Focus area A “Materials and Processes”
Focus area A “Materials and Processes” centres on the investigation of basic principles for the development from scratch of unique AMC processes for concrete, steel, and timber. As mentioned above, the innovation potential of the proposal is based primarily on the merging of material and process developments produced in interdisciplinary research teams.
Focus Area B “Computational Modelling and Control”
The experimentally driven investigations of focus area A ‘Materials and Processes‘ are enhanced by the corresponding projects of focus area B ‘Computational Modelling and Control’. All AM processes will be developed by taking into account assigned digital feedback obtained by computational modelling and process control.
Focus area C “Design and Construction”
Focus area C “Design and Construction” addresses the most important subjects related to the implementation of additive manufacturing in the process chain of design and construction. The interaction between digital models and physical objects forms the methodical relationship within TRR 277 and connects the focus areas A and C.
