Selecting the Right Manufacturing Method
Selecting the Right Manufacturing Method
For this prototype housing with complex geometries, several manufacturing methods were considered:
3D Printing (Metal): Could produce the complex shape but lacked precision for optical mounting features and required significant post-processing.
Traditional Machining: Required multiple setups, increasing error risk and lead time.
5-Axis CNC Turning/Milling: Enabled complete machining in a single setup, maintaining critical tolerances while efficiently producing both rotational and prismatic features.
