    3DXMax™ CFR Carbon Fiber Reinforced PETG 3D Printer Filament

    Made in the USA using premium Eastman Amphora™ PETG and 20% High-Modulus Carbon Fiber (not carbon powder or milled carbon fiber).  3DXMax™ CFR-PETG 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.

    Our premium PETG 3D printing filaments are made using Eastman Amphora™ 3D Polymer.

    3DXMax™ 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 our A2 Hardened Steel Nozzles - HERE

    Please note:

    • 200g is supplied loose spooled, no reel, vacuum packed.
    • 750g is supplied on a reel, vacuum packed.  

    Benefits of 3DXMax™ CFR-PETG include:

    • Made in the USA
    • 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 

    Recommended Print Conditions:

    • Extruder:  Ideally 230 to 250°C; up to 270°C  
    • Platform Temp:  70 to 90°C, up to 110°C
    • Platform Prep:  Clean glass w/ Kapton Tape
    • Nozzle:  We currently recommend minimum 0.35mm orifice.  
    • Carbon fiber filament is more abrasive than unfilled materials, so extended use will result in more wear on your nozzle.  

    We finally have the data back from the lab on our 3DXMAX® Carbon Fiber 3D Filaments.  This data covers the most commonly requested mechanical property tests - Tensile Strength, Modulus, and Elongation.  It also covers the two primary thermal properties - Heat Distortion Temperature (HDT), and Glass Transition Temperature (Tg).  

    What you see below is an excellent representation of why we have multiple types of carbon fiber filaments.  No two are the same in a given property or well-suited for a particular application.  For example, if strength is your main criteria, then our CF Nylon would be the material of choice.  However, if stiffness was the main driver, then CF-PETG would be it.  However, if short-term thermal properties are your main concern - then it's CF-ABS.  This is one of the reasons why we have multiple materials - there is no "one size fits all" solution in engineering materials.  

    Converted to PSI for our MPa challenged friends, the Tensile Strength of these grades are:

    • CFR-Nylon:  9,267 psi (pretty darn nice!)
    • CFR-PETG:  8,049 psi
    • CFR-PLA:  6,947 psi
    • CFR-ABS:  5,221 psi

    Again, here's the Tensile Modulus (Stiffness), converted to PSI.

    • CFR-PETG: 714,746 psi
    • CFR-PLA: 694,875 psi
    • CFR-NYLON:  636,280 psi
    • CFR-ABS: 518,509 psi

    Test Methods

    We printed these test specimen using ISO test specimen on a Makergear M2 with an E3Dv6 extruder.  Temps were all a bit different due to the various polymers we tested, but we targeted the middle of the recommended range for the print settings.  One downside of this approach is that we might have been able to achieve a little higher mechanical properties had we pushed the temp limits and ran them as hot as possible.   Instead, we chose to have the data represent an average print on an average machine.  With that said, you might be able to achieve higher properties than us if you print the bars hotter (better layer bonding), but this is the approach we decided upon.  

    • Printer:  Makergear M2
    • Extruder/Nozzle:  E3Dv6 with an A2 hardened steel nozzle 
    • Extruder Temps: Varied, depending upon the material (see above)
    • Layer:  0.2mm
    • Infill:  100%, +/- 45 degree
