Integrated Sensor Technology: The Next Step in Additive Manufacturing

The Fraunhofer Institute for Laser Technology ILT will be presenting the latest research results in additive manufacturing technology at the Fraunhofer joint stand at formnext in Frankfurt am Main from November 7 to 10, 2023. Among other things, the Aachen engineers will be showing additively manufactured sensors that are printed directly onto components and that can provide real-time data for predictive maintenance. A new process makes it possible to seamlessly insert sensors into a component during the additive manufacturing process Laser Powder Bed Fusion (LPBF).

When thin layers are sufficient for heavy mechanical engineering

Researchers at the Fraunhofer Institute for Laser Technology ILT are working with ADMOS Gleitlager GmbH to develop a promising alternative to solid rolling bearings for wind turbines. They aim to use extreme high-speed laser material deposition EHLA to produce low-cost and low-maintenance sliding bearings. This resource-saving and economical process can reduce weight and costs by up to 20 to 30 percent. The research project is being funded by the German Federal Ministry of Education and Research (BMBF) and offers a promising solution to help expand wind power quickly.

What can AI do in laser materials processing?

Automation and zero-defect production are important trends in machine construction. Artificial Intelligence (AI) plays a major role in advancing both of them. Today, it can already detect deviations in process monitoring data and implement quality control in real time. In the future, AI will regulate many more processes and simplify process planning through assistance functions. At the third "AI for Laser Technology Conference" on November 23 and 24, 2023, these and other trends in the application of AI in materials processing will be discussed.
