3D Printing Concrete on temporary surfaces: The design and fabrication of a concrete shell structure [PDF]

Automation in Construction, 2018
One of the geometrical restrictions associated with printed paste materials such as concrete, is that material must be self-supporting during printing. In this research paper a new methodology for 3D Printing Concrete onto a temporary freeform surface is presented. This is achieved by setting up a workflow for combining a Flexible Mould developed at TU
