How To Choose The Right Carbon Fiber Filament

Diameter Tolerance

The diameter tolerance of a carbon fiber filament is crucial to consider if you want to print a 3D object with minimal effort. A unit with high dimensional tolerance will make sure that no nozzle jamming and clogging occurs during the printing process.

The best carbon fiber filament offers enhanced diameter stability so that the printing doesn’t stop in the middle of the process. It will ensure that the planes and corners are equal, and no manual finishing of the 3D object is required after being printed.

The diameter tolerance varies from unit to unit. Most filaments come with an accuracy rate of at least +/- 0.02 mm. The higher the rate, the better your printing experience will be.

Quality of Carbon Fiber

Since you are looking for a carbon fiber filament, the quality of the material is a prime factor. The better the quality of the carbon fiber, the finer will be the 3D printout.

A filament with high purity raw material and PLA carbon fiber will provide low shrinkage and help you print a long-lasting 3D item. This PLA material filament is also toxic-free and biodegradable, imposing no harm to the environment or humans.


Carbon fiber filament can print rigid, thin, and hollow 3D objects, but the filament can be damaged due to moisture and water. So, high-quality packaging is necessary to maintain the quality of the filament and have a satisfying printing experience.

The recently launched high-end carbon fiber filaments are vacuum-sealed with desiccant to ensure that no moisture gets into the pack. And some renowned brands even dry the filaments for 24 hours prior to packaging to remove water and moisture from the unit.

If you don’t want to use the filament for 3D printing all at once, then you should definitely choose a unit that comes with vacuum-sealed packaging.


The compatibility of the carbon fiber filament doesn’t necessarily relate to printing performance. Still, if the filament doesn’t work on your 3D printer, then a superior quality unit will also be useless, right?

Most 1.75 mm carbon fiber filaments are compatible with almost all renowned 1.75 mm specification 3D printers and 3D printing pens. However, check the products’ compatibility list before purchasing and pick one that is right for your 3D printer.

Final Word

Carbon fiber has become a must-have filament for 3D printers. Printing rigid and durable 3D objects has become much easier thanks to carbon fiber filaments.

The best carbon fiber filament offers outstanding layer adhesion along with maximum diameter tolerance stability.

Choosing a product from the vast array of filaments available in the market could be somewhat challenging. So, we present you with some of the top-tier units in the market, any of which will make an ideal filament for your 3D printer.
