Wire-based LMD for Repair and AM Applications

© Fraunhofer ILT, Volker Lannert

Is a coaxial wire feeding LMD head suited for repair and AM  applications?


Challenge and Motivation

  • ILT has developed a 3D-capable coaxial wire LMD processing head (prototype)
  • Compared to powder additives, wire additives offer advantages such as: high material efficiency, reduced contamination of the deposited material and machine, fewer health & safety hazards


  • Set-up of wire-based LMD
  • Assessment of wire deposited layers (metallurgical evaluation)
  • Evaluation of economical and technical aspects based on gathered data
