Structural optimization for materially informed design to robotic production processes

Hyperbody’s materially informed Design-to-Robotic-Production (D2RP) processes for additive and subtractive manufacturing aim to achieve performative porosity in architecture at various scales. An extended series of D2RP experiments aiming to produce prototypes at 1:1 scale wherein design materiality has been approached from both digital and physical perspectives were recently implemented. At digital materiality level, a customized computational design framework for compression only structures has been developed, which was directly linked to the robotic production setup. This has enabled the systematic study of physical materiality, which cannot be fully simulated in the digital medium. The established feedback loop ensured not only the development of an understanding for material properties in relation to their simulated and real behaviours but also allowed to robotically additively deposit and/or subtractively remove material in order to create informed material architectures at 1:1 scale.Architecture and The Built Environmen

Design to fabrication integration and material craftsmanship - A performance driven stone architecture design system based on material, structural and fabrication constraints and criteria

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.Architectural Engineering and TechnologyArchitecture and The Built Environmen

Data-driven architectural production and operation

Data-driven architectural production and operation as explored within Hyperbody rely heavily on system thinking implying that all parts of a system are to be understood in relation to each other. These relations are increasingly established bi-directionally so that data-driven architecture is not only produced (created or designed and fabricated) by digital means but also is incorporating digital, sensing-actuating mechanisms that enable real-time interaction with (natural and artificial) environments and users. Data-driven architectural production and operation exploit, in this context, the generative potential of process-oriented approaches wherein interactions between (human and non-human) agents and their (virtual and physical) environments have emergent properties that enable proliferation of hybrid architectural ecologies.Architectural Engineering +TechnologyArchitecture and The Built Environmen

Multi-scalar agent-based complex design systems - the case of CECO (Climatic -Ecologies) Studio; informed generative design systems and performance-driven design workflows

This paper illustrates the application of different types of complex systems for digital form finding and design decision making with underlying methodological and pedagogical aims to emphasize performance-driven design solutions via combining generative methods of complex systems with simulation techniques. The design research examples described in the paper are undertaken within the design studio titled CECO or Climatic-Ecologies, conducted at Hyperbody, TU Delft. The computational models explored within the studio include generative systems such as multi-agent system, cellular automata, recursive systems and L-system. The case studies presented in this paper show the early stages of the design development and the use of agent-based system at both macro, urban, scale to micro, architectural and structural scales, while considering environmental and local site conditionsArchitectural Engineering and TechnologyArchitecture and The Built Environmen

Informed Design to Robotic Production Systems; Developing Robotic 3D Printing System for Informed Material Deposition

This paper discusses the development of an informed Design-to-Robotic-Production (D2RP) system for additive manufacturing to achieve performative porosity in architecture at various scales. An extended series of experiments on materiality, fabrication and robotics were designed and carried out resulting in the production of a one-to-one scale prototype. In this context, design materiality has been approached from both digital and physical perspectives. At digital materiality level, a customized computational design framework is implemented for form finding of compression only structures combined with a material distribution optimization method. Moreover, the chained connection between parametric design model and robotic production setup has led to a systematic study of certain aspects of physicality that cannot be fully simulated in the digital medium, which then establish a feedback loop for underrating material behaviors and properties. As a result, the D2RP system proposes an alternative method of robotic material deposition to create an informed material architectureArchitectural Engineering and TechnologyArchitecture and The Built Environmen

Performance Driven Design and Design Information Exchange

This paper presents a performance driven computational design methodology through introducing a case on parametric structural design. The paper describes the process of design technology development and frames a design methodology through which engineering, -in this case structural- aspects of architectural design could become more understandable, traceable and implementable by designers for dynamic and valid performance measurements and estimations. The research further embeds and customizes the process of topology optimization for specific design problems, in this case applied to the design of truss structures, for testing how the discretized results of Finite Elements Analysis in topology optimization can become the inputs for designing optimal trussed beams or cantilevers alternatives. The procedures of design information exchange between generative, simulative and evaluative modules for approaching the abovementioned engineering and design deliverables are developed and discussed in this paper

Multi-angle data acquisition to compensate transducer finite size in photoacoustic tomography

In photoacoustic tomography (PAT) systems, the tangential resolution decreases due to the finite size of the transducer as the off-center distance increases. To address this problem, we propose a multi-angle detection approach in which the transducer used for data acquisition rotates around its center (with specific angles) as well as around the scanning center. The angles are calculated based on the central frequency and diameter of the transducer and the radius of the region-of-interest (ROI). Simulations with point-like absorbers (for point-spread-function evaluation) and a vasculature phantom (for quality assessment), and experiments with ten 0.5 mm-diameter pencil leads and a leaf skeleton phantom are used for evaluation of the proposed approach. The results show that a location-independent tangential resolution is achieved with 150 spatial sampling and central rotations with angles of ±8°/±16°. With further developments, the proposed detection strategy can replace the conventional detection (rotating a transducer around ROI) in PAT.ImPhys/Medical Imagin
