Replacement parts
Snapped clip, worn knob, discontinued bracket. We reverse-engineer it from a photo and make it — often in a tougher material than the original. Fix a part →

What we make
One workshop, six ways to use it
Printed in tough everyday plastic (FDM) or fine-detail resin, cast in stone-like Jesmonite or concrete — whatever the job actually needs.
Custom 3D printing
FDM and resin printing in the right material for the job — PLA to carbon-fibre nylon, resin for models and masters. Printing service →
3D design, no file needed
A sketch on a napkin, a photo and a tape measure — that’s enough. We do the CAD, and you keep the files. Design service →
Casting & homeware
Hand-cast Jesmonite and concrete studio pieces in our own finish recipes — plus silicone mould-making for makers. Casting →
Sculpture & editions
Original pieces and small numbered editions in cold-cast bronze and Jesmonite — certificates included, moulds retired. Sculpture →
For business
Prototypes, jigs, enclosures, props and small production runs — invoiced properly, delivered when promised. Work with us →

A fixed price and an honest timescale — the aim is the same day. If we’re not the right shop for it, we’ll say so.
We design & make it
You approve the design before anything is printed or cast. Bespoke jobs take a small deposit.

Why "Kelvin Forge"
Precision has a unit. It’s named after Glasgow.
The kelvin is the unit the world measures temperature in — named for Lord Kelvin, who did his life’s work a few miles north of our bench, on the river that powered Glasgow’s first mills. His name travels on every datasheet on earth.
That’s the standard we borrowed. Measure properly, make properly, finish properly. Everything that leaves this workshop is test-fitted and checked by the same person whose name is on the quote.
What we won’t do — and why you can trust us more for it:
- No trademarked or licensed designs — no Warhammer, no Disney, no exceptions.
- No items marketed for under-14s without a proper toy-safety route (EN 71).
- No job we can’t do well. If injection moulding or a machinist is the right answer, we’ll tell you.
New studio, open workshop. We launched in 2026 and we’re building our public gallery job by job — see what’s currently on the bench in the workshop log.
