Nylon 12 Carbon Fiber (Polyamide): a strong lightweight high-performance thermoplastic

FDM Nylon 12CF is a carbon-filled thermoplastic with excellent structural characteristics. The material is comprised of a blend of Nylon 12 resin and chopped carbon fiber, at a loading of 35% by weight. This combination produces one of the strongest thermoplastics in the FDM material portfolio. It has the highest flexural strength of any FDM thermoplastic, resulting in the highest stiffness-to-weight ratio.

Appropriate uses include strong but lightweight tooling applications and functional prototypes in the aerospace, automotive, industrial and recreational manufacturing industries.

Nylon 12 CF (carbon filled)


Standard lead time About 4 working days, depending on part size, quantity, number of components and finishing degrees.
Standard accuracy 0.012 in (± 0.3 mm) - may vary depending on geometry.
Layer thickness 0.010 in - 0.254 mm
Minimum wall thickness 0.039 in - 1 mm
Maximum build dimensions Dimensions are unlimited as components may be composed of several sub-parts. The maximum build envelope is 3 x 2 x 3 ft (914 x 610 x 914 mm).
Surface structure Unfinished parts typically have a rough surface but all kinds of fine finishes are possible. FDM parts can be smoothed, painted and coated.

Design Guidelines

Files Requirements

Files Requirements

We strongly recommend to our customers a good preparation of digital 3D files. This preparation will ensure the quality and optimal 3D printing of your files.

If your file has multiple assembled parts that contain overlaps, it is important to unify into a single solid file. If you are working with surface files and shells, it is important to transform the surface models into a solid format.

The quality of 3D files is very important. We prefer to work with parametric models. This allows us to optimize the resolution when creating .STL files for the best results.

If you decide to transform a parameterized file yourself into an .STL file, you must ensure that you have enough resolution to keep most of the characteristics. Otherwise, there is a risk of losing important functions of your 3D model.

We accept file formats: Solidworks, Catia, STEP, IGES, Parasolid (X_T, X_B), and .STL high resolution.

Wall Thickness

Wall Thickness

All processes have manufacturing limits. With 3D printing, the wall thickness has a direct impact on the selection of layer thicknesses. A simple rule to follow is to make sure you have wall thicknesses 4 times greater than the layer thicknesses.

Surface Quality

Surface Quality

The selection of layer thicknesses will influence three important aspects of a 3D printed part.

  • The production time can be greatly accelerated by increasing the thicknesses of the layers.
  • We can considerably improve the surface finish of a part by reducing the thickness of the layers and / or by orienting this surface in the Z axis.
  • You can increase the mechanical resistance of a function by orienting it in the X and Y axis.
Geometric Tolerancing

Geometric Tolerancing

All manufacturing processes have a variation. When programming 3D files for 3D printing we make sure to manage the shrinking effects inherent in thermoplastics. We have a multitude of controls that reduce variation and provide exemplary repeatability with all of our technological processes.

Depending on the geometry of the parts, the tolerances vary around:

  • ± .005 inches for parts less than 3 cubic inches
  • ± .0075 inches for parts less than 5 cubic inches
  • ± .015 inches for parts less than 10 cubic inches
  • ± .030 inches for parts less than 20 cubic inches
  • ± .045 inches for parts less than 30 cubic inches

When producing multiple parts, it is possible to make changes to 3D files to achieve better accuracy.

Orientation orthogonal to the XY fabrication plane is important to maximize the accuracy of the part. We obtain greater precision in the X and Y axes.
