Comparison of SLM, EBM, and BJ in terms of key parameters relevant to hierarchical structure fabrication.
| Parameter | SLM | EBM | Binder Jetting (BJ) |
|---|---|---|---|
| Layer thickness | 20–50 μm | 50–100 μm | 50–200 μm |
| Porosity levels | 1–5% | 2–8% | 10–20% (adjustable) |
| Material anisotropy | High | Low | Moderate (depends on sintering) |
| Resolution of features | High (fine details) | Moderate | Low (requires post-processing) |
| Fatigue life qualitative) | Moderate | High | Low |
