What is Carbon-fiber PETG?
PETG-CF is PETG filled with chopped carbon fiber. The fibers make the part stiffer and more dimensionally stable, and they hide layer lines behind an even, matte black surface. It is abrasive to print, so we run it through hardened steel nozzles.
Design tips for Carbon-fiber PETG
- Use carbon fiber where stiffness matters more than flex: the part resists bending but is less forgiving of sharp impacts.
- Keep walls at 1.6 mm or more.
- Avoid knife-edge features; fibers make very thin tips fragile.
- For heat above 80 °C, move up to carbon-fiber nylon.
Nozzles: 0.4 mm as standard, 0.6 mm for larger parts printed faster. General tolerance is ±0.5% with a lower limit of ±0.5 mm. More in the design guide.

Carbon-fiber PETG 3D printing FAQ
Is carbon-fiber PETG stronger than regular PETG?
It is stiffer and holds its shape better, so brackets and mounts flex less under load. Regular PETG bends more before breaking, so it is the better choice for parts that take sharp impacts.
What does a carbon-fiber print look like?
A uniform matte black surface with a fine texture. The carbon fibers scatter light, so layer lines are much less visible than on standard plastics.
Is this the same as a carbon-fiber composite part?
It is a printed plastic reinforced with short carbon fibers. It is much stiffer than unfilled plastic and far cheaper and faster than laid-up composite parts, which makes it ideal for brackets, fixtures and housings.
How much does carbon-fiber 3D printing cost?
The price comes from the grams of material and the hours of printing for your part. Upload your file for an exact price in seconds; carbon-fiber PETG is the lowest-priced carbon-fiber option we offer.
