title	Methods for the Prediction and Specification of Functionally Graded Multi-Grain Responsive Timber Composites
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. 585-594
doi	https://doi.org/10.52842/conf.ecaade.2020.2.585
summary	The paper presents design-integrated methods for high-resolution specification and prediction of functionally graded wood-based thermal responsive composites, using machine learning. The objective is the development of new circular design workflow, employing robotic fabrication, in order to predict fabrication files linked to material performance and design requirements, focused on application for intrinsic responsive and adaptive architectural surfaces. Through an experimental case study, the paper explores how machine learning can form a predictive design framework where low-resolution data can solve material systems at high resolution. The experimental computational and prototyping studies show that the presented image-based machine learning method can be adopted and adapted across various stages and scales of architectural design and fabrication. This in turn allows for a design-per-requirement approach that optimizes material distribution and promotes material economy.

summary	In recent years, digital fabrication projects have explored how to best present complex spatial patterns. These patterns are generated by a series of function clusters and need to be separated into reasonable working sequences for workers. In the stage between design and fabrication, designers and workers typically spend considerable time communicating with each other and prototyping models in order to understand the complex geometry and joint methods of fabrication works. Through the potential of mixed reality technology, this paper proposes a novel form of co-existing interactive workflow that helps designers understand the morphing status of material composition and assists workers in achieving desired results. We establish this co-existing workflow mechanism as an interface between design and reality that includes a HoloLens display, a parametric algorithm, and gesture control identification. This paper challenges the flexibility between the virtual and reality and the interaction between precise parameters and natural gestures within an automation process.

title	Towards an Interactionist Model of Cognizant Architecture - A sentient maze built with swarm intelligence
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. 201-208
doi	https://doi.org/10.52842/conf.ecaade.2020.2.201
summary	Cognizant Architecture is a term used to define sentient and smart structures broadly. In this paper, an 'Interactionist' model of cognizant architecture is proposed as a method of investigating the development process by inverting the conventional concept of maze design. The proposed 'Cognizant Maze' aims to achieve user-architecture micro-interactions through delighting the users, presenting a physical activity equally attractive to kids and adults alike, and activating mind-enticing visual effects. Like many previous innovations, nature is what inspires us in the maze-making process. In modelling the cognizant maze, we develop the concept and workflow of prototyping a form of swarm intelligence. We are particularly interested in exploring how simulated behaviours of swarm intelligence can be manifested in a maze environment for micro-interactions to take place. Combining parametric modelling and Arduino-based physical computing, our current interactive prototyping shows how the maze and its users can 'think, act and play' with each other, hence achieving an interactionist model of cognizant architecture. We reflect that the lessons learned from the Cognizant Maze experiment may lead to further development of cognizant architecture as a propagation of swarm intelligence through multi-layered micro-interactions.

title	Circular Concrete Construction Through Additive FDM Formwork
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 1, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 233-242
doi	https://doi.org/10.52842/conf.caadria.2020.1.233
summary	One of the major downsides of concrete construction is the difficulty to be adapted, modified and deconstructed. In this work, we look at the potential enabled by the use of Additive Formwork based on Fused Deposition Modelling, in order to design and manufacture structural elements which can be assembled and disassembled easily. We call this new typology of structures Circular Concrete Construction. The paper illustrates an integrated computational workflow, which encompasses design and fabrication. Technological aspects of the 3D printed formwork and its application in reversible node and strut connections are described, with reference to the material and structural aspects, as well as prototyping experiments. The work is a proof of concept that opens perspectives for a new type of reversible concrete construction.

title	Embodied Learning through Fabrication Aware Design
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. 145-154
doi	https://doi.org/10.52842/conf.ecaade.2020.2.145
summary	The contemporary culture of geometry-driven design stands as consequence of an institutionalised segregation between the fields of architecture, structure and construction. In turn, digital design methods that are both material and fabrication aware from the outset create space for uncertainty and the potential for embodied learning. Following this principle, this paper summarises the outcomes of a workshop developed to investigate the contribution of fabrication aware design methods in the production of a masonry block using both analogue and digital manufacturing. Students were to develop and investigate a design, through assembly techniques and configurations orientated around manual hot wire cutting, robotic tooling and three-dimensional printing. Outcomes were manufactured and compared regarding work precision, production time, material efficiency, cost and scalability. The analysis indicated that the most accurate results yielded from the robotic tooling system, and simultaneously exhibited the most efficient use of time, while the three-dimensional printer generated the least material waste, due to the nature of additive production. Fabrication aware design and comparative analysis enabled students to make more informed decisions while the use of rapid prototyping facilitated a relationship between digitalization and materiality allowing for a space in which uncertainty and reflection could be fostered. Reinforcing that fabrication aware design methods can unify the field and provide guidance to designers over multi-lateral aspects of a project.

title	FORM{less}
source	ACADIA 2020: Distributed Proximities / Volume I: Technical Papers [Proceedings of the 40th Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-95213-0]. Online and Global. 24-30 October 2020. edited by B. Slocum, V. Ago, S. Doyle, A. Marcus, M. Yablonina, and M. del Campo. 526-535

summary	Form{less} focuses on the creation of complex thin-shell concrete forms using robotically thermoformed plastic molds. Typically, similar molds would be created using the vacuum forming process, producing direct replications of the pattern. Creating molds with this process is not only time- and material-intensive but also costly if customization is involved. Thin-shell concrete forms often require a labor-intensive process of manually finishing the open-face surface. The devised process of thermoforming two nested molds allows the concrete to be cast in between, with finished surfaces on both sides. Molds made with polyethylene terephthalate glycol (PETG) allow the formwork to be reused and recycled. The research and fabrication work include the development of heating elements and the creation of the robotic process for forming the PETG. The PETG is manipulated via a robotic arm, with a custom magnetic end effector. The integration of robotics not only enables precision for manufacturing but also allows for replicability with unrestricted threedimensional deformation. The repeatable process allows for rapid prototyping and geometric customization. Design options are then simulated computationally using SuperMatterTools, enabling further design exploration of this process without the need for extensive physical prototyping. This research aims to develop a process that allows for the creation of complex geometries while reducing the amount of material waste used for concrete casting. The novelty of the process created by dynamically forming PETG allows for quick production of formwork that is both customizable and replicable. This method of creating double-sided building components is simulated at various scales of implementation.

title	Developing a Digital Interactive Fabrication Process in Co-existing Environment
source	Proceedings of the 2020 DigitalFUTURES The 2nd International Conference on Computational Design and Robotic Fabrication (CDRF 2020)
doi	https://doi.org/https://doi.org/10.1007/978-981-33-4400-6_3
summary	In the stage of prototype practice, the maker mainly works by himself, but it needs to test and adapt to find correct fabrication method when maker didn’t have clearly fabrication description. Therefore, rapid prototyping is very important in the prototype practice of the maker. “Design- Fabrication-Assembly” (DFA)- an integration prototyping process which helps designers in creating kinetic skin by following a holistic process. However, DFA lacks a medium for communication between design, fabrication and assembly status. This paper proposes a solution called co-existing Fabrication System (CoFabs) by combining multiple sensory components and visualization feedbacks. We combine mixed reality (MR) and the concept of digital twin (DT)–a device that uses a virtual interface to control a physical mechanism for fabrication and assembly. By integrating virtual and physical, CoFab allows designers using different methods of observation to prototype more rigorously and interactively correct design decisions in real-time.

summary	Driven by the ecological crisis looming over the 21st century, the construction sector must urgently seek alternative design solutions to current building practices. In the wake of emergent digital technologies and novel material strategies, this research proposes a lightweight architectural solution using natural fiber-reinforced polymers (NFRP), which elicit interest for their inherent renewability as compared to high-performance yarns. Two associated fabrication techniques are deployed: tailored fiber placement (TFP) and coreless filament winding (CFW), both favored for their additive efficiencies granted by strategic material placement. A hypothesis is formed, postulating that their combination can leverage the standalone complexities of molds and frames by integrating them as active structural elements. Consequently, the TFP enables the creation of a 2D stiffness-controlled preform to be bent into a permanent scaffold for winding rigid 3D fiber bodies via CFW. A proof of concept is generated via the small-scale prototyping and testing of a stool, with results yielding a design of 1 kg capable of carrying 100 times its weight. Laying the groundwork for a scaled-up architectural proposal, the prototype instigates alterations to the process, most notably the favoring of a modular global design and lapped preform technique. The research concludes with a discussion on the resulting techno-implications for automation, deployment, material life cycle, and aesthetics, rekindling optimism towards future sustainable practices.

title	Robotic Fabrication with Bioplastic Materials - Digital design and robotic production of biodegradable objects
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. 603-612
doi	https://doi.org/10.52842/conf.ecaade.2020.1.603
summary	Bioplastics are materials that are composed of renewable organic biomass sources and thus they are inherently biodegradable. On top of their ecological advantages to standard plastics they help to conserve fossil raw materials and the dependency on mineral oil. Recent advancements in digital design and robotic materialisation have introduced innovative methods for the realisation of complex geometries and direct experimentation through physical prototyping. Within this collaborative course between the Dessau Department of Design and the Dessau Institute of Architecture, we set out to explore the potentials of self-made bioplastic materials in combination with cutting-edge robotic fabrication in order to produce compostable products. Throughout the course the participants got acquainted with the fundamentals of parametric design to robotic production while performing systematic scientific experiments with bioplastics to develop the perfect material for robotic production. The paper presents a number of recipes on how to create bioplastics in a DIY manner. Moreover, the material research methodology, as well as robotic fabrication strategies behind each of the projects, are discussed in detail.

title	Hygro-Compliant: Responsive Architecture with Passively Actuated Compliant Mechanisms
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 1, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 223-232
doi	https://doi.org/10.52842/conf.caadria.2020.1.223
summary	Research investigating water-driven passive actuation demonstrates the potential to transform how buildings interact with their environment while avoiding the complications of conventionally powered actuation. Previous experiments evidence the possibilities of bi-layer materials (Reichert, Menges, and Correa 2015; Correa et al. 2015) and mechanical assemblies with discretely connected actuating members (Gupta et al. 2019). By leveraging changes in weather to power actuated building components these projects explore the use of smart biomaterials and responsive building systems. Though promising the implementation of these technologies requires deep engagement into material synthesis and fabrication. This paper presents the design and prototyping of a rain responsive faÃ§ade system using chitosan hygroscopic films as actuators counterbalanced by programmed compliant mechanisms. Building on previous work into chitosan film assemblies this research focuses on the development of compliant mechanisms as a means of controlling movement without over-complicated rotating parts.

title	Transient Materialization â€“ Robotic Metal Curving
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 2, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 423-432
doi	https://doi.org/10.52842/conf.caadria.2020.2.423
summary	This paper introduces the notion of transient materialization to investigate a novel approach of robotic fabrication. Transient materialization explores a new logic of materialization that takes the advantage of differentiated material states to generate form at a particular moment through computation and fabrication technologies. Specifically, this design research explains a unique design and fabrication process, opening up a new method of materializing architectural form that emerges from the interweaving of data, the material capacity (plastic deformation), timing, and machine capacity. Hence, to examine this research direction, this paper conducts an experimental project, Robotic Metal Curving, through hands-on material experiments, as well as the development of algorithms, robot motion, and prototyping machines. This experiment utilizes an induction heating technique in cooperation with a six-axis industrial robotic arm and fabrication equipment used to shape each metal rod into a three-dimensional curve at a transient moment. In addition, the project focuses not only on developing a robotic metal curving system but also apply this technique in large scale by fabricating a wire-frame structure.

doi	https://doi.org/10.52842/conf.caadria.2020.2.453
summary	This research proposes that mass timber panels can not only enable a new type of architecture that is sustainable, but that also sounds better. As mass timber construction often exposes the wood structure, and these panels are carefully constructed in factory settings, these panels have the potential to be built so that the acoustically absorptive, reflective, or sound scattering acoustic properties of surfaces can be integrated into the constructive logic and architectural aesthetic of the building. This paper specifically investigates the potentials of the sound scattering performance of cross laminated timber (CLT) panels. Through design, simulation, and prototyping various surface designs are investigated.

doi	https://doi.org/10.52842/conf.caadria.2020.2.473
summary	As digital design and fabrication are becoming increasingly prevalent, it is essential to consider how these technologies can be made more affordable and intuitively introduced to individual designers with limited computing skills. In this paper, we present an affordable personal robotic fabrication platform, PICA, consisting of a 3D printed robotic arm with a set of controller programs. The platform allows designers with limited computational design skills to assemble motors and 3D printed parts easily and to operate it in a code-free environment with direct manipulation through 3D modeling software. With the real-time communication between 3D modeling software and this robotic fabrication platform, PICA also allows designers to efficiently change the topological properties of geometry during the fabrication process. Based on a comparative observation of several application scenarios of using PICA among two groups of architecture students, the research can be summarized as follows: 1.) The project has proved to be an affordable approach to ease the materializing process when converting a designer's initial intent from digital space to a physical prototype. 2.) Designers could be facilitated by utilizing this robotic fabrication platform, especially during the period of conceptual design.

summary	The LightVault project demonstrates a novel robotic construction method for masonry vaults, developed in a joint effort between Princeton University and the global architecture and engineering firm Skidmore, Owings & Merrill (SOM). Using two cooperating robotic arms, a full-scale vault (plan: 3.6 × 6.5 m, height: 2.2 m) made up of 338 glass bricks was built live at the “Anatomy of Structure: The Future of Art + Architecture” exhibition. A major component of the project was developing a fabrication method that could be easily adapted to different robotic setups since the research, prototyping, and final exhibition occurred on different continents. This called for approaches that balanced the generic and the specific, allowing for quick and flexible construction staging and execution. The paper is structured as follows. First, we introduce the notion of transferability in robotic construction and then elaborate on this concept through the four major challenges in the LightVault project development: (1) prototype scalability, (2) end-effector design, (3) path planning and sequencing, and (4) fabrication tolerances. To develop and test solutions for these challenges, we iterated through several prototypes at multiple scales, with different materials for the standardized bricks, and at three distinct locations: Embodied Computation Lab, Princeton, US; Global Robots Ltd., Bedford, UK; and Ambika P3 gallery, London, UK. While this paper is specifically tailored to the construction of masonry structures, our long-term goal is to enable more robotic fabrication projects that consider the topic of transferability as a means to develop more robust and broadly applicable techniques.

summary	Though highly robust and economical, traditional lamella and reciprocal structural systems cannot adapt to surfaces with complex double curvature; as the timber members are standardized with no variation. Recent research has explored the use of computation for design, structural optimization, and use of robotic systems for the automated fabrication of timber joints. The disconnection between fabrication and assembly makes the construction of non-uniform double-curved reciprocal frames challenging, due to the required precise placement of discrete members with compound angle butt joints. This project investigates the use of robotic fabrication to cut and assemble a timber reciprocal frame assembly. A computational model was created to generate the double-curved reciprocal frame geometry. Within this computational framework, joint analysis, fabrication, and assembly were monitored and adjusted to meet limiting factors. An industrial robot was implemented as a bridge between the computational model and the physical construction. This paper presents a number of novel computational and robotic fabrication techniques in designing, cutting, and positioning. These techniques were explored through the robotic fabrication and assembly of a demonstrator - a double-curved reciprocal frame wall.

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	This research brings into question, the ever-increasing role of CAD/CAM technologies in architectural design education. Within this scope, a design workshop for the students of architecture was organized, to investigate the effects of design tools and methods on the design process. Participants were asked to start their design by using traditional methods, followed by developing models with CAD -3d modelling programmes- and prototyping with CAM -3d printers-. Design processes were recorded visually and auditory, during the workshop for protocol analysis. Relationship between design approaches, design tools and design process was analysed in detail by observing the frequency of used concepts, actions and words in both methods. Outcomes of the research showed strengths and weaknesses of design methods for different approaches.

title	Towards machine learning for architectural fabrication in the age of industry 4.0
source	International Journal of Architectural Computing vol. 18 - no. 4, 335–352
summary	Machine Learning (ML) is opening new perspectives for architectural fabrication, as it holds the potential for the profession to shortcut the currently tedious and costly setup of digital integrated design to fabrication workflows and make these more adaptable. To establish and alter these workflows rapidly becomes a main concern with the advent of Industry 4.0 in building industry. In this article we present two projects, which presents how ML can lead to radical changes in generation of fabrication data and linking these directly to design intent. We investigate two different moments of implementation: linking performance to the generation of fabrication data (KnitCone) and integrating the ability to adapt fabrication data in realtime as response to fabrication processes (Neural-Network Steered Robotic Fabrication). Together they examine how models can employ design information as training data and be trained to by step processes within the digital chain. We detail the advantages and limitations of each experiment, we reflect on core questions and perspectives of ML for architectural fabrication: the nature of data to be used, the capacity of these algorithms to encode complexity and generalize results, their task-specificness versus their adaptability and the tradeoffs of using them with respect to conventional explicit analytical modelling.
