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.

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.
