Where This TPU Is Used
- Flexible 3D printing filaments for FDM/FFF printers
- Prototyping of gaskets, grips, flexible housings and shoe parts
- Low-volume customized components and cushioning structures
Typical Grades
| Grade | Hardness | Melt Flow / Viscosity | Key Performance | Filament Diameter | Typical Use |
|---|---|---|---|---|---|
| TPU-3D 85A FX | 85A | Medium flow | Very flexible, good layer bonding, soft touch | 1.75 mm / 2.85 mm | Soft prototypes, gaskets, flexible shells |
| TPU-3D 90A GP | 90A | Balanced flow | Easy filament extrusion, better feeding & dimensional stability | 1.75 mm | General-purpose flexible filaments |
| TPU-3D 95A ST | 95A | Higher flow | Stiffer feel, improved overhangs & printing speed | 1.75 mm / 2.85 mm | Functional parts, brackets, fixtures |
Note: Flow index and hardness can be tuned to suit filament line design and target printer settings (nozzle size, speed, direct/Bowden drive).
Key Advantages
- Stable melt flow for round, consistent filament diameter
- Good layer bonding and surface finish on FDM/FFF printers
- Balance of flexibility vs. printability for 85A–95A range
- Suitable for 1.75 mm and 2.85 mm flexible filament products
Processing & Recommendations
- Filament extrusion: drying 80 °C × 2–3 h；melt 190–210 °C（by grade & line speed）
- Use precise diameter control（laser gauge） and chilled water/air cooling
- Recommend smooth drive rollers and correct spooling tension to avoid deformation
- End user printing: typical 210–240 °C nozzle, slow printing speed & reduced retraction (For end-user reference only)
