title Sensory material architectures: Concepts and methodologies for spatial tectonics and tactile responsivity in knitted textile hybrid structures
source International Journal of Architectural Computing vol. 14 - no. 1, 63-82
summary As the knowledge of material computation advances, continuing the seamless integration of design and fabrication, questions beyond materialization can be addressed with a focus on sensing, feedback, and engagement as critical factors of design exploration. This article will discuss a series of prototypes, design methodologies, and technologies that articulate a textile’s micro-architecture, at the scale of fibers and stitches, to instrumentalize simultaneous structural, spatial, and sensory-responsive qualities. The progression of research displays an ever-deepening instrumentalization of fiber structure and its implications to form definition and responsivity, in creating form- and bending-active structures. The research results in a more refined definition of material behavior as the innate phenomena which emerge at the moment of textile fabrication. Ultimately, the architecture, in its materiality and physical, visual, and auditory responsivity, is designed to address specific challenges for children in filtering multiple sensory inputs, an underlying factor of autism spectrum disorder.

summary Textiles are widely used in architecture for tensile structures, as they are lightweight and can easily span large distances. These structures typically require an external framework for a support. Inflatable structures are self-supporting but are limited to relatively simple forms or require complex and predetermined cut patterns. The development of an adaptive and programmable textile system with an integrative method for pneumatic activation would create a novel self-supporting structure with high degree of design and architectural potential. This creates a highly integrative hybrid system where the generic pneumatic membranes are constrained by the differentiated knitted textile skin that is stretched in several directions under air pressure. This allows for an innovative, lightweight, easily transportable design, where the preprogrammed knitting pattern defines the structure, geometry and formation, activated under pneumatic pressure.

title Knit Architecture: Exploration of Hybrid Textile Composites Through the Activation of Integrated Material Behavior
doi https://doi.org/10.52842/conf.acadia.2016.254
source ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 254-259
summary The hybrid system in textile composites refers to the structural logic defined by Heino Engel, which describes a system that integrates multiple structural behaviors to achieve an equilibrium state (Engel 2007). This research explores a material system that can demonstrate a hybrid material behavior defined by the differentiated tensile and bending-active forces in a single, seamless knitted composite material. These behaviors were installed during the materialization phase and activated during the composite formation process. Here, the material formation involves two interdependent processes: 1) development of the knitted textile with integrated tensile and reinforced materials and 2) development of the composite by applying pre-stress and vacuuming the localized area with reinforcements in a consistent resin-based matrix. The flat bed industrial weft knitting machine has been utilized to develop the knitted textile component of the system with a controlled knit structure. This enables us to control the material types, densities, and cross sections with integrated multiple layers/ribs and thus, the performance of the textile at the scale of fiber structure. Both of these aspects were researched in parallel, using physical and computational methods informed and shaped by the potentials and constraints of each other. A series of studies has been utilized to develop small-scale prototypes that depict the potential of the hybrid textile composite as the generator of complex form and bending active structures. Ultimately, it indicates the possibilities of hybrid textile composite materials as self-structuring lightweight components that can perform as highly articulated and differentiated seamless architectural elements that are capable of transforming the perception of light, space, and touch.

title Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
doi https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
source Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
summary A research team at Florida International University Robotics and Digital Fabrication Lab has developed a novel method for 3d-printing curved open grid core sandwich structures using a thermoplastic extruder mounted on a robotic arm. This print-on-print additive manufacturing (AM) method relies on the 3d modeling software Rhinoceros and its parametric software plugin Grasshopper with Kuka-Parametric Robotic Control (Kuka-PRC) to convert NURBS surfaces into multi-bias additive manufacturing (MBAM) toolpaths. While several high-profile projects including the University of Stuttgart ICD/ITKE Research Pavilions 2014–15 and 2016–17, ETH-Digital Building Technologies project Levis Ergon Chair 2018, and 3D printed chair using Robotic Hybrid Manufacturing at Institute of Advanced Architecture of Catalonia (IAAC) 2019, have previously demonstrated the feasibility of 3d printing with either MBAM or sandwich structures, this method for printing Compound-Curved Sandwich Structures with Robotic MBAM combines these methods offering the possibility to significantly reduce the weight of spanning or cantilevered surfaces by incorporating the structural logic of open grid-core sandwiches with MBAM toolpath printing. Often built with fiber reinforced plastics (FRP), sandwich structures are a common solution for thin wall construction of compound curved surfaces that require a high strength-to-weight ratio with applications including aerospace, wind energy, marine, automotive, transportation infrastructure, architecture, furniture, and sports equipment manufacturing. Typical practices for producing sandwich structures are labor intensive, involving a multi-stage process including (1) the design and fabrication of a mould, (2) the application of a surface substrate such as FRP, (3) the manual application of a light-weight grid-core material, and (4) application of a second surface substrate to complete the sandwich. There are several shortcomings to this moulded manufacturing method that affect both the formal outcome and the manufacturing process: moulds are often costly and labor intensive to build, formal geometric freedom is limited by the minimum draft angles required for successful removal from the mould, and customization and refinement of product lines can be limited by the need for moulds. While the most common material for this construction method is FRP, our proof-of-concept experiments relied on low-cost thermoplastic using a specially configured pellet extruder. While the method proved feasible for small representative examples there remain significant challenges to the successful deployment of this manufacturing method at larger scales that can only be addressed with additional research. The digital workflow includes the following steps: (1) Create a 3D digital model of the base surface in Rhino, (2) Generate toolpaths for laminar printing in Grasshopper by converting surfaces into lists of oriented points, (3) Generate the structural grid-core using the same process, (4) Orient the robot to align in the direction of the substructure geometric planes, (5) Print the grid core using MBAM toolpaths, (6) Repeat step 1 and 2 for printing the outer surface with appropriate adjustments to the extruder orientation. During the design and printing process, we encountered several challenges including selecting geometry suitable for testing, extruder orientation, calibration of the hot end and extrusion/movement speeds, and deviation between the computer model and the physical object on the build platen. Physical models varied from their digital counterparts by several millimeters due to material deformation in the extrusion and cooling process. Real-time deviation verification studies will likely improve the workflow in future studies.

summary This paper is part of a body of research developing an exploratory dialogue between the built form and the environment, via experimentation with performative geometry and material. Here, geometry is considered a design material with the specific capacity to contribute to the performative aspects and kinetic capabilities of building skins.This work opens with a review of emerging opportunities for architects to design materials. It then discusses the concept of Material Active Geometry (MAG) as a means of designing new properties for existing materials. This is followed by a discussion of MAG principles that inform the concepts of flexibility and rigidity in a 3D-printed textile called Flexible Textile Structure (FTS). This research characterizes two FTS types and discusses their potential to be employed in building skins; it also considers combinatory approaches to computational models and physical prototyping. The work concludes with a discussion of the advantages of using FTS, and provides a trajectory for future research in the field of responsive materials and systems.

title What Bricks Want: Machine Learning and Iterative Ruin
doi https://doi.org/10.52842/conf.acadia.2016.072
source ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 72-77
summary Ruin has a bad name. Despite the obvious complications, failure provides a rich opportunity—how better to understand a building’s physicality than to watch it collapse? This paper offers a novel method to exploit failure through physical simulation and iterative machine learning. Using technology traditionally relegated to special effects, we can now understand collapse on a granular level: since modern-day physics engines track object-object collisions, they enable a close reading of the spatial preferences that underpin ruin. In the case of bricks, that preference is relatively simple—to fall. By idealizing bricks as rigid bodies, one can understand the effects of gravitational force on each individual brick in a masonry structure. These structures are sometimes able to ‘settle,’ resulting in a stable equilibrium state; in many cases, it means that they will simply collapse. Analyzing ruin in this way is informative, to be sure, but it proves most useful when applied in series. The evolutionary solver described in this paper closely monitors the performance of constituent bricks and ensures that the most successful structures are emulated by later generations. The tool consists of two parts: a user interface for design and the solver itself. Once the architect produces a potential design, the solver performs an evolutionary optimization; after a few hundred iterations, the end result is a structurally sound version of the unstable original. It is hoped that this hybrid of top-down and bottom-up design strategies offers an architecture that is ultimately strengthened by its contingencies.

summary The rapid emergence of computational design tools, advanced material systems and robotic fabrication within the disciplines of architecture and construction has granted designers immense freedom in form and assembly, while retaining pronounced control over output quality throughout the entirety of the design and fabrication process. Simultaneously, the complexity inherent within these tools and processes can lead to a loss of craft though the production of methodologies, forms and artifacts left with extremely recognizable residues from tooling processes utilized during their production. This paper investigates the fecund intersection of digital technologies and handcraft through core-less carbon fiber reinforced polymer (CFRP) winding as a means of creating a new typology of digital craft blurring the line between human and machine. Through the lens of an innovative wound CFRP shelter rolyPOLY completed during the winter of 2015, this paper will show the exigencies and affordances between the realms of digital and analog methodologies of CFRP winding on large-scale structures.

title From Bones to Bricks: Design the 3D Printed Durotaxis Chair and La Burbuja Lamp
doi https://doi.org/10.52842/conf.acadia.2016.318
source ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 318-325
summary Drawing inspiration from the variable density structures of bones and the self-supported cantilvers of corbelled brick arches, the Durotaxis Chair and the La Burbuja lamp explore a material-based design process by responding to the challenge of designing a 3D print, rather than 3D printing a design. As such, the fabrication method and materiality of 3D printing define the generative design constraints that inform the geometry of each. Both projects are seen as experiments in the design of 3D printed three-dimensional space packing structures that have been designed specifically for the machines by which they are manufactured. The geometry of each project has been carefully calibrated to capitalize on a selection of specific design opportunities enabled by the capabilities and constraints of additive manufacturing. The Durotaxis Chair is a half-scale prototype of a fully 3D printed multi-material rocking chair that is defined by a densely packed, variable density three-dimensional wire mesh that gradates in size, scale, density, color, and rigidity. Inspired by the variable density structure of bones, the design utilizes principal stress analysis, asymptotic stability, and ergonomics to drive the logics of the various gradient conditions. The La Burbuja Lamp is a full scale prototype for a zero-waste fully 3D printed pendant lamp. The geometric articulation of the project is defined by a cellular 3D space packing structure that is constrained to the angles of repose and back-spans required to produce un-supported 3D printing.

title Growth Based Fabrication Techniques for Bacterial Cellulose: Three-Dimensional Grown Membranes and Scaffolding Design for Biological Polymers
doi https://doi.org/10.52842/conf.acadia.2016.488
source ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 488-495
summary Self-assembling manufacturing for natural polymers is still in its infancy, despite the urgent need for alternatives to fuel-based products. Non-fuel based products, specifically bio-polymers, possess exceptional mechanical properties and biodegradability. Bacterial cellulose has proven to be a remarkably versatile bio-polymer, gaining attention in a wide variety of applied scientific applications such as electronics, biomedical devices, and tissue-engineering. In order to introduce bacterial cellulose as a building material, it is important to develop bio-fabrication methodologies linked to material-informed computational modeling and material science. This paper emphasizes the development of three-dimensionally grown bacterial cellulose (BC) membranes for large-scale applications, and introduces new manufacturing technologies that combine the fields of bio-materials science, digital fabrication, and material-informed computational modeling. This paper demonstrates a novel method for bacterial cellulose bio-synthesis as well as in-situ self-assembly fabrication and scaffolding techniques that are able to control three-dimensional shapes and material behavior of BC. Furthermore, it clarifies the factors affecting the bio-synthetic pathway of bacterial cellulose—such as bacteria, environmental conditions, nutrients, and growth medium—by altering the mechanical properties, tensile strength, and thickness of bacterial cellulose. The transformation of the bio-synthesis of bacterial cellulose into BC-based bio-composite leads to the creation of new materials with additional functionality and properties. Potential applications range from small architectural components to large structures, thus linking formation and materialization, and achieving a material with specified ranges and gradient conditions, such as hydrophobic or hydrophilic capacity, graded mechanical properties over time, material responsiveness, and biodegradability.

title The Tectonic of the Hybrid Real: Data Manipulation, Oxymoron Materiality, and Human-Machine Creative Collaboration

summary This paper describes the latest progress of the design platform Digital Impressionism (DI), created by staff and students in the Information Experience Design programme at the Royal College of Art in London. DI aims to bridge human creative thinking with machine computation, under the theoretical method/concept of oxymoron tectonic. Oxymoron tectonic describes the process under which hybrid materiality, that is the materiality created between the digital and the physical, takes form in human-machine creative interactions. The methodology intends to employ multimaterial 3D printers in combination with data manipulation (a process that gives data physical substance), pointclouds, and the influence of intangible environmental data (like sound and wind) to model physical forms by interfacing digital and physical making. In DI, modeling is a hybrid set of actions that take place at the boundary of the physical and digital. Through this interactive platform, design is experienced as a complex, hybrid process, which we call a digital tectonic; forms are constructed via a creative feedback loop of human engagement with nonhuman agents to form a creative network of sustainable and interactive design and fabrication. By developing a mutual understanding of design, machines and humans work together in the process of design and making.

This helped designers in different ways, ranging from modeling complex forms to simulating material behavior. Through presenting two experimental projects, this paper discusses how mathematical form-finding and math-driven form generation techniques could help to achieve not only complex designs, but also products which are optimized in their material use. This is a study to use mathematical functions in favor of mass reduction, as a sustainable design approach.

summary This research investigates the adequacy of the contemporary professional formation to professional practice in the construction market. The work investigates the teaching of building and structures design in schools of architecture and civil engineering in Belo Horizonte. There is evidence that the use of contemporary information technology such as BIM (Building Information Modeling) enables integrated teaching of architecture and engineering, allowing simultaneous work. The hypothesis is that there is a mismatch between contemporary teaching and practice and methodological changes seeking simultaneous practice, respond adequately to contemporary assumptions of learning. The confirmation of this hypothesis subsidizes developments for future research.

summary A building façade plays an important role of reducing artificial lighting by introducing natural light into the interior space. A majority of research and current technology heavily focuses on the optimization of window properties such as the size, location, and glazing with the consideration of external shading device as well as the building wall in order to obtain appropriate natural lit space. In the present work, we propose a 3-dimensional approach that can explore the trade-offs between two objectives, daylight performance and electricity generation, by means of paramedic modeling and multi-objective optimization algorithm. The case study was simulated under the environmental setting of the geographical location of Incheon, Korea without any urban context. Using the proposed methods, 50 pareto-front optimal solutions were derived and investigated based on the achieved daylighting and generated electricity.

summary This paper investigates the potential of a digital geometry system to integrate structural performance-based design and robotic fabrication in the scenario of building a large-scale non-uniform timber shell. It argues that a synthesis of multi-objective optimization, design and construction phases is required in the realization of timber shell construction in architecture practice in order to fulfill the demands of building regulation. Confronting the structural challenge of the non-uniform shell, a digital geometry system correlates all the three phases by translating geometrical information between them. First, a series of structural simulations and experimentations with different objectives are executed to inform the particular shape and tectonic details of each shell component based on its local condition in the geometrical system. Then, controlled by the geometrical system, a hybrid process of different digital fabrication technologies, including a customized robotic timber mill, is established to enable the manufacture of the heterogeneous shell components. Ultimately, the Timber Structure Enterprise Pavilion as the demonstration and evaluation of this method is fabricated and assembled on site through a notational system to indicate the applicability of this research in practical scenarios.

While the fibre constituent in Fibre-Reinforced Polymer (FRP) is mostly used under the form of fabrics, its standard fabrication processes do not rely on its inherent textile attributes. Embedding the fabric qualities in the fabrication of architectural FRP can potentially introduce concepts and properties of biological materials into engineered fibre composites; it can promote and enable the generation of an architectural complexity of a biological nature. The paper presents Fabric Materiality as a framework for a new design and fabrication process and demonstrates through a case study its integration in the fabrication of architectural FRP elements to achieve a complex structure with bio-inspired properties.

summary The project was developed as part of an MArch Architecture design studio that looked at emerging bio-degradable living materials in the form of mycelium bio-composites as a way of manufacturing temporary structures. The project introduced students to laboratory methods for material development and bio-material cultivation. Students were asked to consider the implications of designing with a material that has agency and needs. The studio explored what it means to “make kin” (Haraway 2016) on a planet that has reached a tipping point. It approached the topic from the assumption that the breakdown of existing economic models and resource scarcity offers potent ground for new forms of space making to emerge. The studio looked to nature’s ability to respond to environmental stimuli and design constraints. Students harnessed advances in our scientific understanding to cultivate an architectural language that captures the transient and unstable nature of this new family of biomaterials

summary The timber industry is expanding, including construction wood product applications such as glue-laminated wood products (R. Sikkema et al., 2023). To boost further utilisation of engineered wood products in architecture, further development and optimisation of related tectonic systems is required. Integration of digital design technologies in this endeavour presents opportunities for a more performative and spatially diverse architecture production, even in construction contexts typified by limited means and/or resources. This paper reports on historic precedent case study research that informs an ongoing larger study focussing on novel algorithmic methods for the design and production of lightweight, large-span, catenary glulam roof structures. Given their structural operation in full tension, catenary-based roof structures substantially reduce material needs when compared with those relying on straight beams (Wong and Crolla, 2019). Yet, the manufacture of their non-standard geometries typically requires costly bespoke hardware setups, having resulted in recent projects trending away from the more spatially engaging geometric experiments of the second half of the 20th century. The study hypothesis that the evolutionary design optimisation of this tectonic system has the potential to re-open and expand its practically available design solution space. This paper covers the review of a range of built projects employing catenary glulam roof system, starting from seminal historic precedents like the Festival Hall for the Swiss National Exhibition EXPO 1964 (A. Lozeron, Swiss, 1964) and the Wilkhahn Pavilions (Frei Otto, Germany, 1987), to contemporary examples, including the Grandview Heights Aquatic Centre (HCMA Architecture + Design, Canada, 2016). It analysis their structural concept, geometric and spatial complexity, fabrication and assembly protocols, applied construction detailing solutions, and more, with as aim to identify methods, tools, techniques, and construction details that can be taken forward in future research aimed at minimising construction complexity. Findings from this precedent study form the basis for the evolutionary-algorithmic design and construction method development that is part of the larger study. By expanding the tectonic system’s practically applicable architecture design solution space and facilitating architects’ access to a low-tech producible, spatially versatile, lightweight, eco-friendly, wooden roof structure typology, this study contributes to environmentally sustainable building.
