Process | T1 [°C] | T2 [°C] | Rotation Speed [rpm] | Dose Rate (g/min) | Filament Appearance |
---|---|---|---|---|---|
1 | 165 | 175 | 40 | 50 | |
2 | 185 | 200 | 80 | 50 | |
3 | 185 | 190 | 80 | 50 | |
4 | 175 | 185 | 50 | 30 |
* For the filament formation stage the S-TPU(PCL)0.9 was selected due to, cytotoxicity results, higher swelling ratio, as well as lower water contact angle than S-TPU(PCL)1.1 sample.
