(author), Roussel, Nicolas (author), Perrot, Arnaud (author), Sonebi, Mohammed (author), Wolfs, Rob (author), Bos, Freek (author), Lowke, Dirk (author), Grunewald, S. (author)Digital fabrication with cementitious materials is a rapidly growing field of research in which the evolution of strength during the various processes, such as 3D printing, is the key controlling parameter. The strength evolves over multiple orders of magnitude during the process, and thus, it is essential to properly characterize the strength...book chapter 2022

3D Printing Concrete on temporary surfaces: The design and fabrication of a concrete shell structureBorg Costanzi, C. (author), Ahmed, Z. Y. (author), Schipper, H.R. (author), Bos, F. (author), Knaack, U. (author), Wolfs, R.J.H. (author)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...journal article 2018

Schipper, H.R. (author), Borg Costanzi, C. (author), Bos, Freek (author), Ahmed, Z (author), Wolfs, R. (author)It is no secret that there have been some great advances in the realm of concrete additive manufacturing. However, one of the major drawbacks of this fabrication technique is that the elements must be self-supporting during printing. While most other additive manufacturing materials can overcome this by using a secondary printed support...working paper 2017
