4. Preparing for Printing
Drying: PET materials are sensitive to moisture, which can affect the performance during printing and the quality of the final product. Ensure the material is dried. Typically, it's recommended to dry at 100-120°C for 4-6 hours before printing.
Bed Temperature: Recommended bed temperatures range from 70°C to 90°C to
help the first layer adhere better.
First Layer Settings: The first layer is critical for a successful print. Ensure the bed is level and the first layer print speed is slightly reduced to enhance adhesion.

6. Moisture Management
Sealed Packaging: When not in use, store PET material in a sealed aluminum foil bag to prevent moisture ingress.
Use Desiccants: Include desiccants during storage to absorb any potential moisture, keeping the material dry.
Avoid Direct Sunlight and High Temperatures: Store PET materials in an environment that avoids direct sunlight and high temperatures to prevent material degradation.
Temperature Control: It's best to store PET materials at room temperature; both overheating and excessive cooling can affect the printing performance and quality of the material.
7. Troubleshooting Common Issues
Stringing: If you notice stringing between parts of your print, reduce the printing temperature by 5-10 degrees. Also, adjust the retraction settings—increase retraction distance and speed to pull the filament effectively away from the nozzle during travel moves.
Moisture Problems: If the filament has absorbed moisture, which can caus opping sounds and poor surface quality, dry the filament. Use an oven set at 100-120°C for 4-6 hours. Store the filament in a sealed bag with desiccants to prevent reabsorption of moisture.
8. Annealing
Siraya Tech PET-CF is a robust engineering filament that can be used right off the
spool without annealing.
However, if you need to enhance its hardness, consider annealing it at 90-100°C for 4-6 hours. Be mindful of potential shrinkage during the annealing process.
