Copper rapid prototyping is used for thermal and electrical validation where conductivity testing requires the actual production material.
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.02 mm |
| Surface Finish | Ra 0.8-1.6 μm |
| Cutting Speed | 100-300 m/min |
| Feed Rate | 0.05-0.15 mm/tooth |
| Tooling Recommendations | Sharp uncoated carbide or PCD. |
Sharp tooling essential for good finish
Challenging to machine — allow extra lead time
