title	Forming Strategies for Robotic Incremental Sheet Forming
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 171-180

summary	Incremental Sheet Forming (ISF) is a flexible forming technology that can process parts without special mould, where-in an indenter moves over the surface of a sheet metal forming a 3D shell through localized deformation. Despite being fundamentally advantageous than stamping for low-volume production, there are many drawbacks to this technique, a major being the low geometrical accuracy of the achieved products, thereby limiting its widespread industrial application. In this paper, flexible support strategies and precise forming compensation have been considered as promising approaches in terms of improving the geometric accuracy in ISF. Four support strategies and a compensation forming method based on FEA and three-dimensional scanning are discussed in detail. Finally, we deploy the technique for the manufacturing of automotive products. The technique is applied to several automotive products of varying topologies and thus form the basis for successful verification of our technique.

summary	This paper investigates new techniques for the production of creative forms in glass by the novel application of robotic incremental sheet forming (ISF) to make steel molds for slumped glass. Also known as single point incremental forming (SPIF), ISF is an industrial fabrication process that uses a robotic arm and end-of-arm tool to press a three-dimensional shape into a sheet material by applying concentrated force along a given toolpath. While precedent exists for architectural assemblies of metal panels formed by ISF, this work proposes an original prototype whereby three-dimensional steel panels are used as formwork for architec- tural glass.

summary	The present study, Nanotectonica SEM-GAN, focuses on two processes for image production, one based in the field of nanotechnology and the other in machine learning: Scanning Electron Microscopy (SEM) and Generative Adversarial Networks (GAN). It establishes commonalities of these routines as they pertain to aesthetics and design methodology, and it explores methods of spatializing and materializing images produced in their interaction. The study of transposing rich image material to three-dimensional geometry and material artifact is considered relevant not only to the particular study at hand, but also to the general problem of image-based machine learning techniques when applied in the spatial design disciplines. A third process, Robotic Incremental Metal Forming (RIMF), advances the aesthetic language of SEM-GAN through the sculptural method of the relief.

title	Programming Twist - Exploring the geometric affordances of aluminum through flexible robotic workflows

summary	This paper explores the geometric affordances of aluminium through flexible robotic workflows. The geometric abundance of the discussed workflows goes beyond what the state-of-the-art industrial metal forming processes offer, and is achieved with simpler means. Two fabrication methodologies, folding and pressing, were explored in order to convert flat, straight panels into twisted, 3-dimensional shapes. The design method for both fabrication strategies was based on physics simulation, where several geometrical constraints force a real time deformation while maintaining the properties of a developable strip. In the first fabrication approach, directionality of the rulings is first engraved into the material while the folding angle is controlled by the robotic setup with two gripping stations. The second fabrication approach refers to a forming process. This has been achieved by installing a wheel cutter on a small workshop hydraulic press and a robot feeding the material into the forming station. The design-to-production pipelines are automated and designed for a small payload robot that allows for a large variety of geometric possibilities. Fabrication challenges of both processes have been documented and assessed, while workflow optimization scenarios and future improvements are proposed in the outlook.

title	Ceramic Incremental Forming–A Rapid Mold-Less Forming Method of Variable Surfaces
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_43
summary	Following architectural practice’s widespread adoption of 3D modelling software, the digital design of free-form surfaces has enabled more heterogeneously organized architectural assemblies. However, fabricating envelope components with double-curved surface geometry have remained a challenge, involving significant machine time and material waste, and great expense to produce. This proof-of-concept project proposes a rapid, low-cost, and minimal-waste approach to forming double curved ceramic components through a novel approach to Ceramic Incremental Forming (CIF), using a 6-axis industrial robot, a passive flexible mold, and a custom ball-rolling tool. The approach is comparable to Single Point Incremental Forming (SPIF) that is used for forming complex shapes with metal sheets. This method promises to achieve high-quality, ceramic building envelope components, while eliminating the need to build proprietary molds for each shape and reducing the waste in the forming process. Compared with other architectural mold-less forming methods such as clay 3D printing, the approach is more time and material efficient, while being able to achieve similar levels of complexity. Thus, CIF may offer potential for further development and industrial applications.

title	Precision Factors in Modelling of Relief Patterns on Thin Aluminum Plates - Learning from making process
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 111–120
doi	https://doi.org/10.52842/conf.ecaade.2022.1.111
summary	Surface coordinates on thin metal sheets constantly change during the engraving, and the digital model is not truly compatible with the physical engraving process because of the ignorance of the relationship between the hand movements with the tooltip and material in digital fabrication. Hence, this research creates experiments to learn from the physicality of the making process for precision factors in modeling relief patterns on thin aluminum plates. It questions the identification and elimination of precision problems of material and behavior in the production process of relief with a robotic arm. It aims to determine the relationships among materials, tools, and geometry in robotic manufacturing. UArm Swift Pro as a tool performs the task concerning speed, the surface of the tooltip, material thickness, drawing, and engraving modes. Created 3D geometries on aluminum surfaces are compared according to the change in distance between initial and target points, curvature, and radius of the target geometry.

summary	InterspeciesForms hybridizes mycelia’s agency of growth with architectural de-sign intention in the generation of novel, crossbred designed outcomes. In order to establish a direct dialogue between architectural and mycelia agencies, robotic feedback systems are implemented to extract data from the physical and feed it in-to the digital realm. Initiating this cyclic feedback system, mycelia growth is scanned in order to computationally visualize its entangled network and agency. Based on the logic of stigmergy, computational agents trace around the organisms patterns of growth, forming entangled and complex networks. Through this unification of biological growth and computational agencies, non-indexical crossbred outcomes begin to emerge. Bringing this hybridized computational form back into the physical realm, form is 3D printed with a customized mixture of mycelium and agricultural waste. Once the geometry has been extruded, the robot, patiently waits for the mycelia to grow and react to the living extrusions. The architect then responds with a countermove by scanning this new growth and continuing the cyclic feedback system between nature-machine and architect. This procedure demonstrates form emerging in real time according to the co-creational design process and dialogue between architectural and mycelia agencies.

title	Kerf Guided Glulam - A novel way of creating curved glulam beams
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 85–90
doi	https://doi.org/10.52842/conf.ecaade.2022.1.085
summary	This paper proposes a novel way of producing curved glulam timber elements where the formwork is integrated into a glulam beam. The method proposed accomplishes this by placing kerf cuts on a timber profile that gets bent and then encased in a wood laminate, forming the glulam beam. The kerf placement allows the beam to be asymmetrically curved. The optimal placement for the kerf cuts is found by feeding an initial goal curve to a form-finding definition that subdivides it and places markers where cuts need to be made while manipulating the beam geometry, ensuring that it matches the initial input curve. The benefit of this method is that it is not reliant on large-scale glulam setups but can be fabricated with basic wood workshop tools in conjunction with a 5-axis CNC mill. The simplified production process enables smaller manufacturers and designers to produce dynamic wooden structures while saving on materials and labour that would have gone into producing formwork that eventually gets discarded.

title	Decentralised Solar Economy: Unattended and Smart Solar Energy Urban System (UnSSEUS)

summary	Planners often go out of the city when planting large-scale solar farms due to requirements for huge, flat surface areas. This reduces urban proximity to renewable energy sources, causing dissipation during energy transfer and a waste in solar energy unused within urban areas. This paper aims at understanding the prospect and challenges in transforming buildings from passively consuming energy to actively generating energy for cities. As every building has a different renewable energy capacity, how may we re-distribute power amongst a network of users, forming a socio-economy around distributed power generation? This paper first presents its theoretical approach learning from fields of biology and information theory as a source of inspiration for its design methodology. It then presents a context study of Hong Kong and its Feed-in Tariff scheme that incentivizes distributed power generation, and identifies the challenges. Afterwards, it defines ‚Unattended and Smart Solar Energy Urban System‚ and proposes the parameters which the system should comprehend on its dashboard for demand-side management of energy. Finally, preliminary results of using a sudoku algorithm in distributing time and pricing factors of energy exchange are presented. This on-going research project aims at SDG goals 7 and 11.

title	Mapping Plant Microclimates on Building Envelope Using Environmental Analysis Tools

doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_13
summary	Can we build our cities not only for humans but also for all living systems? How can we consider other species occupants of the built environment? Planning cities as an element of the natural domain can reshape our relationship with nature and help redefine sustainability in architecture. Although current design strategies of reducing energy use does not rectify past/continuing im-balances in the natural environment. Landscape architect John Tillman Lyle expanded the regenerative design concept based on a range of ecological concepts. The environment's complexity, and the urge to use resources smartly, encouraged him to think about architecture and the environment as a whole system. John Lyle's regenerative design strategies scaffold a conceptual framework of treating the building as part of the landscape. Environmental tools such as Ladybug can map out the different conditions surrounding the building's envelope. This information can assist in selecting and populating a building façade with suitable plant species. The framework presents the building as a feature in the landscape, creating microclimatic conditions for various plant habitats. This conceptual workflow has the potential to become a tool to include regenerative principles in the urban context.

title	Robotic 3D Printing of Mineral Foam for a Lightweight Composite Concrete Slab
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 61-70
doi	https://doi.org/10.52842/conf.caadria.2022.2.061
summary	This paper presents the design and fabrication of a lightweight composite concrete slab prototype using 3D printing (3DP) of mineral foams. Conventionally, concrete slabs are standardized monolithic elements that are responsible for a large share of used materials and dead weight in concrete framed buildings. Optimized slab designs require less material at the expense of increasing the formwork complexity, required labour, and costs. To address these challenges, foam 3D printing (F3DP) can be used in construction as demonstrated in previous studies for lightweight facade elements. The work in this paper expands this research and uses F3DP to fabricate the freeform stay-in-place formwork components for a material-efficient lightweight ribbed concrete slab with a footprint of 2 x 1.3 m. For this advancement in scale, the robotic fabrication and material processing setup is refined and computational design strategies for the generation of advanced toolpaths developed. The presented composite of hardened mineral foam and fibre-reinforced ultra-high-performance concrete shows how custom geometries can be efficiently fabricated for geometrically complex formwork. The prototype demonstrates that optimized slabs could save up to 72% of total concrete volume and 70% weight. The discussion of results and challenges in this study provides a valuable outlook on the viability of this novel fabrication technique to foster a sustainable and resourceful future construction culture.

title	Fabrication of Reinforced 3D Concrete Printing Formwork
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_44
summary	In recent years, the emerging 3D printing concrete technology has been proved to be an effective and intelligent strategy compared with conventional casting concrete construction. Due to the principle of additive manufacturing strategy, this concrete extrusion technique creates great opportunities for designing freeform geometries for surface decoration since this material has a promising performance of high compressive strength, low deformation, and excellent durability. However, the structure behavior is usually questioned, defined by the thickness and printing path. At the same time, the experiments for using 3D printing elements for structural and functional parts are still insufficient. Little investigation has been made into developing reinforcement strategies compatible with 3D printing concrete. In fact, conventional formwork and easy-to-install reinforcement support structures have various advantages in terms of labor costs but can hardly be reused. Thus, using 3D concrete printing as formwork for projects in different scales is an effective solution in the mass customized prefabrication era. Considering large-scale projects, the demand to provide concrete formwork with a proper reinforcement strategy for better toughness, flexibility, and strength is necessary. In this paper, we proposed different off-site reinforced 3D printing concrete strategies and evaluated them from time and material cost, deviation, and accessibility of fabrication.

doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_6
summary	Co-creation and real-time collaboration have always been an integral potential of digital design methodologies and have been accelerated by the rapid digitalization of teaching due to current societal developments. This paper discusses the prototype of a real-time multiplayer building platform as a video game developed for a first-year design studio impacted by pandemic-related teaching restrictions. The aim was to develop a methodology that enables first-year students to meet peers, build models collaboratively, and teach implicit design knowledge such as aesthetics and formal analysis while allowing individual creativity within the populous class. Through a combination of a step-by-step iterative design system and a real-time decentralized multi-player platform, students can work collaboratively on common digital designs. The design method is based upon building units and individualized strategies of aggregation and differentiation that are built up into larger structures. Special focus is paid to how new online platforms created for architecture education can migrate the advantages of physical intuitive design methods to a digital setting and eventually fill the gap of lacking implicit knowledge pedagogies.

summary	In this paper we present strategies and workflows for cellulose-based biopolymer 3D printing. We propose a digital design framework informed by the fabrication system and guided through human design input. The workflow stabilizes the material at the scale of the toolpath, the component, and the wall assembly, by integrating joinery and cross-bracing together with the component geometry. We showcase the feasibility of a large-scale dry-assembly of 3D printed biopolymer components. The demonstrator wall allows us to evaluate our workflows and discuss the challenges and implication of bringing biomaterials in our built environment.

title	Evaluation Process of Urban Spatial Quality and Utility Trade-Off for Post-COVID Working Preferences
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_19
summary	The formation of cities, and the relocation of workers to densely populated areas reflect a spatial equilibrium, in which the higher real consumption levels of urban areas are offset by lower non-monetary amenities [1]. However, as the society progress toward a post-COVID stage, the prevailing decentralized delivery systems and location-based services, the growing trend of working from home, with citizens’ shifting preference of de-appreciating densities and gathering, have not only changed the possible spatial distribution of opportunities, resources, consumption and amenities, but also transformed people’s preference regarding desirable urban spatial qualities, value of amenities, and working opportunities [2, 3]. This research presents a systematic method to evaluate the perceived trade-off between urban spatial qualities and urban utilities such as amenities, transportation, and monetary opportunities by urban residence in the post-COVID society. The outcome of the research will become a valid tool to drive and evaluate urban design strategies based on the potential self-organization of work-life patterns and social profiles in the designated neighbourhood. To evaluate the subjective perception of the urban residence, the study started with a comparative survey by asking residence to compare two randomly selected urban contexts in a data base of 398 contexts sampled across Hong Kong and state their living preference under the presumption of following scenarios: 1. working from home; 2. working in city centre offices. Core information influencing the spatial equilibrium are provided in the comparable urban context such as street views, housing price, housing space, travel time to city centre, adjacency to public transport and amenities, etc. Each context is given a preference score calculated with Microsoft TrueSkill Bayesian ranking algorithm [4] based on the comparison survey of two scenarios. The 398 contexts are further analysed via GIS and image processing, to be deconstructed into numerical values describing main features for each of the context that influence urban design strategies such as composition of spatial features, amenity allocation, adjacency to city centre and public transportations. Machine learning models are trained with the numerical values of urban features as input and two preference scores for the two working scenarios as the output. The correlation heat maps are used to identify main urban features and its p-value that influence residence’s preference under two working scenarios in post–COVID era. The same model could also be applied to inform the direction of urban design strategies to construct a sustainable community for each type of working population and validate the design strategies via predicting its competitiveness in attracting residence and developing target industries.

title	Introducing Bespoke Properties to Slip-Cast Elements
source	ACADIA 2022: Hybrids and Haecceities [Proceedings of the 42nd Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-8-1]. University of Pennsylvania Stuart Weitzman School of Design. 27-29 October 2022. edited by M. Akbarzadeh, D. Aviv, H. Jamelle, and R. Stuart-Smith. 244-255.
summary	This research explores a novel technique for creating bespoke, slip-cast artifacts through the use of 6-axis robotic motion. By incrementally injecting different amounts of colored slip into the mold while it is rotated, we are able to achieve variable color, pattern, and structure. Because of the highly precise nature of the robotic motion, this variation can be repeated with a high degree of accuracy. In addition, the incremental injection of slip also allows us to achieve a full cast with a minimal amount of slip, removing the draining process of traditional slip casting entirely. The level of control this process might give a designer is explored through a series of tetrahedral components that demonstrate the types of marbling that can be achieved.

title	Hexagonal Responsive Facade Prototype in Responding Sunlight

doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_36
summary	This paper discusses an architectural responsive façade system using hexagonal parametric forms and kinetic mechanism which responds sunlight. Its purposes are to buffer excessive sun exposure that goes through interior space and maximize the covering area with an incremental rotational joint system. The study aims to explore responsive façade system as second skin for architectural building, focusing on design, mechanism, and fabrication processes. The prototype consists of three parts: the hexagonal modules where the membranes and its frames are compacted; a series of levers to synchronize the movement of opening the membranes from each module; and a structural framework to hold each module as united kinetic façade system. As a preliminary prototype, the system can potentially be applied to several types of existing buildings and easily installed in various sizes and configuration. This kinetic mechanism can decrease sun radiation up to 50% than unprotected window façade.

summary	Compared to the take-make-waste-oriented linear economy model, the circular model has been studied since the 1980s. Due to consumption-oriented lifestyles along with having a tendency of considering waste materials as trash, studies on sustainable materials management (SMM) have remained at a theoretical level or created temporary and limited impacts. To ensure SMM supports The European Green Deal, there is a necessity of developing top-down and bottom-up strategies simultaneously, which can be metaphorized as digging a tunnel from two different directions to meet in the middle of a mountain. In parallel with the New European Bauhaus concept, this research aims to create a case study for boosting bottom-up and data-driven methodologies to produce short-loop products made of bio-based biocomposite materials from local food & organic wastes. The Architecture departments of two universities from different countries collaborated to practice these design democratization methodologies using data transfer paths. The 3D printable models, firmware code, and detailed explanation of working with a customized 3D printer paste extruder were shared using online tools. Accordingly, the bio-based biocomposite recipe from eggshell, xanthan gum, and citric acid, which can be provided from local shops, food & organic wastes, was investigated concurrently to enhance its printability feature for generating interior design elements such as a vase or vertical gardening unit. While sharing each step from open-source platforms with adding snapshots and videos allows further development between two universities, it also makes room for other researchers/makers/designers to replicate the process/product. By combining modern manufacturing and traditional crafting methods with materials produced with DIY techniques from local resources, and using global data transfer platforms to transfer data instead of products themselves, this research seeks to unlock the value of co-creative design practices for SMM.

summary	3D Concrete Printing (3DCP) currently dominates the scene of digital fabrication with concrete. 3DCP can be utilized on-site or in prefabrication setups. While prefabrication with 3DCP allows for more complex construction elements, it also requires the design for connections and assembly. In the context of prefabrication using 3DCP, this paper illustrates the state of research in the design, construction, and assembly of 3D printed components. It proposes segmentation and fabrication strategies to produce horizontal and vertical structural members of a column-slab building system following the typology of mushroom slabs.
