Additive Manufacturing Technologies for Crash loaded structural Components - AM-Crash

Project summary

Metal-based laser additive manufacturing (LAM) is able to create complex high performance parts. The AM-Crash project will develop this technique for the automotive sector for highly dynamically loaded applications. Therefore, an adaptable LAM concept for different crash-loaded applications in Body-in-White-structures regarding to strength and ductility requirements will be educed. The aim of AM-Crash is to achieve equivalent mechanical properties of LAM components compared to standard deep-drawn parts. This will create significant cost and lead-time benefits using LAM parts for prototype vehicles during car development for crash tests, for small batch series components and for spare parts. The identical structural behavior like deep-drawn sheet metal will be achieved by a multifactorial approach combining a specific LAM processing with suitable post treatment and joining technologies. Numerical simulations to predict final part properties will accompany the entire process chain.
