Material Information

Name: PETG
Source: Airwolf 3D

PETGs (or copolyester) are glycol modified PETs; the modification is done by adding a second glycol during polymerization. The resulting molecular structure is irregular and the resin is clear and amorphous with a higher glass transition temperature of 80°C. PETGs can be processed over a wider processing range than conventional PETs and offer good combination of properties such as toughness, clarity, and stiffness.

    General Comments


    • Superior Chemical Resistance
    • BPA Free
    • Amorphous: Low and near isotropic shrinkage
    • Low moisture absorption
    • Very low odor emitted during printing
    • More flexible than PLA or ABS
    • Can be printed with lower bed temperatures than ABS
    • Does not need an enclosure
    • Superior chemical resistance to ABS
    • Very low odor while printing
    • Amorphous structure giving it a low, near isotropic shrinkage
    • Low moisture absorption, 3x lower than ABS
    • Wide range of processing from 230-260°C
    • Superior ductility vs. ABS


    • Low shrinkage (minimal warping) is ideal for printing larger prototypes
    • Prototypes which are shatterproof or translucent
    • Mounts, jigs and fixtures
    • Headlight covers
    • Food and liquid storage


    • Stringing may occur when printing due to moisture absorption. Drying is necessary prior to printing.
    • Poor bridging performance.

    Printing Skill & Experience - Intermediate

    • PETG can jam the print head if printed too hot.
    • If the printer is closed, it is recommended to keep the enclosure door / top open, if possible, to prevent filament form swelling and to maximize the print quality.
