Descrizione
CarbonX™ PEKK+CF15 Ultra Polymer is made using PEKK-A [60/40 copolymer] and 15% Toray T-800 aerospace-grade chopped carbon fiber. This polymer is used in a wide variety of end-use applications requiring exceptional thermal, mechanical, and chemical resistance.
The aerospace-grade performance of CarbonX™ PEKK-A (PolyEtherKetoneKetone) carbon fiber is made possible by using PEKK (60/40 copolymer) and Toray T-800 aerospace-grade chopped carbon fiber. This combination creates one of the world's highest-performing polymer compounds. A leading material in the PAEK family, PEKK has exceptionally good mechanical, thermal, and chemical resistance properties. Furthermore, it is not only substantially easier to print than PEEK, but also significantly easier to mold than PEEK.
Premium Toray® Aerospace-Grade carbon fiber reinforcement makes this compound specifically designed for demanding applications requiring extreme thermal, mechanical, and chemical resistance. CarbonX™ PEKK products have a lower melting temperature, speed, and crystallinity than PEEK, contributing to their remarkable ease of printing.
The advantages of the CF PEKK-A [Aerospace]:
- Substantially easier to 3D print than PEEK
- Wide working window from 360-390°C (ideal), up to 430°C if needed
- Tg of 160°C, HDT of 150°C and Tm of 305°C
- Inherently flame resistant (UL94 V-0)
- Low smoke generation
- Excellent mechanical, thermal and chemical resistance
Recommended print settings:
- Extruder: 360-390°C
- Bed temperature: 120-140°C
- Nozzle: We currently recommend a hardened steel nozzle with a minimum diameter of 0.4mm
- Note: The ideal layer height is 60% of the nozzle diameter. It is recommended not to print layers smaller than 0.2 mm with carbon fiber-reinforced filaments.
- Bed preparation: 3DXTECH nanopolymer adhesive or polyimide tape gives us the best results
- Heated chamber: recommended, if possible up to 140°C.
- Supports: ThermaX™ HTS High-Temp Support is designed to work with complex, high-temperature materials like this
- Drying instructions: 120°C for 4 hours
Abrasive material
This material is particularly abrasive among 3D printing filaments. Users may find that standard brass nozzles wear out very quickly compared to standard nozzles. If worn, the nozzle diameter will expand inconsistently, and the printer will experience extrusion issues.
Use hardened steel nozzles with this filament to maximize head life and the quality of your prints!
For this reason, it is highly recommended to print this material through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles are often inexpensive and easily installed, depending on the printer manufacturer's instructions.
