Table 2. 3D Printing Parameters for the Different POMaC/PEGDA Biomaterial Ink Compositions for Ring and “Dog Bone” 3D Printed Pieces.
| UV intensity
and duration |
||||
|---|---|---|---|---|
| biomaterial ink composition | extrusion pressure/PSI | print speed/mm·s–1 | during print | after print |
| 50/50 | 10 | 8 | 15% | N/A |
| 60/40 | 10 | 5 | 15% | N/A |
| 70/30 | 30 | 6 | 0% | 100% for 300 s |
| 80/20 | 45 | 6 | 50% | 100% for 300 s |
| 90/10 | 60 | 8 | 100% | N/A |
| 95/5a | 80 | 4 | 100% for 1200 s per slice | 100% for 1800 s |
| 100/0b | 90 | 4 | 100% for 1200 s per slice | 100% for 1800 s |
a
Printing of 95/5 “dog bone” pieces used these printing parameters, but 20 wt % photoinitiator was required.
b
Printing of 100/0 “dog bone” pieces used these printing parameters, but 20 wt % photoinitiator was required.
