summary	Additive manufacturing techniques and materials have evolved rapidly during the last decade. Applications in architecture, engineering and construction are getting more attention as 3D printing is trying to find its place in the industry. Due to high material prices for metal 3d printing and in-homogenous material behaviour in printed plastic, 3D printing has not yet had a very significant impact at the scale of buildings. Limitations on scale, cost, and structural performance have also hindered the advancement of the technology and research up to this point. The research presented here takes a case study for the application of 3D printing at a furniture scale based on a novel custom optimisation approach for structural nodes. Through the concentration of non-standard geometry on the highly complex custom optimised nodes, 3D printers at industrial product scale could be used for the additive manufacture of the structural nodes. This research presents a design strategy with a digital process chain using parametric modeling, virtual prototyping, structural simulation, custom optimisation and additive CAD/CAM for a digital workflow from design to production. Consequently, the digital process chain for the development of structural nodes was closed in a holistic manner at a suitable scale.

title	Clay Non-Wovens: Robotic Fabrication and Digital Ceramics
doi	https://doi.org/10.52842/conf.acadia.2017.502
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. 502- 511
summary	Clay Non-Wovens develops a new approach for robotic fabrication, applying traditional craft methods and materials to a fundamentally technical and precise fabrication methodology. This paper includes new explorations in robotic fabrication, additive manufacturing, complex patterning, and techniques bound in the arts and crafts. Clay Non-Wovens seeks to develop a system of porous cladding panels that negotiate circumstances of natural daylighting through parameters dealing with textile (woven and non-woven) patterning and line typologies. While additive manufacturing has been built predominantly on the basis of extrusion, technological developments in the field of 3D printing seldom acknowledge the bead or line of such extrusions as more than a nuisance. Blurring of recognizable layers is often seen as progress, but it does away with visible traces of a fabrication process. Historically, however, construction methods in architecture and the building industry have celebrated traces of making ranging from stone cutting to log construction. With growing interest in digital craft within the fields of architecture and design, we seek to reconcile our relationship with the extruded bead and reinterpret it as a fiber and three-dimensional drawing tool. The traditional clay coil is to be reconsidered as a structural fiber rather than a tool for solid construction. Building upon this body of robotically fabricated clay structures required the development of three distinct but connected techniques: 1. construction of a simple end effector for extrusion; 2. development of a clay body and; 3. using computational design tools to develop formwork and toolpath geometries.

title	High-performance Spatial Composite 3D Printing

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 166-171.
summary	This project explores the advantages of employing continuum material topology optimization in a 3D non-standard lattice structure through fiber additive manufacturing processes (Figure 1). Additive manufacturing (AM) has gained rapid adoption in architecture, engineering, and construction (AEC). However, existing optimization techniques often overlook the mechanical anisotropy of AM processes, resulting in suboptimal structural properties, with a focus on layer-by-layer or planar processes. Materials, processes, and techniques considering anisotropy behavior (Kwon et al. 2018) could enhance structural performance (Xie 2022). Research on 3D printing materials with high anisotropy is limited (Eichenhofer et al. 2017), but it holds potential benefits (Liu et al. 2018). Spatial lattices, such as space frames, maximize structural efficiency by enhancing flexural rigidity and load-bearing capacity using minimal material (Woods et al. 2016). From a structural design perspective, specific non-standard lattice geometries offer great potential for reducing material usage, leading to lightweight load-bearing structures (Shelton 2017). The flexibility and freedom of shape inherent to AM offers the possibility to create aggregated continuous truss-like elements with custom topologies.

title	SmartNodes Pavilion - Towards Custom-optimized Nodes Applications in Construction
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	The research projects in this paper examine the notion of soft systems relative to machine induced material consequences. It asks, how might we integrate processes and methods which leave tolerances for indeterminacy and flexibility into design and construction? The two projects outlined investigate change of state materials paired with automation strategies, focusing on additive processes with thermally induced material configurations and programmable matter with magnetically controlled formations.

title	Soft Computing in Design: Developing Automation Strategies from Material Indeterminacies
source	Gülen Çagdas, Mine Özkar, Leman F. Gül and Ethem Gürer (Eds.) Future Trajectories of Computation in Design [17th International Conference, CAAD Futures 2017, Proceedings / ISBN 978-975-561-482-3] Istanbul, Turkey, July 12-14, 2017, pp. 419-430.
summary	Integrating concepts of soft computation into advanced manufacturing and architecture means perceiving the element of chance not as a hindrance, but as an opportunity. The projects examined in this manuscript explore opportunities for integrating material indeterminacy into advanced manufacturing by pairing a certain degree material unpredictability with the rigid order of machine control. The three projects described investigate three common categories of automated tooling including additive processes, subtractive processes and molding / casting processes. Each project begins with the question, what opportunities might arise from the mediation between material volition and computational control? By embracing indeterminate material results and taking an optimistic stance on chance and uncertainty, which are usually treated as problems rather than values, the intent is to provide ways for automating unique material effects and explore the opportunities for integrating soft computing in design.

title	Small 3D Printers / Large Scale Artifacts - Computation for Automated Spatial Lattice Design-to-Fabrication with Low Cost Linear Elements and 3D Printed Nodes
doi	https://doi.org/10.52842/conf.caadria.2017.821

summary	The presented process enables users to design, fabricate and assemble spatial lattices comprised of linear stock materials such as round section timber, aluminum or acrylic dowels and complex 3D printed joints. The motivation for the development of this application is informed by the incredible availability of low cost 3D printers which enable anyone to produce small scale artifacts; deploying rapid prototyping to achieve larger scale artifacts than the machine's effective work envelope is a challenge for additive manufacturing; and the trend in the design computing world away highly technical specialized software towards general public applications.

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.

summary	This research explores the use of large-scale 3D Printing techniques in architecture and structural design. First we will analyse the various methods in large-scale 3D printing in order to choose the method with the most potential to be used to build large-scale residential buildings in the Netherlands. Then we will investigate the properties of this 3D printing technique to determine the new building process, related to building with a 3D Concrete Printer. The freedom in movement of the printer and the properties of the concrete mixture used to print will form the guidelines in the creation of a design language in which both material costs and labour costs are reduced to a minimum. The design language is later applied on the design of a house, which shows the impact 3D Concrete Printing should have on the current boundaries in architecture and structural design.

summary	We present the initial findings of our research project aiming at development of a 3D-printing process for wood composites. The 3D-printing method employed is based on material extrusion principle and utilizes industrial robotics for position and motion control. The unique characteristic of our approach is in the development of the material where we employ exclusively organic components for both the matrix and reinforcement; a decision informed by prioritizing environmental considerations.

title	Tornado Pavilion - Simplexity, almost nothing, but human expanded abilities

summary	In the context of the fourth industrial revolution, not all regions have the same access to technology for project development. These technological limitations do not necessarily result in worst projects and, on the contrary, can stimulate creativity and human intervention to overcome these shortcomings. We report here the design of a small pavilion with scarce budget and an ambitious goal to qualify a space through tactical urbanism. We develop the project in a multidisciplinary partnership between academy and industry, designing, manufacturing and assembling Tornado Pavilion, a complex structure using combined HIGH-LOW technologies, combining visual programming with analog manufacture and assembly. The design strategy uses SIMPLEXITY with ruled surfaces strategy to achieve a complex geometry. Due to the lack of automated mechanical cutting or assembly, we used human expanded abilities for the construction; instead of a swarm of robots, we had a motivated and synchronized swarm of students. The pavilion became a reference for local population that adopted it. This process thus shows that less or almost nothing (Sola-Morales 1995), need not to be boring (Venturi 1966) but less can be much more (Kolarevic 2017).

title	Constructive Design: Rule Discovery for 3D Printing Decomposed Large Objects
source	Gülen Çagdas, Mine Özkar, Leman F. Gül and Ethem Gürer (Eds.) Future Trajectories of Computation in Design [17th International Conference, CAAD Futures 2017, Proceedings / ISBN 978-975-561-482-3] Istanbul, Turkey, July 12-14, 2017, pp. 431-442.
summary	This paper presents a rule discovery process for designers that work with physically large 3D printed models. After a period of discovery, rules were formalized, then developed into operations and programmable functions used in a generative design system. Past examples of generative systems are built based on visual constraints leading to graphical outcomes. With the emergence of 3D printing, we introduce ideas for rule building based on physical constraints and outcomes. The decomposition rules are: curved surface slicing, freestanding attribute, interval patterning, edge mating, and pneumatic attribute. The freestanding attribute, the most novel rule, is based on Chilean anti-earthquake building techniques. This rule provides the greatest degree of structural stability to a model. We conclude with a discussion of results from the case study used to generate the set constructive rules. We believe this method of module generation, 3D Printing and assembles can support design prototyping and model manufacturing across scales.

title	Fabrication of Complex Clay Structures Through an Augmented Reality Assisted Platform

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.

title	Open Source Factory: Democratizing Large-Scale Fabrication Systems
doi	https://doi.org/10.52842/conf.acadia.2017.660

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	The aim of the paper is to identify parameters that influence perceived urban density. Whilst it is standard for architects and planners to consider urban density, there is often no consideration of how individuals might perceive such density. We report the findings of a study in which participants rate photographs of urban scenes according to perceived urban density. The case study area is central Zurich, Switzerland. The images are analyzed according to six parameters: visibility, amount of buildings, street width, amount of sky, amount of green space, and amount of vehicles. We report the findings of where images were ranked along a scale from lowest to highest perceived urban density. Findings show that visibility alone is not enough to explain the rating of perceived urban density. The study is a first step towards reaching a definition of perceived urban density that can be applied to different urban contexts.

title	Towards Force-aware Robot Collectives for On-site Construction
doi	https://doi.org/10.52842/conf.acadia.2017.382

summary	Due to the irregular and variable environments in which most construction projects take place, the topic of on-site automation has previously been largely neglected in favor of off-site prefabrication. While prefabrication has certain obvious economic and schedule benefits, a number of potential applications would benefit from a fully autonomous robotic construction system capable of building without human supervision or intervention; for example, building in remote environments, or building structures whose form changes over time. Previous work using a swarm approach to robotic assembly generally neglected to consider forces acting on the structure, which is necessary to guarantee against failure during construction. In this paper we report on key findings for how distributed climbing robots can use local force measurements to assess aspects of global structural state. We then chart out a broader trajectory for the affordances of distributed on-site construction in the built environment and position our contributions within this research agenda. The principles explored in simulation are demonstrated in hardware, including solutions for force-sensing as well as a climbing robot.

title	vSpline: Physical Design and the Perception of Scale in Virtual Reality

summary	Virtual reality provides a heightened sense of immersion and spatial awareness that provides a unique opportunity for designers to perceive and evaluate scale and space. At the same time, traditional sketches and small-size physical models provide tactile feedback that allow designers to create, comprehend, and explore complex geometric relationships. Through the development of vSpline, a modeling application for virtual reality, we explore the potential for design within a virtual spatial environment to blur the boundaries between digital and physical stages of design, and seek to combine the best of both virtual and analog worlds. By using spline-based closed meshes created directly in three-dimensional space, our software provides the capabilities to design, modify, and save the information in the virtual world and seamlessly convert the data to evaluate the printing of 3D physical models. We identify and discuss important questions that arise regarding relationships of perception of scale, digital-to-physical domains, and new methods of input and manipulation within a 3D immersive space.

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 introduction of robotics into the field of 3D printing allows designers and fabricators to truly print in three dimensions, focusing more on the volumetric properties of the extrusion rather than two-dimensional slicing and, furthermore, introducing forces that can defy gravity. This paper introduces a new method of robotic extrusion using magnetic fields to construct ferrostructures. Using a custom tool and ferromagnetic material, the research develops a construction process utilizing the off-plane toolpaths of a 6-axis industrial robotic arm to pull, attract, and repel material into a hardened structure. The ferromagnetic liquid forms spikes and connections around the invisible magnetic fields, and upon hardening, freezes the field into a new physical artifact. This extrusion process allows a fabrication that defies gravity. The robotic fabrication process allows microextrusions to build off of one another, scaling the result to approach an architectural scale and bringing a new freedom to the designer and the fabricator.

summary	We present a proof of concept of parametric 3D models of fully associative geometry and milling tool paths for the robotic machining of traditional timber joints, using a visual robot-programming environment integrated into a popular CAD software. A representative sample of traditional timber joints was obtained from a field survey conducted in Valparaíso, Chile. Each specimen was theoretically validated in nearly half a hundred carpentry treatises and manuals corresponding to the historical period in which the surveyed buildings were built. Parametric robotic milling prototypes were experimentally validated in manufacturing process using two industrial robots with different spindles and cutting tools.
