Additive manufacturing technology has led to a paradigm shift in manufacturing engineering. Thanks to the layer-bylayer generation material is only applied at the area where it is needed. The new manufacturing technology allows degrees of freedom for functional optimization and flexibility not seen before, beyond the limits of conventional manufacturing technology. There is a correspondingly high industrial interest in qualifying the additive manufacturing to a high industrial level.

The high potential of additive manufacturing is opposed to the large variety of unsolved issues. These issues can only be solved in a close collaboration between science and industry. Fraunhofer IWS initiated the project "Additive Manufacturing – Agent-3D" to advance the required collaboration. The consortium with its 60 partners establishes a strong network between industry and research organizations.

Within the framework DRESDEN-concept the scientists, together with partners of the TU Dresden, founded an internationally recognized competence center, in which material and manufacturing solutions for challenging products are interdisciplinarily developed. Presently the scientists focus on research fields such as aerospace, automotive industry, tool making, energy technology and medical engineering. In a rapidly developing high technology field the center offers an excellent networking platform for economy, scientific basic research and application-oriented research.

Our process portfolio includes

  • laser buildup welding with wire and powder
  • selective laser melting
  • electron beam melting
  • 3D printing technology

for metallic and intermetallic materials, polymers, functional materials and multi-material systems. With regard to procedures we offer developments for processes, for system and sensor technologies, and for on-line process diagnostics.

The research work of the center focuses on product chains comprising: component design, finishing and processing steps, repair and recycling. Testing and characterization of material and components produced with additive manufacturing technologies belong to the core competences as well.

Cooperation

For several years, the Fraunhofer IWS Dresden and the IfWW – the Institute of Materials Science at the TU Dresden – have been cooperating in the field of additive manufacturing and thus have been able to implement numerous application-driven projects. The objective of networking with research and industrial partners is to overcome existing technological limitations and to define and establish the framework conditions for standardization, process reliability, quality assurance and so on. To this end, we have available paste-based methods, state-of-the-art powderand nozzle-based laser and electron beam technologies, CNC and robotic systems, as well as computer-aided methods of process control and analysis.
