PROTOTYPE PLANNING
Choose the prototype around the question.
A practical way to define the next design decision before committing to a manufacturing route.
Start with the decision you need to make
A useful prototype answers a specific question. Define whether the next build must establish fit, assembly access, stiffness, thermal behaviour, flow or a manufacturing method. One prototype may not represent every property of the final product.
Inspection fixtures and lightweight parts
Record the mounting interfaces, working envelope and intended load before removing material. Compare net CAD volume using the same method for every revision. Keep print supports, waste and measured part mass as separate quantities. The C14 optical inspection fixture study applies this approach to four mounting holes and a central insert; generative design is underway and measured results are still to come.
Multi-material assemblies
Identify the mating surfaces, fasteners, tolerances and sequence of assembly. Select each material for the characteristic being checked. A polymer fit model, a machined interface and a fabricated frame can answer different questions within one programme. Agree how supplier outputs will be inspected before final integration. Explore prototype-to-assembly work.
Repair, restore or remake?
Start with the original material, service history, damage and the surfaces that must be recovered. DED and CSAM are specialist partner routes whose suitability requires a review of the actual component, material and operating conditions. Trials, finishing and inspection may be needed before committing to a restoration route. Compare the evidence and total work with replacement manufacture. DED feasibility · CSAM feasibility.
Composite and polymer prototypes
For the partner Markforged service, describe the working environment, loading direction, critical interfaces and the property being evaluated. DPM and the partner can then review the printer, matrix material, reinforcement and inspection approach together. A material’s name alone does not establish suitability or certification for a finished part.
Bring these inputs to a project review
- A non-confidential sketch, description or existing drawing reference.
- Intended use, critical interfaces and the question the prototype must answer.
- Approximate quantity, target date and available design information.
- Any required inspection, traceability, regulatory or customer acceptance criteria.
We will respond as soon as possible, but within 48 hours.
