CNC
tight as a drum
3, 4 & 5-axis precision machining across metals and engineering plastics. The gold standard for tight-tolerance functional parts, mating features and critical sealing surfaces, with the full mechanical properties of wrought material.

01 Why use it
the good bits
- The highest dimensional accuracy of any process: tolerances down to ±0.05 mm.
- Full wrought mechanical properties: fully dense, predictable fatigue and fracture.
- Widest material range: almost any metal or engineering plastic that comes in block or bar.
- Zero tooling investment: CAD to production part, directly.
- Surface finish Ra 0.4 to 6.3 Ra off the machine; mirror polish in post.
- Critical for threaded holes, sealing flanges, bearing fits, optical mounts.
02 Ideal volumes
how many?
- 1–1,000 parts: with no tooling, CNC wins economically under 500 to 1,000 units.
- High-tolerance components at any quantity where injection moulding cannot hold spec.
- Bridge production while injection moulding tools are being built.
- Hybrid workflow: CNC is standard finishing on every DMLS component we ship.
