PETG CF15 Basic HS - Filament2Print

PETG CF (carbon fiber reinforced PETG) by Filament2print combines the printability and chemical resistance of PETG with the advantages of 15% carbon fiber reinforcement. The result is a material designed to produce stiffer, more precise, and dimensionally stable parts, featuring a professional matte surface finish and outstanding performance in technical applications.

While standard PETG is a highly versatile material for functional parts, PETG CF takes performance a step further by incorporating carbon fibers that significantly enhance its structural behavior. Printed parts experience less deflection under load, greater stability during printing, and a reduced tendency to warp, making it an excellent choice for jigs, fixtures, mechanical components, robotics, automation, engineering, and functional prototyping.

Furthermore, the characteristic matte finish of carbon fiber provides a high-quality, professional technical look, largely hiding layer lines and giving parts an appearance very close to components manufactured using industrial processes.

Despite being a reinforced material, PETG CF Basics by Filament2print remains relatively easy and predictable to print, far below the complexity of other engineering materials such as reinforced polyamides, polycarbonate, or ultra-high-performance polymers.

Superior Rigidity for Highly Stable Parts

The primary advantage of PETG CF Basic is the significant increase in rigidity delivered by its 15% carbon fiber reinforcement.

The fibers act as a structural reinforcement distributed throughout the polymer matrix, substantially increasing the material's elastic modulus. Consequently, parts experience minimal deformation under mechanical loads, maintaining their precise geometry and dimensional tolerances.

This feature is particularly valuable in applications where dimensional stability is a priority. While standard PETG may show slight flexing under specific loads, PETG CF retains a highly rigid structure, offering performance much closer to that of higher-cost engineering plastics.

This increased rigidity enables the manufacturing of high-precision components, such as:

• ✅ Industrial tooling.
• ✅ Manufacturing templates and jigs.
• ✅ Control and inspection gauges.
• ✅ Structural supports.
• ✅ Automation components.
• ✅ Robotics parts.
• ✅ Lightweight frames.
• ✅ Camera and sensor mounts.
• ✅ Drones and RC vehicle parts.

Reduced Warping and Maximum Dimensional Stability

One of the most notable effects of incorporating carbon fiber is the reduction of material shrinkage during cooling.

When printing any thermoplastic, the material undergoes minor shrinkage as it transitions from a molten to a solid state. This shrinkage can generate internal stresses that cause warping, particularly in larger parts.

Carbon fibers significantly mitigate this effect, limiting material shrinkage during the printing process and enhancing the dimensional stability of the printed part.

As a result, PETG CF Basic offers major advantages over standard PETG:

• ✅ Reduced tendency to warp.
• ✅ Superior dimensional accuracy.
• ✅ Enhanced tolerance retention.
• ✅ Less deformation in large-scale parts.
• ✅ Improved repeatability between print runs.

This is exceptionally beneficial for mechanical parts where accuracy is critical, as well as for large-volume prints where accumulated deformations could compromise assembly or final functionality.

Excellent dimensional stability also streamlines low-volume production runs, where ensuring consistency in part dimensions is paramount.

Professional-Grade Surface Finish

Beyond upgrading mechanical properties, carbon fiber provides a highly distinctive aesthetic that sets this material apart from standard PETG.

Parts feature an elegant matte finish with a very uniform texture that significantly minimizes the visibility of layer lines. This effect yields a much more technical and professional look, closely resembling components manufactured through industrial processes like injection molding.

The matte finish also offers functional advantages. By eliminating harsh glare and reflections, it enhances the visual perception of the part's geometry and simplifies inspection, particularly for engineering components and prototypes.

Thanks to these attributes, PETG CF Basic is ideal for:

• ✅ Presentation prototypes.
• ✅ Engineering components.
• ✅ Production tooling.
• ✅ Laboratory equipment.
• ✅ Automation components.
• ✅ Technical enclosures.
• ✅ Electronic devices.
• ✅ Instrumentation equipment.

The combination of a high-quality surface finish and high rigidity makes this material an excellent alternative when the final appearance of the part is just as critical as its mechanical performance.

Mechanical Properties for Engineering Applications

PETG CF Basic has been developed to offer an excellent balance of stiffness, strength, and ease of printing.

The addition of carbon fiber significantly increases material stiffness, allowing for parts that better withstand mechanical stress and maintain their shape even under continuous loads.

At the same time, the material retains many of the characteristics that have made PETG one of the most widely used polymers in additive manufacturing:

• ✅ Outstanding chemical resistance to various oils, greases, and cleaning agents.
• ✅ Excellent moisture stability.
• ✅ High wear resistance for long-term usage.
• ✅ Solid thermal resistance for functional applications.
• ✅ Superb interlayer adhesion, producing strong, homogenous parts.

As with most carbon fiber reinforced materials, the increase in rigidity results in a minor reduction in ductility compared to standard PETG. However, this behavior is highly beneficial for most technical applications, where minimizing flex and maximizing structural stability is the primary objective.

Consequently, PETG CF Basic is an excellent solution for manufacturing components that require precision, stiffness, and durability without the printing complexity of advanced engineering materials.

Print with Confidence and Precision

PETG CF Basic upholds the high quality standards that characterize the entire Basics by Filament2print range, delivering stable and repeatable performance from the first layer to the last.

Every spool is manufactured under strict quality controls to guarantee a constant diameter, uniform roundness, and neat winding—essential factors for smooth filament feeding and stable extrusion.

Uniform winding prevents snags, overlapping, and tangling during printing, minimizing the risk of failures on long-duration prints. This level of reliability is critical in professional environments and print farms, where process uptime is just as vital as part quality.

Additionally, a consistent diameter ensures uniform material flow rate throughout the entire print. This translates into more precise extrusion, excellent detail definition, smoother walls, and fewer under-extrusion or over-extrusion issues that could otherwise compromise the part's mechanical strength.

Another highlight of PETG CF Basic is its excellent interlayer bonding. Despite containing 15% carbon fiber, the material formulation has been optimized to maintain a strong bond between layers, yielding highly robust and homogenous parts under mechanical stress.

The result is parts with excellent surface quality, high dimensional accuracy, and consistent mechanical properties, providing the confidence needed for both functional prototypes and end-use parts.

Full Compatibility

PETG CF Basic is compatible with the vast majority of FDM/FFF 3D printers capable of reaching standard PETG printing temperatures and equipped with an abrasive-resistant nozzle.

Each spool features a high-quality plastic reel, designed for reliable performance in standard printers as well as automated filament delivery systems.

This spool is fully compatible with Bambu Lab AMS and most multi-material systems on the market.

Compared to cardboard spools, plastic spools offer major advantages:

• ✅ Superior resistance to impacts and deformation.
• ✅ Immune to ambient moisture, preventing the reel from warping during storage or use.
• ✅ Smoother rotation, reducing friction during feeding.
• ✅ More precise dimensions, enhancing compatibility with automated systems.
• ✅ Greater durability and potential for reuse.

Combined with the excellent filament winding, the spool ensures continuous and stable feeding throughout the print, reducing the risk of errors even on long-duration print jobs.
