What is additive manufacturing in construction?
Flexibility of form and in the timing of production
3D printing is a synonym for additive manufacturing, in which a material is built up layer by layer to produce a component. In construction, this means a manipulator moves the print head along a required trajectory, applying the material layer by layer. These layers then create the structure. The material used is typically mortar or concrete.
Transferring 3D printing technology into construction practice more broadly requires an interdisciplinary approach involving construction management, construction machinery and construction materials.
Construction Future Lab offers a large-scale testing ground for investigation of various issues as the technology is further developed.
The real potential of 3D concrete printing
Accelerated construction work and increased labor productivity
Elimination of shuttering and scaffolding
Reduction of construction process to a few key operations
Reduction in technically complex manual work

Construction process: The digital process chain
In order to produce a building that has been planned, additive construction processes require a printing strategy. A continuous process chain is needed, from the building model through machine control of the printing process to the digital documentation model, in order to ensure automated construction methods are cost-effective and correctly executed.
One challenge is the automated processing of the data required to control the concrete 3D printer, taking into account the printing material and machine, as there are currently no standards for digital process flows. In addition, the lack of measurement technology makes it difficult to collect data to document the execution phase.
A closed data chain—from planning to execution and back—enables execution quality to be increased and printing scenarios to be reproducible.
