title	Computational co-design of fibrous architecture
doi	https://doi.org/https://doi.org/10.1007/s44223-022-00004-x

summary	Fibrous architecture constitutes an alternative approach to conventional building systems and established construction methods. It shows the potential to converge architectural concerns such as spatial expression and structural elegance, with urgently required resource effectiveness and material efficiency, in a genuinely computational approach. Fundamental characteristics of fibre composite are shared with fibre structures in the natural world, enabling the transfer of design principles and providing a vast repertoire of inspiration. Robotic fabrication based on coreless filament winding, a technique to deposit resin impregnated fibre filaments with only minimal formwork, as well as integrative computational design methods are imperative to the development of complex fibrous building systems. Two projects, the BUGA Fibre Pavilion as an example for long-span structures, and Maison Fibre as an example of multi-storey architecture, showcase the application of those techniques in an architectural context and highlight areas of further research opportunities. The highly interrelated aesthetic, structural and fabrication characteristics of fibre nets are difficult to understand and go beyond a designer’s comprehension and intuition. An AI powered, self-learning agent system aims to extend and thoroughly explore the design space of fibre structures to unlock the full design potential coreless filament winding offers. In order to ensure feedback between all relevant design and performance criteria and enable interdisciplinary convergence, these novel design methods are embedded in a larger co-design framework. It formalizes the interaction of involved interdisciplinary domains and allows for interactive collaboration based on a central data model, serving as a base for design optimisation and exploration. To further advance research on fibre composites in architecture, bio-based materials are considered, continuing the journey of discovery of fibrous architecture to fundamentally rethinking design and construction towards a novel, computational material culture in architecture.

title	Activating Co-Creation Methodologies of 3D Printing with Biocomposites Developed from Local Organic Wastes

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	Understanding memory as the faculty by which a system stores and remembers information from the past to a new purpose with shapes that are emerging as “collective designs"(a repository of built information), this research works with the demonstration in how CA can generate a trace of its existence as memory based on the activation and deactivation of the discrete system in which grows, like a footprint in the affected area of intervention, improving a “stigmergic operation” in the field, conditioning the following steps in the collaborative growing of this basal structure. Based on sets of digital experiments, a set of CA using Langton Ants generates different solutions based on the activation and deactivation of rules according to information coming from patterns, creating spatial solutions that deal with built memory three-dimensional emergent structures.

title	Democratizing Stereotomic Construction through AR Technologies - A reusable mold methodology to the production of customized voussoirs using HoloLens
doi	https://doi.org/10.52842/conf.ecaade.2022.1.225
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. 225–232
summary	Mass customizing of building components allows new conditions to explore aesthetic and sustainability in architecture. However, such possibilities tend to require the use of expensive and heavy digital fabrication machinery, which is seldomly available in most regions on the planet. In this context, this paper presents a research in progress that explores Augmented Reality (AR) to support craft production of customized stereotomic components. As a portable technology, the work examines the potential of AR to materialize design solutions that are geometrically complex and variable. Considering the current research on augmented fabrication processes, this work contributes to producing variable building components for stereotomic construction with a focus on earth-based materials. Extending the findings of a recently completed PhD thesis, the work replaces the use of a robot with the HoloLens glasses and Fologram application to produce low- cost and reusable molds. This augmented fabrication setup allows the human control of the production of variable molds, ready for casting and assembly of stereotomic components. This work addresses several of the NEB and UN SDGs goals.

summary	This research explores the constructive and expressive capabilities of stigmergic-based creasing patterns integrating structural and ornamental conditions in fibre-composite surface tectonics, generated by the reciprocal influence of multi-agent systems and Non- Linear Time History (NLHT) dynamic structural simulation. Building upon precedents on the use of agent bodies and behavioural tectonics such as the work of Roland Snooks, our approach employs NLTH simulation for the dynamical assessment of the structural failure modes to provide information for agents behaviour and a comparative assessment of the bodies pattern contribution. Considering the obtained results, insights gained on the structural behaviour of multi-agent composite surface tectonics while attempting to explore its embedded architectural, morphological and expressive qualities are discussed.

title	The Digital Touch - Towards novel modeling frameworks for robotically-enhanced marble sculpting
doi	https://doi.org/10.52842/conf.ecaade.2022.1.037
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. 37–46
summary	In this paper, two case studies on digital modeling for robotically-enabled marble carving are presented. In the first one, an interactive, gesture-based modeling framework was developed to sculpt a large, undulating and ultra-thin marble surface. On the second one, an integrated 3D-scanning-to-milling solution was created, in order to groove a superficial pattern on the surface of a discarded marble boulder. The cases evidence the power of tangible interaction to serve as input to novel digitally-aided marble sculpting processes, and the capacity of integrated generative design workflows to create consistent solutions to variable conditions, in this case, with a particular focus on sustainability and reclaiming of scrap materials.

title	Extrusion-Based 3d Printing for Recyclable Gypsum

summary	Gypsum is one of the most commonly used construction materials in cladding and non-load-bearing decoration. Recently, 3D printing technology has been involved in creating complex geometry. The particle-based method is the principal approach in 3D gypsum printing. However, the complex device and limited printable range limit the massive production of large-scale building components. This paper proposed a novel extrusion-based gypsum printing method and corresponding robotic fabrication workflow. First, several experiments are conducted to analyze the effect of different admixtures (retarder, activation agent, and accelerator) on the material setting properties. Second, a set-on-demand gypsum-based material is proposed by actively controlling multiple admixtures. Then, a process parameter-based robotic fabrication workflow is proposed, and a set of extrusion- based 3D gypsum printing equipment is built. center864108000A curved gypsum panel sample is printed as experimental verification. By comparing to the particle-based method, The test sample shows that the extrusion-based method can effectively improve the production efficiency and reduce the production cost. Therefore, the proposed method gives a relatively efficient and cost-effective way to produce recyclable gypsum material massively.

title	Towards a Digital Practice of Historical Stone Carvings
doi	https://doi.org/10.52842/conf.ecaade.2022.2.227

summary	Local traditional crafts in various parts of the world are being transformed by digitalization in tandem with broader social and economic changes. Mardin, a historical and cultural hub in southeast Anatolia, presents an exemplary case with its stone architecture. Whereas the number of skilled craftsmen is diminishing, digital fabrication ateliers are increasingly in demand in the city and rising in number. Training programs have already started integrating CNC milling-based techniques. However, despite the growing interest in adapting computational processes, how the craft knowledge is documented and conveyed to multiple actors for maintaining and even increasing the quality of workmanship is yet to be explored. We present a novel way to document carving procedures and to create an inventory of the 3D motifs using cross-sections as complements to front views. The research engages end-user participants of different backgrounds, such as stone cutting technologies and architecture, with little or no practical knowledge of digital manufacturing. The work focuses on a selection of motifs from the Syriac stone carving heritage in Mardin, the documentation of which is very limited. The proposed workflow begins with recording the surface depth and the variations in the cross-section using digital scans. In the second stage, we consider the potential subtractive transformations that result in the final form and reconstruct them as milling operations with a parametric and procedural modeling approach. Various milling processes are derived by relating the shapes to the available cutting tools and materials. The study contributes to creating the inventory of an engraving culture that has lasted for hundreds of years while developing a generally applicable and transferable knowledge base to increase its sharing and dissemination in the age of digitally supported production.

title	Moisture-Harvesting Lizard Skins as an Inspiration for Performative Building Envelopes in Arid Climates
source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 515-528
summary	Research on shape-shifting adaptive architectural skins has recently focused on bio-inspired programmable materials. Only a few studies however examine the microstructure of living organisms, especially in terms of morphological adaptation in harsh climatic conditions. This paper explores the microstructure of moisture-harvesting lizard skins, specifically the Trapelus species of the Agamidae family in North-East Africa, as an inspiration for programmable materials in adaptive building skins in the arid climate of Egypt. The paper investigates the ability to improve the durability and morphological capabilities of programmable materials based on surface formation, utilizing digital fabrication techniques. A series of physical experiments were conducted on different samples of 3D printed wood filament under several humidity conditions, as a single layer, with textured patterns, and with the addition of potassium chloride as a moisture-harvesting chemical composite. The paper concluded that materials composed of textured patterns and moisture-harvesting chemical composites exhibited the highest moisture retention, therefore leading to advantages in its use in adaptive building skins in arid climates, through a wide variety of design possibilities for performative building envelopes.

title	Design Intents Disentanglement: A Multimodal Approach for Grounding Design Attributes in Objects
doi	https://doi.org/10.52842/conf.caadria.2022.1.333
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. 333-342
summary	Language is ambiguous; many terms and expressions convey the same idea. This is especially true in design fields, where conceptual ideas are generally described by high-level, qualitative attributes, called design intents. Words such as "organic", sequences like "this chair is a mixture between Japanese aesthetics and Scandinavian design" or more complex structures such as "we made the furniture layering materials like a bird weaving its nest‚ represent design intents. Furthermore, most design intents do not have unique visual representations, and are highly entangled within the design artifact, leading to complex relationships between language and images. This paper examines an alternative design scenario based on everyday natural language used by designers, where inputs such as a minimal and sleek looking chair are visually inferred by algorithms that have previously learned complex associations between designs and intents‚vision and language, respectively. We propose a multimodal sequence-to-sequence model which takes in design images and their corresponding descriptions and outputs a probability distribution over regions of the images in which design attributes are grounded. Expectedly, our model can reason and ground objective descriptors such as black or curved. Surprisingly, our model can reason about and ground more complex subjective attributes such as rippled or free, suggesting potential regions where the design object might register such vague descriptions.

summary	The expansion of urbanization leads to significant changes in land use, consequently affecting carbon storage. This research aims to investigate the carbon loss due to land use alterations and proposes strategies for mitigation. Utilizing existing land use data from 2017 and 2022, along with simulated data for 2025 generated by an ANN model and Cellular Automata, we identified changes in land use. These changes were then correlated with variations in carbon storage, both gains and losses. Our findings reveal a significant loss of 36,859 metric tons of carbon storage from 2017 to 2022. The projection for 2025 estimates a further reduction, reaching a total loss of 83,409 metric tons. By employing the LISA method, we identified that low-carbon storage zones are concentrated in the southeast region of the research site. By overlaying these zones with areas of carbon storage loss, we pinpointed regions severely affected by carbon depletion. Consequently, we propose that mitigation strategies should be imperatively implemented in these identified areas to counteract the trend of carbon storage loss. This approach offers urban planners a solution to identify areas experiencing carbon storage decline. Moreover, our research methodology provides a novel framework for scholars studying similar carbon issues.

summary	Inflatable structures made of flat film materials have an advantage of low cost, lightweight and rapid deployment, but the variation of their forms is relatively limited, and it is a challenge to produce pneumatic deformations. This paper proposes a designing and manufacturing process of inflatable structures which are made of flat film materials and are able to perform dynamic movements. The process includes steps in which a target 3D surface is produced through programmed 2D paths heat-sealed on flat films of different thickness, leading to a structure composed of air chambers. A parametric modelling procedure and associated principles are developed for the relationship between the forms of a flat-film-based inflatable structure and the heat sealing patterns on the film. A system of double-layer air chambers was designed to control the direction of bending movements. In addition, the form variation of a designed inflatable structure can be achieved by a parametric design process described in this paper.

summary	Reinforced concrete has been one of the essential materials for modern architecture for the last hundred years. Its use is entirely global, having been adopted by all cultures and styles since its invention in the late 19th century. Although its value is excellent due to its low cost, durability and adaptability, its environmental impact is significant, being, in fact, one of the most polluting industries in the world (Babor et al. 2009). This experimental project will research a more sustainable use of concrete, exploring a new form of reusable concrete formwork that will ideally reduce the CO2 footprint by removing wood waste in the casting process and replacing it with adaptable metal components. The modular part-based system for the concrete casting also attempts to simplify one of the current complexities for concrete construction, the Skilled-Labour shortage. (Yusoff et al. 2021). To mitigate this problem, the project also proposes using an Augmented Assembly logic for the casting parts to guide the ensemble and dismantle the formwork through an optimised algorithmic logic. The use of Augmented Reality as a replacement for traditional paper instructions will facilitate access to more workers to this construction art and potentially improve access to optimised use of concrete in developing communities with restricted building technological resources.

summary	We present a synergetic combination of two previously separate process technologies to create novel lightweight structures. 3D textiles and 3D printing. We will outline the development of a novel material system that consisted of flexible and foldable 3D textiles that are combined with stiff, linear 3D printed materials. Our aim is to produce material-reduced lightweight elements for building applications with an extended functionality and recyclability. Within an ongoing research project (6dTEX), we explore a mono-material system, which uses the same base materials for both the filament for 3D printing and the yarn of the fabrication of the 3D textiles. Based on preliminary 3D printing tests on flat textiles key process parameters were identified. Expertise has been established for 3D printing on textiles as well as for using printable recycled polyester materials (PES textile and PETG filament. Lastly for 3D printing on non-combustible material (alkali-resistant (AR) glass textiles and for 3D concrete printing (3DCP). The described process- knowledge facilitates textile architectures with an extended vocabulary, ranging from flat to single curved and folded topologies. Whereas the foundations are laid in the research project on a meso scale, we also extended our explorations into an architectural macro scale. For this, we used a more speculative design-build studio that was based on a more loose combination of 3D textiles and 3D printed elements. Lastly, we will discuss, how this first architectural application beneficially informed the research project.

title	Bio-digital Sand Logics: Dune Sand Material and Computational Design
doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_35
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
summary	This paper discusses the creation of a new sand-based material, performative testing, and the computational logic involved in the design of a prototypical architectural system. Dune sand is known to be an unstable material compared to river or marine sand and as a result it is not normally used for construction. Because of this, desert regions have grown a reliance upon imported materials creating massive sustainability issues due to large scale global shipping, importation and resource extraction. This research indicates there is a viable opportunity to leverage dune sand as an ongoing line of inquiry for material science and design in local desert regions. It establishes that there is very little architectural research being done in this particular area. The methodology begins with experiments in bio-material using dune sand as a compound, and then establishes a construction system based upon a manifold of experiments. Along with material investigations, the process uses a Scientific Testing Method (STM) and Hypothesis in Action (HIA) as part of the testing methodology.

summary	This paper examines how the central contributions of the computational design field can be understood as central steppingstones into an age of sustainability to engage with new renewable, regenerative and restorative material systems. By taking departure in the conceptualisation of an extended digital chain by which architecture can address fabrication at the low scales of the material, this paper asks how these methodological innovations can be transferred to new questions arising from a bio-based material paradigm. The paper outlines the three central contributions of the computational design field: advanced information modelling, functional grading and integrated sensing, and suggests how these can be extended to allow new means of instrumentation for bio-based materials characterised by the heterogeneous, the behaving and the living.

title	Robotically Printed Seaweed as a Biomaterial within Architecture and Design
doi	https://doi.org/10.52842/conf.caadria.2022.2.303

summary	This research aims to develop and understand the impact of seaweed as a bio-based material within architecture and design. The research is influenced by current global challenges, outlined by the Sustainable Development Goals (SDG), such as carbon drawdown, the problem of material waste, and the need to create more sustainable manufacturing processes. Seaweed is an organic biomass that does not require land, fresh water or fertilisers to grow, and growing it can reduce the effects of global warming as it sequesters large amounts of carbon dioxide. In turn, it can be harvested and used for a range of products including food, biofuel, fertiliser and bioplastic. The research focuses on the development of an organic, water-based biocomposite material made from sodium alginate, a derivative of brown seaweed, combined with cellulose powder, vegetable glycerine, and kelp powder. A set of methodical experiments were conducted and studied, with the aim of creating a novel material which can adapt to its surrounding environment and can degrade naturally. By creating and fabricating using renewable resources, one can create novel materials that are carbon neutral and contribute to a natural resource cycle. Ultimately, the material decays and returns to the earth, for the purpose of remediating soils and replenishing growth.

title	Calibrating a Formfinding Algorithm for Simulation of Tensioned Knitted Textile Architectural Models
doi	https://doi.org/10.52842/conf.caadria.2022.1.111
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. 111-120
summary	This paper presents an optimization-based calibration process for tuning a digital formfinding algorithm used with knitted textile materials in architectural tension structures. 3D scanning and computational optimization are employed to accurately approximate a physical model in a digital workflow that can be used to establish model settings for future exploration within a knit geometric typology. Several aspects of the process are investigated, including different optimization algorithms and various approaches to data extraction. The goal is to determine the appropriate optimization method and data extraction, as well as automate the process of adjusting formfinding settings related to the length of the meshes associated with the knitted textile behavior. The calibration process comprises three steps: extract data from a 3D scanned model; determine the bounds of formfinding settings; and define optimization variables, constraints, and objectives to run the optimization process. Knitted textiles made of natural yarns are organic materials and when used at the industrial level can satisfy DSG 9 factors to promote sustainable industrialization and foster innovation in building construction through developing sustainable architectural systems. The main contributions of this paper are calibrated digital models of knitted materials and a comparison of the most effective algorithms and model settings, which are a starting point to apply this process to a wider range of knit geometries. These models enhance the implementation and further development of novel architectural knitted systems.
