summary	The concrete industry is responsible for 8% of the global CO2 emissions. Therefore, using concrete in more complex and optimized shapes can have a significant benefit to the environment. Digital fabrication with concrete aims to overcome the geometric limitations of standardized formworks and thereby reduce the ecological footprint of the building industry. One of the most significant material economy potentials is in structural slabs because they represent 85% of the weight of multi-story concrete structures. To address this opportunity, Fast Complexity proposes an automated fabrication process for highly optimized slabs with ornamented soffits. The method combines reusable 3D-printed formwork (3DPF) and 3D concrete printing (3DCP). 3DPF uses binder-jetting, a process with submillimetre resolution. A polyester coating is applied to ensure reusability and smooth concrete surfaces otherwise not achievable with 3DCP alone. 3DPF is selectively used only where high-quality finishing is necessary, while all other surfaces are fabricated formwork-free with 3DCP. The 3DCP process was developed interdisciplinary at ETH Zürich and employs a two-component material system consisting of Portland cement mortar and calcium aluminate cement accelerator paste. This fabrication process provides a seamless transition from digital casting to 3DCP in a continuous automated process. Fast Complexity selectively uses two complementary additive manufacturing methods, optimizing the fabrication speed. In this regard, the prototype exhibits two different surface qualities, reflecting the specific resolutions of the two digital processes. 3DCP inherits the fine resolution of the 3DPF strictly for the smooth, visible surfaces of the soffit, for which aesthetics are essential. In contrast, the hidden parts of the slab use the coarse resolution specific to the 3DCP process, not requiring any formwork and implicitly achieving faster fabrication. In the context of an increased interest in construction additive manufacturing, Fast Complexity explicitly addresses the low resolution, lack of geometric freedom, and limited reinforcement options typical to layered extrusion 3DCP, as well as the limited customizability in concrete technology.

title	Methodology for the abstraction and morphological experimentation of nature’s patterns: an application case of morphology research subject in Industrial Design program
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. 217-222
summary	Forms in nature have been emerging in response to different requirements, in a complex and dynamic ecosystem. Architects and designers have usually used references from nature for their projects; in industrial design education, the use of nature’s referents allows to expand the morphological possibilities for product design and systems. In this paper, a methodological proposal for the abstraction and morphological transformation of nature’s patterns is presented, highlighting the advantages of parametric design and additive manufacturing technologies for morphological experimentation, in the context of the first application case of morphology research subject in the Industrial Design program at Universidad Pontificia Bolivariana.

summary	There has been a growing interest in living materials and fabrication processes including the use of bacteria, algae, fungi, and yeast to offer sustainable alternatives to industrial materials synthesis. Microbially induced calcium carbonate precipitation (MICP) is a biomineralization process that has been widely researched to solve engineering problems such as concrete cracking and to strengthen soils. MICP can also be used as an alternative to cement in the fabrication of building materials and, because of the unique process of living fabrication, if we see bacteria as our design collaborators, new types of fabrication and processes may be possible. The process of biomineralization is inherently different from traditional fabrication processes that use casting or molding. Its properties are influenced by the active bacterial processes that are connected to the casting environment. Understanding and working with interrelated factors enables a novel casting approach and the exploration of a range of form types and materials of variable consistencies and structure. We report on an experiment with partial control of mineralization through the design of different experimental vessels to direct and influence the cementation process of sand. In order to capture the form of the calcification in these experiments, we have analyzed the results using three-dimensional imaging and a technique that excavates the most friable material from the cast in stages. The resulting scans are used to reconstruct the cementation timeline. This reveals a hidden fabrication/growth process. These experiments offer a different perspective on form finding in material fabrication.

title	Design for disassembly: Using temporary fabrication for land politics in the Negev
source	International Journal of Architectural Computing vol. 18 - no. 2, 155-173
summary	Political conflicts have increasingly displaced people from their homes, necessitating various forms of temporary structures and housing. However, these shelters are often one-size-fits-all and do not take into account the individual requirements, family structures, or cultural needs of these communities. This article explores how digital fabrication can be used to empower disenfranchised communities to act as their own architects. Because the police demolish the structures in Al Araqib every 3 weeks, the residents have to rebuild their structures, and appropriate architecture as a resistance tool, and not only as a housing solution. This circumstance allows us to develop a structure designed primarily for the condition of rapid disassembly that can additionally be produced with a low-tech setup of a mobile computer numerical control router. Through this case study with the Bedouin village Al Araqib in the Negev Desert, we introduce the term community-specific design, present our methodology for designing and fabricating a temporary structure in collaboration with the community, and outline the logistics for a future mobile infrastructure. Beyond aiding the Bedouin’s fight for justice, our intention as designers, acutely aware of the power of technology and architecture, is to harness both physical and digital tools in an effort to create innovative systems that can be leveraged by unrecognized populations struggling for cultural survival.

title	Dynamic Symbiont - An Interactive Urban Design Method Combining Swarm Intelligence and Human Decisions
doi	https://doi.org/10.52842/conf.ecaade.2020.1.383
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 1, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 383-392
summary	Can a virtual city game be built by both the public and computer-based on real-site data? In the current process of deepening global connectivity, requirements for an effective urban design are no longer limited to functions or aesthetics, but a smart, dynamic complex with multi-interactions of data, group behaviours, and physical space. This paper introduces the logic of swarm intelligence and particle system for proposing a new urban design methodology. The platforms range from simulations that quantify the impact of the disruptive interventions of city activities to communicable collaboration between different users in a UI system, which creates virtual connections between optimized urbanscape and users. In the design system, based on the context data, the computer firstly simulates and optimizes the existing 2D activity joints between the people and analyzed the current spatial connection nodes into certain design rules. Through optimal programming for spatial connection and data iterations, the activity connection structures in the second simulation are abstracted into a set of interactive 3D topographic. The final data-visualization results are presented as a co-building megacity in a virtual construction game. Users can choose the virtual building unit types and intuitively influence the future urbanscape decision through virtual construction.

title	Dynamic Relaxation Simulations of Bacterial Cellulose-based Tissues
doi	https://doi.org/10.52842/conf.ecaade.2020.2.061
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 2, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 61-66
summary	In this paper, a sample of a bacterial cellulose-based tissue is studied in terms of its tectonics by presenting a framework that proposes a transition from digital to physical in terms of design and fabrication. First, sample tissue is digitally modeled and optimized through dynamic relaxation of spring-particle systems by simulating bending behavior; secondly, the tissue is materialized in a form of a biocomposite out of plant cellulose as a fabric out of fiber network for reinforcement, and bacterial cellulose, as the membrane. As the last step, the results are discussed in terms of the deflection, tensile stress lines and bending moment. This framework anticipates a number of methodologies from design and biology, combined with digital fabrication technologies in new ways to change the processes, augment the quality of ideas and outcomes; thus, question the perception of making spaces for living.

title	Gaming Engine as a Tool for Designing Smart, Interactive, Light-Sculpting Systems
source	Herrera, PC, Dreifuss-Serrano, C, Gómez, P, Arris-Calderon, LF, Critical Appropriations - Proceedings of the XXVI Conference of the Iberoamerican Society of Digital Graphics (SIGraDi 2022), Universidad Peruana de Ciencias Aplicadas, Lima, 7-11 November 2022 , pp. 617–628
summary	Even though interactive (Offermans et.al., 2013), adaptive (Viani et.al., 2017), and self-optimizable (Sun et.al., 2020) lighting systems are becoming readily available, designing system automations, and evaluating their impact on user experience significantly challenges designers. In this paper we demonstrate the use of a gaming engine as a platform for designing, simulating, and evaluating autonomous smart lighting behaviors. We establish the Human - Lighting System Interaction Framework, a computational framework for developing a Light Sculpting Engine and for designing occupant-system interactions. Our results include a. a method for combining in real-time lighting IES profiles into a single ‘combined’ profile - b. algorithms that optimize in real-time, lighting configurations - c. direct glare elimination algorithms, and d. system energy use optimization algorithms. Overall, the evolution from designing static building components to designing interactive systems necessitates the reconsideration of methods and tools that allow user experience and system performance to be tuned by design.

summary	Active-Casting explores the use of bespoke computer numerical controlled (CNC) manufactured knits to produce volumetric textile formwork for casting glass-fiber-reinforced concrete (GFRC). As a collaboration between experts in architecture, textile fabrication, and civil engineering, the research investigates multimaterial, functionally graded knit formwork as a fully seamless system to cast concrete. Working with controlled characteristics such as elasticity and stiffness of yarn type and knit structure, the soft textile is conceived as the vessel that defines the performative characteristics of volume, geometry, and surface detail. With only a minimal frame to suspend the volumetric cast, hydrostatic pressure “inflates” the fabric formwork, creating a dynamic form-finding process that eliminates the need for typical molding materials such as wood or foam. While active formfinding processes for CNC knit casting have been explored as an open-face, GFRC-sprayed system, the Active-Casting process produces a finished surface on all faces, embedded with expressions in form and surface detail from the knitted formwork. The precast units using this process reduce the amount of construction waste for formwork production, proposes a more automated fashion for manufacturing the formwork, and produces casts with complex geometries difficult to accomplish with traditional casting methods.

summary	Fabric formwork, known as the casting concrete with flexible fabric molds, frees the nature of the material, which is fluidity; hence, its tectonics. This paper examines the tectonics of concrete and fabric through computational design and analog methods. During this examination, fabrigami technique is used to foresee the intuitive act of concrete within the fabric mold concerning the computational model. Fabrigami use in fabric formwork allows the emergence of a dynamic fabric mold system revealing form variations.

summary	This paper uses the digital software platform to build an intelligent multi-agent system. Through the classification of site elements, the Shanghai North Bund waterfront public space elements are classified into different systems such as transportation hub facilities, catering facilities, shopping facilities and leisure venues. The main population activities in this area are classified into different activities such as youth activities, elderly activities, and family activities through user behavior classification. Finally, the intelligent multi-agent particle swarm is built by the dynamic simulation component of grasshopper, and its individual behavior rules and group interaction rules are adjusted to form the crowd moving particle flow. The particle flow interacts with the classified site elements to derive a distribution pattern of population activity in different systems. Particle flow data information and particle distribution patterns after interactive simulation can be the support for urban design evaluation and optimization.

title	An open-source bio-based material system development for sustainable digital fabrication
doi	https://doi.org/10.52842/conf.ecaade.2020.2.031
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 2, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 31-40
summary	The development of bio-based material systems and their correlation with digital design and fabrication processes is an ever-evolving area of research with a number of experimental investigations. One such direction of investigation is related to the use of mycelium-based materials, which can minimize environmental impact and energy consumption during production, but also can allow alternative sustainable construction approaches to come to the fore. This work proposes an open-source mycelium-based construction material development, emphasizing on three interrelated steps. Firstly, the fungi growth based on Pleurotus ostreatus mycelium. Secondly, the digital production of custom formworks and material casting for uniform growth and building components creation. Finally, the construction technique investigation based on layering and stabilization of components. Through the suggested open-source bio-based material system development, the aim is to provide an alternative approach in construction that involves an ecological material with low environmental impact, interrelated with digital fabrication and assembly processes. This might open new directions of investigation to the wider architecture and construction community, allowing further consideration and possible implementation of mycelium material towards a more sustainable construction.

title	Robotic Fabrication of Sustainable Hybrid Formwork with Clay and Foam for Concrete Casting
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. 377-383
summary	This paper presents a hybrid formwork fabrication method utilizing additive manufacturing with clay on top of curved foam surfaces robotically fabricated with hot wire. The primary focus of this study is to develop a relatively efficient and highly sustainable formwork manufacturing method capable of producing geometrically complex modular concrete building components. The method leverages fluidity and recyclability of clay to produce uniquely shaped, free-form parts of the mold, and reduces overall production time by using foam for shared mold support/enclosure. A Calibration and tool path generating method based on computational modeling to integrate the two systems are also subsequently developed.

summary	We present results on the development of an intelligent and informed SMP prototypes, as proof-of-concept models to assess applicability of thermo-responsive materials in adaptive faÃ§ades. SMP has the intrinsic properties to detect environmental heat changes and react by changing its form into memorized shapes. Among different morphology and deformation behaviours of SMP components, this design-to-fabrication study focuses on design and 3D printing fabrication of prototypes. Additionally, casting was tested to validate the rapid prototyping of additive manufacturing. Furthermore, two different activation systems of SMP were presented to compare mechanisms between a surface-active system and an actuator system.

summary	“Casting on a dump” focuses on finding accessible, low-tech fabrication methodologies that allow for the construction of parametrically designed nonstandard modular cast panels. Such an approach adopts a computational design framework using a single low-tech and low-energy fabrication device to create nonrepetitive volumetric panels cast in situ. The design input for these panels is derived from design preferences and environmental control data. The technique expands upon easy to fabricate and cast methods, targeting less-developed logistical settings worldwide, and thus responding to imminent needs related to climate, available resources, and the economy.

summary	This project aims to continue the correlative study between two fundamental entities of digital architecture: the object and the field. Following periods of experimentations on the ""field"" (materialization of flows of data through animation), the ""field of objects"" (parametricism), the ""object"" (OOO), we investigate the last possible interaction remaining: the ""object-field,"" by merging the formal characteristics of the object with the structural flow of its internal field. This investigation is achieved by exploring the high-resolution features of 3d printing in the design of autonomous architectural objects expressing materiality through topological optimization. The objects are generated by an iterative process of volumetric reduction, resulting in an ensemble of monoliths. Four of them are selected and analyzed through topological optimization in order to extract their internal fields. Next, a series of high-resolution algorithmic systems translate the structural information into 3d printed materiality. Of the four object-fields, one materializes, close to identical, the result of the optimization, giving the keystone to understanding the others. The second one expresses the structural flow through a 1mm voxel system, informed by the optimization, having the effect of stiffening the structure where it is needed and thus generating a new topography on the object. The last two explore the blur that this high-resolution can paradoxically create, with complete integration of the optimal structure in a transparent monolith. This is achieved by a vertex displacement algorithm, and the dissolution of the formal data of the monolith and the structural flows, through the mereological assembly of simple linear elements. For each object-field, a series of drawings was developed using specific algorithmic procedures derived from the peculiarities of their complex geometry. The drawings aim to catalyze coherence throughout the project, where similarities, hitherto kept apart by the multiple materialities, begin to dialogue.

summary	This paper investigates an interactive and adaptive control system for kinetic architectural applications with a distributed sensing and actuation network to control modular fiber-reinforced composite components. The aim of the project was to control the actuation of a foldable lightweight structure to generate programmatic changes. A server parses input commands and geometric feedback from embedded sensors and online data to drive physical actuation and generate a digital twin for real-time monitoring. Physical components are origami-like folding plates of glass and carbon-fiber-reinforced plastic, developed in parallel research. Accelerometer data is analyzed to determine component geometry. A component controller drives actuators to maintain or move towards desired positions. Touch sensors embedded within the material allow direct control, and an online user interface provides high-level kinematic goals to the system. A hierarchical control system parses various inputs and determines actuation based on safety protocols and prioritization algorithms. Development includes hardware and software to enable modular expansion. This research demonstrates strategies for embedded networks in interactive kinematic structures and opens the door for deeper investigations such as artificial intelligence in control algorithms, material computation, as well as real-time modeling and simulation of structural systems.

summary	Due to constant technological developments, society’s priorities and cultural perspectives have changed, requiring a redefinition of experiences in education. In the field of architecture teaching, the transition from CAD (Computer-Aided Design) to the design systems in other digital media, such as the parametric design, can be observed. This article aims to demonstrate two analog-digital experiences in an architecture school. The methodology consisted of dividing the activities into three stages: analog, logical, and digital. The results are described through quantitative and qualitative data acquired in the experiences. The data allowed toreflect on the strategies adopted, lessons learned, and futures challenges.

summary	A growing awareness of architecture's environmental responsibility is encouraging a shift from an industrial age to an ecological one. This shift emphasises a new era of materiality, characterised by a special focus on bio-polymers. The potential of these materials is to address unsustainable modes of resource consumption, and to rebalance our relationship with the natural. However, bio-polymers also challenge current design and manufacturing practices, which rely on highly manufactured and standardized materials. In this paper, we present material experiments and digital design and fabrication methodologies for cellulose-based composites, to create porous biodegradable panels. Cellulose, the most abundant bio-polymer on Earth, has potential for differentiated architectural applications. A key limit is the critical role of additive fabrication methods for larger scale elements, which are a subject of ongoing research. In this paper, we describe how controlling the interdependent relationship between the additive manufacturing process and the material grading enables the manipulation of the material's performance, and the related control aspects including printing parameters such as speed, nozzle diameter, air flow, etc., as well as tool path trajectory. Our design exploration responds to the emerging fabrication methods to achieve different levels of porosity and depth which define the geometry of a panel.

summary	This paper discusses novel methods for and advantages of integrating augmented reality (AR) and photogrammetry in hand clay-sculpting workflows. These techniques permit nontrained users to achieve higher precision during the sculpting process by holographically overlaying instructions from digital 3D source geometry on top of the sculpting material. By employing alternative notational systems in design implementation methods, the research positions itself in a postdigital context aimed at humanizing digital technologies. Throughout history, devices have been developed to increase production, such as Henry Dexter’s 1842 “Apparatus for Sculptors” for marble sculpting. Extrapolating from this, the workflow presented in this paper uses AR to overlay extracted information from 3D models directly onto the sculptor’s field of vision. This information can then become an AR-driven guidance system that assists the sculptor. Using the Microsoft HoloLens, holographic instructions are introduced in the production sequence, connecting the analog sculpture fabrication directly with a digital environment, thus augmenting the craftspeople’s agency. A series of AR-aided sculpting methods were developed and tested in a demonstrator case study project that created a small-scale clay copy of Henry Moore’s Sheep Piece (1971–1972). This paper demonstrates how user-friendly software and hardware tools have lowered the threshold for end users to develop new methods that straightforwardly facilitate and improve their crafts’ effectiveness and agency. This shows that the fusion of computational design technology and AR visualization technology can innovate a specific craft’s design and production workflow, opening the door for further application developments in more architecture-specific fabrication contexts.

summary	The paper describes an architectural design studio for 5th year students at the Department of Architecture of the Aristotle University in Thessaloniki, Greece. The educational objective of the studio is the design of double curved lightweight structures, employing a creative methodology which instrumentalizes the study of nature as a source of inspiration. The objective of the course is to familiarize the students with curves and form-finding (analogue and digital) with the aim to design forms that display structural stability. The paper will highlight the educational gains from a hybrid design methodology which employs both analog (physical) form-finding tools and digital modeling for the design of double curvature surfaces.
