Additive Manufacturing in Construction

Focus Area C

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. This ‘digital/real relationship’ will be addressed by physical demonstration objects with assigned digital twins (digital/real demonstrators).
This focus area provides feedback to the A projects by investigating novel design techniques and structural optimisation (C01, C02) as well as innovative assembling principles for additively manufactured structural elements (C05).
Project C 03 can be considered as a first attempt to integrate extended functions from the area of technical building equipment, building physics, and energy aspects. This research area will be expanded in the following funding periods.
Any information about building information modelling (BIM) will converge in project C04. The central research question of C04 is the investigation of the seamless digitalization in construction, and especially the clarification of the interface between planning and production. In project C04 the information from all the projects of focus area C meshes.

In the second funding period, Christoph Herrmann (TUBS / IWF) will join the project to extend the BIM models with controlled material flow models in order to carry out ecological assessments.
The effects associated with the implementation of innovative AM processes in the construction industry will be addressed (C06). In this context, the feedback with respect to element configuration and dimensions of the additively manufactured large-scale structural elements, and the fact that constructions are always immovable, are of central importance. The questions of whether a higher degree of prefabrication due to AMC is a suitable goal or whether in-situ production will keep being of major importance in construction will be addressed in this project.
Finally, future job profiles for skilled workers as well as technical regulations in the area of AMC will be investigated in project C07. This is important for creating the prerequisites for this new technology to be accepted in the construction industry. AMC creates new job opportunities with significantly higher skill levels than traditional construction jobs. Moreover, for the application of additive manufacturing processes in construction practice, the development of adapted technical standards is of essential importance.
