Metal / DMLS
Direct Metal Laser Sintering
For metal additive we operate a qualified partner network for DMLS/SLM in AlSi10Mg, 316L and 17-4 PH. Every metal program is engineer-reviewed for orientation, supports, stress relief and post-machining.
How Metal / DMLS works
- 01
A laser fuses metal powder layer by layer in an inert atmosphere.
- 02
Supports anchor the part against thermal stress.
- 03
Parts are stress-relieved, cut from the plate, and supports removed.
- 04
Critical surfaces are optionally CNC-finished.
Strengths
- True metal parts
- Complex internal channels
- Consolidated assemblies
- High strength
Limitations
- Engineering review required
- Higher cost
- Surface needs machining for precision fits
Design rules for Metal / DMLS
Full guidance in the interactive design guide.
| Minimum wall (unsupported) | 0.5 mm |

- Every metal order includes a manufacturability review — no instant pricing.
- Plan 0.5–1.0 mm machining stock on critical interfaces.
- Stress-relief and support strategy are engineered per part.
