2nd place for poster at 3rd DGM conference on materials and additive manufacturing

From May 11 to 13, 2022, the 3rd Symposium on Materials and Additive Manufacturing of the DGM - German Society for Materials Science took place. The ifw Jena was able to take second place with its poster on discontinuities in additively manufactured components.

At the DGM conference, which took place in Dresden and was broadcast online, ifw Jena presented a poster on the project EDaB - Influence on the fatigue strength of additive components. In the project, flaws in the form of pores are deliberately introduced into additively manufactured components, which are then subjected to dynamic tensile tests to check the influence of the flaws on the component.

The poster showed initial results of the investigations. For example, it has already been demonstrated that the strength of an additively manufactured component is only affected above a certain pore size. Likewise, the poster shows that the location of the pores in the component plays a major role. The closer the pores are to the edge of the component, the more they reduce the strength of the component.

With his investigations in the project, our colleague Christoph Weidig is building on findings from the QuaPla project, in which the influence of discontinuities in additively manufactured components has already been investigated in static tensile tests. The research results from both projects are intended to contribute to the development of guidelines for the quality assurance of additively manufactured components and to provide companies with characteristic values for their production.

Congratulations to Christoph Weidig for the 2nd place for his poster!

The project is funded by the German Federal Ministry of Economics and Climate Protection in the INNO-KOM program.
