Rapid Mechanical Prototyping in Neuchâtel

Need a functional prototype quickly? Louis Wiedmann SA produces your prototypes by CNC machining directly in the final material — not 3D-printed plastic, but real metal or high-performance polymer parts, ready for testing under real conditions.

Our Prototyping Process

• Drawing reception — 2D files (DXF, PDF) or 3D files (STEP, IGES, SolidWorks)
• Feasibility analysis — tolerance check, material selection, quotation
• CAM programming — optimised toolpath for your part
• CNC machining — milling and/or turning as required
• Quality control — dimensional inspection, surface finish check
• Delivery — short lead times, from a few working days

Why CNC Prototyping?

Unlike 3D printing, CNC prototype machining offers decisive advantages:

• Part in the final material — same mechanical properties as production
• Superior precision — tolerances of +/- 0.005 mm
• Excellent surface finish — no visible layers or striations
• Immediate functional testing — assembly, strength, fit
• Seamless transition to small batch production — same program, same machine

Industries Served

We produce prototypes for watchmaking (cases, movement components), micro-electronics (heatsinks, sensor housings), medical and pharmaceutical (instruments, tooling), aerospace (structural components, fasteners) and scientific research (experimental parts, measurement instruments).
