It is recommended to dry PETG HF before printing, and it is also advisable to keep it continuously dried during printing and storage to ensure stable print quality and avoid issues such as stringing, bubbling, or poor layer adhesion.
For best results, it is recommended to use a filament dryer such as the SnapDryer during both pre-print drying and continuous printing.
| Build Plate | Recommendation |
|---|---|
| U1 Textured PEI Steel Plate | Recommended |
| U1 Smooth PEI Steel Plate | Glue is required for proper bed adhesion and reliable printing |
| U1 Graphic Effect Steel Plate | Recommended |
| Comparison Dimensions | PETG Basic | PETG HF |
|---|---|---|
| Flowability | Moderate | Higher |
| Recommended Print Speed | 40–80 mm/s | 100–300 mm/s |
| Surface Quality | Good at low speed, noticeable degradation at high speed | Maintains good quality even at high speed |
| Layer Adhesion | Good | More consistent (significant advantage at high speed) |
| Printing Difficulty | Moderate (requires tuning) | More forgiving and stable |
| Mechanical Properties | Standard PETG strength | Improved high-speed printing performance while maintaining strong mechanical properties |
To reduce stringing, you can optimize printing conditions in the following ways:
