Applications

Concept Prototypes

Use an early machined part to review form, fit, handling, and assembly direction before the complete design is fixed.

Engineering overview

Make the first physical build answer a focused question.

A concept prototype helps turn an early CAD model into a physical reference for engineering discussion. The goal is not to make every feature production-ready. It is to identify the interfaces, proportions, and assembly questions that must be resolved before the design advances.

Discuss a concept prototype What to send

Define the first-build question

Start with the decision the prototype needs to support. Form, fit, access, handling, and assembly may each require attention to different features.

Describe the assembly or review activity.
Identify the features that must be physically representative.
List assumptions that the build should confirm or challenge.
Explain how the result will influence the next revision.

Separate fixed and provisional details

Do not apply the same level of control to every early feature. Mark the interfaces that already matter and distinguish them from geometry that is likely to move.

Identify mating holes, locating faces, and envelope limits.
Mark cosmetic surfaces only when appearance is part of the review.
State which dimensions may change after the build.
Avoid adding tight tolerances without a functional reason.

Applications / Manufacturing context

Each build should answer a clear engineering question.

Representative media supports the engineering discussion and does not document a specific customer order.

03 / Project considerations

Prepare the current design package

Send the latest CAD model and any available drawing with a visible revision. The inquiry should explain the material intent, quantity, and review criteria even when some requirements remain open.

Provide overall dimensions and units.
State material preference or the function the material must support.
List the number of versions or parts required.
Identify planned design changes separately from current requirements.

Prepare the prototype RFQ

04 / Project considerations

Capture the iteration

After the build, connect observations to the tested part and revision. A short record of fit and assembly findings makes the next machining request clearer.
