Conference Paper
Full-text available
This paper presents the design and fabrication of a lightweight composite concrete slab prototype using 3D printing (3DP) of mineral foams. Conventionally, concrete slabs are standardized monolithic elements that are responsible for a large share of used materials and dead weight in concrete framed buildings. Optimized slab designs require less mat...

3D printing of mineral foams is a novel technology where the changes in material properties during and after fabrication affect the final geometry. These changes need to be quantified with sensing techniques, in order to increase the process robustness for fabricating custom-shaped building components. In this paper, camera tracking and 3D scanning...
Article
Full-text available
Large-scale additive manufacturing for construction has gained momentum during the last two decades as a promising fabrication technology that can save materials, labor, and costs. Although foams are a significant material group in construction and explored in 3D printing (3DP) studies, no comprehensive review about this field exists to date. Conse...

Topology optimization (TO) is a numerical simulation to identify an optimal distribution of solid and void. A more efficient distribution of material means a reduction of natural resources consumption. TO results in branching structures, difficult to manufacture with conventional methods. Advances in additive manufacturing allow the production of c...

This paper presents the design and fabrication of a lightweight composite facade shading panel using 3D printing (3DP) of mineral foams. Albeit their important role in industrial construction practice as insulators and lightweight materials, only little research has been conducted to use foams in 3DP. However, the recent development of highly porou...

This paper introduces the cutting-edge 3D Concrete Printing (3DCP) process which stands at the core of the project Concrete Choreography, a family of nine prefabricated concrete columns. By simultaneously overseeing technological development, computational design and robotic fabrication, an interdisciplinary research team was able to reframe the ch...
Conference Paper

The context of digital fabrication allows architects to reinvestigate material, process and the design decisions they entail to explore novel expression in architecture. This demands a new approach to design thinking, as well as the relevant tools to couple the form of artefacts with the process in which they are made. This paper presents a customi...
Conference Paper
Full-text available
Geometric differentiation is no longer a production setback for industrial grade architectural components. This paper introduces a design and fabrication workflow for non-repetitive large-scale space frame structures composed of custom-manufactured nodes, which exploits the advantages of latest advancements in 3D-printing technology. By integrating...
