Systematic analysis of additive process chains

The complete AM process chain is analysed in depth, in order to quantitatively record cause-and-effect relationships between design and construction methodology, data preparation, production parameters and post-processing steps and to evaluate their influence on the resulting quality of the components.

Special attention is paid to the process chain consisting of AM, particle blasting, vibratory grinding and plasma electrolytic polishing. These post-processing steps are systematically analysed with regard to their interactions, process limits and their respective contribution to surface functionality. The focus is particularly on the influences of relevant process parameters - such as medium, processing time, component geometry and process-specific settings - on roughness, microstructure and edge zone properties.

The aim is to develop a process chain that is as short, robust and resource-efficient as possible through the targeted combination and, if necessary, reduction of individual process steps. This should be able to reproducibly fulfil defined surface requirements for metallic components while minimising time, energy and costs and increasing process reliability.

Methodical further development of Design for Additive Manufacturing (DfAM)

The DfAM methods, which systematically utilise geometric and functional design freedom, are being further developed and validated in order to reduce process-induced restrictions, minimise support structures and increase the manufacturing economy and structural performance of additively manufactured components.
