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.

title	Aerodynamic strategy applied in an urban shelter design - Simulation and analysis of aerodynamic phenomena in an urban context
doi	https://doi.org/10.52842/conf.ecaade.2014.1.137
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 137-144
summary	This paper presents an experimental study on strategies of utilizing wind as an architectural element, proposing the reconfiguration and projection of wind patterns to produce vaults of wind as regions of shelter in the outdoor environment. It shows an aerodynamic analysis and exploration of barriers, deflectors and porous screens in an existing urban wind canyon for a hypothetical urban shelter in a tram stop area. Computational Fluid Dynamics (CFD) software and physical tests in a wind tunnel using microelectronic hot-wire anemometry are the methods utilised. The experiments involve a comparison between screens with impermeable surfaces and porous membranes and their ability to project wind as architecture. The experiments showed that the use of porous membranes improves the mitigation level of wind speed and turbulence intensity in the wind vaults regions.

title	Wind sensing with real-time visualisations for Designers - An approach to understanding wind phenomena for pedestrian comfort using low cost wind sensors
doi	https://doi.org/10.52842/conf.ecaade.2014.1.165
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 165-171
summary	The evaluation of a low-tech wind sensing platform for urban aerodynamic simulations relevant to pedestrian comfort. In this paper, the wind canyon effect is simulated with two different building morphologies. The platform provides conceptual knowledge of the dynamics in wind relevant for designers, architectural practitioners and students of design. Low-cost hot wire anemometry is utilised for the design of an Experimental Fluid Dynamic (EFD) wind sensing network interface. This paper explores the validity of the sensing platform for a new approach for non-wind engineers to gain a better understanding of the dynamics of wind. The influence of real-time feedback from quantified wind on the understanding of wind phenomena for non-wind engineers is discussed and compared with post analysis data. It was found that real-time quantified feedback from wind intrigues and stimulates the intuitive notion of wind dynamics through discussion, however post analysis remains critical to evaluate building design performance.

title	A Framework for Input Data Processing During Building Energy Model Calibration. A Case Study
doi	https://doi.org/10.52842/conf.ecaade.2015.1.625
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 625-634
summary	Key parameter of a reasoning process supporting real time performance is the use of active heuristics that facilitate the achievement of goals in a timely manner (Dodiawala et al. 1989). A real time approach should incorporate speed, timeliness and adaptation during the execution of tasks. Speed and efficient knowledge processing are addressed for the solution of complex building engineering problems, such as the calibration of Building Energy Models (BEM) to the actual performance data. During retrofit projects, calibrated BEM models aid the design process, and provide a solid base for performative assessments. Despite the demand for building performance evaluations, BEM calibration remains a work-intensive task (Lam et al. 2014). This study proposes a time efficient framework for BEM calibration input data management based on the methodology of a blackboard artificial intelligence knowledge processing system. The resulting model was used for sequential data mining for the energy assessment during the renovation of a commercial building.

title	Approximating Computational Fluid Dynamics for Generative Tall Building Design
source	International Journal of Architectural Computing vol. 12 - no. 2, 155-178
summary	Background literature review, methodology, results, and analysis are presented for a novel approach to approximating wind pressure on tall buildings for the application of generative design exploration and optimisation.The predictions are approximations of time-averaged computational fluid dynamics (CFD) data with the aim of maintaining simulation accuracy but with improved speed.This is achieved through the use of a back-propagation artificial neural network (ANN) with vertex-based shape features as input and pressure as output.The training set consists of 600 procedurally generated tall building models, and the test set of 10 real building models; for all models in both sets, a feature vector is calculated for every vertex. Over the test set, mean absolute errors against the basis CFD are 1.99–4.44% (_:2.10–5.09%) with an on-line process time of 14.72–809.98s (0.028s/sample). Studies are also included on feature sensitivity, training set size, and comparison of CFD against prediction times. Results indicate that prediction time is only dependent on the number of test model vertices, and is therefore invariant to basis CFD time.

summary	In this paper we present an outline of a newly started project to develop a tool which connects BIM to a manufacturing technique like 3D printing. First we will look some promising manufacturing techniques. We will design a small dwelling and export it into a BIM, from which we will extract our data to generate the path the nozzle has to follow. The chosen path is constrained by the material properties, the design and speed of the nozzle. To validate the system we develop a small VR tool in which we mimic a manufacturing tool.

title	Intelligent Digital Craft to Recognize Spatial Installations for Residential Designs: Approach to Understand the Design of Housing Barbaric in Algeria using the Majali Composition Software
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 195-196; 443-456
summary	Architecture took an evolutionary context over time, where designers were interested in finding pragmatic spontaneous appropriate solutions and met the needs of people in urban and architectural spaces. Whereas, in modern architecture an intense and varied competition happens between architects through various currents of thoughts , schools and movements, however, that creativity was the ultimate goal , and a the same time we find that every architect distinguishes himself individually or collectively through tools of architectural expression and design representation adopting a school of thought, using , for example, the leaves of various sizes and diverse technical drawing tools to accurately show that he can be read by professionals or craftsmen outside the geographical scope to which it belongs .With the rapid technological development which accompanied the digital craft in the contemporary world , The digital craft summed up time, distance and tools , so they gave the concept more appropriate accuracy , as virtualization has become the most effective tool for Architecture To reach the ideal and typical results at the practical level, or pure research. At the level of residential design and on the grounds that housing plays an important role in the government policies and given that housing is a basic unit common to all urban communities on earth , the use of different programs to show its typicality in two dimensions or in the third dimension - for example, using software "AutoCAD " " 3D Max " , " ArchiCAD " ... etc. - gave virtualisation smart, creative and beautiful forms which lead to better understand the used /or to be used residential spaces, and thus the conclusion that the life system of dwelling under design or under study , as can specifically recognize spatial structure in housing design - using digital software applying "Space Syntax" for example - in the shadow of slowly growing digital and creative development with the help of high-speed computers . the morphological structure of the dwelling is considered to be the most important contemporary residential designs Investigation through which the researcher in this area aims to understand the various behavioral relations and social structures within the projected residential area, using Space Syntax techniques. Through the structural morphology of dwellings can be inferred quality networks, levels of connectivity and depth and places of openness or closure within the dwelling under study, or under design. How, then, have intelligently contributed this digital craft to the perception of those spatial fixtures ? The aim of this research is to apply an appropriate program in the field of vernacular residential design and notably Space syntax which relate to the understanding and analysis of spatial structures, and also demonstrate its role at the morphological and spatial structure aspects, and prove how effective it helps to understand the social logic of domestic space through social individual/collective relationships and behaviors projected on the spatial configurations of dwellings. The answer to the issue raised above and at the methodological aspect, the study discussed the application of space syntax techniques on the subject. The findings tend to prove the efficiency by comparing samples of Berber vernacular domestic spaces from the Mzab, the Aures and Kabilya in Algeria, and has also led to ascertain the intelligibility of space syntax techniques in reading the differences between the behaviors in domestic spaces in different areas of the sample through long periods of time .

title	A Survey on the Visual Communication Skills of BIM Tools
doi	https://doi.org/10.52842/conf.caadria.2014.337

summary	Building Information Modelling (BIM) applications are supported by various modelling tools, being expansive to deliver visualised geometry and databases simultaneously. But there is still a gap in visual communication amongst its professionals. Articulating the advantages of fully Web-based collaboration, this paper looks into how BIM tools make contribution to visual communication between different parties working collaboratively. A hybrid model of low-level and high-level interactions is tentatively conceptualised. Based on the hybridised model, a survey is conducted to elucidate a few experiential matters such as visual aesthetics, cognition and motivational impacts of visualisation in BIM tools. Following the survey, a discussion is oriented towards a new storytelling methodology with a novel term, namely gamification. Seeking motivating and efficient means of visual communication between human-human, human-tool and human-model interactions, the present study focuses on an enhanced legibility and appreciation of tools by those who are involved in BIM projects.

title	Ambiente de imersão virtual como ferramenta para mudança de paradigma no processo de projeto arquitetônico: da representação à interação [Virtual immersive environment as a tool for paradigm shift in architecturaldesign process: from representation to interaction]
source	SiGraDi 2014 [Proceedings of the 18th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-9974-99-655-7] Uruguay - Montevideo 12 - 14 November 2014, pp. 551-555
summary	This paper discusses the possibility of a low-cost immersive virtual environment (AIVITS) shifting the paradigm from representation to interaction in architecture design process. It first presents the perspectival paradigm in architecture, initiated in the Renaissance and culminating with the separation between design, building and use, having representation as its main product. Then it discusses the possibility of having representation as a tool, no longer as a paradigm, in a design process based on interaction. It then presents the interface used in the low-cost immersive virtual environment, which instead of representing the final appearance of the building, stimulates people to play with constructive possibilities by means of gestures.

summary	This article proposes to study the process of parametric design integrated analysis and structural design. This application model is called Performative Model; the form is generated based on performance criteria. The digital tools facilitate the information flow between designers using parametric model and Finite Element Analysis. To research the method of Performative Model is proposed the development of a conceptual framework of lattice wind tower with the aim of a quantitative and qualitative structure optimization. Therefore, the parametric modeling will be done using Rhinoceros software, the plugin for creating algorithms Grasshoper and structural analysis plugin Scan & Solve.

summary	The paper is premised upon the notion that tools and techniques have the potential to resist the premature prefiguring of problems and solutions in projectbased activity, with particular relevance in collaborative design practices. The architect’s métier and mode of knowledge production is marked by the capacity to make artefacts. Because our age is characterized by the imperative to innovate and evolve technically, architectural ideation must now engage an array of computationally-based tools for imaging, information management, simulation and fabrication. This paper, framed within the theoretical and productive context of a research-creation project, investigates the ontological status of process-work, speed, and the notion of failing fast through the prototyping of three small buildings, or shacks. It does this through a strategic choreography of factual and counterfactual investigations that give rise to fabricative knowledge incapable of being prescribed conceptually from the outset. It will be claimed that, in the case of architecture, the potential of technics to reflectively and playfully re-work things and ideas is also a participatory mode of ethical engagement.

summary	In this research, we develop the quantitative design analysis method for the atypical nose shape of bullet motif high-speed trains. And we trace the design changes and reveal the changes of design criteria that are shown in the evolutionary process of the Shinkansen high-speed trains by the quantitative method. To do this, first, we define the corpus of Shinkansen high-speed train designs. Second, the landmarks – sub-features – that comprise a nose shape of high-speed train are defined. Third, the locomotives of the corpus are quantitatively analysed by the morphometrics: a method of geometric shape analysis. Finally, the design changes are traced by the result of the analysis and the changes of design criteria will be revealed.

summary	This paper investigates the potential and implications of using naturally occurring material phenomena as a connecting mechanism for solid timber components. Proposed and discussed are connections based on anisotropic shrinkage and geometrical variability of trees. Using the notion of material agency in design, following the bio-cybernetic and biomimetic frameworks, solutions are devised to reduce energy usage, environmental pollution and utilise low-processed material. Finally, consequences of the fusion of the natural (analogue) and the digital realms are discussed, with an example of a workflow integrating inherent material traits with digital manufacture.

title	A CFD Analysis of the Urban Morphology Effect on Air Pollutants Dispersion
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 395-403
summary	Air pollution in urban environments can have negative consequences on people's health and comfort of city-dwellers, and on the durability of buildings. Understanding the transfer and deposition of pollutants in the urban environment is therefore essential in the design process of a building. Computational simulations can aid in understanding the pollutant/chemical dispersion in the urban cityscapes. Computational fluid dynamics (CFD) represents the study of fluid mechanics with the use of computer models and simulations. In this paper we study the impact of urban planning on pollution dispersion, the dispersion characteristics, such as the spread of the pollution dispersions, have been determined for different wind speeds and wind directions.

summary	The paper presents a novel approach on the design of complex forms by re-formulating the relationships between form, structure, material, fabrication and construction. It is proposed that current design models are supplemented by feedback-enabled frameworks, integrating material properties, fabrication constraints and construction logistics. As such, a series of input parameters based on industry standards, filtered through physical testing and digital simulations, feed a central computational model. The outcome is weighed against a set of objectives towards an optimum design solution which embodies construction logic while ultimately opposing costly inflated ad-hoc solutions. Within the above framework and as part of a broader research conducted at [ARC], this paper illustrates a design methodology implemented at the case study of 'God's Eye', winning entry of Sukkahville 2013 International Design Competition. It is further supported that a high tech, interdisciplinary design process based on efficient material assemblies allows for a complex, yet efficient end result, through low tech affordable construction.

summary	The integration of performance evaluation into the building design process becomes increasingly important in order to respond to demands on contemporary design with respect to the future of our built and natural environments. This paper presents work on the second iteration of an implementation of a design performance optimization framework that attempts to respond to the challenges of integrating analysis and optimization into the design process. Main challenges addressed are speed of feedback through implementation on the cloud, utilizing parallelization of computations and availability of results in the computational context of the model through leveraging the parametric nature of the application; The goal is to enable designers in their decision-making throughout the design process with focus on earlier phases of the design process during which changes can be implemented faster and at much lower costs than in later phases of design or even during construction and occupation.

summary	Recently more researches on tangible objects have been conducted that enhance the intuitive polygonal or surface modelling of designers in digital and physical worlds. However, a few researches have been done that augment the digital solid modelling with tangible objects. In this paper, we present the Augmented Solid Modeller (ASoM) which helps designers create more complex shapes by a combination of Boolean operations between a different type of 3D-printed tangible objects, which is different from the conventional single shape type bottom-up modelling approaches. When multiple objects intersect each other at a given position and angle, the interference or removed shape is often unexpected for designers. Also, as 3D-printed objects are used for designers only to configure and discuss the shape of final digital 3D model in existing CAAD, ASoM changes the role of 3D-printed objects from the replicas to reusable tools for other modelling opportunities. We offered ASoM to students majoring or interested in CAAD and interviewed them to get comments. Since the speed and precision of 3D-printing will achieve immediate improvement, ASoM is a pioneer in developing cutting-edge approach for designers to model both in digital and physical worlds.
