Additive Manufacturing by selective laser melting (SLM) in powder bed

  • Highly complex components with function integration
  • Internal conformal cooling channels
  • Weight optimisation due to lattice and honeycomb structures as well as topology-optimised components
  • Simultaneous build-up of different designs
  • Functional prototypes made of series materials

Additive Manufacturing with a 125 x 125 x 200 mm (X / Y / Z) building volume

  • High precision building of 3D parts with a focus diameter of only 35 µm
  • Application-specific fibre laser sources from 200 W as standard to 400 W optional
  • Optimised shield gas volume flow for highest component quality with minimum Argon consumption
  • Open system: Individual adjustment of all machine settings and process parameters as well as unrestricted selection of the material supplier
  • End-to-end competence with integral process understanding from drawing to finished part: DMG MORI Process Chains for pre- and post-processing of additively built parts

rePLUG – The powder module for fast material change

  • Automated powder handling: Integrated powder-recycling for maximum efficiency and highest work-safety due to closed material cycle 
  • One material per rePLUG – Any expansion of the material range due to modular changing system
  • Contamination-free change between different materials in <2 hours
  • High process autonomy due to powerful duo filter system (filter change without process interruption) as well as large powder reservoir (no manual refilling required in the process)
  • Optional: rePLUG RESEARCH The additional powder module, especially developed for the material and process parameter development on the series system
