summary In this study, we propose a novel computational system called WoodWeaver for fabricating curved surfaces from conventional materials without using moulds. We use a cutting-based material bending method called Dukta. Our system enables a user to 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 smallest-sized gap pattern necessary to represent a user-designed shape. Given a valid shape, the system generates the optimal pattern and a machine cuts four modules with this pattern. Finally, the user assembles these modules to obtain the desired shape.

title A Process-Centric Approach for Teaching Digital Fabrication
source SIGraDi 2013 [Proceedings of the 17th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Chile - Valparaíso 20 - 22 November 2013, pp. 400 - 404
summary New generation of fabrication machines, such as 3-D printers, do not use “real” materials nor processes generally used in building construction, and so further exacerbate the disconnect between laboratory-based prototyping and full-scale building construction techniques. This research critically reviews the results of a graduate fabrication course from a process-centric standpoint. Students in the course create specification for fabrication and assembly activities through a diagrammatic language that integrates several types of construction knowledge such as design, material properties, machine constraints, and assembly guidelines. This document presents the foundations of the methodology, and discussed the results based on two criteria: Process Modeling and CAD/CAM workflow.

summary This ongoing investigation aims to learn from nature novel material organizations and structural systems in order to develop innovative architectural system. We developed a multidisciplinary approach, using scientific analysis and design research and prototyping. We focus on the study of a “living fossil” fish, whose armor system is so efficient it has remained almost unchanged for millions of years. We investigate its morphological characteristics, its structural properties, the assembly mechanisms and the underlying material properties in order to derive new principles to design new enhanced structural systems. We use micro computerized tomography and scanning electron microscopy to observe microstructures, parametric design to reconstruct the data into digital models and then several 3D printing technologies to prototype systems with high flexibility and adaptive capabilities, proposing new gradual material interfaces and transitions to embed performative capabilities and multifunctional potentials.

summary Hyper-Morphology is an on-going research outlining a bottom-up evolutionary design process based on autonomous cellular building components. The research interfaces critical operational traits of the natural world (Evolutionary Development Biology, Embryology and Cellular Differentiation) with Evolutionary Computational techniques driven design methodologies. In the Hyper-Morphology research, genetic sequences are considered as sets of locally coded relational associations between multiple factors such as the amount of components, material based constraints, and geometric adaptation/degrees of freedom based adaptation abilities etc, which are embedded autonomously within each HyperCell component. Collective intelligence driven decision-making processes are intrinsic to the Hyper-Morphology logic for intelligently operating with autonomous componential systems (akin to swarm systems). This subsequently results in user and activity centric global morphology generation in real-time. Practically, the Hyper-Morphology research focuses on a 24/7 economy loop wherein real-time adaptive spatial usage interfaces with contemporary culture of flexible living within spatial constraints in a rapidly urbanizing world.

title Alloplastic Architecture: The Design of an Interactive Tensegrity Structure
source ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 129-136
summary This paper attempts to document the crucial questions addressed and analyze the decisions made in the design of an interactive structure. One of the main contributions of this paper is to explore how a physical environment can change its shape to accommodate various spatial performances based on the movement of the user’s body. The central focus is on the relationship between materials, form and interactive systems of control.Alloplastic Architecture is a project involving an adaptive tensegrity structure that responds to human movement. The intention is to establish a scenario whereby a dancer can dance with the structure such that it reacts to her presence without any physical contact. Thus, three issues within the design process need to be addressed: what kind of structure might be most appropriate for form transformation (structure), how best to make it adaptive (adaptation) and how to control the movement of the structure (control). Lessons learnt from this project, in terms of its structural adaptability, language of soft form transformation and the technique of controlling the interaction will provide new possibilities for enriching human-environment interactions.

title Overcoming Repetition: Robotic fabrication processes at a large scale
source International Journal of Architectural Computing vol. 11 - no. 3, 285-300
summary In the context of the Future Cities Laboratory (FCL) of ETH Zurich, the Professorship for Architecture and Digital Fabrication of Fabio Gramazio and Matthias Kohler has set up a robotic laboratory to investigate the potentials of non-standard robotic fabrication for high rise constructions in Singapore. The high degree of industrialisation of this dominant building typology implies standardisation, simplification and repetition and accounts for the increasing monotony evident in many Asian metropolises. The aim of this research on material systems for robotic construction is to develop a new and competitive construction method that makes full use of the malleable potential of concrete as a building material. A novel, spatial, robotic "weaving" method of a tensile active material that simultaneously acts as the form defining mould, folds two separate aspects of concrete-reinforcement and formwork-into one single robotic fabrication process (see Figure 1). This in-situ process could permit the fabrication of structurally differentiated, spatially articulated and material efficient buildings.

title FluidScape: Research in Parametric Concrete Formwork

summary Given the piecemeal nature of concrete formwork, the phenomenon of the monolithic result relies on elegant detailing, material choice, and formal continuity. Creating complex form out of concrete poses an intriguing problem, where these disparate constructive elements must be dynamic and flexible. This paper describes the design process from conception to prototyping for a public spray park competition project. The challenges inherent in the proposed forms included subtle reveals and ledges for water to flow down. Achieving the desired finish for the concrete requires a precise, digitally-generated form, particular materials and fabrication sequence. The project design and fabrication gives parametric control to Computer Numerically Controlled (CNC) fabrication tools for an output of fluid form.

summary This paper documents and critically reflects upon the design, development, fabrication, and implementation of three pavilion projects developed during 2013-14. The core investigation of this work is the production of architectural spaces characterized by a quality of enveloping, diffuse, visual and spatial atmospheres. The principal activity of the research is aimed at refining methods for software-based exploration of formal complexities and the subsequent need to control variability and efficiency in fabrication output, using Grasshopper for Rhino to develop customized definitions particular to each specific project scenario. Linking the projects together are issues of scale, resolution of effect, and intent to move from disparate assemblies of structure and skin toward composite, manifold construction techniques that address multiple concerns (gravity, bracing, affect, etc) with a minimum of assembly. A material palette common to the current vernacular of CNC-based projects such as plywood, plastics, and other sheet materials is utilised. This work is invested in extending the possibilities of the architect and architecture as a discipline, extrapolating the workflow from these successive projects to the speculative impact of the work upon emerging possibilities of architectural construction and craft.

title Complex Concrete Constructions – Merging Existing Casting Techniques with Digital Fabrication
source Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 613-622
summary In the course of the 20th century, architectural construction has gone through intense innovation in its material, engineering and design, radically transforming the way buildings were and are conceived. Technological and industrial advances enabled and challenged architects, engineers and constructors to build increasingly complex architectural structures from concrete. Computer-Aided Design and Manufacturing (CAD/CAM) techniques have, more recently, rejuvenated and increased the possibilities of realising ever more complex geometries. Reinforced concrete is often chosen for such structures since almost any shape can be achieve when poured into a formwork. However, designs generated with digital tools tend to have limited relation to the efficient modes of production typically used in contemporary concrete construction. A large gap has emerged between the technology in architectural design and the building industry, so that few efficient solutions exist for the production of geometrically complex structures in concrete. This paper focuses on the capabilities and efficiency of existing casting techniques both with static and dynamic formwork which, when combined with digital fabrication, allow innovative fabrication approaches to be taken. Particular focus is placed on slipforming, an approved and efficient construction technique, which until now is unexplored in conjunction with digital fabrication.

title Custom IFC Material Extension – Extending IFC for Parametric Sustainable Building Design
source Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 13-22
summary The enormous variety of design systems and data formats utilised by the actors in the building design process has been recognised as a significant challenge for information exchange and project management. The introduction of the Industry Foundation Classes (IFC) data standard as a paradigm shift has opened a first time opportunity for smooth data and information exchange over the full range of design related parameters and processes, reaching beyond the classical constructional, economic and safety-related requirements. Moreover, IFC allows for the extension of the standard in further areas, corresponding to the specific design, project or client requirements. These user-driven extensions often close an important gap of the IFC standard and can subsequently be imbedded in new releases of the IFC data standard. This paper is focused on the extension of IFC for the purposes of controlling and managing material use, increasing material efficiency and closing material cycles over the life cycle of a building. Material efficiency is defined by the design scopes of material recyclability, element reusability and waste reduction. The practical implications of the data format extension and design-check performance are examined on the level of the data model and, subsequently, on the level of proprietary Building Information Modelling (BIM) software, based on a pre-defined case.

title Building Elements Re-usability Optimization - Design Decision Support Using a Case-Base of Building Information Models and Semantic Fingerprints
source Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 295-305.
summary The complexity of the requirements on buildings is continuously increasing and thus, often confronting designers with interdisciplinary problems, reaching far beyond the traditional challenges and methods of architecture and engineering. Moreover, designers are often required to take decisions, when most of the information and knowledge is still missing or to be generated. In the context of sustainable building design, the re-usability of building elements and the optimisation for exchangeability is crucial for the achievement of two of the main goals: efficient use of material resources and waste reduction. The scope of this work in progress is describing requirements for case-based decision support in order to optimise building element re-usability, create an analysis of explicit re-usability indicators (e.g. “connection liberation”, “modularity” or “life span collision”) and to identify retrieval strategies. A proposal to support decision making processes by retrieving existing design solutions graph representations as well as the use of building information models are also described.

title Affordable Complexity - 'God's Eye' - Sukkahville 2013
source Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 2, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 169-177
summary The paper presents a novel approach on the design of complex forms by re-formulating the relationships between form, structure, material, fabrication and construction. It is proposed that current design models are supplemented by feedback-enabled frameworks, integrating material properties, fabrication constraints and construction logistics. As such, a series of input parameters based on industry standards, filtered through physical testing and digital simulations, feed a central computational model. The outcome is weighed against a set of objectives towards an optimum design solution which embodies construction logic while ultimately opposing costly inflated ad-hoc solutions. Within the above framework and as part of a broader research conducted at [ARC], this paper illustrates a design methodology implemented at the case study of 'God's Eye', winning entry of Sukkahville 2013 International Design Competition. It is further supported that a high tech, interdisciplinary design process based on efficient material assemblies allows for a complex, yet efficient end result, through low tech affordable construction.

summary 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 sustainable roofing structure by integrating the minimum necessary structural tension layer with a certified fire protection system. The authors present this concept in the following four steps, 1) EPS composite structural specimen test, 2) structural optimisation of the reversed displacement model, 3) discretisation with developable surfaces and 4) CNC hotwire rapid prototyping and assembly in scaled prototypes. The Cloud Arch is an economical, material-efficient, thermally insulated, quickly assembled ultra-lightweight construction that eliminates the need for formworks for long-span structures. It can be applied to many types of column-free spaces, such as in factories, gymnasiums, markets and cafeterias.

summary Over the past decade, there has been an increasing interest in exploring the capacity of built spaces to respond dynamically and adapt to changes in the external and internal environments. Such explorations are technologically and socially motivated, in response to recent technological and cultural developments. Advances in embedded computation, material design, and kinetics on the technological side, and increasing concerns about sustainability, social and urban changes on the cultural side, provide a background for responsive/interactive architectural solutions that have started to emerge. This paper presents an ongoing design research project driven by an interest in adaptive systems in nature and a desire to explore the capacity of built spaces to respond dynamically. The paper underlines architecture’s inseparable link to technology and projects a vision of architecture that, through its capacity to change and adapt, becomes an integrated, responsive, adaptive and productive participant within larger ecologies.

title Adaptive Tectonic Systems: Parametric Modeling and Digital Fabrication of Precast Roofing Assemblies Toward Site-Specific Design Response
source ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 327-336
summary In order to design adaptable systems, the requirements include flexible models to generate a range of alternative configurations, analytical engines to evaluate performance, and well-defined selection criteria to identify suitable options. In most cases, design processes driven by performance concentrate on environmental or structural parameters; fabrication often remains disconnected from the generative process. Nonetheless, as design-to-fabrication methods become more robust, it is possible to extend the digital process to introduce fabrication variables to the definition of the project. The main focus of the research presented in this paper is the development of a digital and material workflow that connects design, structural and climate-specific topics (such as sun lighting and water drainage) toward producing a range of efficient structural and spatial assemblies.A case study serves as the main support for this investigation. Miguel Fisac’s “bones” is a light-weight roof system developed during the 1960’s, which had a very well-calibrated structural, natural-lighting, drainage and construction performance, as well as a highly refined spatial output. The system, despite its intelligence, lacked the flexibility possible today: using digital technologies, it can adapt to a significantly wider range of applications. Using “bones” as a starting point, this research develops a design-to-fabrication workflow that attempts to move forward tools, material systems and processes to enable an adaptable tectonic system.This paper describes the background research, concept, form-finding, construction process, methodology, results and conclusions of the investigation.

summary 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 digital fabrication with parametric tools in a hands-on fashion. Using robotic technology and hot-wire cutting, students worked with the robot’s constraints (size of the robot’s arm, robot’s axis and tool’s restrictions) to design complex curved elements that could serve as formwork (the negative) for cast concrete elements (the positive). The students were asked to design a production strategy for their cast concrete elements as well as the application of said elements in an architectural scheme. The student projects confirmed the value of a pedagogy that takes on research-relevant questions in an interdisciplinary studio setting and engages students in a process that is best described as digital crafting: it simultaneously addressed the conceptual and technical as well as the material and tactile aspects of digital fabrication and design.

title A System for Collaborative Design on Timber Gridshells

summary The bent timber laths of the Sound Bites gridshell create two types of performance space over an area of almost 100 m2. Such postformed gridshells are a wellestablished design solution for creating curved forms from linear elements. Extending principles developed since the 1970s, contemporary digital tools have been utilised to drive a renewed interest in them, primarily through so-called form-finding techniques which connect digital and material models through a simulation of shape under bending loads (Nettlebladt, 2013) and the definition of efficient structural geometry acting under compression loads only (Hernandez et. al., 2012). This paper describes the workflow conceived and implemented for the Sound Bites structure. A central challenge of the research was for such a workflow to allow for the principles of gridshell design to be engaged in parallel to other tight constraints and design drivers. As such it needed to facilitate close collaboration between architectural, engineering and fabrication experts. This workflow was tested in the design and realisation of the full-scale structure within a six-week period. The gridshell design was developed through the manipulation of the shape of two edge profiles and the shell form spanning between these. Architectural and fabrication constraints were met and the workflow allowed for a sufficient level of structural analysis to be fed back to inform the design.

title Tree-Structure Canopy:A Case Study in Design and Fabrication of Complex Steel Structures using Digital Tools
source International Journal of Architectural Computing vol. 11 - no. 1, 87-104
summary This paper describes and reflects on the design and manufacturing process of the Tree-Structure canopy for the WestendGate Tower in Frankfurt upon Main, completed early 2011.The project investigated fabrication and assembly principles of complex steel structures as well as the integration of contemporary computational design, engineering, optimization and simulation techniques in a collaborative design approach. This paper focuses on the notion of modular standardization as opposed to non standard customized components. It also engages with issues relating to digital production tools and their impact on construction cost, material performance and tolerances. In addition it examines the reconfiguration of liability during a planning and construction process, an aspect which can be strongly determined by fabrication companies rather than the architect or designer.This paper is written as a reflection on the complete building process when contemporary digital tools are used from design through to fabrication. It studies both the generation of the steel structure as well the ETFE cushion skin. It reports on a collaborative project, where the main author was responsible for the canopies design, parameterization, digitalization and fabrication, as well as for the dissemination of the outcomes and findings during the design and realization process.As such it represents an example of research through design in a contemporary and evolving field.The canopy received a design award by the Hellenic Architecture Association.

title Frameworks for Computational Design of Textile Micro-Architectures and Material Behavior in Forming Complex Force-Active Structures
source ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 281-292
summary Material behavior can be defined as the confluence of associative rules, contextual pressures and constraints of materialization. In more general terms, it can be parameterized as topologies, forces and materiality. Forming behavior means resolving the intricate matrix of deterministic and indeterministic factors that comprise and interrelate each subset of these material- nherent conditions. This requires a concise design framework which accumulates the confluent behavior through successive and cyclical exchange of multiple design modes, rather than through a single design environment or set of prescribed procedures. This paper unfolds a sequencing of individual methods as part of a larger design framework, described through the development of a series of complex hybrid- structure material morphologies. The “hybrid” nature reflects the integration of multiple force-active structural concepts within a single continuous material system, devising both self-organized yet highly articulated spatial conditions. This leads primarily to the development of what is termed a “textile hybrid” system: an equilibrium state of tensile surfaces and bending-active meshes. The research described in this paper looks to expose the structure of the textile as an indeterministic design parameter, where its architecture can be manipulated as means for exploring and differentiating behavior. This is done through experimentation with weft-knitting technologies, in which the variability of individual knit logics is instrumentalized for simultaneously articulating and structuring form. Such relationships are shown through an installation constructed at the ggggallery in Copenhagen, Denmark.

summary Taking as a starting point the hypotheses that the urban body is a self-adapted ecology made of material and non-material components (Bateson, 1972), relationships between elements are examined in an attempt to destabilize the static division of matter and idea and to inquire into those relationships that determine the structural coupling (Maturana, 2002) between body and environment, as well as the constitution of the body itself. Contemporary technology is used in order to trace these alterations and the urban body is examined as a network configuration. The importance of the methodology adopted by the current research lies in the fact that social and economic factors merge with spatial characteristics, allowing for a visualization and re-interpretation of the urban body mutations based on self-adapted reconfigurations and for a prediction of the structural alterations made possible through the reconfiguration of the synaptic forces between elements.
