Motivation
With the help of laser powder bed fusion, 3D-multi-material components with an arbitrary material distribution in all three spatial directions can be realized: On the one hand, the porperties in the component can be adjusted voxel-wise, thus resolving conflicts of objectives, and on the other hand, additive manufacturing offers a high degree of design freedom.
Objectives
First, the potential for the production of 3D-multi-material components is identified. Based on this, a demonstrator for laser powder bed fusion using the material combination steel/copper alloy is developed and produced. Finally, the additively produced component willl be manufactured and validated. The PhD project focuses on two main research questions:
- How can contradictory properties be resolved through the targeted use of multimaterials?
- What does a procedure for the integration of thermoelectric effects of highly stressed structural components look like?
