least 40-45C before sending the job. Prints great on my X1C.
