This research was carried out to develop a novel composite material consisting of a thread reinforcement and a clay matrix, as well as to develop a method of shaping this material into hollow spatial structures. Ceramic elements in the building industry are currently created by applying extruding, pressing and casting methods. The approach of spray...
This research proposes a new controlled shaping method of thin-walled clay elements. A clay layer is applied to a carrier material, in order to use the shrinkage behaviour of clay as a shaping agent. This shaping process utilises the change of ratio of adhesion forces through the bond of a planar carrier material with a wet clay layer on its surfac...
By means of appropriate computer software, freeform surfaces (also called freeforms) can be digitally generated, discretized, structurally optimized and prepared for CNC fabrication. Designers and architects are highly attracted by freeform surfaces, because their digital generation seems very simple. However, the design of freeform surfaces in fac...
The embodied carbon emissions from building materials and construction are today responsible for 38% of annual GHG emissions in the current global environment. If we are to reach the European energy plan with net-zero emissions by 2050, now is the time to rethink our construction principles, as well as building elements and materials. One of the po...
The subject of this research is growing mycelium-based composites and exploring their basic material properties. Since the building industry is responsible for a large amount of annual CO2 emissions, rethinking building materials is an important task for future practices. Using such composites is a carbon-neutral strategy that offers alternatives t...
In this paper we will demonstrate a digital workflow that includes a living material such as mycelium and makes the creation of structural designs possible. Our interdisciplinary research combines digital manufacturing with the use of mycelial growth, which enables fibre connections on a microscopic scale. We developed a structure that uses materia...

In this research we demonstrate that a digital workflow and a living material such as mycelium, make the creation of smart structural designs possible. Ceramics industries are not as technically advanced in terms of digital fabrication, as the concrete or steel industries are. At the same time, bio-based materials that use growth as a manufacturing...
In this paper, we will demonstrate a new method of using knitted meshes to act as a formwork and to reinforce thin and hollow spatial clay structures. Currently, ceramic elements in the building industry are formed using extruding, pressing, or casting methods. This new approach can increase the usability of digitally fabricated lightweight element...

By means of appropriate computer software, freeform surfaces (also called freeforms) can be digitally generated, discretized, structurally optimized and prepared for CNC fabrication. Designers and architects are highly attracted by freeform surfaces, because their digital generation seems very simple. However, the design of freeform surfaces in fact remains an immense challenge. Many aspects of the complex interrelations between geometry, construction, materiality and structural properties have not been properly addressed in current geometrical research. Most notably, more research is required to study the limitations that arise from different materials and the links between the freeform geometry and finding efficient ways to develop the formwork, starting with fabrication, ranging over logistics up to assembly. The complexity of designing an appropriate surface and/or formwork for freeforms occurs at all scales, ranging from furniture to objects in the building scale. The formwork for a general freeform object consists of discretized custom molds, which are often milled, very expensive and only used for one particular form. Additionally, every different building material like concrete, glass, ceramic, carbon or wood demands a specific building strategy, including a tailored geometrical approach. Goals/contribution: The major scientific contributions in this project will be: (1) The development of new geometrical definitions of freeform surfaces based on their material and functional properties in order to develop strategies to find cost-efficient freeform structures with stay-inplace and/or reusable formwork; (2) the enrichment of computational geometrical models with material and structural information. The methodology will be research through design studies and experiments. Based on an in-depth study of the fundamentals of surface geometry, we will create a series of novel models at different scales with the aim to elaborate the different properties based on the respective material. We will use moldable, linear and planar materials. This will be conducted in four phases: (1) experimentation, (2) testing and measurement, (3) computation and parameterization, and (4) post processing and optimization.
