Robotic knitcrete: Computational design and fabrication of a pedestrian bridge using robotic shotcrete on a 3D-Knitted formwork

The research project presented here aims to develop a design-informed manufacturing process for complex concrete shell structures in additive manufacturing and thus overcome limitations of traditional construction methods such as formwork- and labor intensity. To achieve this, an effort was made to merge the two technologies of CNC knitted...

Xpandables: Single-filament Multi-property 3D Printing by Programmable Foaming

We propose a new approach to obtain local property variations in 3D-printed objects using a single-nozzle 3D printer and one filament. We use foaming filaments which expand at different rates due to different temperatures. We present an approach to harness this varying expansion by including parameters of the 3D printing process in the design...

Nano-modification in digital manufacturing of cementitious composites

Remarkable attention from both academia and industry has been attracted to extrusion-based 3D concrete printing (3DCP) during the last decade. Many companies in the Netherlands, e.g., Royal BAM Group, CyBe, Twente Additive Manufacturing, and Bruil, are attempting to implement this technology in practice. 3DCP is the focused digital concrete...

Parametric design strategies: Robotic building in academic architectural research and education

Parametric design strategies employing design-to-robotic-production (D2RP) approaches are relative new in architecture. They require trans-disciplinary research that at Hyperbody, TUD is experimentally tested in academic education and research. This paper presents and discusses trans-disciplinary approaches employing strategies that cross...

Digital technology impacts on the Arnhem transfer hall structural design

The new Transfer Hall in Arnhem is one of the key projects to prepare the Dutch railways for the increased future demands for capacity. UNStudio developed a master plan in 1996 for the station area of which the completion of the Transfer Hall in 2015 will be a final milestone. The Transfer Hall is a merging point of passengers, commercial and...

Cloud Arch: Application of an EPS composite to create an ultra-lightweight long-span sustainable structure

Expanded Polystyrene foam (EPS) is a chemically inert and 100% recyclable material that is lightweight and has a good compression strength per weight ratio; however, its current construction use is mostly limited to insulation or landfill. The key concept of this paper is to develop an EPS composite to create an ultra-lightweight long-span...

Rethinking Prototyping: Scan to Production: Designing with heterogeneous materials

This paper examines how digital scanning techniques can be utilised in the digital fabrication of hybrid materials. It explores how ‘imperfections’ discovered in natural materials can inform unique design solutions. In the first part of this paper, the technical scan-to-production process is explained. Secondly, the paper discusses this new...

An Open-Source Building System with Digitally Fabricated Components: A design- and production process that makes optimal use of the predicted next industrial revolution

With digital fabrication, our hardware is starting to bear greater resemblance to software. This paper explores the potential of processes used in the development of open-source software for the field of Architecture. The developed design process is connected to a building system that provides new insights on constructing with CNC-cut 2D...

Packing Optimization for Digital Fabrication

We present a design-computation method of design-to-production automation and optimization in digital fabrication; an algorithmic process minimizing material use, reducing fabrication time and improving production costs of complex architectural form. Our system compacts structural elements of variable dimensions within fixed-size sheets of stock...

Designing the Negative: An exploration of robotic fabrication for customized concrete formworks

Designing the Negative was the title of a Master Studio that took place at the Institute of Architecture and Media of Graz University of Technology during the summer semester of 2012. Students designed and fabricated prototypes of customized concrete formwork as part of their studio assignment. The studio theme forced students to think about...

Traditional Wood Joint System in Digital Fabrication

Tugite and Shiguchi are traditional architectural techniques of Japan, which connect materials without the use of nails or adhesives. Tugite is a technique to connect materials to augment the lack of length of available materials. Shiguchi is a technique to connect materials at an angle. With a firm basis in this tradition and the craftsmanship...

WoodWeaver: Fabricating curved objects without moulds or glue

design a single free-form curved surface and to fabricate it based on the bending deformation characteristics of the material. The system also indicates an invalid shape; that is, one that will break upon bending deformation. The user can then design a valid shape with this information. We also develop an optimal Dukta pattern that is the...
