CarbonX CF PEKK-C [Aerospace]

CarbonX™ CF PEKK-C [Aerospace] Printing Filament

CarbonX™ Carbon Fiber PEKK-C (PolyEtherKetoneKetone) is one of the highest-performance polymers in world. Aerospace-grade performance made possible by using Kepstan® PEKK and Toray® Aerospace-Grade T800 24K Chopped Carbon Fiber. This compound was created for extreme applications where exceptional thermal, mechanical, and chemical resistance properties are required.

A leading material in the PAEK family, PEKK has exceptionally good mechanical, thermal, and chemical resistance properties. It is also not only substantially easier to print than PEEK, it’s one of the easiest ultra-polymers to 3D print period.

CarbonX™ PEKK products have a lower rate and degree of crystallinity than PEEK, which aids in their ease of printing. However, once printed and annealed, CF PEKK-C parts exhibit superior performance vs. both PEKK-A and PEEK. Easier to print and superior performance!

Filament Specifications:

1.75mm and 2.85mm +/- 0.05mm in diameter

Recommended Print Settings:

• Extruder: 360-390°C
• Bed Temp: 120-140°C
• Nozzle: We currently recommend a hardened steel nozzle with a minimum diameter of 0.4mm
• Other: Ideal layer height is 60% of nozzle diameter. We do not recommend printing layers smaller than 0.2mm with carbon fiber reinforced filaments
• Bed Prep: Nano Polymer Adhesive or 3DXTECH Polyimide Tape gives us the best results
• Heated Chamber: Recommended, up to 130°C if at all possible.
• Supports: ThermaX™ HTS High-Temp Support is designed to work with complex, high-temp materials like this
• Drying Instructions: 120°C for 4 hours

Carbon Fiber Reinforced Filament

What Is It?

Fibers 5-10 micrometers wide made of carbon. The fibers are aligned following the axis of the material.

This, along with their physical makeup, are what give this material its excellent properties.

What Does It Do?

Carbon Fibers demonstrate a lot of desirable material properties:

• High stiffness
• High tensile strength
• High heat tolerance
• High chemical resistance
• Low weight
• Low thermal expansion

How Does It Work?

Reinforcing plastic with carbon fibers produces a 3D printing filament which exhibits the best properties of both the carbon fibers and the plastic of choice.

What Is It Good For?

Ideal for any applications which require light weight and rigidity.

Carbon fiber reinforced parts, designed to use less material and save weight, is extremely popular in aerospace, civil engineering, the military, and motorsports.

Abrasive Material

This material is particularly abrasive among 3D printing filaments. Users may find standard brass nozzles are chewed through very quickly compared to standard wear and tear. When worn through, the nozzle diameter will widen inconsistently and the printer will experience extrusion issues.

Because of this, it's strongly recommended this material be printed through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles can often be inexpensive and easily installed depending on your printer manufacturer's instructions.
