Preparing for Printing

Drying 70-80°C for 4-6 hours
Compatible Build surfaces Glass and PEI film (Using a glue stick or a specialized coating can further enhance adhesion)
Enclosure Not mandatory, but it is recommended
Nozzle Diameter 0.4 mm or larger
Nozzle material Carbon hardened, hardened steel or higher grade nozzles

*Note:

  • Only dry if the filament shows signs of moisture.
  • Drying is not required for the first unpacking unless the vacuum packing becomes damp. Excessive drying can degrade the filament.

Printing with Fibreheart PET-CF

Nozzle Temperature 230-250°C
Build Plate Temperature 80°C
Raft Separation Distance 1-5 mm
Cooling Fan Speed 0-30%
Print Speed 100-200 mm/s
Retraction Distance 1-5 mm
Retraction Speed 1800-3600 mm/min

 

*Note:

  • Printing speeds: Start at the lower end of this range and gradually increase the speed to find the optimal setting.

Moisture Management

Storage Tip Recommendation
Sealed Packaging Store in a sealed aluminum foil bag to prevent moisture
Use Desiccants Add desiccants to absorb moisture and keep the material dry.
Avoid Sunlight & Heat Keep away from direct sunlight and high temperatures to prevent degradation.
Drying Recommendation
Temp 70-80°C
Time 4-6 hours

*Note:

  • Only dry if filament shows signs of moisture.
  • Drying is not required for the first unpacking unless the vacuum packing becomes damp. Excessive drying can degrade the filament.

Troubleshooting Common Issues

Issue Stringing
Reason

1. Printing temperature is too high 

2. Retraction setting is improper

Solution

1. Reduce the printing temperature by 5-10℃.

2. Increase the retraction distance and speed to effectively pull the filament away from the nozzle

 

Issue Popping sounds and poor surface quality
Reason Moisture influence. When the filament is damp, the high temperature during printing will cause the moisture to evaporate, forming bubbles or popping sounds during extrusion.
Solution

1. Dry in oven set at 70-80°C for 4-6 hours

2. Store the filament in a sealed bag with desiccants

 

Other suggestions

Tips
Support structures (if use) Raft separation distance of 0.16-0.18 mm is recommended
Requiring maximum strength Using 100% infill with ±45° infill angles can provide optimal results
