PET-CF, 1.75mm
Pickup available at Fargo. Usually ready in 24 hours.
3D-Fuel PET-CF is a blend of tough PET and carbon fibers. Carbon fiber improves hardness and mechanical strength while helping maintain low warping and shrinkage compared to regular PET.
Due to its dimensional stability and lower water absorption rate, PET-CF is a better choice than nylon for printing functional parts used in high-humidity environments. Also, its high-temperature resistance and low warping make it suitable for printing mechanical assembly parts, such as automotive accessories and fixtures.
Our PET-CF has excellent high-temperature resistance and a soft, matte appearance. Its excellent strength, heat resistance, dimensional stability, and low moisture absorption make 3D-Fuel PET-CF an ideal choice for load-bearing structures or prints used in high-temperature and humid environments.
Polyethylene terephthalate (PET) is a semicrystalline polyester commonly used in soda bottles and automotive parts when reinforced with a fiber filler. This material has an outstanding price-to-performance ratio. When annealed, it exhibits a temperature resistance of over 155 °C and good chemical resistance to common solvents.
Why PET-CF?
PET-CF delivers outstanding dimensional stability and absorbs far less moisture than nylon, making it a smarter pick for printing functional parts in high-humidity environments. Its excellent heat resistance and minimal warping also make it ideal for mechanical assemblies—everything from automotive components to custom fixtures that need to stay strong and precise.

"Takes some tuning to print right. Anyone who complains isnt taking the little bit of time to dial in and not printing with it correctly. Still working on getting some overhangs to print correctly but for basic structural shapes this stuff is insane. Minimal cooling (0 cooling fan when possible) with an enclosed printer and printing "slow" is a must for proper layer adhesion."
"PCTG is always great. PET-CF… I’m not sold on. Maybe I’m missing something. Expensive and not that great…"
"Great stuff that makes great stuff"
"The filament itself prints fantastically. I ran this on my Prusa MK4 at 285C on an 80C bed using a modified nylon preset and no enclosure, and printed a bracket that would go near my hotend. It provided a light, very stiff part. Print this directly from a filament dryer as high as it'll go - my Sunlu S2 will reach 70 and that's what I keep it at. You will need a hardened nozzle. I will caution anyone who buys this that the filament itself is extremely brittle before it's printed - this is not Essentium's fault as it's just the nature of the material. PET-CF from any company is going to behave this way. Just be careful when you remove the loose end of the filament from the retaining holes on the spool and when you load it into the extruder. A reverse Bowden setup will help serve as a filament guide. I have only one minor gripe, which is the packaging. The filament comes in a vacuum-sealed aluminized bag with two desiccant packets, which serves well to keep it dry, but for a $75 spool of engineering-grade material, I would like for that aluminized bag to be resealable. Otherwise, this performs to expectations and I'm seriously impressed with how little tuning I had to do to print this well."
"Prints easy and seems to be very strong. No warping like most nylon cf materials."
