Production technology

The power of Additive Manufacturing

The Mobile Smart Factory uses a hybrid machine from METROM for component production and parts repair service. Based on a patented parallel kinematics concept the machine combines a WAAM module with a milling and drilling unit.

Operating principle
  • Pre-processing: The processing strategy and its toolpath are programed individually, using a CAD software
  • Production: Layer-by-layer structure of the part using arc welding / Fusing of a metal wire with the aid of a welding torch forms the blank
  • Post processing: After the build job, parts are generally post-processed by machining
WAAM characteristics and benefits
  • High build rates: deposition rates of up to 4kg/h are possible
  • Low cost: Simple process and cheap raw material
  • Suitable for repair operations: damaged parts can be repaired on site
  • Large parts possible: the part size is almost unlimited
  • Stable process and well established: process is well-controlled; industry-specific standards and best practices exist
  • Wide material availability: off the shelf welding wires can be used
  • High-quality parts: parts show high density and good mechanical properties

The automated building with integrated finishing processes is based on CAD data of the component created in the operating container. With this solution, the system operator only has to set up and position the workpiece. The welding and machining process runs as an NC program based on pre-qualified parameters.
