Aluminum 6061 is the top choice for CNC rapid prototyping due to its fast machining, low cost, and good representation of production intent. Prototypes can be delivered in as fast as 3 business days.
| Parameter | Value |
|---|---|
| Achievable Tolerances | ±0.01 mm (prototype standard) |
| Surface Finish | Ra 1.6-3.2 μm (as-machined) |
| Cutting Speed | 200-400 m/min |
| Feed Rate | 0.05-0.15 mm/tooth |
| Tooling Recommendations | Standard carbide end mills. No special tooling needed. |
