title	Robotic 3D Printing Multilayer Building Envelope

summary	This research explores the use of robotic pellet extrusion 3D printing (3DP) in the production of a multifunctional thermoplastic building envelope. A computational design method was developed to generate multi-layered systems of interconnected volumes using minimal surfaces, combined with a rib-stiffening approach that accommodates fabrication constraints. The investigation highlights the development of an integrated system that includes robotic end-effector tooling, programming/control methods to allow “endless” prints, as well as specific toolpath strategies to improve print speed and quality. These developments are then demonstrated through the design and fabrication of two 2.2 m by 1.1 m building envelope panels, and the results are discussed along with specific details of the printing process. The innovations of this research are: (1) a computational design tool that allows intuitive generation and adaptation of multilayer building envelopes to site criteria; and (2) a robust robotic control system allowing continuous, uninterrupted printing at architectural scale with minimal supervision and high-quality surface finish.

title	Ceramic Incremental Forming–A Rapid Mold-Less Forming Method of Variable Surfaces
doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_43
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
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.

summary	This project explores the advantages of employing continuum material topology optimization in a 3D non-standard lattice structure through fiber additive manufacturing processes (Figure 1). Additive manufacturing (AM) has gained rapid adoption in architecture, engineering, and construction (AEC). However, existing optimization techniques often overlook the mechanical anisotropy of AM processes, resulting in suboptimal structural properties, with a focus on layer-by-layer or planar processes. Materials, processes, and techniques considering anisotropy behavior (Kwon et al. 2018) could enhance structural performance (Xie 2022). Research on 3D printing materials with high anisotropy is limited (Eichenhofer et al. 2017), but it holds potential benefits (Liu et al. 2018). Spatial lattices, such as space frames, maximize structural efficiency by enhancing flexural rigidity and load-bearing capacity using minimal material (Woods et al. 2016). From a structural design perspective, specific non-standard lattice geometries offer great potential for reducing material usage, leading to lightweight load-bearing structures (Shelton 2017). The flexibility and freedom of shape inherent to AM offers the possibility to create aggregated continuous truss-like elements with custom topologies.

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	Algebraic analysis and reconstruction of the Philips Pavilion’s hyperbolic paraboloid surfaces
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 1, pp. 61–75
summary	In this article, we present a procedure to derive algebraic descriptions from geometric descriptions of trimmed hyperbolic paraboloid (or ‘hypar’) surfaces. We contextualise this procedure historically, and we illustrate its application using the 1958 Philips Pavilion by Le Corbusier and Iannis Xenakis as a case study. The procedure uses parametric modelling and computational optimisation to converge on close algebraic ap- proximations of hyperbolic paraboloid geometry through a successive breakdown of vast search spaces. It departs from coordinate data of three or four vertices of a geometrically described hyperbolic paraboloid and yields the surface’s two quadratic coefficients, the coordinates of its centroid location and the rotation angles of its spatial orientation. The procedure exemplifies the under-explored analytical (as opposed to generative) use of computational optimisation and parametric modelling in the field of architectural computing.

summary	Shingle covering of multi-curved surfaces is usually a manual process with no precise plan for the arrangement and assembly of shingle elements. Such processes lack the computational capacity of algorithmic methods for modeling, analysis, and optimization of shingle systems within a seamless digital workflow. As a solution, this paper presents an algorithmic procedure for the design and assembly of shingle covering systems for multi-curved surface structures. The proposed algorithm evaluates the reference surface curvatures to generate an efficient layout of shingles of identical size. The proposed model generates the arrangement of shingles based on given input parameters including the shingle dimensions and overlapping domains. For a precise and quick on-site assembly the corresponding nailing strips are also automatically generated on which the shingles could be installed. The applications and limitations of the proposed algorithm are discussed through a detailed analysis of various case studies.

title	An Assessment of Tool Interoperability and its Effect on Technological Uptake for Urban Microclimate Prediction with Deep Learning Models
doi	https://doi.org/10.52842/conf.caadria.2022.1.273
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. 273-282
summary	The benefits of deep learning (DL) models often overshadow the high costs associated with training them. Especially when the intention of the resultant model is a more climate resilient built environment, overlooking these costs are borderline hypocritical. However, the DL models that model natural phenomena‚conventionally simulated through predictable mathematical modelling‚don't succumb to the costly pitfalls of retraining when a model's predictions diverge from reality over time. Thus, the focus of this research will be on the application of DL models in urban microclimate simulations based on computational fluid dynamics. When applied, predicting wind factors through DL, rather than arduously simulating, can offer orders of magnitude of improved computational speed and costs. However, despite the plethora of research conducted on the training of such models, there is comparatively little work done on deploying them. This research posits: to truly use DL for climate resilience, it is not enough to simply train models, but also to deploy them in an environment conducive of rapid uptake with minimal barrier to entry. Thus, this research develops a Grasshopper plugin that offers planners and architects the benefits gained from DL. The outcomes of this research will be a tangible tool that practitioners can immediately use, toward making effectual change.

title	Felt and Fold - Design and manufacturing of customized nonwovens through robotic needle felting
doi	https://doi.org/10.52842/conf.ecaade.2022.1.195
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. 195–204
summary	This paper explores the potential of robotic needle felting for customized production of nonwoven textiles and their architectural applications. The possibility to program the robotic movement and locally control fiber density and distribution allows the design of nonwoven, heterogeneous materials with graded properties not by differentiating their chemical composition, but rather controlling their mechanical structure. We propose a parametric design and fabrication workflow relying on a 6-axis robotic arm. We describe design techniques for the generation of felted surfaces with varying material properties and their translation to instructions for robotic felting, as well as the physical fabrication setup. Within our research, the ability to locally differentiate material properties is further explored to create three-dimensional folding behaviors. We study how fiber densities affect their folding ability and geometry, examine qualities of resulting edges, analyze how they affect folding and finally design targeted folded structures by informing the felting pattern. While robotic felting has not yet found significant applications in architecture, the designs and prototypes demonstrate its potential in the architectural context, as it suggests new solutions for recyclable, circular building components or surfaces.

title	Chromogenic Composites - A case study combining thermochromics with heat transfer simulations and digital fabrication in architectural education
doi	https://doi.org/10.52842/conf.ecaade.2022.1.291

summary	Over the last few decades, environmental considerations have become increasingly important in architecture. To predict and simulate material changes and environmental forces can help architects to articulate surfaces. In architectural education, an increasing amount of the curricula are engaging with aspects of energy design, sustainability, and environmental simulations. The successful integration of related novel technologies in education has been demonstrated in the past. This paper documents a technical seminar that focused on the combination of digital environmental simulations and smart materials to create chromogenic prototypes for environmentally responsive architectural composites. Thermochromic chromogenics are substances that reversibly change colour depending on temperature. Specifically, the task was to come up with novel techniques to combine such materials with varying substrates to achieve dynamic panels. The course design was informed by a variety of design research and learning concepts. Students were asked to use digital heat transfer simulations to predict the smart material changes of computationally designed panels. Each of the eight idiosyncratic prototypes was modified with a variety of techniques and coated with thermochromic ink to achieve complex heat signature patterns. The resulting chromogenic composites were documented and analyzed using photos and infrared thermography. The seminar’s results showed that the three aspects (simulation, material, fabrication) can help to introduce eco-relevant technologies to design education. For this paper, both the outcomes and the course design itself were reviewed to better understand the co-creation process of the three aspects. This evaluation provided a rich repertoire of possibilities to combine different technologies for creative environmental design in architecture; all while maintaining an engaging teaching environment.

summary	The surge in mass timber buildings being constructed introduces unique acoustical challenges as mass timber is more permissible for sound to travel across floors, ceilings, and walls, especially for lower frequencies. In order to address these acoustical challenges, the absorption qualities of Helmholtz resonators and surface diffusion of scattering surfaces are leveraged by combining the two systems in an integrated structure using the tectonics of mass timber construction. This paper investigates the potential of Helmholtz resonators to be used in combination with sound scattering surfaces to achieve optimal performance in cross laminated timber (CLT) panels through the use of a hexagonal pattern as the underlying design strategy.

summary	This paper introduces and investigates NiChrome wire sintering, a novel fabrication technique in the field of additive manufacturing. With a combination of differentiated material states and material properties, this research generates forms with different sintering strategies through computation and fabrication systems. Rather than creating objects through selectively depositing melted material in a predetermined path, layer-by-layer, this rapid prototyping methodology generates 2D or 3D spatial wireframes by weaving NiChrome wire and sintering thermoplastic polyurethane (TPU) onto it by utilizing the instantaneous high temperature of NiChrome wire after electrification. A series of experiments is presented utilizing a proportional integral derivative (PID) temperature control system in cooperation with thermal camera equipment to ensure consistent results under the same conditions. In addition, the project focuses not only on developing NiChrome wire sintering systems but also on the applicabilities of this technique by fabricating wireframe surfaces under different situations.

title	3D Printing with Bacterial Cellulose-Based Bioactive Composites for Design Applications
doi	https://doi.org/10.52842/conf.ecaade.2022.1.077
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. 77–84
summary	The bacterial cellulose (BC) biofilms are explored in design applications as replacements to petroleum-based materials in order to overcome the irreversible effects of the Anthropocene. Unlike biomaterials, designers as mediators could collaborate with bioactive polymers as a form of wetware to manufacture living design products with the aid of novel developments in biology and engineering. Past and ongoing experiments in the literature show that BC has a strong nanofibril structure that provides adhesion for attachment to plant cellulose-based networks and it could grow on the surfaces of the desired geometry thanks to its inherited, yet, controllable bio-intelligence. This research explores BC-based bioactive composites as wetware within the context of digital fabrication in which the methodology involves distinct, yet integrated, three main stages: Digital design and G-code generation (software stage); BC cultivation and printable bioactive composite formulation (wetware stage); digital fabrication with a customized 3D printer (hardware stage). The results have shown that the interaction of BC and plant- based cellulose fibers of jute yarns has enhanced the structural load-bearing capacity of the form against compressive forces, while pure BC is known only by its tensile strength. Since the outcomes were fabricated with the use of a bioactive material, the degradation process also adds a fourth dimension: Time, by which the research findings could further establish a bio-upcycling process of wastes towards biosynthesis of valuable products. Moreover, developing a BC-based bioactive filament indicates potentially a feasible next step in the evolution of multiscale perspectives on the growth of habitable living structures that could reinforce the interaction between nature and architecture through collaboration with software, hardware, and wetware in innovative and sustainable ways.

summary	Robotic additive manufacturing has garnered significant research and development interest due to its transformative potential in architecture, engineering, and construction as a cost-effective, material-efficient, and energy-saving fabrication method. However, despite its potential, conventional approaches heavily depend on meticulously optimized work environments, as robotic arms possess limited information regarding their immediate surroundings (Bechthold, 2010; Bechthold & King, 2013). Furthermore, such approaches are often restricted to planar build surfaces and slicing algorithms due to computational and physical practicality, which consequently limits the feasibility of robotic solutions in scenarios involving complex geometries and materials. Building on previous work (Çapunaman et al., 2022), this research investigates conformal 3D printing of clay using a 6 degrees-of-freedom robot arm and a vision-based sensing framework on parametrically reconfigurable tensile hyperbolic paraboloid (hypar) formwork. In this paper, we present the implementation details of the formwork system, share findings from preliminary testing of the proposed workflow, and demonstrate application feasibility through a design exercise that aims to fabricate unique components for a poly-hypar surface structure. The formwork system also offers parametric control over generating complex, non-planar tensile surfaces to be printed on. Within the scope of this workflow, the vision-based sensing framework is employed to generate a digital twin informing iterative tuning of the formwork geometry and conformal toolpath planning on scanned geometries. Additionally, we utilized the augmented fabrication framework to observe and analyze deformations in the printed clay body that occurs during air drying. The proposed workflow, in conjunction with the vision-based sensing framework and the reconfigurable formwork, aims to minimize time and material waste in custom formwork fabrication and printing support materials for complex geometric panels and shell structures.

summary	The current pandemic and the climate crisis urge people to rethink their relationships to the natural and urban environments. In this research we turned to nature for inspiration to find new ways to keep human environments clean and healthy. This paper presents a computational and experimental methodology to design self-cleaning architectural surfaces from chitin biomaterial modeled after butterfly wings. We fabricate surface architectures using parametric modeling, 3d printing, and molding of chitin biomaterial, and assess their performance using mechanical testing, experimental and computational simulations. The goal is to provide an alternative to hydrophobic fossil fuel-based plastics using surface morphologies of biomaterials to achieve structural rigidity and self- cleaning properties in architectural surfaces.

title	Rendering Sketches - Interactive rendering generation from sketches using conditional generative adversarial neural network

summary	Architects use sketches in the early design phase to organize and elaborate their initial ideas, and those initial sketches often support ideation for the final design. However, the sketches in the early design phase tend to be abstract and hard to interpret. Minimal prior works provide tools for quick visualization of the initial sketch. This study provides a scheme for architects and designers to generate preliminary renderings in the early design stage. In this study, we use conditional generative adversarial networks (cGAN) as the frame and introduces an updater network to the existing cGAN to support the iterative design process. A sketch serves as input to see the rendering and update the sketch based on the generated renderings by adding more resolution and details. The network is able to generate a reasonable rendering from the single-image network, and is able to update the renderings iteratively via the updater network. The dataset is collected from residential buildings exclusively, but the architectural categories can be expanded to other types of buildings in the future. Results show that the proposed scheme is able to provide reasonable renderings from sketches, and the generated rendering can be updated with a higher level of details within a second if the user provides a more detailed sketch. The contribution of this study includes introducing an updater network to the existing algorithm to enable iterative input and provides an alternative enhancement approach to the resolution of the generated image.

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.

title	Modeling irregular and complex forms
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	Computational technologies provide arguably the first real opportunity architectural design has had for a comprehensive description of built form. With the advent of affordable computer-aided design systems (including drafting, modeling, visualization and simulation tools), architects believe they can be in full control of geometric aspects and, through these, of a wide spectrum of other aspects that are implicit or explicit in the geometric representation. This belief is based primarily on the efficiency and effectiveness of computer systems, ranging from the richness and adaptability of geometric primitives to the utility of geometric representations in simulations of climatic aspects. Such capabilities support attempts to design and construct more irregular or otherwise complex forms. These fall under two main categories: (1) parsing of irregularity into elementary components, and (2) correlation of the form of a building with complex geometric structures.The first category takes advantage of the compactness and flexibility of computational representations in order to analyse the form of a design into basic elements, usually elementary geometric primitives. These are either arranged into simple, unconstrained configurations or related to each other by relationships that define e.g. parametric relative positioning or Boolean combinations. In both cases the result is a reduction of local complexity and an increase of implicit or explicit relationships, including the possibility of hierarchical structures.The second category attempts to correlate built form with constraints that derive usually from construction but can also be morphological. The correlation determines the applicability of complex geometric structures (minimally ruled surfaces) to the description of a design. The product of this application is generally variable in quality, depending upon the designer's grounding in geometry and his ability to integrate constraints from different aspects in the definition of the design's geometry.Both categories represent a potential leap forward but are also equally hampered by the rigidity of the implementation mechanisms upon which they rely heavily. The paper proposes an approach to making these mechanisms subordinate to the cognitive and technical aspects of architectural thinking through fuzzy modeling. This way of modeling involves a combination of (a) canonical forms, (b) tolerances around canonical forms and positions, (c) minimal and maximal values, (d) fuzzy boundaries, and (e) plastic interaction between elements based on the dual principles of local intelligence and autonomy. Fuzzy models come therefore closer to the intuitive manners of sketching, while facilitating transition to precise and complex forms. The paper presents two applications of fuzzy modeling. The first concerns the generation of schematic building layouts, including adaptive control of programmatic requirements. The second is a system for designing stairs that can adapt themselves to changes in their immediate environment through a fuzzy definition of geometric and topological parametrization.

summary	The microscopic universe represents a realm of intriguing possibilities, albeit one that remains largely unexplored. Promoting science through innovative approaches is vital, and the emergence of STEAM stands as a viable tool for that. Architecture, as a realm that directly impacts society, presents a unique potential to convey this new language, manifesting through building facades, walls, or urban furnishings. This study aims to unearth this potential by scrutinizing microscopic images and transposing this universe onto surfaces. The technique involves the 3D mapping of patterns extracted from micrographs and their application onto minimal surfaces. Through digital fabrication, the microcosmic and architectural realms converge within a transdisciplinary framework. This research underscores the feasibility to connect various knowledge domains, rendering them accessible to a broad audience, enabling microscopic imagery to explore, in novel contexts such as architectural ones, a playful and inclusive means of presentation.

title	Zero-Waste, Flat-Packed, Tri-Chord Truss: Continued Investigations of Structural Expression in Parametric Design"

summary	The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models. This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes. This paper will expand (greatly) upon previous research into bi-chord truss designs, developing a tri-chord truss, which is parametrically linked to its structural moment diagram. The cross section of each truss is formed based on the loading condition for each beam. This truss design has been developed through a thorough series of analytical models and tests performed digitally, to scale and in full scale. The tri-chord truss is capable of resisting rotational failures well beyond the capacity of the bi-chord designs previously developed. The results are complex, and elegant expressions of structural logics embodied in a tightly constrained functional design.

summary	With a specific focus on robotic stereotomy, two full-scale vault structures were designed to explore the potential of self-standing building structures made from interlocking components; these structures were fabricated with a track-mounted industrial-scale robot (ABB 4600). To respond to the economic affordances of robotic subtractive cutting, all uniquely shaped structural modules came from one block of material (48"" x96"" x36""). Through the discretization of curvilinear tessellated vault surfaces into a limited number of uniquely shaped modules with embedded form-fitting connectors, the project exhibited the potential for programming a robot to cut ruled surfaces to produce freeform shells of any kind. Representing nearly zero-waste construction, the developed technology can potentially be used for self-supporting emergency shelters and field medical clinics, facilitating easy shipping and speedy assembly. Without using any scaffolding, a few people can erect and dismantle an entire mortar-free structure at the construction site. The disassembled structure occupies minimal space in storage, and the structure’s pieces can be transported to the site in stacks. Robot milling is a common technique for removing material to transform a block into a sculptural shape. Unlike milling techniques that produce significant waste, we used a hotwire that sliced through a Geofoam block to create almost no waste pieces. Since the front side of every module was concurrent with the backside of the next one, such a decision allowed to operate just one cut per front side of each module. In this case, by having three cuts, two neighboring modules were fabricated. The form of the structure and its modules emerged from the constraints of the fabrication technique, aiming to establish a feedback loop between geometry, material, simulation, and tool. By cross-referencing geometric data across Grasshopper, a customized tessellation script was made to breakdown a vault into its modular ruled surface constructs.
