CarbonX CFR Carbon Fiber Reinforced Co-Polyester Filament 750gms spool.



Made in the USA using premium PETG and High-Modulus Carbon Fiber (not carbon powder or milled carbon fiber).  CarbonX CFR is an improved CF reinforced 3D printing filament vs. the competition.  This filament is ideal for anyone that desires a structrual component with high modulus, excellent surface quality, dimensional stability, light weight, and ease of printing.  






CarbonX CFR PETG is suitable for use in practically any desktop 3D Printer that has a heated bed.  Please note – carbon fiber reinforced filaments are abrasive and can wear out a brass or aluminum nozzle. We recommend Hardened Steel Nozzles when using CFR.

Benefits of CarbonX CFR-PETG include:

  • Superior Chemical Resistance vs. ABS
  • Amorphous:  Low and near isotropic shrinkage
  • Low moisture absorption:  3X lower vs. ABS
  • Very low odor emitted during printing
  • Wide processing range:  230 – 270?C 

Chemical Resistance:  Unstressed tensile bars molded of PETG exhibit good resistance to dilute aqueous solutions of mineral acids, bases, salts, and soaps, and to aliphatic hydrocarbons, alcohols, and a variety of oils. Halogenated hydrocarbons, short chain length ketones, and aromatic hydrocarbons dissolve or swell the plastic. 

New Data:  We updated the mechanical and thermal data on our carbon fiber grades.  You can see the new data HERE on our blog.

Recommended Print Conditions:

  • Extruder:  Ideally 230 to 260°C
  • Platform Temp:  70 to 90°C
  • Platform Prep:  Clean glass w/ Kapton Tape, PVA-based glue, Hairspray
  • Nozzle:  We currently recommend minimum 0.40mm orifice.  
  • Carbon fiber filament is more abrasive than unfilled materials, so extended use will result in more wear on your nozzle.

  1. WOW, Just WOW 

    Posted by Amancue on 21st Dec 2016

    So I just opened up my CarbonX to print up some mods for my printer,.. its what I bought it for. I used a profile I’ve been tweaking for PETG for a while didn’t change anything and it;s amazing sooo smooth and flat the sides seem like I used a much lower layer height than I did.

    all I can say wow,.. just wow

  2. Decent Filament 

    Posted by Jeff on 4th Nov 2016

    This is an ok filament, it is consistent, prints decently once you get your settings right and makes for some stiff strong parts. The parts are more brittle than they would be over regular PETG, but that stiffness is needed in certain applications.

  3. 0.2mm nozzle 

    Posted by Toshio Fuji on 22nd Oct 2016

    This is my 2nd report.
    I could print this filament with 0.2 mm nozzle, and result is very good. With 0.4 mm nozzle, this filament makes some blobs and strings by its high viscosity, so I need to remove them after printng everytime. However with this 0.2 mm nozzle, the problem became much smaller.

    Also surface became much smooth and beautiful. Of cource it need more time to print, but it was roughly 2 times (2 hours to 4 hours), and not 4 times (cross sectional area of 0.2mm nozzle is 1/4 of 0.4mm nozzle).

    There is no stuck trouble through 20 hours printing.


  4. Awesome. 

    Posted by Unknown on 16th Oct 2016

    I’ve been using this material professionally for almost a year. It took me a while to figure out the perfect settings. Hardened steel nozzles are a must. Any inconvenience there is well worth it. This is a heavy duty, high- performance material. The carbon fiber is a huge selling point for my customers, and with the right setting you can get a beautiful carbon fiber look to the top and bottom of your parts. Side walls aren’t as smooth as regular PETG- but again- the performance is worth it. I’ve made $30,000 worth of parts from this material- and I’ve had nothing but positive feedback from my customers.

  5. Strong and easy to print 

    Posted by Unknown on 1st Aug 2016

    I use the material to print a Quad-copter part that I design and I needed it to be very strong and able to take a few hits. it works really well and is lighter than the Carbon Fiber PLA that I was using before. the stiffness of the material and ease of printing made it a great material for my needs. my part was a 14 hour print.

    I use a ROBO 3d and I printed at 250/80 again no issues.
    I am using a E3D V6 stainless steel .2mm nozzle I bought the hardened nozzle that was suggested but the E3D V6 seems to be working fine. 

    be careful when you take it out the box it spring off the spool a bit but noting dangerous.

  6. Strong 

    Posted by RockScout on 20th Mar 2016

    I’m just finishing be second roll. There was a learning curve with this material. The settings I’ve settled on are: 
    extrusion multiplier: .87, automatic extrusion width
    Temp: 265/80 with cooling fan. (COOLING FAN NEEDED to prevent edge curl)
    ooze control: 3/3,000/.4 coast

    This material will destroy a brass nozzle in 8-10 hours. I haven’t nailed down exactly how long it takes to wear out a hardened steel nozzle, maybe two rolls. So factor in ~$12 nozzle cost per roll.

    Like all PETG it sticks right to Kapton tape and is dimensionally stable- no shrinking. 

    Four stars because the filament diameter isn’t perfectly consistent, and the material is so stiff it springs off the spool, which invariable causes problems, and requires special attention.

  7. Easy to use, and beautiful finish 

    Posted by Toshio Fuji on 18th Mar 2016

    This filament is easier to print than ABS because of no warp. Also finish is very beautiful (rough cloth like), so I need not sanding or painting. 

    I also tried CF-ABS by 3dxtech, and most features of this are closed to it. Actually I used same print setting to both filament, and there is no print error ever.

    I am using this filament in my DaVinci 1.0 with custom 0.3mm stainless nozzle, and Simplify3D.

  8. Best Carbon Fiber PETG 

    Posted by Haz-Matt on 12th Oct 2015

    This is the best carbon fiber filled PETG on the market, and believe me I have tried them all. If you are looking to make an strong, light, durable part, with an awesome finish, then buy this PETG. Many times I have had to use 40-100% infill just to get the strength my part needed. I have now reduced my print time, without sacrificing strength with as low as 15% infill. This also makes a 1.65kg spool go a long way. I have printed this at many different layer heights from 0.12-1mm using a E3DV6 Volcano hotend, and it looks great at any resolution. If you can print ABS you can print this Carbon Fiber PETG. Just make sure you use the recommended nozzle size per 3DXtech.

  9. The Muscle Car of Filament, 3DXMAX PETG!! 

    Posted by Scott Lograsso! on 7th Aug 2015


    I am writing this much earlier that I expected to but I cant resist because this filament blew me away as soon as the first “green dropped” ( starting the first print ) 

    I must say first I have been printing with a few brands of PETG for months. For the best results I created a new setting profile from the abs setting, then adjusted bed temps simpler to PlA and then flowwed manufactures speed and print temp. I have also found that PET’ filaments can be “gooy” or stringy but reducing extrusion or temp was nit good for bonding, in stead I have reduced the nozzle diameter setting slightly and adjusted reaction length speed, lift and restart. so I could maintain higher temp and flow 

    in many applications PET’ plastic has wonderful to work with and the results outstanding, it “WAS” my second favorite, 3DXMAX PLA being first, That changed When I hit go on CFR PETG!!! Using my PET+ setting 3XMAX redefined what a good first layer for PET looks like, 3DXMAX PLA did this for its rivals as well. It was flawless right until the last few layers when just goober or 2 clung on, but thats why I like my test file file, its meant to be tough, and those little bits flaked right off…. I have not tryed the wrong any other settings for this filament and I recommend researching and establishing a devoted PETG set up and then make awesome good looking things with this stuff that can be very functional

    PETG is!!! VERY STRONG!! but with strength commonly a material is not stiff. When I the first print cooled and I removed it ( that test piece file). The first thing I always do after inspecting and knocking off any goobers is BREAK IT…. THAT IS TOP PRIORITY!!!! (ALWAYS WHERE SAFETY GLASSES WHEN BREAK STUFF to test of course!!!) I didn’t think would be able to snap it with just my hands like PLA, since a PETG has yet to fail there, because the usually bend enough and tense up….. I think this one to bend…. I dont have strong hands but I tried, I might have been hopeful. I though to go to the garage and WIN but then I decided to prepare a proper test, since it bent about as much as piece of putruded Carbon Fiber would!!!!! have not tested yet. I actually placed a coat of XTC 3d on it. I noticed with 3DXMAX PLA the epoxy helped emulate a real CF layup. 

    I have since that first print, a few days ago printed 8 corner brackets and 2 stepper mount plates for 80/20 10 series. its been a busy week with building and car maintenance but I look forward to sharing more. ..

    I am planning use this in R/C chassis modification and conversion as well as internal reinforcement for 3d print infill for various mechanical and structural parts ( custom shaped reinforcement filler) and tooling ( clamping and position)!. I am however impressed from the increased stiffens while retaining strength with such low weight. impressed to the point I am going to begin testing light and medium duty automotive parts 

    like steel with a pinch of Vanadium steel, the Carbon fiber 3DXMAX PETG powered this to the top on my favorite filament. with an impression boost in functional printing performance and end use all while rcopsing its own unique look( I felt it was a tad bit more reflective than CFR PLA. like comparing regular Black PLA to Black PETG.

    I end with 
    THANK YOU THANK YOU THANK YOU!!!! Excellent work and development from 3DXTech!!!

A versatile middle ground between PLA and ABS.

PET-G Is stronger than PLA but easier to print with than ABS. The glycol in this material makes the filament less brittle and resistant to water, chemicals, and solvents. It is naturally clear, making it the go-to filament for translucent prints. 
The strength and durability of a PET-G filament vary depending on the brand. An easy way to check if one PET-G is stronger than another is by comparing the tensile strength value of each filament. If printed in a sterile, FDA-approved environment, PET-G can be used to create food-safe prints.

Due to its strong and durable nature, PET-G can be difficult to finish with post-processing methods such as sanding. Prints may also be difficult to paint or glue together. Depending on printer and slicer settings, you may experience small hairs over the surface of prints caused by stringing. These can be removed with a heat gun or lighter.

Used for: Water Bottles, Plant Pots.

1 review for 3DXTech CarbonX Gen 3 Carbon Fibre PETG 750gms 1.75mm 3D Printer Filament

  1. 3 out of 5

    Rafael Heeb (verified owner)

    It prints really well. But the filament has a lot of random high spots where it was spliced. Some of them are so high that they get stuck in the extruder or, in some rare cases, in the bowden tube. So far, I had to scrap about 30% of all printed material just because it caused prints to fail. Not great for very expensive material.
