CARBONX PEEK+CF20 - Black / 1.75mm / 500g - 3DXTech

Package contains: 1 x CARBONX PEEK+CF20 - Black / 1.75mm / 500g - 3DXTech

CarbonX? PEEK+CF20 is one of the leading polymers in FFF/FDM 3D printing. Made using 20% high modulus chopped carbon fiber for exceptional stiffness, strength and dimensional stability.
PEEK+CF20 is one of the highest performing thermoplastics ever invented. It is used in some of the most demanding applications from industries such as automotive, aerospace, defense, semiconductor and oil/gas.
The properties of CarbonX? PEEK+CF20 include:
Superior mechanical properties, even at elevated temperatures
Excellent chemical resistance
Low coefficient of linear thermal expansion (CTE)
Near-zero moisture absorption
Low smoke and toxic gas emissions
PEEK+CF20 Thermal Properties:
Thermal deflection temperature (HDT) of 320°C
Glass transition temperature (Tg) of 143°C
Melting temperature (Tm) of 343°C
PEEK has incredible resistance to hydrolysis in boiling water and superheated steam (useful for sterilization and autoclaving) at temperatures above 250°C
Typical PEEK+CF20 applications include:
Gaskets, gears, bushings, bearings, pumps and compressor components
Industries served: automotive, aerospace, defense, semiconductor, oil and gas
Printing with CarbonX? PEEK+CF20
PEEK has a melting temperature (Tm) of 343°C, so you'll need an all-metal extruder that can reach (and maintain) temperatures up to 400°C or higher depending on your specific printer. Every printer, and printing environment is different and you'll have to tinker to find a process that works for you. One of the most difficult aspects of printing with PEEK was getting it to adhere to the build plate.
Note: PEEK+CF20 has a tendency to stick to metal (PEEK loves metal). Be sure to completely purge the extruder before it cools down or you run the risk of permanent clogging.
Filament specifications:
Diameter: 1.75 mm (+/- 0.05 mm)
Recommended print settings:
Extruder: 385-415°C
Platen temperature: 130-150°C
Nozzle: we currently recommend a hardened steel nozzle with a minimum diameter of 0.4 mm.
Other: the ideal layer height is 60% of the nozzle diameter. It is not recommended to print layers lower than 0.2 mm with carbon fiber reinforced filaments.
Platen Preparation: We recommend the use of an adhesive or poly tape
Heated Chamber: Recommended
Media: The ThermaX? HTS is specially designed to work with complex, high-temperature materials such as 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 are chewed up very quickly compared to standard wear. If worn, the nozzle diameter will expand inconsistently and the printer will encounter extrusion problems.
For this reason, we strongly recommend printing this material through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles can often be inexpensive and easy to install depending on the printer manufacturer's instructions.
