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

  • Highly complex components with function integration
  • Internal close-contoured cooling channels
  • Weight optimisation due to lattice and honeycomb structures as well as topology-optimised components
  • Simultaneous build-up of different designs
  • Shorter product development times by quickly available prototypes made of series materials 

Additive Manufacturing with a 300 x 300 x 350 mm (X / Y / Z) building volume

  • 80% more productivity by new dual laser system  - available as single-laser (600 W) or dual-laser (2x 600 W)
  • High-precision optic module with a 80 µm focus diameter, full overlap of scan fields and active cooling
  • Material independent filtration system with automatic passivation of metal dusts for maximum work safety 
  • 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 the powerful duo-filter system (filter change without process interruption, only LASERTEC 12 SLM / LASERTEC 30 SLM 2nd Gen.) 
  • Optional: rePLUG RESEARCH The additional powder module, especially developed for the material and process parameter development on the series system

Melt Pool Monitoring and Analysis

  • PrintRite3D® system by Sigma Labs, Inc. 
  • In-process quality assurance
  • Detection of changes within the energy density and the thermal signature of the melt pool
  • Classification of defects incl. data visualisation in 3D
  • Less trial-and-error builds - Saving resources and machine run time through early detection
  • Production dashboard – Displaying results of printing processes of different machines
