From prototype to production
By Fabrup · Updated September 8, 2026
A working prototype is progress. Reproducing it consistently at the planned cost and with measurable quality requires further preparation.
Choose the right prototype for the question
An appearance model checks size and ergonomics. A functional prototype tests a mechanism. A sample made using the final process helps assess material, finish and performance. A 3D-printed part may behave differently from an injection-moulded part: interpret results according to what was actually made.
Adapt the design to the manufacturing process
Manufacturability reviews consider thickness, assembly, access to fasteners and necessary tolerances. Unnecessarily tight tolerances can increase cost, while imprecise interfaces can prevent assembly. Specialists work through these choices with the factory while preserving the intended function.
Define the tooling investment
Before commissioning a mould or jig, agree ownership, storage location, maintenance and modification terms. Quotes should separate tooling from parts and specify included trials. Document rights to drawings and files needed for continuity of production.
Approve a pilot run before scaling
A pilot run tests the documentation against the actual process: assembly, checks, repeatability, packaging and traceability. Agree acceptance criteria before it is made. Document corrections and revalidate where needed. Visual inspection does not replace suitable performance testing or regulatory assessment.
Your production decision checkpoint
Before deciding, ask for the list of open issues, specification revision, approved sample references and planned checks. For each unresolved issue, identify the owner and the evidence needed. A delivery schedule is not technical approval.
Move forward with Fabrup
You can bring an existing prototype even if we did not design it. We review available files, completed checks and open questions to coordinate the next steps with technical specialists and manufacturers. Iterations, timing and responsibilities are agreed in the scope.
A product or production issue to discuss?
Tell Jérémy what you are making, where the project stands and what needs attention. A first conversation helps define whether a focused coordination assignment makes sense.
