The construction industry is under growing pressure to adopt sustainable practices and materials to reduce its environmental impact. In order to address these issues, we explore an innovative approach for dredged mud from Lake Neusiedl in Austria, a resource that is both abundant and largely untapped, transforming it into a 3D-printable material fo...

Biobased building materials play a crucial role in reducing the embodied Greenhouse Gas (GHG) emissions of buildings. When quantifying the GHG emissions of biobased materials, the methodological choices made when modelling biogenic carbon in Life Cycle Assessment (LCA) influence the results. To showcase these implications, we applied three differen...

3D printing of ceramics has started gaining traction in architecture over the past decades. However, many existing paste-based extrusion techniques have not yet been adapted or made feasible in ceramics. A notable example is coextrusion, a common approach to extruding multiple materials simultaneously when 3D-printing thermoplastics or concrete. In...

Purpose Bio-based insulation materials are one of the most promising solutions for reducing the environmental impacts of building envelopes. Among these materials, the environmental benefits of mycelium-based materials have merely been investigated, despite their promising technical and thermal properties. In this paper, we perform a first prospect...

This research resulted in the development of a method that can be used for filament-reinforced 3D printing of clay. Currently, clay-based elements are mixed with randomly dispersed fibrous materials in order to increase their tensile strength. The advantages of taking this new approach to create filament-reinforced prints are the increased bridging...

This pictorial confronts the urgent need to shift design practices in response to the past and ongoing destruction of habitat structures and the resulting losses of biodiversity. To do this, it illustrates the first iteration of I.N.S.E.C.T. Wall Twin: an architectural installation that endeavours to support coexistence between local insects, fungi...
Article
Full-text available
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...
Conference Paper
Full-text available
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...
Article
Full-text available
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...
Article
Full-text available
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...
Conference Paper
Full-text available
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...
