PEEK-CF

PEEK-CF material printing requires extremely high temperatures and specialized high-temperature equipment. Recommended nozzle temperature 400-450°C, print bed temperature 100-220°C, chamber temperature 80-220°C. Drying at 100-120°C for 6-8 hours is required before printing. Cooling fan should be OFF. Specialized high-temperature 3D printers must be used, such as CreatBot PEEK-250/PEEK-300 series.

PEEK-CF significantly improves mechanical properties through carbon fiber reinforcement: tensile strength increased from 75 MPa to 90 MPa, Young's modulus from 4400 MPa to 7500 MPa, flexural modulus from 2500 MPa to 5500 MPa. Meanwhile, HDT increased from 150°C to 200°C, thermal expansion coefficient is significantly reduced, and dimensional stability is better.

PEEK-CF material has strong hygroscopicity. Moisture will vaporize during high-temperature printing, causing bubbles inside the print and silver streaks on the surface, seriously affecting mechanical properties and appearance quality. Drying at 100-120°C for 6-8 hours can effectively remove moisture from the material.

PEEK-CF is widely used in multiple high-end fields due to its excellent comprehensive properties. Typical applications include: ① Aerospace - engine peripheral parts, structural brackets, heat shields; ② Medical devices - artificial bones, surgical instruments, implants; ③ Automotive manufacturing - engine parts, bearings, seals; ④ Electronics - chip carriers, connectors; ⑤ Precision machinery - high-rigidity structural parts, tooling fixtures.

PEEK-CF material has strong hygroscopicity, and proper storage is crucial for ensuring print quality. Storage methods: ① Unopened filament should be stored in a cool, dry place (temperature 15-25°C, humidity <30%), avoiding direct sunlight; ② Opened filament is recommended to be stored in a sealed bag with desiccant; ③ If not used for a short period (more than 24 hours), it is recommended to remove the filament from the printer and store it sealed.

First layer adhesion is key to successful PEEK-CF printing. Recommended measures: ① Heat print bed to 100-220°C, maintain stable temperature; ② Use 3D printing spray, PVP glue stick, or specialized adhesive to treat the bed surface; ③ Reduce first layer print speed to 15-20mm/s, with nozzle height slightly lower than normal; ④ Set first layer line width to 120-150% of nozzle diameter; ⑤ Use brim with 8-12mm width.
