Hardware · `LASERTEC 12 SLM` · verification: source checked

The LASERTEC 12 SLM is a DMG MORI additive manufacturing machine that builds metal parts by selective laser melting in a powder bed. Its work area is 125 mm in X, 125 mm in Y and 200 mm in Z, and it uses a fibre laser of 200 W as standard. The stated focus diameter is 35 µm and layer thicknesses start at 20 µm.

## Specification

| Property | Value |
|---|---|

## Connected

- Manufacturer: [DMG MORI](https://machineschema.com/manufacturer/dmg-mori.md)

## Safety

- Automated powder handling with integrated powder recycling forms a closed material cycle, stated to support work safety.
- The modular rePLUG changing system is stated to allow contamination-free change between different materials.

## Study notes

- Build volume is 125 x 125 x 200 mm in X / Y / Z.
- Focus diameter is 35 µm; minimum layer thickness is 20 µm.
- Fibre laser sources are 200 W as standard and 400 W optional.
- Open system: all machine settings and process parameters can be adjusted and the material supplier can be chosen freely.
- Control uses CELOS with a touchscreen and app-based operation; RDesigner allows CAM programming directly on the machine control.
- HEAT-Calculation precomputes mass distribution and automatically adjusts all laser parameters.
- Camera-based monitoring tools check build-up and coating quality.
- rePLUG is a modular powder module holding one material per module, allowing material change in under 2 hours.
- A duo filter system permits filter changes without interrupting the process, and a large powder reservoir avoids manual refilling during the process.
- Optional rePLUG RESEARCH module is intended for material and process parameter development on the series system.
- Optimised shield gas volume flow is stated to give minimum argon consumption.
- Parts cited for the process include components with internal conformal cooling channels and lattice or honeycomb structures.
