Comparison of the geometry, density and porosity of the printed scaffolds with the CAD model
| Strut thickness | Pore width | Density | Porosity | |
|---|---|---|---|---|
| Printed PLA | 412.9 ± 21.4 (μm) | 739.5 ± 13.6 (μm) | 0.426 ± 0.006 (g cm3) | 65.68 ± 0.454 (%) |
| CAD model | 400 (μm) | 800 (μm) | 0.385 (g cm3) | 68.99 (%) |
| Mean printing error (%) | 3.23 | − 7.56 | 10.66 (%) | − 4.79 (%) |
| Printing error range (%) | − 3.5–8.25 | (− 9.9)–(− 4.9) | 8.3–16.14 | (− 7.3)–(− 3.8) |
