summary	The research presented in this paper revolves around the experimental development of the morpho-structural potential of folded architectural structures made of wood. The aims are to develop an innovative system for timber used in sustainable construction and to increase the inventory of wood architectural tectonics. Laminated timber panels associated with "digital production line" approach have opened up new perspectives for the building industry in creating prefabricated wooden structures. This article provides a characterization of the digital chain associated to the development of non-standard folded structures which consist of wood panels by way of a full-scale experimental pavilion. The purpose is the study of architectural design process from parametric modeling (through CNC machining) and assembly operations to production. Towards the completion of the pavilion, a number of analytical experiments have been performed.

title	Gradient Transparency: Marine Animals As a Source of Inspiration. - Exploring Material Bio-Mimicry through the Latest 3D Printing Technology in Architectural surfaces

summary	Digital fabrication technologies are changing rapidly the way we design, as any other tool would affect the way we produce space. Multi layered 3D printing is already allowing architects, designers and engineers to experiment with new design processes and new ways of production. At the same time, little research has being done in the way gradient transparency (through multiple layered surfaces) can affect the design process through computation; a field that deserves further investigation. The focus of this paper is to explore bio-inspired material finding design processes while combining biology, architecture and material science. We explore performance driven design possibilities through a study of marine animals -and specifically cephalopods- where opacity between skin layers is controlled through color pigments - while black pigments are called melanophores - which is often used as a type of camouflage. We propose a computation model that follows the logic of gradient transparency through pigments to fit complex “host surfaces”. We define a “host” surface as a basic geometry on which the pigments are computed. This study provides the methodology for the design of biomimetic surfaces with gradient transparency, using controlled and computated sub geometries analogous to the melanophores pigments. We finally propose Pigment Skin, a computational design model as an example to materialize this study.

summary	This paper presents the production and development of an adaptive robotically fabricated ber composite compression shell with pneumatic formwork as a case study for investigating a generative behavioral design model and an adaptive, online mode of production. The project builds off of previous research at the University of Stuttgart on lightweight ber composite structures which attempts to reduce the necessary formwork for fabrication while simultaneously incorporating structural, material and fabrication logics into an integrative computational design tool. This paper discusses the design development and fabrication work ow of the project, as well a set of strategies which were developed for online robotic programming in response to live sensor data.

title	Form Follows Flow: A Material-Driven Computational Workflow for Digital Fabrication of Large-Scale Hierarchically Structured Objects
doi	https://doi.org/10.52842/conf.acadia.2015.185
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 185-193
summary	In the natural world, biological matter is structured through growth and adaptation, resulting in hierarchically structured forms with tunable material computation. Conventional digital design tools and processes, by contrast, prioritize shape over matter, lacking integration between modeling, analysis, and fabrication. We present a novel computational environment and workflow for the design and additive manufacturing of large-scale hierarchically structured objects. The system, composed by custom multi-barrel deposition attached to robotic positioning, integrates material properties, fabrication constraints and environmental forces to design and construct full-scale architectural components. Such components are physically form-found by digitally extruding natural polymers with functionally graded mechanical and optical properties informed by desired functionality and executed through flow-based fabrication. In this approach, properties such as viscosity, velocity, and pressure embed information in two-dimensional printing patterns and induce three-dimensional shape formation of the fabricated part. As a result, the workflow associates physical material and fabrication constraints to virtual design tools for modeling and analysis, challenging traditional design workflows and prioritizing flow over form.

title	A Collaborative Approach to Digital Fabrication:A Case Study for the Design and Production of Concrete ‘Pop-up’ Structures
source	International Journal of Architectural Computing vol. 13 - no. 2, 195-216
summary	The research presented in this paper utilizes industrial robotic arms and new material technologies to model and explore a prototypical workflow for on-site robotic collaboration based on feedback loops. This workflow will ultimately allow for the construction of customized, free-form, on-site concrete structures without the need for complex formwork. The paper starts with an explanation of the relevance of collaborative robotics through history in the industry and in architecture. An argument is put forward for the need to move towards the development of collaborative processes based on feedback loops amongst the designer, the robot and the material, where they all inform each other continuously. This kind of process, with different degrees of autonomy and agency for each actor, is necessary for on-site deployment of robots. A test scenario is described using an innovative material named concrete canvas that exhibits hybrid soft fabric and rigid thin-shell tectonics. This research project illustrates the benefits of integrating information-embedded materials, masscustomization and feedback loops. Geometry scanning, parametric perforation pattern control, computational analysis and simulation, and robotic fabrication were integrated within a digital fabrication deployment scenario. The paper concludes with a detailed report of research findings and an outline for future work.

title	Adaptive Polymer Based BIPV Skin

summary	This study focuses on developing three-dimensional solar panels, as an alternative to traditional flat Photovoltaic (PV) surfaces in Building Integrated Photovoltaic (BIPV). We propose to increase the energy efficiency of buildings by using the entire envelope for energy production as well as by increasing the efficiency of solar energy output in orientations which were traditionally considered as non-ideal. The panels are constructed from Polycarbonate with integrated flexible photovoltaic film, solar paint or dye. The methodology included digital algorithm-based tools for achieving optimized variable three-dimensional surfaces according to local orientation and location, computational climatic simulations and comparative field tests. In addition, the structural, mechanical and thermal properties of the integration between flexible PV sheets and hard plastic curved panels were studied. Interim results demonstrate a potential improvement of 50-80% in energy production per building unit resulting from geometric variations per-se. The dependence of energy production by surface geometry was revealed and an optimized method for solar material distribution on the surface was proposed. A parametric digital tool for automatic generation of optimized three-dimensional panels was developed together with a database and material models of the optimized panels system.

title	Generative Processes in Tower Design: Simultaneous Integration of Tower Subsystems Through Biomimetic Analogies
doi	https://doi.org/10.52842/conf.acadia.2015.173
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 173-184
summary	The research presented in the paper formulates part of the methodological approach of a recently completed PhD thesis. The principle aim of the thesis is to achieve simultaneous integration of tower subsystems which can coherently adapt to their internal and external context during the initial phases of the design process. In this framework, the tower subsystems are grouped as the structural system, floor system, vertical circulation system, facade system, and environmental system. The paper focuses on the implementation of the specific biomimetic analogies towards the integration of tower subsystems through computationally generated dynamic systems. The biomimetic analogies are the mechanical and organizational properties of branched constructions, the mechanical properties of the bamboo stem, and the micro-structure of the porcupine quill/ hedgehog spine. Each biomimetic analogy is described in relation to the design domain. Methods of employing the mathematical and geometrical principles of the biomimetic analogies during design explorations are elaborated. Outcomes of the design output are outlined and discussed with a concentration on achieving tower subsystem integration, differentiation, and co-adaptation properties.

title	Transient Thermal Exchange and Developmental Form for Tactile Surfaces
doi	https://doi.org/10.52842/conf.acadia.2015.431
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 431-441
summary	The idea of an emergent or generative form based on repeating rules of development borrowed from the field of developmental biology has provided fertile ground for inspiration for architectural theory and computational design. With simple constraints developed iteratively, complex geometry and form generation can be distilled down to a list of developmental rules or functions in order to deterministically generate form. The ideas and illustrations of naturalists on organic form and developmental biology leading back to the turn of the 20th c., such as the work of D'arcy Wentworth Thompson and Ernst Haeckel, have inspired architects from Louis Sullivan all the way to contemporary generative design. This study revisits this design tradition of biomimetic geometries based on deterministic rules for the iterative development of forms based on biological analogs and models for growth. A series of semi-regular compound patterns were developed using parametric modeling and iterative rules. These geometries were then applied to surface topologies as a decorative tactile embellishment resulting in complex thermodynamic conditions. A series of physical prototypes where then developed with different high-relief patterns and pattern densities. Positive prototype geometries were then produced using stereolithography for casting plaster molds for the production molding of finished ceramic pieces for thermal analysis using digital thermography. By studying the performance of these complex geometries as physical prototypes under controlled experimentation, high-relief surfaces and the resulting thermodynamic conditions can be understood not just qualitative experience, but also quantitatively through measured performance metrics and innovative tools for analytical analysis.

summary	This paper describes and reflects upon a computational de- sign and digital fabrication research project that was developed and implemented over 2014-2015, with subsequent development continu- ing for applications at present. The aim of the research was to develop methods of modelling, analysis, and fabrication that facilitate integra- tive approaches to architectural design and construction. In this con- text, the development of material prototypes, digital simulations, and parametric frameworks were pursued in parallel in order to inform and reform successive iterations throughout the process, leading to a re- fined workflow for engineering, production, and speculation upon fu- ture directions of the work.

title	Generative Design for Folded Timber Structures
doi	https://doi.org/10.52842/conf.caadria.2015.673
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 673-682
summary	Folding structures belong to the group of lightweight structural systems, which often consist of polygonal elements like triangles or quadrangles. Folding structures whose construction is made out of cross-laminated timber (CLT) panels represent an innovative step in the timber industry, which has many advantages. CLT panels can be used simultaneously as supporting elements and as finishing building envelopes. There are many prefabrication possibilities, high efficient material consumption, low production and assembly costs, and it has environmental advantages over conventional materials used for folding structure like concrete, metal or glass. CLT folding structures are not sufficiently explored. One of the reasons may lie in the fact of limited design possibilities, which includes the specificity of CLT capacity. Another reason is maybe the inability to use standard wooden connectors to transfer the forces along the thin linear edges where the panels are supported. The aim of this paper is to present design possibilities through parametric modelling using the characteristics of CLT. Using the example of a wooden theatre stage we will present results of our research.

title	Articulated Timber Ground, Making Pavilion as Pedagogy

summary	Designing and making a pavilion within a studio setting has been undertaken by various educators and researchers as a valuable pedagogy in the past 10 years. It aims to construct a collaborative environment that allows students to develop an integrated approach to learning; through association, teamwork and creative collaboration. Usually the tacit knowledge applied and acquired through making, and the knowledge of design strategy and analysis are separated in the way they are taught; it is often difficult to integrate these within the same coursework which often leads to students using digital software and fabrication tools as problem solving devices. This paper looks at an integrated approach to learning computational design and digital fabrication through the making of a pavilion by a Master level design studio. The paper discusses the pedagogy of making through creative collaboration and integrated workflow. It focuses on the use of digital and physical prototypes as devices to stimulate an oscillating dialogue between problem solving and puzzle making; a counterpoint for students to develop and search for new knowledge in order to create personalised learning experience. The paper concludes with an examination on the limits of digital prototype when interfaced with physical environment.

summary	This paper presents a 3D Concrete Printing (3DCP) experiment at the full scale of virtualarchitectural bodies developed through a computational technique based on the use of Cellular Automata (CA). The theoretical concept behind this technique is the decoding of errors in form generation and the invention of a process that would recreate the errors as a response to optimization (Adilenidou 2015). The generative design process established a family of structural and formal elements whose proliferation is guided through sets of differential grids (multi-grids) leading to the build-up of large span structures and edifices, for example, a cathedral. This tooling system is capable of producing, with specific inputs, a large number of outcomes in different scales. However, the resulting virtual surfaces could be considered as "unprintable" either due to their need of extra support or due to the presence of many cavities in the surface topology. The above characteristics could be categorized as errors, malfunctions, or undesired details in the geometry of a form that would need to be eliminated to prepare it for printing. This research project attempts to transform these "fabrication imprecisions" through new 3DCP techniques into factors of robustness of the resulting structure. The process includes the elimination of the detail / "errors" of the surface and their later reinsertion as structural folds that would strengthen the assembly. Through this process, the tangible outputs achieved fulfill design and functional requirements without compromising their structural integrity due to the manufacturing constraints.

title	Towards A Motion Grammar for Robotic Stereotomy

summary	This paper presents progress towards the definition of a motion grammar for robotic stereotomy. It describes a vocabulary of motions able to generate complex forms by cutting, slicing, and/or carving 3-D blocks of material using a robotic arm and a custom made cutting tool. While shape grammars usually deal with graphical descriptions of designs, a motion grammar seeks to address the 3-D harmonic movements of machine, tool, and material substrate choreographically, suggesting motion as a generative vehicle of exploration in both designing and making. Several models and prototypes are presented and discussed.

summary	With an exponential increase in the possibilities of computation and computer-controlled fabrication, high density information is becoming a reality in digital design and architecture. However, construction methods and industrial fabrication processes have not yet been reshaped to accommodate the recent changes in those disciplines. Although it is possible to build up complex simulations with millions of particles, the simulation is often disconnected from the actual fabrication process. Our research proposes a bridge between both stages, where one drives the other, producing a smooth transition from design to production. A particle in the digital domain becomes a drop of material in the construction method.The architect's medium of expression has become much more than a representational tool in the last century, and more recently it has evolved even beyond a series of rules to drive from design to production. The design system is the instruction itself; embedding structure, material and tectonics and gets delivered to the very end of the construction chain, where it gets materialised. The research showcased in this paper investigates tectonic systems associated with large scale 3D printing and additive manufacturing methods, inheriting both material properties and fabrication constraints at all stages from design to production. Computational models and custom design software packages are designed and developed as strategies to organise material in space in response to specific structural and logistical input.Although the research has developed a wide spectrum of 3D printing methods, this paper focuses only on two of the most recent projects, where different material and computational logics were investigated. The first, titled Filamentrics, intends to develop free-form space frames, overcoming their homogeneity by introducing robotic plastic extrusion. Through the use of custom made extruders a vast range of high resolution prototypes were developed, evolving the design process towards the fabrication of precise structures that can be materialised using additive manufacturing but without the use of a layered 3D printing method. Instead, material limitations were studied and embedded in custom algorithms that allow depositing material in the air for internal connectivity. The final result is a 3x2x2.5m structure that demonstrates the viability of this construction method for being implemented in more industrial scenarios.While Filamentrics is reshaping the way we could design and build light weight structures, the second project Microstrata aims to establish new construction methods for compression based materials. A layering 3D printing method combines both the deposition of the binder and the distribution of an interconnected network of capillaries. These capillaries are organised following structural principles, configuring a series of channels which are left empty within the mass. In a second stage aluminium is cast in this hollow space to build a continuous tension reinforcement.

summary	Performance-based architecture has predominately been influenced by computational advances in simulating complex organizations. The advent of 3D printing, however, has introduced a new approach to generate complex forms, which is redirecting focus from shape-centric design to material design, namely, innovative structures and properties generated by the process itself. This article investigated the multiscale approach potential to design using extrusion-based 3D printing techniques that offer novel geometric organizations that conform to desired performance. It was found that 3D printed toolpaths adapted to extrusion-based systems render an anisotropic behavior to the architectural object that is best optimized by designing tessellated surfaces as the primary structural shape from which small-scale periodic surfaces can be embedded within a larger geometric system.

summary	This paper presents a computationally based methodology arising from the application of weaving techniques for the design and construction of an experimental architectural system, Weaving Enclosure. The research explores the close correspondence between material properties and assembly systems found in the traditional craft of weaving, studied through analytical and laboratory tests, and then implemented through computational design and digital fabrication. The workflow for the generation of specific geometries related to the elastic nature of the material results in the design and fabrication of a self- standing interior partition with digitally conceived patterns, tuned parametrically to provide structural and screening performance.

Different patterns have been studied through a design workflow based on parametric software and the use of Particle Spring systems to support the form-finding process of bending-active auxetic structures. An advanced understanding of their bending capacity is explored with the use of variable infill patterns informed by structural analysis. Furthermore, principles for the design and fabrication of auxetic gridshells are discussed.

summary	Thermal Form, is architecture that does work. Or, it is the application of energy as information to architectural geometry, with the express purpose of using the resistance of structure against an opposing thermodynamic force, in order to manipulate and direct flows that exist in both the interior and along the exterior of a building. By examining the relationship between surface configuration, surface area and type of energy transfer occurring - with a focus on the mechanism of transfer - thermal form strategies can be used to further optimize existing building typologies and environmental control system strategies, or, perform a more radical detouring of the atmosphere of a building.

summary	C-LITH is the reconsideration of the architectural building unit through the exploration of new composite techniques and materials. Our project develops individual compo- nents that exploit the strength, lightness, and variability possible with carbon ber laments when paired with computation, digital fabrication, and hand assembly. Traditionally, architectural units made of brick or concrete are small and multiple, heavy, dif cult to vary, and are much better in compression than tension. Using carbon ber laments to create variable units allows for larger individual units that can vary in both shape and structural performance as needed. Our units, developed through winding pre-preg carbon ber tow around disposable molds, bene t structurally from the quasi-isotropic properties that are developed through the winding patterns. The specific structural capacities of the units remain to be understood through further testing and analysis, which falls outside the scope of this current research. At this junction, structural capacities have been determined empirically, i.e. will it stand? Most importantly, as a formal study, our units address the use of carbon ber at the scale of architectural production. A majority of the effort involved in materializing C-LITH was the development of a two-fold prototypical manufacturing process that produces the components and assembly. For this we invented a method to quickly and cheaply construct variable cardboard molds that could withstand the wound casting and baking steps, but could also be easily weakened through water immersion to be removed. For the assembly we developed a rigid dummy-jig system to hold the joint plates in position with a high level of precision but could also incrementally absorb the adjustment errors unavoidable in hand assembly systems. Using a simple pin connection the resultant structures can be easily disassembled for transportation and reassembly elsewhere.
