Carbon Fiber PETG

Category: PETG

Material Information

Name: Carbon Fiber PETG
Source: Airwolf 3D
Description:

PETG CF offers a host of additional benefits, thanks to the addition of high-modulus carbon fiber. Enjoy high stiffness without added weight, along with heat resistance, and superior water and chemical resistance and low warpage. While traditional PETG already has a low tendency to warp, the addition of carbon fiber reduces risk of warpage even further, creating tight tolerances and even higher dimensional accuracy. PETG CF is engineering-grade and highly printable, featuring an appealing uniform texture, dark charcoal color and an even, matte finish.

    General Comments

    Characteristics

    • Superior chemical resistance vs. ABS
    • Amorphous structure giving it low, near isotropic shrinkage
    • Low moisture absorption, 3x lower than ABS
    • Very low odor while printing
    • Wide processing ranges from 230-270°C
    • 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.

    Applications

    • Aerospace
    • Civil Engineering
    • Military
    • Motorsports
    • Light weight applications
    • Rigid applications

    Considerations

    • We currently recommend a hardened steel nozzle with a minimum diameter of 0.4mm.
    • Polymer/carbon fiber mixture increases the material’s brittleness

    Printing Skill & Experience - Advanced

    • Ideal layer height is 60% of nozzle diameter. We do not recommend printing layers smaller than 0.2mm with carbon fiber reinforced filaments.
    • Frequent clogging
    • Material is abrasive. We recommend using hardened nozzles, instead of brass nozzles, to reduce print issues caused by worn nozzles.
