Benefits of Rapid Prototyping

1. Early Design Validation Catch problems before investing in expensive tooling:

• Verify fit with other components
• Test ergonomic factors
• Validate aesthetic direction
• Confirm assembly sequence

2. Stakeholder Feedback Get buy-in various, customers, and team members:

 ✗ Sketch on paper ✓ Physical prototype → 10x more effective communication

3. Iteration Speed Test multiple variations quickly:

• Design A vs. Design B
• Different material options
• Various finish treatments

4. Reduced Risk Identify issues early means:

• Lower tooling modification costs
• Fewer production delays
• Better final product quality

Prototyping for Injection Molding While prototypes can be made various:

Material Selection Choose prototype materials that represent production materials: Production MaterialPrototype OptionABSABS-like resinPPPP-like resinPCPC-like resinNylonNylon SLS

Design Testing Prototypes help validate:

• Undercut locations
• Draft angle adequacy
• Ejector pin placement
• Gate visibility
