Innovative Produktentwicklung durch additive Fertigung

Additive Manufacturing processes are already being used successfully in wide-ranging areas such as the automotive industry, mechanical and plant engineering and medical technology. Due to high flexibility, targeted variation of the machine parameters and the often contactless production, there is a considerable added value compared to conventional processes. A decisive factor in the process chain of additive manufacturing is the design. Components can be newly or differently designed and optimized, for example, with regard to their topology or the integration of functions and effects. For an evaluation of suitability, potentials and requirements must be specified, geometries must be designed and components must be simulated and validated. In addition, a close link between internal company processes, business models and the design are necessary.
