Technology Cluster "Laser"

The technology cluster "Laser" is divided into four sub-clusters:

  • Selective Laser Melting (SLM)
  • Laser Cladding
  • Process Monitoring
  • Laser Ablation

As an overall goal, the technology cluster »Laser« aims to develop methods to adapt machining strategies, independent of working material, geometry and function, for SLM and Laser Cladding.

For SLM, this goal shall be pursued by observing the complete manufacturing chain from component design via adapted processing strategies and process parameters all the way to identifying specific mechanical values and post-processing.

Laser Cladding

In the sector of Laser Cladding, a technology processor shall be developed which encompasses three modules and binds them together:

  • A data base to manage process parameters and processing strategies dependent upon working material and geometry.
  • A model module to clad turbine blade geometries using laser-based processes.
  • Experimental investigations to adapt process guidance during laser cladding.

In close cooperation with the sub-cluster Process Monitoring, an online and offline process monitoring system shall be developed to adapt laser cladding processes.

Furthermore, laser ablation shall be investigated and qualified as a new manufacturing approach. For this, partners shall focus on investigating basic issues. By using short-pulse and ultrashort-pulse lasers, engineers shall examine possible ablation rates, properties of ablated surfaces and the mechanical properties of laser-ablated working materials.
