Choosing a Prototyping Method for Medical Devices 

Choose the appropriate prototyping technique based on the device’s complexity, material needs, and stage of development:

1. 3D Printing: Ideal for rapid, low-cost prototypes using plastics, resins, or even biocompatible materials for early-stage testing.

2. CNC Machining: Suitable for high-precision prototypes made from metals or durable plastics, often used for functional testing.

3. Vacuum Casting: Used for small-batch prototypes with high-quality surface finishes, often for user testing or presentations.

4. Injection Molding: Employed for high-fidelity prototypes or pre-production models, mimicking final manufacturing processes.

5. Hybrid Approaches: Combine methods (e.g., 3D printing for housing, CNC for metal components) for complex devices.
