title	Rationalization of freeform space-frame structures: Reducing variability in the joints
source	International Journal of Architectural Computing vol. 18 - no. 1, 84-99
summary	In recent years, the application of space-frame structures on large-scale freeform designs has significantly increased due to their lightweight configuration and the freedom of design they offer. However, this has introduced a level of complexity into their construction, as doubly curved designs require non-uniform configurations. This article proposes a novel computational workflow that reduces the construction complexity of freeform space-frame structures, by minimizing variability in their joints. Space-frame joints are evaluated according to their geometry and clustered for production in compliance with the tolerance requirements of the selected fabrication process. This provides a direct insight into the level of customization required and the associated construction complexity. A subsequent geometry optimization of the space-frame’s depth minimizes the number of different joint groups required. The variables of the optimization are defined in relation to the structure’s curvature, providing a direct link between the structure’s geometry and the optimization process. Through the application of a control surface, the dimensionality of the design space is drastically reduced, rendering this method applicable to large-scale projects. A case study of an existing structure of complex geometry is presented, and this method achieves a significant reduction in the construction complexity in a robust and computationally efficient way.

title	Sensibility at Large - A Post-Anthropocene Vision for Architectural Landscape Editing

summary	The irreversible imprint of humankind on Earth calls for revisiting current construction practices. This paper forwards a vision for post-Anthropocene, large-scale, architectural, and landscape construction. This vision relates to transforming natural terrains into architecture using on-site robotic tools and enabling greater sustainability through increased sensibility. Despite advancements in large-scale digital fabrication in architecture, the field still mainly focuses on the production of objects. The proposed vision aims to advance theory and practice towards territorial scale digital fabrication of environments. Three notions are proposed: material-aware construction, large-scale customization, and integrated fabrication. These aspects are demonstrated through research and teaching projects. Using scale models, they explore the deployment of robotic tools toward reforming, stabilizing, and reconstituting soil in an architectural context. Together, they propose a theoretical ground for in situ digital fabrication for a new era, relinking architecture to the terrains upon which it is formed.

summary	This paper reviews and explores the topological properties of surface disclinations applied to elastic sheets and suggests how these properties may be reproduced at an architectural scale. A variety of surface disclinations and their translation from digital and physical formfinding processes to thin plywood prototypes are discussed. Initial phases of this research have been focused on the bending behavior of various sheet disclination types and have studied a variety of computational form-finding techniques that demonstrate this behavior in an architectural workflow. Several large-scale prototypes of architectural disclinations were produced to test the scalability of topologically induced surface curvature, discussed within the context of bending-active plate structures.

summary	This paper provides an overview of "Architasker", a large-scale crowdsourcing approach, platform, and method that enables a collaborative professional architectural design process in collaboration with a community of stakeholders. The platform includes communicating complex architectural project requirements; solution space exploration using different micro-tasks like sketching, 2D and 3D CAD; design selection; and design review as an evolutionary process. The architectural crowdsourcing model underlying the platform is contextualized in the state-of-the-art research on creative crowdsourcing methods and is supported by relevant evidence from empirical experiments. Experimental results validate the effectiveness of the method to generate architectural artifacts by harnessing the skills, talents, and experience of architects and the opinions and values of the stakeholders.

title	Responsive Surface Design to Reduce the Urban Heat Island Effect (UHI)
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 945-952
summary	The present project aims to influence the reduction of the urban heat island effect (UHI) by designing sensitive surfaces that respond to changes in temperature. This research presents a scenario with a vision of cities with adaptive designs that is generated from the insertion of elements sensitive to the environment (elements that respond to environmental stimuli). Responsive elements become constant factors in small-scale or large-scale design that transform the way environment is changed to a sensitive and resilient urban environment against possible adverse environmental conditions.

title	Impact of Robotic 3D Printing Process Parameters on Bond Strength
doi	https://doi.org/10.52842/conf.acadia.2020.1.594
source	ACADIA 2020: Distributed Proximities / Volume I: Technical Papers [Proceedings of the 40th Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-95213-0].

summary	Additive manufacturing (AM), also known as 3D printing, offers advantages over traditional construction technologies, increasing material efficiency, fabrication precision, and speed. However, many AM projects in academia and industrial institutions do not comply with building codes. Consequently, they are not considered safe structures for public utilization and have languished as exhibition prototypes. While three discrete scales—micro, mezzo, and macro—are investigated for AM with paste in this paper, structural integrity has been tackled on the mezzo scale to investigate the impact of process parameters on the bond strength between layers in an AM process. Real-world material deposition in a robotic-assisted AM process is subject to environmental factors such as temperature, humidity, the load of upper layers, the pressure of the nozzle on printed layers, etc. Those factors add a secondary geometric characteristic to the printed objects that was missing in the initial digital model. This paper introduces a heuristic workflow for investigating the impacts of three selective process parameters on the bond strength between layers of paste in the robotic-assisted AM of large-scale structures. The workflow includes a method for adding the secondary geometrical characteristic to the initial 3D model by employing X-ray computerized tomography (CT) scanning, digital image processing, and 3D reconstruction. Ultimately, the proposed workflow offers a pattern library that can be used by an architect or artificial intelligence (AI) algorithms in automated AM processes to create robust architectural forms.

summary	This paper aims to contribute to a history of computational design and to a historiography of the field by proposing a study of the development of sociotechnical networks of computation in architecture between 1965 and 2020 as shown in AD magazine. The research focuses on two aspects: (1) a methodological approach for the constitution of a comprehensive history of the field and the application of that methodology to a corpus of items published in AD, and (2) questions the relevance of the outlook into computational design as given by the magazine in comparison to a more comprehensive history taking into account other sources. First, the paper presents the history and the editorial line of AD, as well as its pertinence as a primary source. Second, a brief account of the history emerging from this research is given, with a focus on four different periods: pioneering research of the 1960s–1970s, emergence of 3D modeling tools and the procedural winter in the 1980s–1990s, constitution of a large-scale academic and professional network in the 2000s, and democratization of algorithmic design tools in the 2010s. Third, observations are made on editorial choices of the magazine and the biases of its account of computational research, with a special focus on the period 2000–2020, during which many issues have been dedicated to computational design themes, therefore making potential biases more visible. Despite the preponderance of specific topics, editors, and contributors, AD magazine provides an outlook into key concerns of the community at given times. The main biases identified, including a strong focus on the themes of biodesign and rationalization of practices, mirror the biases of the computational field itself, demonstrating the value of AD as an archive for the history of the field.

title	Horizontal Forming in Additive Manufacturing: Design and Architecture Perspective
doi	https://doi.org/10.52842/conf.caadria.2020.1.203

summary	Extrusion based three-dimensional additive manufacturing technology forms objects by driving the material through a nozzle depositing a linear structure through vector-building blocks called roads. In a common 3-axis system, the roads are stacked layer upon layer for forming the final object. However, forming overhanging geometry in this way requires additional support structures increasing material usage and effective printing time. The paper presents a novel Horizontal forming (HF) approach and method for forming overhanging geometry, HF is a new extrusion-based AM approach that allows rapid and stable forming of horizontal structures without additional support in 3-axis systems. This approach can provide new design and manufacturing possibilities for extrusion AM, with emphasis on medium and large-scale AM. HF can affect the outcome's aesthetic and mechanical properties. Moreover, it can significantly accelerate the production process and reduce material waste. The present paper maps the influence of various parameters employed in the HF method, providing a deeper understanding of the printing process. Additionally, it explores and demonstrates the potential functional and aesthetic characteristics that can be achieved with HF for industrial design and architectural products.

title	Super Composite: Carbon Fibre Infused 3D Printed Tectonics
doi	https://doi.org/https://doi.org/10.1007/978-981-33-4400-6_28
source	Proceedings of the 2020 DigitalFUTURES The 2nd International Conference on Computational Design and Robotic Fabrication (CDRF 2020)
summary	This research posits an innovative process of embedding carbon fibre as the primary structure within large-scale polymer 3D printed intricate architectural forms. The design and technical implications of this research are explored and demonstrated through two proto-architectural projects, Cloud Affects and Unclear Cloud, developed by the RMIT Architecture Snooks Research Lab. These projects are designed through a tectonic approach that we describe as a super composite – an approach that creates a compression of tectonics through algorithmic selforganisation and advanced manufacturing. Framed within a critical view of the lineage of polymer 3D printing and high tech fibres in the field of architectural design, the research outlines the limitations of existing robotic processes employed in contemporary carbon fibre fabrication. In response, the paper proposes an approach we describe asInfused Fibre Reinforced Plastic (IFRP) as a novel fabrication method for intricate geometries. This method involves 3D printing of sacrificial formwork conduits within the skin of complex architectural forms that are infused with continuous carbon fibre structural elements. Through detailed observation and critical review of Cloud Affects and Unclear Cloud (Fig. 2), the paper assesses innovations and challenges of this research in areas including printing, detailing, structural analysis and FEA modelling. The paper notes how these techniques have been refined through the iterative design of the two projects, including the development of fibre distribution mapping to optimise the structural performance.

title	A Large-Scale Measurement and Quantitative Analysis Method of Façade Color in the Urban Street Using Deep Learning
doi	https://doi.org/https://doi.org/10.1007/978-981-33-4400-6_9
source	Proceedings of the 2020 DigitalFUTURES The 2nd International Conference on Computational Design and Robotic Fabrication (CDRF 2020)
summary	Color planning has become a significant issue in urban development, and an overall cognition of the urban color identities will help to design a better urban environment. However, the previous measurement and analysis methods for the facade color in the urban street are limited to manual collection, which is challenging to carry out on a city scale. Recent emerging dataset street view image and deep learning have revealed the possibility to overcome the previous limits, thus bringing forward a research paradigm shift. In the experimental part, we disassemble the goal into three steps: firstly, capturing the street view images with coordinate information through the API provided by the street view service; then extracting facade images and cleaning up invalid data by using the deep-learning segmentation method; finally, calculating the dominant color based on the data on the Munsell Color System. Results can show whether the color status satisfies the requirements of its urban plan for façade color in the street. This method can help to realize the refined measurement of façade color using open source data, and has good universality in practice.

summary	In a climate where standard methods of construction are being challenged, developments in engineered timbers are allowing mass timber construction to be explored as a sustainable alternative to current building methods that can change the future of the built environment. Cross-laminated timber (CLT) is at the forefront of this evolution and, with the advancement in computational design and digital fabrication tools, there lies an opportunity to redefine standard construction. This project creates connections inspired by traditional Japanese joinery that have been adapted to be used for the panel construction of CLT structures. Using a combination of digital modelling and advanced digital fabrication, the project utilizes CLT offcuts as a primary connection material. The system not only reduces waste but also mitigates thermal bridging and lowers the number of connection points whilst increasing the ease of building and fabrication. Connection systems are designed and prototyped using a robotic arm and are then evaluated within the context of a building scale and considers largeâ€scale fabrication and onâ€site assembly whilst continuing to focus on the reduction of waste.

title	Parametric Photo V-Carve for Variable Surfaces

Online and Global. 24-30 October 2020. edited by B. Slocum, V. Ago, S. Doyle, A. Marcus, M. Yablonina, and M. del Campo. 484-493.
summary	This research project was part of the design and construction of the Memorial to Enslaved Laborers (MEL) at the University of Virginia (UVA). The MEL was dedicated to an estimated 4,000 enslaved persons who worked at UVA between 1817 and 1865. The 80-foot-diameter memorial is a tapered toroidal shape composed of 75 stone blocks. This project demonstrates how computational design tools along with robotic digital fabrication can be used to achieve unique social and experiential effects in an architectural application. The memorial’s design was informed by an extensive community engagement process that clarified the importance of including a visual representation of enslaved people on the memorial. With this input, the eyes of Isabella Gibbons were selected to be used as a symbolic representation of triumph on the outer wall of the memorial. The MEL project could not rely solely on prior methods or existing software applications to design and fabricate this portrait due to four particularities of the project: material, geometry, representation, and scale. To address these challenges, the MEL design team employed an interdisciplinary collaborative process to develop an innovative parametric design technique: parametric photo V-carve. This technique allowed the MEL design team to render a large-scale photo-realistic portrait into stone. This project demonstrates how the synthesis of artistic motivations, computational design, and robotic digital fabrication can develop unique expressions that shape personal and cultural experiences.

summary	Advances in computational form finding and simulation enable the creation of highly efficient structurally aware freeform geometries. Using significantly less material than standardized building elements there are significant challenges in their materialization. We present Voxelcrete, a discrete, voxel-based, reconfigurable slip formwork system for the creation of non-standard concrete structures. We aim to transition from highly individualized and complex formworks tailored for individual structures to simple formworks that can be reused and reconfigured to realize a variety of designs. Voxelcrete is a robotically tended formwork system in which modular formwork units are iteratively arranged for continuous casts of concrete. The system allows for the production of large scale concrete objects using reconfigurable, adaptive formwork. This paper shows the conceptualization and development of the system and expands on the existing notion of adaptive formwork

title	Transient Materialization â€“ Robotic Metal Curving
doi	https://doi.org/10.52842/conf.caadria.2020.2.423
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 2, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 423-432
summary	This paper introduces the notion of transient materialization to investigate a novel approach of robotic fabrication. Transient materialization explores a new logic of materialization that takes the advantage of differentiated material states to generate form at a particular moment through computation and fabrication technologies. Specifically, this design research explains a unique design and fabrication process, opening up a new method of materializing architectural form that emerges from the interweaving of data, the material capacity (plastic deformation), timing, and machine capacity. Hence, to examine this research direction, this paper conducts an experimental project, Robotic Metal Curving, through hands-on material experiments, as well as the development of algorithms, robot motion, and prototyping machines. This experiment utilizes an induction heating technique in cooperation with a six-axis industrial robotic arm and fabrication equipment used to shape each metal rod into a three-dimensional curve at a transient moment. In addition, the project focuses not only on developing a robotic metal curving system but also apply this technique in large scale by fabricating a wire-frame structure.

title	Research on Commercial Space Vitality of Airport Terminal Based on 3D Vision Field Simulation of Pedestrian Flows - Taking Guangzhou Baiyun International Airport Terminal 2 as a Study Case

summary	In recent years, more and more large-scale terminal buildings have emerged. In the design and construction of the terminal, how to increase the non-aeronautical revenue of the terminal has become one of the difficulties and priorities. The commercial vitality is one of the important factors influencing non-aeronautical revenue of the terminal. There is a correlation between passenger flows and commercial space vitality. So it is necessary to analyze the impact of pedestrian flows on commercial space vitality. The commercial space vitality can be evaluated by the vision dwell time on the shop surfaces. This paper focused on the relationship between passenger flows and commercial space vitality at the terminal. We modeled and simulated the domestic mixed-flow hall of Baiyun airport terminal 2 in Massmotion. After the pedestrian 3D vision field simulation, Vision Time Maps were exported to assess the commercial space vitality. After comparing the survey results with simulation results, we can conclude that the mixing of multiple pedestrian flows can improve the commercial space vitality of the airport terminal.

summary	Given the benefits of fine mapping of large urban areas affordably, mobile environmental sensing technologies are becoming increasingly popular to complement the traditional stationary weather and air quality sensing stations. However the reliability and accuracy of low-cost mobile urban technologies is often questioned. This paper presents the design of a fast-response, autonomous and affordable Mobile Urban Sensing Technology (MUST) for the acquisition of high spatial resolution environmental data. Only when accurate neighborhood scale environmental data is affordable and accessible for architects, urban planners and policy makers, can design strategies to enhance urban health be effectively implemented. The results of an experimental air quality sensing campaign developed within Princeton University Campus is presented.

summary	Aviation is in flux, experiencing 5.4% yearly growth over the last two decades. However, with COVID-19 aviation was hard hit. This, along with its contribution to global warming, has led to louder calls to limit its use. This situation emphasizes how urban planners and technologists could contribute to understanding and responding to this change. This paper explores a novel workflow of performing image-based machine learning (ML) on satellite images of over 1,000 world airports that were algorithmically collated using European Space Agency Sentinel2 API. From these, the top 350 United States airports were analyzed with land use parameters extracted around the airport using computer vision, which were mapped against their passenger footfall numbers. The results demonstrate a scalable approach to identify how easy and beneficial it would be for certain airports to expand or contract and how this would impact the surrounding urban environment in terms of pollution and congestion. The generic nature of this workflow makes it possible to potentially extend this method to any large infrastructure and compare and analyze specific features across a large number of images while being able to understand the same feature through time. This is critical in answering key typology-based urban design challenges at a higher level and without needing to perform on-ground studies, which could be expensive and time-consuming.

title	Digital soil: Robotically 3D-printed granular bio-composites
source	International Journal of Architectural Computing vol. 18 - no. 2, 194-211
summary	Organic granular materials offer a valid alternative for non-biodegradable composites widely adopted in building construction and digital fabrication. Despite the need to find alternatives to fuel-based solutions, current material research in architecture mostly supports strategies that favour predictable, durable and homogeneous solutions. Materials such as soil, due to their physical properties and volatile nature, present new challenges and potentials to change the way we manufacture, built and integrate material systems and environmental factors into the design process. This article proposes a novel fabrication framework that combines high-resolution three-dimensional- printed biodegradable materials with a novel robotic-additive manufacturing process for soil structures. Furthermore, the research reflects on concepts such as affordance and tolerance within the field of digital fabrication, especially in regards to bio-materials and robotic fabrication. Soil as a building material has a long tradition. New developments in earth construction show how earthen buildings can create novel, adaptive and sustainable structures. Nevertheless, existing large-scale earthen construction methods can only produce highly simplified shapes with rough geometrical articulations. This research proposes to use a robotic binder-jetting process that creates novel organic bio-composites to overcome such limitations of common earth constructions. In addition, this article shows how biological polymers, such as polysaccharides-based hydrogels, can be used as sustainable, biodegradable binding agents for soil aggregates. This article is divided into four main sections: architecture and affordance; tolerance versus precision; water-based binders; and robotic fabrication parameters. Digital Soil envisions a shift in the design practice and digital fabrication that builds on methods for tolerance handling. In this context, material and geometrical properties such as material porosity, hydraulic conductivity and natural evaporation rate affect the architectural resolution, introducing a design process driven by matter. Digital Soil shows the potential of a fully reversible biodegradable manufacturing process for load-bearing architectural elements, opening up new fields of application for sustainable material systems that can enhance the ecological potential of architectural construction.
