PET-CF

PET-CF

$0.6 per gram

Engineered for Performance.
Think PET meets carbon fiber: the result is a filament that delivers next‑level rigidity (bending modulus ~5,320 MPa), outstanding strength (tensile ~74 MPa, bending ~131 MPa), and serious impact resistance (~36 kJ/m²). It’s built to hold tight in parts that bear real-world loads without bulging or giving way.

Stable in Tough Conditions.
Low moisture absorption means it won’t swell or degrade in damp environments. It also shrugs off heat and humidity—great for gear that works as hard as you do .

Precision That Holds Shape.
Carbon fibers lock into the PET matrix, suppressing warping and creep. Your parts stay dimensionally true—even across long spans or critical interfaces.

Matte Finish, No Fuss.
A subtle matte surface reduces glare, masks imperfections, and offers a clean, tactile feel—so your parts look professional straight off the print.


🔧 Best For:

  • Functional load-bearing parts: brackets, beams, structural mounts

  • Damp or warm environments: outdoor fixtures, automotive housings

  • Precision tools & fixtures: jigs, alignment aids, thermal-resistant components
