Preparing for Printing
| Drying | Dry at 100-120°C for 4-6 hours |
| Nozzle Diameter | 0.4-1.0mm |
| Nozzle Material | Hardened steel or higher grade |
| Recommended Build Surface | PEI or coat with PVP glue stick |
| Printer requirements | Enclosure (Prevent warping and cracking) |
*Note:
- Only dry if filament shows signs of moisture.
- Drying is not required for the first unpacking unless the vacuum packing becomes damp.
Printing setting
| Nozzle Temperature | 300℃ |
| Build Plate Temperature | 80°C |
| Raft Separation Distance | 0.08-0.12mm |
| Cooling Fan Speed | OFF |
| Print Speed | 30-120mm/s |
| Max Extrusion Volumetric Speed | 20mm/s at 320°C |
| Retraction Distance | 1-3mm |
| Retraction Speed | 1800-3600mm/min |
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. |
| Temperature Control | Store at room temperature; avoid extreme heat or cold. |
Annealing Process
| Key points | Processing |
| Advantages | Increase HDT and hardness. It is not a required step and should only be done as needed. |
| Time | 4 hours |
| Temp | 95°C |
| Process | Dip the parts in white aluminum oxide sand and place in an oven or food dehydrator. |
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 PET-GF in oven set at 100-120°C for 4-6 hours 2. Store the filament in a sealed bag with desiccants |
