Metal-based Laser Additive Manufacturing (LAM) technologies are capable of producing high performance parts with tremendous geometric complexity. The AM crash project will further develop this technology for the automotive sector for highly dynamic loaded applications. For this purpose, an adaptive 3D manufacturing concept for various crash-loaded applications in body structures (BIW) with regard to strength and ductility requirements is being developed, with the aim of achieving equivalent mechanical properties of LAM components compared to standard deep-drawn parts. The identical structural behavior of LAM components and deep-drawn sheets is achieved by a multifactorial approach that combines specific LAM processing with suitable aftertreatment and joining / integration technologies. In this project, Simufact will extend the simulation capabilities available in the product Simufact Additive with a validated prototype which allows to predict the effects of the exposure strategy or a subsequent local laser heat post-treatment on the resulting material properties.. The objective of Simufacts work in this project is to create a simulation solution with which suitable exposure parameters can be determined in advance to the actual build-up process.
The AM-Crash project was recommended for funding by the M-era.NET network from the EU's Horizon 2020 research program on materials for additive manufacturing. The German project partners Salzgitter Mannesmann Forschung GmbH, Chemnitz University of Technology, EDAG Engineering GmbH and Simufact are funded by the Federal Ministry of Education and Research (BMBF) through the project promoter PTKA, the Polish partners Wroclaw University of Science and Technology and Wadim Plast Sp. O. O. by their national funding agency NCBR.
