Our take on the Carbon Fiber Reinforced PETG 3D Filament

This is a 1.75 mm PETG filament blended with finely milled carbon fiber, sold on a cardboard reel. The carbon adds stiffness and dimensional stability to PETG's toughness, and the matte finish hides layer lines on functional parts. It suits makers printing jigs, fixtures and structural components who have a hardened nozzle. Compared with plain PETG it is stiffer and more dimensionally accurate but more abrasive on the hotend; compared with nylon-CF it is easier to print and less moisture-sensitive.

Pros
  • Carbon fiber boosts stiffness and rigidity over plain PETG
  • Strong layer adhesion and low shrinkage
  • Matte surface hides layer lines
  • Good dimensional accuracy for mechanical parts
  • Runs on most 1.75 mm FDM printers
Cons
  • Carbon fiber is abrasive and wears standard brass nozzles
  • PETG still absorbs moisture and needs dry storage
  • Matte finish can show extrusion inconsistencies
  • Not intended for flexible or high-impact parts

About the Carbon Fiber Reinforced PETG 3D Filament

This is a carbon fiber reinforced PETG filament for FDM 3D printers. Finely milled carbon fibers add stiffness, dimensional stability and rigidity, while the PETG base keeps its toughness and durability.

The PETG base gives strong layer bonding, reduced shrinkage and reliable extrusion. Prints are consistent and warp-resistant. The surface has a matte finish with less visible layer lines, so functional parts look clean and technical.

It suits mechanical components, structural parts, jigs, fixtures and other parts that need more rigidity, heat resistance and dimensional accuracy. It works with most 1.75mm FDM 3D printers. A hardened nozzle and stable temperature control are recommended.

Questions and answers

Do I need a hardened nozzle?
Yes. The milled carbon fiber is abrasive and will wear a brass nozzle quickly. A hardened steel or ruby-tipped nozzle is recommended.
How does it compare with plain PETG?
It is stiffer and holds dimensions better, with a matte finish instead of gloss. Plain PETG is tougher and gentler on nozzles.
Does it need drying before use?
PETG absorbs moisture, so dry the spool if prints pop or string. Store it sealed with desiccant between uses.
What can I print with it?
Mechanical components, structural parts, jigs and fixtures. It is not suited to parts that must flex.
What is in the box?
One spool of filament in a vacuum-sealed bag, packed in a cardboard box, with a black plastic spindle mount.
What temperature should I print at?
Use a stable temperature within the PETG range your printer handles well, with part cooling kept moderate for layer bonding.
Where is the Carbon Fiber Reinforced PETG 3D Filament cheapest?
At Deal.ai, for $38.99, as of our latest check.
