title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
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	Architectural and Engineering Communities are interested in the detection of differences between different representations of the same building. These can be the differences between the design and the as-built-state of a building, or the detection of changes that occur over time and that are documented by consecutive 3D scans. Current approaches for the detection of differences between 3D scans and 3D building models are however laborious and work only on the level of a building element. We demonstrate a novel highly automated workflow to detect differences between representations of the same building. We discuss the underlying tools and methods and the ways to communicate deviations and differences in an appropriate manner and evaluate our approach with a rich set of real world datasets.

summary	Contemporary advanced simulation software allow for a higher accuracy in the understanding of material behaviour. The increase in computational power is enabling designers to get much closer to real time physical simulations, which facilitates the inheritance of those tools in their design workflows.However, the use of those tools is normally limited to a series of specific steps within the entire workflow, rather than a feature integrated in the design process itself.Softmodelling is an open source Java application which aims to bridge this gap by seamlessly integrating physical simulations in every step of the design process, giving designers the ability to not only test structural behaviours of a given output, but also allow them to design while taking both structural stability and material behaviour into account at every stage.This paper will discuss the design and evolution of the software, as well as showcase physical prototypes which explore the possibilities of such design methods. These projects are fundamental in materialising the evolution of Softmodelling, towards becoming an application that does not only enable the design of flexible elements, but also facilitates their manufacturing and assembly into large scale structures.

summary	Finding an attractive or best-fit neighborhood for a new resident of any city is not only important from the perspective of the resident him or herself, but has larger implications for developers and city planners. The environment or mood of the right neighborhood is not simply created through traditional characteristics such as income, crime, or zoning regulations - more ephemeral traits related to user-perception also have significant weight. Using datasets and tools previously unassociated with real-estate decision-making and neighborhood planning, such as social media and machine learning, we create a non-deterministic and customized way of discovering and understanding neighborhoods. Our project creates a customizable ranking system for the 195 neighborhoods in New York City that helps users find the one that best matches their preferences. Our team has developed a composite weighted score with urban spatial data and social media data to rank all NYC neighborhoods based on a series of questions asked to the user. The project's contribution is to provide a scientific and calibrated understanding of the impact that socially oriented activities and preferences have towards the uses of space.

title	A smart bracelet: An alternative interfaces between performer and audience
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 311-319

summary	Performing arts has been one of the main recreational activ- ities in people’s life. However, most performing arts, performers usu- ally used one direction to express performing contents to the audienc- es. It means there is no real-time communication channel between the performers and audience in most performance. Hence the challenge of this research is how to provide a better relationship between the per- formers and audience without disturbing the show? This research we implemented a bio-sensor embedded smart bracelet which is able to transmit the feelings from user’s to stage by monitoring biological signal (ex: Galvanic skin response) immediately. When most audienc- es have the same physiological reaction to a certain level, the stage scene would be changed the colour and pattern to let performers know how the audiences’ feeling now. Performers would enhance self- confidence and then incorporate the audiences’ feedback to create their future performance. By applying this interactive interface to per- forming arts, we explored a new vision of performance that can not only enhance the diversity of performance but also provide a comfort- able communication channel between performers and audiences, and improve the confidence of the performers.

title	Multiflight - Creating Interactive Stairs through Positive Technology
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 295-308
summary	This paper details a pedagogical project which calls for an improved design performance of the existing built environment through the use of smart technology and data-driven design. The project is an investigation into ways in which to improve the performance of a ‘pre-selected university building’ through the use of a media facade that allows for interactive experiences. Existing problems of the selected building have been identified through observation and research using a rich picture and agile approach. An underutilised staircase was selected as the focus site for a series of computational design and interactive design studies. The brief of this mini-research project aims to encourage more people to use the stairs and create a memorable experience with a technological approach through the application of a site specific interactive media installation. The project is an interactive staircase which utilises LED strips and generative sound. The project features a series of light boxes which are connected to the existing staircase balustrade. Arduino, passive infra-red sensors, and other motion detection sensors were used to allow for light and generative sound interaction with users using visual scripting tools and a generative design platform. Sensing technology was used as a real-time data-gathering device during the site analysis phase as well as an input device for the designed prototype to allow the testing of the data-driven design. This paper details the study and resultant interactive prototypes. It also discusses the exploration of performance based design ideas into design workflows and the integration of sensing tools into the design process. It concludes by identifying possible implications on using the Internet of Things concepts to facilitate the design of interactive architecture.

title	Modeling Decorative Forms and Design Knowledge

summary	Form analysis in architecture is a method to increase knowledge of human made objects, by observation and description. Modeling attempts to identify characteristics carried by these objects and the rules of their production. Two approaches are relevant here. The first concerns the analysis and modeling of an object corpus (decors worn by windows), belonging to colonial architecture of Tunis from the late 19th to early 20th century and the second deals from a GIS, storing and mapping the forms variation, taken on the analyzed objects. The set allows developing tools for decision support, used not only in the description of a corpus, but also ultimately to lead to the architectural and stylistic classification of the city buildings.

title	Parametricism for Urban Aesthetics - A flawless order behind chaos or an over-design of complexity
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 105-112
summary	Over the last decade, paradigm shifts in the philosophy of space-time relations, the change from space-time to spatio-temporality, caused significant changes in the design field, and introduced new variations and discourses for parametric approaches in architecture. Among all the discourses, parametricism is likely the most spectacular one. The founder of parametricism, Patrik Schumacher (2009) describes it as “a new style,” which has “the superior capacity to articulate programmatic complexity;” and “aesthetically, it is the elegance of ordered complexity in the sense of seamless fluidity.” In its theoretical background, Schumacher (2011) affiliates this style with the philosophy of autopoiesis, the philosophy that stands between making and becoming. Additionally, parametricism concerns not only the physical geometry in making of form; but also discusses the relational and causal aspects in becoming of form. In other words, it brings the aesthetic qualities in making through the topological intelligence behind becoming. Regarding that, parametricism seems an effective way of managing /creating complex topologies in form-related issues. However, when it comes to practice, there are some challenging points of parametricism in large-scale design studies. Thus, this work underlines that the dominance of elegance for urban planning has the potential of limiting the flexible and dynamic topology of the urban context, and objectifying the whole complex urban form as an over-designed product. For an aesthetic inquiry into urban parametricism, this paper highlights the challenging issues behind the aesthetic premises of parametricism at the urban design scale. For that, Kartal Master Plan Design Proposal by Zaha Hadid Architects (2006) will be discussed as an exemplary work.

summary	The complex nature of architecture requires often planning teams with specialists from multiple disciplines. Architectural education however, addresses this interdisciplinary modus operandi rarely. This paper presents the design and production process of a real world solar façade installation realized at the University of Kassel to illustrating the potentials of such an approach. Interdisciplinary teamwork allowed students not only to solve complex problems, but also to produce knowledge and to advance into design research. Student exploration resulted in a unique fabrication technique, combining tensile fabric and resin to facilitate the fabrication of multifunctional, monocoque shells; combining all necessary technical components in a single building element. This paper discusses the success of student collaboration and teaching strategies for key parts of the design process at different scales. Moreover, it highlights the importance of physical form-finding models and an analogue - digital workflow for collaborative communication. The Free Skin project offers both insight into applied use of interdisciplinary teamwork, and a proposal for incorporating such collaboration into architectural education.

summary	Modern modular constructions can consist of highly indi- vidualised elements that are produced at nearly the same efficiency as serial manufacturing. This paper focuses on the project “WoodWaves” an Info-Point for the conference World Congress of Timber Engineer- ing, which was designed with this new conception of modularity. The process utilises a robotically operated milling cutter to form block- board panels out of spruce, which make up the multifunctional infor- mation point. The entire object is produced with only sliding dovetail joints. Parametric design methods were developed to automatically adjust each joint to fit the individual conditions. New CAD/CAM in- terfaces, linking design directly with fabrication, enabled the serial production of 108 different shaped elements with a 6-axis robotic arm.

title	Del microscopio electrónico a la estrategia digital en arquitectura [From the electron microscope to the digital strategy in architecture]

summary	The knowledge of when the amorphous masses of cells organize themselves into a first structural level is relevant for the architect. The architecture must also attend structural and economic stresses, following efficiency, as living beings do: something that we can learn from nature ("biolearning"), although that level can only be reached with microscope. So this becomes a useful tool for architectural research. Examples of this are presented here, seeking first to discover, analyze and evaluate microscopic structures of plants and animals. On that knowledge we can make emerge the digital design of real architectural projects, using computational strategies, also morphogenetic.

summary	This paper describes the design process behind Caress of the Gaze, a project that represents a new approach to the design of a gaze-actuated, 3D printed body architecture—as a form of proto-architectural study—providing a framework for an interactive dynamic design. The design process engages with three main issues. Firstly, it aims to look at form or geometry as a means of controlling material behavior by exploring the tectonic properties of multi-material 3D printing technologies. Secondly, it addresses novel actuation systems by using Shape Memory Alloy (SMA) in order to achieve life-like behavior. Thirdly, it explores the possibility of engaging with interactive systems by investigating how our clothing could interact with other people as a primary interface, using vision-based eye-gaze tracking technologies. In so doing, this paper describes a radically alternative approach not only to the production of garments but also to the ways we interact with the world around us. Therefore, the paper addresses the emerging field of shape-changing 3D printed structures and interactive systems that bridge the worlds of robotics, architecture, technology, and design.

title	Algorithmic Clustering of Spatial Entities - Clustering of 64 single rooms using the Self-Organizing Map algorithm
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 39-44
summary	Grouping spatial entities according to any kind of parameters has always been important both for practical and for theoretical purposes in architecture. For a long time, classification according to traditional reference systems was considered the only method to fulfil this purpose. However, in recent years, information technology has led to the hybridization and spread of design outputs, challenging the limits of applicability of these traditional reference systems and making it meaningless to refer to classification. This paper suggests the method of clustering spatial entities using user-defined reference systems. The method is demonstrated with a case study where 64 single rooms are clustered according to user-defined parameters with the use of the Self-Organizing Map. This method gives the power to the user to define and determine reference systems for the clustering of architectural projects according to their needs.

summary	Unlike any other building material, timber has seen numerous innovations in design, manufacturing, and assembly processes in recent years. Currently available technology not only allows architects to freely shape building elements but also to define their micro- or macroscopic material make-up and therefore the material itself. At the same time, timber shells have become a focus of research in wood architecture by rethinking both construction typologies and material application. Their main advantage, however, also poses a challenge to its construction: As the shell is both the load-bearing structure as well as enclosure, its segmentation and the individual segment’s connections become increasingly important. Their complex and often differentiated geometries do not allow for standardized timber joints, and with decreasing material thickness, conventional connection techniques become less feasible. The research presented in this paper investigates textile strategies for the fabrication of ultra-lightweight timber shells in architecture. Specifically, a robotic sewing method is developed in conjunction with a computational design method for the development of a new construction system that was evaluated through a large-scale prototype building.

title	Parametricism vs Materialism - Evolution of digital technologies for development

summary	We build on previous technological developments in CAAD by looking into parametric design exploration and the development of the concept of parametricism. We use the phenomenological backdrop to account for our physical experiences and encounters as well as our mental ones; both evident in the link between parametric design as a process and an outcome. In specific, we previously examined two particular metaphors. The first metaphor addressed aspects of virtual environments that resemble our physical world; In other words, computer model as physical model and digital world as material world. In this volume, we extend the exploration into aspects of virtual environments and their resemblance to physical environments by looking at ‘performance’ aspects: the way in which environments are sensed, measured, tracked and visualised. Moreover, we reflect on matters and materiality in both virtual and physical space philosophically, theoretically, practically and reflectively. The second metaphor looked into the modes and means of interaction between our bodies and such virtual environment. Here we extend the investigation to look at the ways in which measures of environmental performance influence human interaction in real environments. The exploration takes us further to look into the area of design fabrication of the built environment, and methods in which developed processes meet environmental performance requirements, and the innovative outcomes that lead to disruptive technologies getting introduced into design and we revisit parametric design under this focus area.

title	Exploring Weaire-Phelan through Cellular Automata: A proposal for a structural variance-producing engine
source	SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016, pp.710-714
summary	Complex forms and structures have always been highly valued in architecture, even much before the development of computers. Many architects and engineers have strived to develop structures that look very complex but at the same time are relatively simple to understand, calculate and build. A good example of this approach is the Beijing National Aquatics Centre design for the 2008 Olympic Games, also known as the Water Cube. This paper presents a proposal for a structural variance-producing engine using cellular automata (CA) techniques to produce complex structures based on Weaire-Phelan geometry. In other words, this research evaluates how generative and parametric design can be integrated with structural performance in order to enhance design flexibility and control in different stages of the design process. The method we propose was built in three groups of procedures: 1) we developed a method to generate several fits for the two Weaire-Phelan polyhedrons using CA computation techniques; 2) through the finite elements method, we codify the structural analysis outcomes to use them as inputs for the CA algorithm; 3) evaluation: we propose a framework to compare how the final outcomes deviate for the good solutions in terms of structural performance and rationalization of components. We are interested in knowing how the combination of the procedures could contribute to produce complex structures that are at the same time certain rational. The system developed allows the structural analysis of structured automatically generated by a generative system. However, some efficient solutions from the structural performance point of view do not necessarily represent a rational solution from the feasibility aspects.

summary	This paper expounds the teaching strategies used to introduce architecture students in the craft of design in the course Taller de Proyecto 1. These strategies are based on experiential mappings constructed from different digital resources allowing constantly confront design with real life, in order to maintain, throughout the process, a sensitive and precise relationship between reality and experience. It concludes that these methodologies strengthen the autonomy of students, developing a valuable reconnection with the way they look and transform the world, validating the premise that the act of design is an innate human act and not necessarily an erudite one.

title	What Bricks Want: Machine Learning and Iterative Ruin

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	This paper discusses the development of an interactive and a responsive Tangible User-Interface (TUI) for parametric and Building Information Modeling (BIM) applications. The prototypes presented in this paper utilizes physical computing systems to establish a flexible and intuitive method to engage digital design processes.The prototypes are hybrid UIs that consist of a digital modeling tool and an artifact. The artifact consists of a control system (sensors, actuators, and microcontrollers) and physical objects (architectural elements). The link between both environments associates physical objects with their digital design information to assist users in the digital design process. The integration of physical computing systems will enable the objects to physically respond to analog input and provide real-time feedback to users. The research aims to foster tangible computing methods to extend the capabilities of digital design tools. The prototypes demonstrate a method that allows architects to simultaneously interact with complex architectural systems digitally and physically.
