PEEK-GF

PEEK-GF material printing requires extremely high temperatures and specialized high-temperature equipment. Recommended nozzle temperature 400-450°C, print bed temperature 110-220°C, chamber temperature 80-220°C. Drying at 100-120°C for 6-8 hours in a forced-air drying oven is required before printing. Cooling fan should be OFF.

PEEK-GF significantly improves mechanical properties through glass fiber reinforcement: tensile strength increased from 75 MPa to 84 MPa, Young's modulus from 4400 MPa to 7500 MPa, flexural modulus from 2500 MPa to 4800 MPa. Meanwhile, HDT increased from 150°C to 202°C, with better dimensional stability and electrical insulation.

PEEK-GF 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.

PEEK-GF is widely used in multiple high-end fields. 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 with excellent electrical insulation; ⑤ Precision machinery - high-rigidity structural parts.

PEEK-GF 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%); ② Opened filament is recommended to be stored in a sealed bag with desiccant; ③ If not used for more than 24 hours, remove the filament from the printer and store it sealed.

First layer adhesion is key to successful PEEK-GF printing. Recommended measures: ① Heat print bed to 110-220°C; ② Use 3D printing spray, PVP glue stick, or specialized adhesive; ③ Reduce first layer print speed to 15-20mm/s; ④ Set first layer line width to 120-150% of nozzle diameter; ⑤ Use brim with 8-12mm width.
