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)
doi https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
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 The recent convergence of computational design and digital fabrication has made new forms of architectural materialization possible. A workshop conducted at the Royal Melbourne Institute of Technology investigated how differentiated lightweight metal structures may be designed and fabricated under these new conditions. The workshop aim was to complete three such structures; each one is aggregated from aluminum profiles that are robotically assembled according to computationally driven geometric logics. The key challenge was to enable participants, assumed to lack programming and robotic fabrication experience, to design and construct their structures within imposed time constraints. This paper describes the subsequent development of accessible computational design tools and a robust robotic fabrication method for the workshop, and highlights the key decisions taken with their implementation. The workshop results are discussed and the design tools evaluated with respect to them. The paper concludes by recommending an approach to developing computational design tools which emphasizes the importance of usability and integration with the fabrication process.

summary This paper presents a computational design methodology through describing of a case study on stone building system. In addition to establishing a performance driven form-finding methodology, the objective is to redefine local craftsmanship methods as industrial fabrication techniques in order to introduce the constructability of the design solutions as one of the main performance criteria. Therefore, the focus of the methodology is to facilitate architectural design processes through developing of customized computational design tools and workflows for data integration and concurrent performance evaluation. The research starts with the hypothesis that the technological advancements in digital design and fabrication can lead to re-exploration and improvement of traditional building techniques with local materials. The paper explains different stages of the methodology and the way the chained design to fabrication processes would lead to constructible, structurally possible and optimal design solutions of small scale and simple symmetric design solutions to complex topologies at the scale of larger complex buildings.

title Embodied Design Cognition: Action-Based Formalizations in Architectural Design
source International Journal of Architectural Computing vol. 12 - no. 4, 399-418
summary This paper frames design knowledge as formalizable physical actions that can more fully exploit future design tools and production methods.As computational design tools become more physically interactive and integrated into our environment we need new research frameworks to develop theories of physical design action as a form of knowledge. Symbolic theories of design knowledge traditionally frame design activity as a mental process and as a result researchers have not fully explored the potential for bodily-based computational design knowledge.We present an action- based design notation drawing inspiration from music performance theory to illustrate how this may impact design research.We discuss findings from situated cognition in cognitive science as an alternative framework for exploring and expanding design knowledge.We conclude with suggestions for future work in robotic-aided design cognition.

title Treliças espaciais metálicas: combinação de parâmetros formais e materiais nos estágios iniciais do processo de projeto [Spatial steel trusses: Integrating structural pre-dimensioning requirements in the early stages of the parametric design]
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. 355-359
summary The integration of structural considerations in architectural geometry processing is among the topics most discussed in the complex shapes design. While some design tools allow the designer to begin with an inefficient form and then turn it into a more efficient one, other tools allow exploring and creating structural forms considering both formal and structural aspects from the beginning. This paper presents a parametric design approach to create spatial steel trusses with the combination of two strategies: (1) shell surface to set out structural elements; (2) cross section properties to ensure structural stability aspects. In this paper we discuss how the combination of these strategies can contribute to the use of parametric design techniques in the early stages of the design process, taking into account both structural optimization and production aspects.

summary The "PURE Tension" Pavilion is a lightweight, rapidly deployable, tensioned membrane structure and portable charging station commissioned by Volvo Car Italia to showcase the new Volvo V60 Hybrid Electric Diesel car. Officially launched in Milan, Italy in October 2013, this experimental structure was developed through a process of rigorous research and development that investigated methods of associative modelling, dynamic mesh relaxation, geometric rationalization, solar incidence analysis, membrane panelling, and material performance. It is an experimental structure that, similar to a concept car, is a working prototype that speculates on the potential future of personal mobility and alternative energy sources for transportation while also exploring digital design methodologies and innovative structural solutions. This paper will illustrate the design, development and fabrication processes involved in realizing this structure.

summary In an increasingly technological, informed and demanding society Architecture should be able to answer to its space requirements using materials and technological resources that today has at its service. Kinetic systems have been used by architects as an approach that embeds computation intelligence to create flexible and adaptable architectural spaces according to users’ changing needs and desires. This paper describes one possible way of exploring kinetic systems to develop a foldable surface with geometric patterns based on the rules of rigid origami. This surface aims to take advantage of the elastic capacities given to a planar material by its folding. After folding the surface can assume different forms in order to create a range of spatial configurations ordered by a user through a remote control.

summary project 3xLP, the winning submission to the TEX-FAB SKIN competition, is a continuation of design research on the structural properties of textured stainless steel sheeting, which typically is used for skinning and other non-structural purposes. The team conducted performative analyses of the material, and verified the results through full-scale prototyping. Structural studies relied on scale shifts that began with molecular composition and culminated with large-sale geometric systems. The work provides evidence of the adaptability, rigidity, and high performance of thin-gauge, textured metals; it establishes the groundwork for new structurally-based design possibilities using sheet steel.

title Surface Dynamics: From dynamic surface to agile spaces

summary Behavior, adaptation and responsiveness are characteristics of live organisms; architecture on the other hand is structurally, materially and functionally constructed. With the shift from ‘mechanical’ towards ‘organic’ paradigm (Mae-Wan Ho, 1997) attitude towards architectural adaptation, behavior and performance is shifting as well. This change is altering a system of reference and conceptual basis for architecture by suggesting the integration of dynamics – dynamics that don’t address kinetic movement only but include flows of energies, material and information. This paper presents an ongoing research into kinetic material system with the focus on non-mechanical actuation (shape memory alloy) and the structural and material behavior. It proposes an adaptive surface capable of altering its shape and forming small occupiable spaces that respond to external and internal influences and flows of information. The adaptive structure is developed as a physical and digital prototype. Its behavior is examined at a physical level and the findings are used to digitally simulate the behavior of the larger system. The design approach is driven by an interest in adaptive systems in nature and material variability (structural and functional) of naturally constructed materials. The broader goal of the research is to test the scale at which shape memory alloy can be employed as an actuator of dynamic architectural surfaces and to speculate on and explore the capacity of active and responsive systems to produce adaptable surfaces that can form occupiable spaces and with that, added functionalities in architectural and urban environments.

summary This research exhibits a novel construction method for Freeform surfaces with plywood, without using metal joints and bending. By introducing the perspective of Japanese Tsugite-Shiguchi, the research aims for a drastic change from node-oriented thinking to module-oriented thinking. This paper focuses on the investigation of how to simplify fabrication processes, how to realize the environmental capabilities of Freeform wood structures, and how to provide redundancy and stability to the whole architectural system. In order to challenge these problems, we examined three discretion methods. As a result, we have been successful to produce a double-layered surface, filled with triangular mesh, implemented only by cutting one sheet of plywood. Moreover, the system has also acquired a new nature: local-reconfigurability, wherein it can react and adapt to fit local parameters and requirements.

summary Several research projects (Gramazio et al. 2014; Willmann et al. 2015; Helm et al. 2017; Adel et al. 2018; Adel Ahmadian 2020) have investigated the use of automated assembly technologies (e.g., industrial robotic arms) for the fabrication of nonstandard timber structures. Building on these projects, we present a novel and transferable process for the robotic fabrication of bespoke timber subassemblies made of off-the-shelf standard timber elements. A nonstandard timber structure (Figure 2), consisting of four bespoke subassemblies: three vertical supports and a Zollinger (Allen 1999) roof structure, acts as the case study for the research and validates the feasibility of the proposed process.
