Rapid Prototyping & Prototype Model Makers in Cambridge

Make the first of its kind

Rapid prototyping, To most people, it is a prototype. To you, it is the moment your idea becomes real.
It now has weight, feel and edges. People can hold it, test it, inspect it and judge it.
It is no longer just a concept on a screen.
We make prototypes and limited-run parts with the care and precision this moment deserves.
So you can learn fast, make better decisions and move forward without losing what made the idea worth making.

Foundation

First-of-a-kind meets real world precision

We work between a promising CAD model and a prototype that has to survive testing. Our clients are in medical devices, defence, aerospace, automotive, industrial systems, electronics, robotics and consumer products. Before any machine starts, we agree the process, material and schedule, because the wrong process usually costs more time than it saves. Forty years of model making sits behind those calls. See our full rapid prototyping services.

Confidentiality and Compliance

A first-of-a-kind project exists nowhere else, so confidentiality protocols are standard here. If your organisation needs more, we will set it up: restricted-access workspaces, password-protected file sharing, NDAs for every team member who touches the job, and full audit trails. We work regularly in regulated sectors, including medical and defence, and we plan compliance into the project from the quote stage. Documents such as SOPs, Technical Agreements and Certificates of Conformity can be built into the job if you flag them when you ask for a quote.
