CarbonX™ CF PEKK-A Printing Filament
CarbonX™ PEKK+CF Ultra Polymer is made using Arkema Kepstan® PEKK-A [60/40 copolymer] and 10% high-modulus chopped carbon fiber. This polymer is used in a wide variety of end-use applications where exceptional thermal, mechanical, and chemical resistance is required.
CarbonX™ Carbon Fiber PEKK-A (PolyEtherKetoneKetone) is made using Arkema Kepstan® PEKK and is one of the highest-performance polymers in world. 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.
Benefits of CF PEKK-A Includes:
- Substantially easier to 3D print than PEEK
- Wide processing window from 345-375°C
- Tg of 160°C, HDT of 150°C, and a Tm of 305°C
- Inherently flame resistant (UL94 V-0)
- Low smoke generation
- Outstanding mechanical, thermal, and chemical resistances
1.75mm and 2.85mm +/- 0.05mm in diameter
Recommended Print Settings:
- Extruder: 345-375°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 140°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
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.
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
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.
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.
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.
Use hardened steel nozzles with this filament to maximize toolhead life and quality of your prints!
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.
