Additive manufacturing with LMD allows the production of near net-shaped parts. However any slight irregularity in one layer can add up with time and result in component deviations.
At Fraunhofer IPK we developed build-up strategies that result in a constant build process.
We could prove the transferability of build-up strategies for different materials.
These insights allow for a faster strategies development for more geometries, e.g. the connection area of a worn out gas turbine burner.
