Buzzword EHLA: You are investigating this Additive Manufacturing process in order to qualify it as a possible tool to develop powder-based alloys especially adapted to AM processes. What is the motivation behind this?
For materials development, in this case powder-based alloy development, it is necessary to be able to selectively vary the chemical composition and the solidification conditions of the material, because this primarily influences its properties. With the EHLA process, we can adjust the chemical composition of the powder material within seconds through local powder feeding, so that a wide variety of materials can be processed quickly for subsequent screening. In addition, the solidification conditions can be varied by process parameters, such as the process speed. Therefore, EHLA fulfills the essential requirements for fast and resource-efficient material development.
…and talking about motivation: What vision do you associate with the development of new materials for Additive Manufacturing?
My vision is to finally exploit the full potential of Additive Manufacturing via customized and improved materials and, hence, to make products even more efficient. For me, this means, for example, improving the sustainability and resource efficiency of additively manufactured components through lightweight applications or longer product lifetimes.
Finally, a question that is also not far away from the topic of motivation: Your answer to the question “Either elevator or stairs” is stairs – sounds sporty?
Yes, at least I endeavor to be…even if I do take the elevator in the morning when I’ve already climbed 80 meters on my bike. But it’s basically true: I prefer to use my own physical strength to get around, regardless of whether I’m participating the Campus or Lousberg Run in Aachen, riding my bike in everyday life, or taking long-distance bike tours on vacation.
