It is necessary to dry TPU 95A HF before printing. TPU is highly moisture-sensitive, and absorbed moisture can lead to issues such as stringing, bubbling, and inconsistent extrusion.
For optimal print quality, it is also necessary to keep the filament continuously dried during printing and storage.
For best results, it is recommended to use a filament dryer such as the SnapDryer throughout both pre-print drying and the printing process.
| 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 | Not Recommended |
| Comparison Dimensions | TPU Basic | TPU 95A HF |
|---|---|---|
| Flowability | Lower (soft & sticky) | Higher (easier extrusion) |
| Recommended Print Speed | 20–40 mm/s | 60–150 mm/s |
| Feeding Stability | Prone to slipping/jamming | More stable |
| Stringing | Pronounced | Improved |
| Retraction Response | Poor (typical for soft materials) | More controllable |
| Printing Difficulty | High (especially for beginners) | Significantly reduced |
| Equipment Requirement | High (direct drive recommended) | More compatible and user-friendly |
| Elastic Performance | Standard TPU elasticity | Similar (smoother in some cases) |
To reduce stringing effectively, you can optimize the following:
To reduce the risk of nozzle clogging, you can optimize the following:
