summary	This article explains the evolution towards the subject of digital fabrication of thin shell structures, searching for the computational design techniques which allow to implement biological pattern mechanisms for efficient fabrication procedures. The method produces data sets in order to analyse and evaluate parallel alternatives of branching topologies, segmentation patterns, material usage, weight and deflection values as a user learning process. The importance here is given to the selection of the appropriate attributes, referring to which specific geometric characteristics of the parametric model are affecting each other and with what impact. The outcomes are utilized to train an Artificial Neural Network to predict new building information based on new combinations of desired parameters so that the user can decide and adjust the design based on the new information.

summary	The emerging paradigm of Industry 4.0 is rapidly expanding in the AEC sector, where emergent technologies are offering new possibilities. The use of collaborative robots is enabling processes of advanced fabrication, where humans and robots coexist and collaborate towards the co-creation of new building processes. This paper focuses on setting a conceptual framework and a computational workflow for the design and assembly of a novel type of engineered wood structures. The aim is advancing timber construction through complex tectonic configurations, which are informed by logics of robotic assembly, topology and material optimization, and combinatorial design. Starting from the conceptualization of robotic layered manufacturing for timber structures, this work presents the development of a digital twin applied to the voxel-based design of complex timber structures.

title	Meeting in the middle: Hybrid clay three-dimensional fabrication processes for bio-reef structures
source	International Journal of Architectural Computing vol. 17 - no. 2, 148-165
summary	Despite the relative accessibility of clay, its low cost and reputation as a robust and sustainable building material, clay three-dimensional printing remains an under-utilized digital fabrication technique in the production of architectural artefacts. Given this, numerous research projects have sought to extend the viability of clay three-dimensional digital fabrication by streamlining and automating workflows through computational methods and robotic technologies in ways that afford agency to the digital and machinic processes over human bodily skill. Three-dimensional printed clay has also gained prominence as a resilient material well suited to the design and fabrication of artificial reef and habitat- enhancing seawall structures for coastal marine environments depleted and disrupted by human activity, climate change and pollution. Still, these projects face similar challenges when three-dimensional printing complex forms from the highly plastic and somewhat unpredictable feed material of clay. In response, this article outlines a research project that seeks to improve the translation of complex geometries into physical clay artefacts through additive three- dimensional printing processes by drawing on the notion of digital craft and giving focus to human–machine interaction as a collaborative practice. Through the case study of the 1:1 scale fabrication of a computationally generated bio-reef structure using clay as a feed material and a readily available Delta Potterbot XLS-2 ceramic printer, the research project documents how, by exploiting the human ability to intuitively handle clay and adapt, and the machine’s ability to work efficiently and with precision, humans and machines can fabricate together . With the urgent need to develop more sustainable building practices and materials, this research contributes valuable knowledge of hybrid fabrication processes towards extending the accessibility and viability of clay three-dimensional printing as a resilient material and fabrication system.

summary	In the context of data-driven culture, built space still maintains low responsiveness and adaptability. Part of this reality lies in the low resolution of live information we have about the behavior and condition of surfaces and materials. This research addresses this issue by exploring the development of a deformation-sensing composite membrane material system following a bottom-up approach and combining various technologies toward solving related technical issues—exploring conductivity properties of graphene and maximizing utilization within an architecture-related proof-of-concept scenario and a workflow including design, fabrication, and application methodology. Introduced simulation of intended deformation helps optimize the pattern of graphene nanoplatelets (GNP) to maximize membrane sensitivity to a specific deformation type while minimizing material usage. Research explores various substrate materials and graphene incorporation methods with initial geometric exploration. Finally, research introduces data collection and machine learning techniques to train recognition of certain types of deformation (single point touch) on resistance changes. The final prototype demonstrates stable and symmetric readings of resistance in a static state and, after training, exhibits an 88% prediction accuracy of membrane shape on a labeled sample data-set through a pre-trained neural network. The proposed framework consisting of a simulation based, graphene-capturing fabrication method on stretchable surfaces, and includes initial exploration in neural network training shape detection, which combined, demonstrate an advanced approach to embedding intelligence.

title	Compliant Laminar Assemblies

summary	This paper presents an innovative approach to the design and fabrication of three-dimensional objects from single-piece flat sheets, inspired by the origami technique of twist-closing. While in origami twist-closing is merely used to stabilize a cylindrical or spherical structure, ensuring it maintains its shape, this research investigates the potential of twist-closing as a multi-functional mechanism that also activates and controls the transformation of a planar surface into a predesigned three-dimensional form. This exploration is directed towards an intended application to stiff and brittle sheet materials that are difficult to shape through other processes. The methods we have developed draw mainly upon principles of lattice kirigami and laminar reciprocal structures. These are reflected in a workflow that integrates digital form-generation and fabrication-rationalization techniques to reference and apply these principles at every stage. Significant capabilities of the developed methodology include: (1) achievement of pseudo-double-curvature with brittle, stiff sheet materials; (2) stabilization in a 3D end-state as a frameless self-contained single-element laminar reciprocal structure—essentially a compliant mechanism; and (3) an ability to pre-encode 3D assembly constraints in a 2D cutout pattern, which guides a moldless fabrication process. The paper reviews the precedent geometric techniques and principles that comprise this method of 3D surface fabrication and describes a sample deployment of the method as applied to the design of laminar modules made of high-pressure laminate (HPL).

summary	This research showcases the integrated design process and development of an ultra-light-weight, composite dome structure as a case study for the investigation of high-performance, long-span, fibre-reinforced-polymer (FRP) based building systems. Particular emphasis is given to the exploration of design strategies and the exposure of multidirectional flows of information across different fields under the premise of going beyond preliminary investigations on a demonstrator level, towards full scale architectural applications. Building upon previous research in the realm of lightweight fiber composites conducted at the University of Stuttgart, novel design strategies and fabrication methods are discussed. Based on the design and development of the Buga Fibre Pavilion for the Heilbronn Bundesgartenschau 2019, previously prototypically tested processes are further developed and implemented at a larger scale which attempt to reduce the necessary formwork to a minimum while achieving a flexible and scalable building system.

summary	This paper lays out a fabrication and simulation method for an adaptable and reusable moulding system for the production of fibre reinforced concrete elements. This research leverages soft robots and their computational controllability as means of a composite material and as such the base of a controlled and adaptable moulding system. This paper describes the development of this programmable material towards a functioning system for casting processes with fibre glass reinforced concrete. The controllable material allows to deploy target shapes and to eliminate supplementary falsework and the customized production of moulds for doubly-curved concrete elements. It also lays out a feedback method, which serves as adjustment tool of the simulation to the physical behaviour of the material as well as simulation method for target based geometries.

doi	https://doi.org/10.52842/conf.acadia.2019.332
summary	The ongoing research presented in this paper lies on the threshold between computational design and digital fabrication with a strong focus on emergent techniques for environmental design. The main hypothesis is, that with an increasing granularity of thermal comfort - observing a trend towards more heterogeneous indoor microclimates – new design challenges arise. Architectural fabrics will be required to communicate indoor climate conditions to the inhabitants, to maintain high levels of thermal comfort locally but specifically. This research investigates a novel generative design methodology, which links computational fluid dynamics simulations, robotic fabrication and material-inert performances. The resulting environmentally active panels respond to climatic conditions and by this communicate parameters of thermal comfort, such as temperature, airflow, and humidity, to the inhabitants. This paper presents a digital design workflow, a prototype for a thermochromic panel, and speculates on potential development. Communicating invisible parameters of thermal comfort to users is a crucial requirement when designing large continuous indoor volumes, when blurring the dichotomous duality of inside and outside and when designing highly porous architecture.

title	Implementing Augmented Reality for the Holographic Assembly of a Modular Shading Device
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 149-158

summary	The development of innovative digital design and fabrication tools for material processing and manufacturing of complex and non-standard forms, apart from their advantages, have brought a number of challenges. These might be related to the effectiveness and sustainable potential of implementation associated with environmental, cost and time-related parameters, particularly in cases of large number of elements construction and complex assembly. Augmented Reality (AR) is an emerging technology with great potential for implementation in the construction industry, since it can enhance the real world with additional digital information, and thus, can assist towards manufacture and assemble of these particular systems. This study presents an AR methodology for assembling a modular shading device and discusses the advantages and disadvantages that this application can bring to the Architecture, Engineering and Construction (AEC) industry by taking into account precision and construction time issues based on the handling of the process by skilled and unskilled users/workers. Our aim is to investigate the potential implementation of AR in the assembly, and consequently, in the construction process as a whole. Also, this study aims at exploring existing constraints of the technology and suggests ways of improvement.

title	Semi-flexible Additive Manufacturing Materials for Modularization Purposes - A modular assembly proposal for a foam edge-based spatial framework
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 1, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 463-470
doi	https://doi.org/10.52842/conf.ecaade.2019.1.463
summary	This paper introduces a series of design and fabrication tests directed towards the use of bendable 3D printing materials in order to simplify a foam bubble-based geometry as a frame structure for modular assembly. The aspiration to reference a spittlebug's bubble cocoon in nature for a light installation in the urban context was integrated into a computational workflow conditioning light-weight, material-, and cost savings along with assembly-simplicity. Firstly, before elaborating on the project motivation and background in foam structures and applications of 3D-printed thermoplastic polyurethane (TPU) material, this paper describes the physical nature of bubble foams in its relevant aspects. Subsequently this is implemented into the parametric design process for an optimized foam structure with Grasshopper clarifying the need for flexible materials to enhance modular feasibility. Following, the additive manufacturing iterations of the digitally designed node components with TPU are presented and evaluated. Finally, after the test assembly of both components is depicted, this paper assesses the divergence between natural foams and the case study structure with respect to self-organizing behavior.

doi	https://doi.org/10.52842/conf.ecaade.2019.1.729
summary	This paper presents intermediate results of an experimental research directed towards development of a method that uses additive manufacturing technology as a generative agent in architectural design process. The primary technique is to variate speed of material deposition of a 3D printer in order to produce undetermined textural effects. These effects demonstrate local variation of material distribution, which is treated as a consequence of interaction between machining parameters and material properties. Current stage of inquiry is concerned with studying the impact of these textural artefacts on structure. Experiments demonstrate that manipulating distribution of matter locally results in more optimal structural performance, it solves printability issues of overhanging geometry without the need for additional supports and provides variation to the surface. The research suggests aesthetic and structural benefits of applying the developed method for mass-customized fabrication. It questions the linear thinking that is predominant in the field of 3D printing and provides an approach that articulates interaction between digital and material logics as it directs the formation of an object that is informed by both.

summary	Advanced manufacturing and robotic fabrication for the housing construction industry is mainly focused on the use of industrial robots in the pre-fabrication stage. Yet to be fully developed is the use on-site of collaborative robots, able to work cooperatively with humans in a range of construction trades. Our study focuses on the trade of carpentry in small-to-medium size enterprises in the Australian construction industry, seeking to understand and identify opportunities in the current workflows of carpenters for the role of collaborative robots. Prior to presenting solutions for this problem, we first developed a novel methodology for the capture and analysis of the body movements of carpenters, resulting in a suite of visual resources to aid us in thinking through where, what, and how a collaborative robot could participate in the carpentry task. We report on the challenges involved, and outline how the results of applying this methodology will inform the next stage of our research.

doi	https://doi.org/10.52842/conf.ecaade.2019.2.201
summary	Collaborative Robots, or Cobots, bring new possibilities for human-machine interaction within the fabrication process, allowing each actor to contribute with their specific capabilities. However creative interaction brings unexpected changes, obstacles, complexities and non-linearities which are encountered in real time and cannot be predicted in advance. This paper presents an experimental methodology for robotic path planning using Machine Learning. The focus of this methodology is obstacle avoidance. A neural network is deployed, providing a relationship between the robot's pose and its surroundings, thus allowing for motion planning and obstacle avoidance, directly integrated within the design environment. The method is demonstrated through a series of case-studies. The method combines haptic teaching with machine learning to create a task specific dataset, giving the robot the ability to adapt to obstacles without being explicitly programmed at every instruction. This opens the door to shifting to robotic applications for construction in unstructured environments, where adapting to the singularities of the workspace, its occupants and activities presents an important computational hurdle today.

title	Steps towards AI augmented parametric modeling systems for supporting design exploration
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 1, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 81-90
doi	https://doi.org/10.52842/conf.ecaade.2019.1.081
summary	Dataflow parametric modeling environments have become popular as exploratory tools due to them allowing the variational exploration of a design by controlling the parameters of its parametric model schema. However, the nature of these systems requires designers to prematurely commit to a structure and hierarchy of geometric relationships, which makes them inflexible when it comes to design exploration that requires topological changes to the parametric modeling graph. This paper is a first step towards augmenting parametric modeling systems via the use of machine learning for assisting the user towards topological exploration. In particular, this paper describes an approach where Long Short-Term Memory recurrent neural networks, trained on a data set of parametric modeling graphs, are used as generative systems for suggesting alternative dataflow graph paths to the parametric model under development.

doi	https://doi.org/10.52842/conf.ecaade.2019.1.207
summary	The material-based studies examine through computation and physical prototyping layered composites for thermal responsive building envelopes. Focus is placed on surveying and computing a large series of materials across four groups, for then to test these materials from factors of solar energy reception capacities, internal heating methods, heat isolation coatings and layer bonding. An oak-polyethylene structure is developed based on the first studies and further tested towards implementation as part of an adaptive envelope demonstrator, with these studies focused on fabrication and assembly methods. Results of the developed, tested and applied composite as part of an adaptive envelope shows that the environmental-material composite is strongly influenced by colour and direct solar radiation exposure. This in turn allow a material-fabrication approach to program a responsive system driven by exergy. Reinforcing the responsive reaction of the composite by internal heating does not advance the performance, as coatings are needed to maintain the heat inside the material, which adds weight and isolate the composite from the thermal environment that otherwise is intended to provide the energy for driving the responsive behaviour.

summary	During the last decade, mass customization in developing countries has been rising. The combination of conventional methods and materials with computer numeric control technologies offers a possibility of merging established craftsmanship to the production of personalized components with mass production efficiency. This article aims to present the development of a facade component prototype as a means to prospect possibilities for mixing parametric design and digital fabrication to casting, especially in developing countries like Brazil. This is an applied research with an exploratory and constructive approach, which was a result of a graduate class structured on a research by design basis. The conceptual development and prototyping of the artifact followed iterative cycles, considering its performance, fabrication methods and feasibility. The selection of materials that are commonly used in Brazilian architecture, like concrete, facilitates the component adoption as as a facade solution. The main conclusion emphasizes the need of involvement between academia and industry for the development of innovative products and processes, and highlights different levels of mass customization to include a range of manufacturing agents, from major industries to local craftspeople.

summary	Excessive use of aggregate materials and metals in construction should be balanced by increasing use of construction materials from annually renewable resources based on natural lignocellulosic fibers. Parametric design tools gave here a possibility of using an alternative newly developed biocomposite material, for realization of complex geometries. Contemporary digital fabrication tools have enabled precise manufacturing possibilities and sophisticated geometry-making to take place that helped in obtaining high structural behavior of the overall global geometry of the discussed project. This paper presents a process of realizing an experimental structure made from Natural Fiber-Reinforced Polymers (NFRP)- also referred to as biocomposites, which were synthesized from lignocellulosic flexible core reinforced by 3D-veneer layers in a closed-moulding vacuum-assisted process. The biocomposite sandwich panels parameters were developed and defined before the final properties were imbedded in the parametric model. This paper showcases the multi-disciplinarity work between architects, structural engineers and material developers. It allowed the architects to work on the material development themselves and enabled to apply a new created design philosophy by the first author, namely applying ‘Materials as a Design-Tool’. The erected biocomposite segmented shell construction allowed a 1:1 validation for the whole design process, material development and the digital fabrication processes applied. The whole development has been reached after merging an ongoing industrial research project results with academic education at the school of architecture in Stuttgart-Germany.

title	Soft Additive Fabrication Processes: Material Indeterminacy in 3D Printing

summary	This description of Soft Additive Fabrication Processes, documents ways in which chance and randomness might be treated as values rather than problems. The production of a series of robotically controlled extruder experiments explore integrating material volition with the rigid order of machine control. Specifically this paper outlines the development of tooling procedures that harness emergent conditions in the automation of qualitative material effects. A key question for the research asks, how might architects imagine a design and construction scenario, which is no longer confined to prescriptive material dimensions, but is instead driven by digitally calibrated stochastic material processes? What opportunities might arise from developing an automated system, which does not rely on direct translation, but instead operates and predicts outcomes within a range of potential results?

summary	This research explores the potentials, limitations, and advantages of 3D printing watersoluble formwork for reinforced concrete applications. Using polyvinyl alcohol (PVA) forms and Polylactic Acid (PLA) filament with ground steel tensile reinforcement, this project explores the constraints and opportunities for architects to design and construct reinforced concrete using water soluble 3D printed formwork with embedded reinforcement. Research began with testing small PVA prints for consistency, heat of water-temperature for dissolving, and wall thickness of the printed formwork. Then, dual-extrusion desktop additive manufacturing was used as a method for creating a larger form to test the viability of translating this research into architectural scale applications. This paper describes the background research, materials, methods, fabrication process, and conclusions of this work in progress.
