Choose the decision before the detail
An appearance model, a fit model and a working prototype can require different levels of detail. Share the decision you need to make next so the quote can focus on the useful work. A product idea does not need every internal feature resolved before a first shape can be discussed.
AI-assisted tools can help explore alternative forms from the brief. We can then discuss which option is worth developing into a dimensioned model and a print. Record the selection criteria so the next revision has a clear purpose.
Keep a record of each revision
Label the version you test and note what changed. Photos of the fit, marked-up dimensions and observations from the trial are more useful than a general request to make the model better. Send the result back with the question for the next print.
A successful prototype does not automatically establish that the design is ready for every production method or intended use. Tell us where the project is heading so prototype decisions can be reviewed in that context before you invest in the next stage.
Questions about product prototypes
Can you start from a rough idea?
Yes. Explain the problem, show any relevant references and identify the dimensions you already know. We will agree the initial design scope rather than treating a rough sketch as a finished specification.
Can I compare more than one version?
Ask for the variants you want considered. The quote can separate design work, the number of printed versions and any subsequent revision so you can choose the appropriate first step.
