Cellular Concrete Column

For the research project, Additive Manufacturing by the Use of Lightweight Concrete at the Chair of Timber Structures and Building Construction at the Technical University Munich a concept was commissioned which should showcase the capabilities of the 3D-Printer developed by the researchers.

For most of history, essential building elements in architecture are defined by three dimensions: length, height, and width. Cause for this is mainly the limited abilities of the design and manufacturing tools. This column concept represents an investigation of the impact on those elements by the informed use of Computational Design and Additive Manufacturing. In comparison to regular columns, which consist of a solid mass, the cellular column consist of a heterogeneous lattice, that differentiates its density according to the load within the column - less material in areas of less load.

The function of a vertical load-bearing element, however, remains the same, but it is overall constructive performance as well as its visual stimulus increased. Hence, constructive and visual aesthetics form an inseparable unit.
