title	Open Source Factory: Democratizing Large-Scale Fabrication Systems
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 660- 669

summary	Open source frameworks have enabled widespread access to desktop-scale additive manufacturing technology and software, but very few highly hackable large-scale or industrial open source equipment platforms exist. As research trajectories continue to move towards large-scale experimentation and full-scale building construction in robotic and digital fabrication, access to industrial fabrication equipment is critical. Large-scale digital fabrication equipment usually requires extensive start-up investments which becomes a prohibitive factor for open research. Expanding on the idea of the Fab Lab as well as the RepRap movement, the Open Source Factory takes advantage of disciplinary expertise and trans-disciplinary knowledge in construction machine design accumulated over the past decade. With the goal to democratize access to large-scale industrial fabrication equipment, this paper outlines the creation of two full-scale fabrication systems: a RepRap based large-scale 3-axis open source CNC gantry and a 6-axis industrial robot system based on a decommissioned KUKA KR200/2. Both machines offer radically different economic frameworks for implementing research in advanced full scale robotic fabrication into contexts of pedagogy, the research lab, practice, or small scale local building industry. This research demonstrates that such equipment can be implemented by building on the current knowledge base in the field. If industrial robots and other large-scale fabrication tools become accessible for all, the collective sharing of research and the development of new ideas in full-scale robotic building construction can be substantially accelerated.

summary	This paper explores the process of digital materialization through robotic fabrication techniques by presenting three wooden projects. The analysis of the case studies is oriented to underline the impact that computation had on architectural construction due to its methodological and instrumental innovations over the last decades. The absorption of computing and digital fabrication logics within the discipline is explored from either an architectural point of view and from the improvements related to automation of the constructive process. On the one hand the case studies are caught because of the desire to expand material complexity and, on the other hand because of the integration with other technological systems. The narrative allows gathering pros and cons in three different investigative macro areas: material culture, methodological oversights, and operative setbacks coming from digital machine and communicational constraints. This analytical investigation helps the definition of a new pathway for future researches, looking forward the assimilation of digital materiality learning in building construction.

title	Fabricação Digital Aplicada à Habitação de Caráter Emergencial: Um estudo sobre a adaptação de WikiHouses ao contexto ambiental brasileiro [Digital Fabrication Applied to Temporary Houses for Post-disaster and Social Emergency: A study on the adaptation of WikiHouses to the Brazilian tropics]
source	SIGraDi 2017 [Proceedings of the 21th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-227-439-5] Chile, Concepción 22 - 24 November 2017, pp.358-366
summary	Digital fabrication has transformed the way buildings are constructed by applying methods such as friction-fit connection. This technique has been propagated by WikiHouse which aims to develop open building technologies to different environmental contexts. However, the indiscriminate use of the model may result in inefficiency of housing performance. This work, therefore, investigates solutions for adapting WikiHouses to the tropics, according to principles proposed by Armando de Holanda in ‘A Guide to Build in Northeast Brazil’. Nevertheless, difficulties related to certain adaptations were observed such as connections compatibility and design of large open spaces, especially because these systems depend on a maximum size of parts.

summary	Aiming the application of digital fabrication in the production of architectural structures, the experimentation described in this paper has focused on the production of joints of gantry components machined in a CNC Router. Our goals are, in the long terms, to reduce costs in the production of social housing through the application of technologies already consolidated in other areas of knowledge. Thus, the article will describe the production of a real-scale prototype of a part of the structure of a residential unit, adapting an Open Source construction system (Wikihouse).

summary	This paper presents the research development for a base structural module for the Casa Nordeste project. Casa Nordeste is a compact housing experiment that will participate in the Solar Decathlon Latin America competition. It consists of a modular building that houses living, cooking, and sanitizing space. Developments presented are based on digital design and fabrication principles and processes, through algorithms that allow its customization. In this sense, discussions begin with a brief theoretical discussion about the concepts that underline the project: evolutionary housing; digital technologies that improve design and construction; open source construction and generative design systems. The paper finalizes by presenting and discussing developments of three different design aspects of the structural module: (a) geometry of the frames, (b) its modulation, and (c) fittings and joining mechanisms.

summary	Despite the cutting edge developments in science and technology, architecture to a large extent still tends to favor form over matter by forcing materials into predefined, often superficial geometries, with functional aspects relegated to materials or energy demanding mechanized systems. Biomaterials research has instead shown a variety of physical architectures in which form and matter are intimately related (Fratzl, Weinkamer, 2007). We take inspiration from the morphogenetic processes taking place in plants' leaves (Sharon et al., 2007), where intricate three-dimensional surfaces originate from in-plane growth distributions, and propose the use of 3D printing on pre-stretched textiles (Tibbits, 2017) as an alternative, material-based, form-finding technique. We 3D print open fiber bundles, analyze the resulting wrinkling phenomenon and use it as a design strategy for creating three-dimensional textile surfaces. As additive manufacturing becomes more and more affordable, materials more intelligent and robust, the proposed form-finding technique has a lot of potential for designing efficient textile structures with optimized structural performance and minimal usage of material.

title	A Robotic Fabrication Methodology for Dovetail and Finger Jointing: An Accessible & Bespoke Digital Fabrication Process for Robotically-Milled Dovetail & Finger Joints
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 456- 463

summary	Since the advent of industrialized processes in modern construction industries, the development of and relationship between computer-aided tools of design and computer-controlled tools of fabrication has steadily yielded new and innovative construction methodologies. Whilst industry has adopted many of these innovations for use by highly efficient machines and flexible processes, their operation is often highly dependent on industrial scales of production, and thus often inaccessible for small-scale, bespoke and affordable application. The prototype integrated joint milling methodology, case study and open-source software plugin ‘Dove’ presented in this paper, explores the efficacy of algorithmic processes in dynamically generating complex tooling paths and machine code for fabrication of bespoke dovetail and finger joints on a 6-axis industrial robot. The versatility, speed and precision of 6-axis robotic milling, allows us to liberate the efficiency, integrity and aesthetic of the dovetail and finger joint types from traditional application, and apply them to new architectures involving mass-customisation, complex form, and diverse materialities. In the development of full-immersion milling toolpaths and back-face filleting techniques that drastically reduce cutting times, tool path complexity and material waste, this study seeks to build upon past and current research by proposing a comparatively simple, efficient and more intuitive approach to robotically-fabricated integrated jointing for application at a variety of scales.

summary	The capacity to respond dynamically to changes in external and internal environments open new possibilities in the interaction between buildings, humans and the environment. The development of dynamic envelopes requires the integration of various systems- geometric, structural, and electronic-responsive and their interaction. The paper reports the results from the "Dynamic Cloud Project" and presents a design and fabrication methodology to integrate kinetic behaviour with material constraints; the simulation of responses by connecting components with programmable input and behaviour. The paper presents a modular, component-driven systems construction based on a carrier-component surface geometry called responsive carrier-component envelope (RCCE) and describes the modelling, fabrication and assembly of such envelopes. The protocols developed in the project are reported in the paper and highlight the opportunities and consequences of how local components relate to the whole carrier envelope with multiple constraints and scale considerations. The results of the prototyping and experimentation with this project are reported in the paper. The paper also discusses future applications of the research and outlines new possibilities and design opportunities in prototyping responsive carrier-component envelopes.

title	Non-Linear Matters: Auxetic Surfaces
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 392- 403
doi	https://doi.org/10.52842/conf.acadia.2017.392
summary	Auxetic structures exhibiting non-linear buckling are a prevalent research topic in the material sciences due to the ability to tune their reversible actuation, porosity, and negative Poisson’s ratio. However, the research is limited to feature sizes at scales below 10 mm2, and to date, there are no available efficient design and prototyping methods for architectural designers. Our study develops design principles and workflow methods to transform standard materials into auxetic surfaces at an architectural scale. The auxetic behavior is accomplished through buckling and hinging by subtracting from a homogeneous material to create perforated patterns. The form of the perforations, including shape, scale, and spacing, determines the behavior of multiple compliant "hinges" generating novel patterns that include scaling and tweening transformations. An analytical method was introduced to generate hinge designs in four-fold symmetric structures that approximate non-linear buckling. The digital workflow integrates a parametric geometry model with non-linear finite element analysis (FEA) and physical prototypes to rapidly and accurately design and fabricate auxetic materials. A robotic 6-axis waterjet allowed for rapid production while maintaining needed tolerances. Fabrication methods allowed for spatially complex shaping, thus broadening the design scope of transformative auxetic material systems by including graphical and topographical biases. The work culminated in a large-scale fully actuated and digitally controlled installation. It was comprised of auxetic surfaces that displayed different degrees of porosity, contracting and expanding while actuated electromechanically. The results provide a promising application for the rapid design of non-linear auxetic materials at scales complimentary to architectural products.

title	Fibrous Aerial Robotics - Study of spiderweb strategies for the design of architectural envelopes using swarms of drones and inflatable formworks

doi	https://doi.org/10.52842/conf.ecaade.2017.1.689
summary	This thesis research presents an integrated workflow for the design and fabrication of large-scale architectural envelopes using swarms of drones and inflatable structures as formworks. The work lies at the intersection of architecture, biology and robotics, incorporating generative design with digital fabrication techniques. The proposed approach aims to investigate the tectonic potential of computational systems which encode behavioral strategies inside an agent-based model. It is from local interactions taking place at the micro-scale of complex systems that a new set of architectural tendencies seem to emerge. The authors focused on the strategies developed by colonies of social spiders during the construction of three-dimensional webs. Their communication system and the characteristics of the material structure have been then modelled and translated in a digital environment. A physical fabrication process, in which the simulated agents become drones in a real world environment, was concurrently developed. The goal was to investigate the architectural possibilities given by an autonomous aerial machine depositing fibrous material over inflatable formworks and its potential usefulness in specific sites where overall conditions don't allow traditional construction techniques.

title	Fabrication of Complex Clay Structures Through an Augmented Reality Assisted Platform
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 413–422
doi	https://doi.org/10.52842/conf.caadria.2023.1.413
summary	The relationship between clay manufacturing and architectural design has a long trajectory that has been explored since the early 2000s. From a 3D printing or assembly perspective, using clay in combination with automated processes in architecture to achieve computational design solutions is well established. (Yuan, Leach & Menges, 2018). Craft-based clay art, however, still lacks effective computational design integration. With the improvement of Augmented Reality (AR) technologies (Driscoll et al., 2017) and the appearance of digital platforms, new opportunities to integrate clay manufacturing and computational design have emerged. The concept of digitally transferring crafting skills, using holographic guidance and machine learning, could make clay crafting accessible to more workers while creating the potential to share and exchange digital designs via an open-source manufacturing platform. In this context, this research project explores the potential of integrating computational design and clay crafting using AR. Moreover, it introduces a platform that enables AR guidance and the digital transfer of fabrication skills, allowing even amateur users with no prior making experience to produce complex clay components.

summary	Physarum Polycephalum is a widespread eukaryotic microbe capable of producing effective networks between food particles to solve spatial planning problems. This paper investigates a previous algorithm for simulating Physarum Polycephalum. An open-source tool named Physarealm is developed for simulation in Rhino's graphical algorithm editor, Grasshopper. The tool adopts a previous stigmergic multi-agent algorithm for simulation and expands its boundary into three dimensions. In addition, this tool adds some custom rules, thus giving the designer more creative control over the produced results. Two research projects have applied this tool in the design process. The first project mainly takes advantage of the tool's path-planning ability, while the second one utilizes its aesthetic values, demonstrating the potential of the tool for further applications.

doi	https://doi.org/10.52842/conf.caadria.2017.467
summary	Recent developments in Additive Manufacturing are creating possibilities to make not only rapid prototypes, but directly manufactured customised components. This paper investigates the potential for combining standard building materials with customised nodes that are individually optimised in response to local load conditions in non-standard, irregular, or doubly curved frame structures. This research iteration uses as a vehicle for investigation the SmartNodes Pavilion, a temporary structure with 3D printed nodes built for the 2015 Bi-City Biennale of Urbanism/Architecture in Hong Kong. The pavilion is the most recent staged output of the SmartNodes Project. It builds on the findings in earlier iterations by introducing topologically constrained node forms that marry the principals of the evolved optimised node shape with topological constraints imposed to meet the printing challenges. The 4m high canopy scale prototype structure in this early design research iteration represents the node forms using plastic Fused Deposition Modelling (FDM).

summary	Reciprocal Frame Structures (RF) have broad application potentials. Flexible to using small available materials, they span large areas, including varied curvature and doubly-curved forms. Although not many buildings using RF have been constructed to date, records indicate RF efficiencies where timber was widely used in structures predating modern construction. For reasons of adaptability and economy, advances in computation and fabrication precipitated increase in research into RF structures as a contemporary architectural typology. One can observe that linear timber such as rods and bars feature in extensive RF research. However, interest in planar RF has only recently emerged in research. Hence one can argue that planar RF provides depth to explore new design possibilities. This paper contributes to the growing knowledge of planar RF by presenting a design project that demonstrates an approach in notching systems to explore design and structural performance. The design project, the developed design workflow, fabrication, assembly and evaluation are discussed in this paper.

doi	https://doi.org/10.52842/conf.caadria.2019.2.451
summary	This paper presents an innovative approach on designing large-scale spatial structure with automated robotic 3D-printing. The incipient design approach mainly focused on optimizing structural efficiency at an early design stage by transform the object into a discrete system, and the elements in this system contains unique structural parameters that corresponding to its topology results of stiffness distribution. Back in 2017, the design team already implemented this concept into an experimental project of Cloud Pavilion in Shanghai, China, and the 3D-printed spatial structure was partitioned into five zones represent different level of structure stiffness and filled with five kinds of unit toolpath accordingly. Through further research, an upgrade version, the project of Cloud Pavilion 2.0 is underway and will be completed in January 2019. A detailed description on innovative printing toolpath design in this project is conducted in this paper and explains how the toolpath shape effects its overall structural stiffness. This paper contributes knowledge on integrated design in the field of robotic 3D-printing and provides an alternative approach on robotic toolpath design combines with the optimized topological results.

summary	The consequences of automation technology on industry are currently widely discussed in terms of future tasks, work organisation and working environments. Even though various novel education programmes specialise in digital fabrication, relatively little has been written on concepts for a deeper integration of digital technologies in the architectural curriculum. This paper gives an overview of interdisciplinary educational approaches and digital project development techniques and describes a teaching method featuring intensive collaboration with research and industry, an iterative teaching method employing digital production of large-scale prototypes and a moderated self-learning process. We describe two examples of teaching initiatives in particular that were undertaken at TU Munich and ETH Zurich and analyse their results in terms of physical outcomes, teaching accomplishments, resource efficiency and connection to research. We discuss the relationship between necessary teaching intensity, project size and complexity of digital fabrication equipment and conclude by giving an outlook for future initiatives.

summary	Fiber composite materials have tremendous potential in architectural applications due to their high strength-to-weight ratio and their ability to be formed into complex shapes. Novel fabrication processes can be based on the unique affordances and characteristics of fiber composites. Because these materials are lightweight and have high tensile strength, a radically different approach to fabrication becomes possible, which combines low-payload yet long-range machines—such as unmanned aerial vehicles (UAV)—with strong, precise, yet limited-reach industrial robots. This collaborative concept enables a scalable fabrication setup for long-span fiber composite construction. This paper describes the integrated design process and design development of a large-scale cantilevering demonstrator, in which the fabrication setup, robotic constraints, material behavior, and structural performance were integrated in an iterative design process.

summary	There has been significant research into large-scale 3D printing processes with industrial robots. These were initially used to extrude in a layered manner. In recent years, research has aimed to make use of six degrees of freedom instead of three. These so called "spatial extrusion" methods are based on a toolhead, mounted on a robot arm, that extrudes a material along a non horizontal spatial vector. This method is more time efficient but up to now has suffered from a number of limiting geometrical and structural constraints. This limited the formal possibilities to highly repetitive truss-like patterns. This paper presents a generalised approach to spatial extrusion based on the notion of discreteness. It explores how discrete computational design methods offer increased control over the organisation of toolpaths, without compromising design intent while maintaining structural integrity. The research argues that, compared to continuous methods, discrete methods are easier to prototype, compute and manufacture. A discrete approach to spatial printing uses a single toolpath fragment as basic unit for computation. This paper will describe a method based on a voxel space. The voxel contains geometrical information, toolpath fragments, that is subsequently assembled into a continuous, kilometers long path. The path can be designed in response to different criteria, such as structural performance, material behaviour or aesthetics. This approach is similar to the design of meta-materials - synthetic composite materials with a programmed performance that is not found in natural materials. Formal differentiation and structural performance is achieved, not through continuous variation, but through the recombination of discrete toolpath fragments. Combining voxel-based modelling with notions of meta-materials and discrete design opens this domain to large-scale 3D printing. Please write your abstract here by clicking this paragraph.
