Validating designs before production tooling
| Method | Time | Accuracy | Best For |
|---|---|---|---|
| 3D Print (SLA/SLS) | 1-3 days | +-0.1mm | Form/fit testing |
| CNC Prototype | 3-7 days | +-0.05mm | Functional test, production material |
| Vacuum Casting | 5-10 days | +-0.15mm | 10-30 samples |
| Soft Tooling (Al) | 3-4 wk | +-0.08mm | 500-5000 parts |
| Bridge Tooling | 6-8 wk | +-0.05mm | 10K-100K parts |
