The agenda

9.00 to 09.30 - Come together
We welcome our guests with coffee and butter pretzels.

09.30 to 09:45 - Introduction of the host
Stefan Merkle from Merkle & Partner

09.45 to 10.15 a.m. - Keynote address
Stefan Merkle from Merkle & Partner

10.30 to 11.00 a.m. - Thermal and mechanical anisotropy in additive manufacturing
Christof Ocker, Josef Tomas and Markus Merkel from Aalen University of Applied Sciences
In powder bed based laser melting, the metal powder is melted locally. Due to high temperature gradients, both thermal and mechanical anisotropy occurs, which leads to residual stresses and distortions in the component. The influence of anisotropy in the component is illustrated by means of examples, and strategies for compensation or reduction are presented.

11.00 to 11:30 a.m. - Process simulation - software tools in comparison
Johannes Maier and Dr. Maik Brehm from Merkle & Partner
Various software tools are available on the market that can map the process of additive manufacturing. In order to keep simulation times within a manageable range, various methodological approaches are used. Results from a numerical benchmark study will be shown and evaluated in comparison to experimental results.

11.30 to 12.00 - Numerical simulations for heat treatment in (indirect) additive manufacturing
Dr. Timm Ohnweiler from Carbolite Gero GmbH & Co. KG
Both direct and indirect additive manufacturing processes require a final heat treatment. In addition to the moulding process (injection moulding, 3-D printing, lithography, etc.) itself, heat treatment is an often underestimated production step to obtain optimal component properties. Based on numerical simulations, a new generation of debinding and sintering systems has been developed. Due to the significantly improved gas flow, the best component qualities can be achieved with increased throughput at the same time.

12.00 to 14.00 - Lunch break

14.00 to 14.30 - Strength assessment of additively manufactured components
Dr. Maik Brehm from Merkle & Partner
As a result of the manufacturing process of additively manufactured components, anisotropies occur with regard to stiffness but also with regard to strength. A method is shown which allows to consider these anisotropies in a FE calculation in the material law and to carry out a stress evaluation.

14.30 to 15.00 - Additive manufacturing for space travel - New possibilities for satellite structures
Dr. Marco Mulser from OHB System AG
The presentation will highlight OHB's approach to the introduction of satellite components using additive manufacturing. The process presented focuses on the interaction between design and structural analysis using topological optimisation. Recently developed components will be presented to illustrate the advantages of the technology compared to conventional solutions. An outlook on material property testing and verification of component properties will round off the presentation.

15.00 to 15.30 - Additively manufactured components make optimised flow possible
Chadi Serhan from Merkle & Partner
Additive manufacturing offers a very good manufacturing possibility to really realise flow-optimised structures. In this lecture, the optimisation of structures with regard to flow-mechanical aspects will be demonstrated by means of examples and the potential of 3D printing compared to conventionally manufactured elements will be shown.

15.30 - 16.00 - Coffee break

16.00 to 16.30 - Concluding discussion of the topics and reflection from practice
Dr. Maik Brehm from Merkle & Partner
