Additive manufacturing of 3D-multi-material components for laser powder bed fusion

Jahr:  2020
Förderung:  Leibniz University of Hannover
Supervisor:Prof. Dr.-Ing. Roland Lachmayer 
Co-Supervisor:Dr.-Ing. Paul Christoph Gembarski
Projekt-ID17
Location:Leibniz Universität Hannover, Institut für Produktentwicklung und Gerätebau (IPeG) 

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?
