Prototype to complete assembly

Where this route may help

• Resin or polymer prototypes to check fit, access and handling.
• Laboratory fixtures, mechanisms and high-tech product housings.
• Multi-process assemblies needing mechanical, electronic or supplier integration.

What determines suitability

• A visual or fit prototype does not demonstrate final material performance. Match each prototype to the question it is intended to answer.
• Document revisions and interfaces so an improvement in one part does not create a conflict elsewhere.
• Repeat manufacture needs a released configuration, process definition and acceptance criteria.

What to include in the first brief

• Intended use and the decision the next prototype must support.
• Critical interfaces, target envelope and available CAD or sketches.
• Expected quantities, finish and operating conditions.
• What needs to be measured, demonstrated or approved before the next step.

Evidence is part of the route

Use a requirement-to-evidence plan, revision log, material and process records, dimensional checks and relevant functional tests. In-house operations and partner operations are identified in the agreed scope.
