Design office and 3D printing workshop

Custom-designed jigs, tooling and parts, even without a 3D file

A broken part, a sketch, a paper drawing? That is enough. We model the part, approve it with you, then make it: inspection gauges, fixtures, foundry patterns, moulds, replacement parts, prototypes.

Pièces de prototype imprimées en 3D pour un robot de préparation de plats cuisinés

No 3D file? No problem

Most of the requests we receive start without a file. Our design office works from whatever you have to hand and produces the 3D model of the part: that is 3D part design, and it is included in the quote.

An existing part, even a broken one: we measure it from your photos and dimensions
A paper drawing or a dimensioned sketch, even hand-drawn
A description of its function: what the part has to hold, guide or protect

Example: three photos of a cracked housing, laid next to a steel rule, are enough. We redraw the part, reinforce the area that failed and send a 3D view for approval before printing.

Inspection gauges and fixtures: what 3D printing changes

A custom inspection gauge or fixture machined from solid is expensive and takes weeks. 3D-printed, it is delivered in a few days, matches the shape of the part exactly and weighs a fraction of metal tooling.

Inspection gauges

Check in one move that a part conforms: outline, hole positions, flatness of an edge.

Fixtures and holding jigs

Hold a part during machining, bonding, welding or assembly, always in the same position.

Drilling and cutting jigs

Transfer a dimension without measuring, with bushes or guides placed exactly where they need to be.

Prototypes, foundry patterns, moulds and jigs

Before committing significant spend to manufacturing a final part, a printed part lets you see it, fit it and approve it in its real environment. We make prototypes, foundry patterns, moulds and jigs, from small precision parts to large formats.

Large-format jigs to check a part's footprint before it is manufactured
Scale parts for sand moulds
Resin moulds with very fine detail
Test prototypes to validate a machine before the production run

Example: in the nuclear sector, a bearing jig 80 cm wide by 60 cm high, designed to hold a drive shaft, made it possible to validate the part in its environment before launching its manufacture.

Example: resin moulds for fishing lures, reproducing the scales and the smallest surface details.

Reproducing a broken or unobtainable part

A plastic part you can't find, a spare no longer made, a supplier gone out of business: often all that is left is a broken part and a machine at a standstill. We remake the plastic part identically, or better than the original when the failure came from a design flaw.

Clips, gears, handles, covers, sensor brackets, parts for older equipment: if the part fits in our machines and its function suits a printable material, we can reproduce it. If not, we tell you at the quote stage.

Example: a plastic gearbox gear, no longer available from the manufacturer, is redrawn from the worn part and printed in PA12 nylon, which resists wear better than the original material.

Functional prototype before the production run

Before committing to a mould or a production run, a custom prototype lets you check fit, assembly and mechanical strength on a real part. A prototype takes a few days and costs a fraction of a mistake discovered after tooling.

The approved prototype becomes the reference file: the same part can then be produced in a small batch, in the same material, without redoing anything.

Technical materials: PETG-CF, PA12, resins…

The material is chosen according to the part's load, temperature and environment, from more than 50 materials. We advise you at the quote stage; here are a few of the most requested for tooling and functional parts.

Carbon-fibre PETG

Rigid, stable and light. The usual choice for jigs, fixtures and workshop brackets.

PA12 nylon

Resistant to impact, wear and many chemicals. For gears, clips and moving parts.

Engineering resins

Smooth surfaces and fine detail, in rigid, impact-resistant, high-temperature or transparent grades.

And many more, up to high-performance polymers for extreme conditions: see PEEK, PEKK, ULTEM and PPSU. All our materials are listed on the Technologies page.

How it works

You describe

Drawing, photo, sketch or file, with the part's function and the quantity. An NDA can be signed before you send anything.
Quote and e-signature online

A detailed quote, usually within 24 hours, design included, which you sign online in a few clicks.
Online payment

A secure payment link is sent to you by e-mail.
Prototype and approval

You approve the 3D model, then a first sample if the part calls for it.
Production and delivery

One-off or batch, inspected and shipped with a tracking number.

Every stage is tracked automatically: from the quote onwards, each of our e-mails carries a personal tracking link. You can see where your part stands and find your documents at any time, without creating an account.

What to send us

Photos of the part from several angles with a ruler alongside, or a drawing, even hand-drawn
Its function and constraints: load, temperature, contact with chemicals
The quantity you need
Your deadline

Typical lead times and budget (design included)

Every part is priced on its geometry and material: our rates are competitive and calculated as tightly as possible, design included. The quote usually arrives within 24 hours.
