title Ceramic AM Gantry Structures - Discretisation and connections between beams and columns

summary The manufacture of architectural components driven by digital design tools and Additive Manufacturing (AM) allows the achievement of highly evolved constructive systems, more integrated into a specific reality to which it is intended to respond, resulting in unique and adapted solutions with high geometric and material performances. Considering the application of these methods to common structural elements, namely beams and columns, for which there are already several examples demonstrating their feasibility, we find that it is necessary to provide a sound answer to an element that is fundamental for these proposals to function together as a single system - the moment of connection between beams and columns. In this sense, this paper proposes the design and test of a set of connections with adapted geometry between beams and columns, produced through ceramic Liquid Deposition Modelling (LDM), applying logics of topological optimization. This work foresees the development of a constructive system that incorporates reversible and irreversible connections, being formalised in a set of gantry structures formed by two vertical elements and a horizontal one, giving the comparative model between digital design and manufacture methods and the traditional ones.

summary This paper presents an approach for reusable formwork for thin-shell, double-sided highly detailed surfaces based on binder jet 3D printing technology. Using binder jetting for reusable formwork outperforms the milled and 3D printed thermoplastic formwork in terms of speed and cost of fabrication, precision, and structural strength against deformation. The research further investigated the synergy of binder jetting sandstone formwork with glass-fiber reinforced concrete (GFRC) to fabricate lightweight, durable, and highly detailed facade elements.We could demonstrate the feasibility of this approach by fabricating a minimal surface structure assembled from 32 glass-fiber reinforced concrete elements, cast with 4 individual formwork elements, each of them reused 8 times. By showing that 3D printed (3DP) formwork cannot only be used once but also for small series production we increase the field of economic application of 3D printed formwork. The presented fabrication method of formwork based on additive manufacturing opens the door to more individualized, freeform architecture.

summary Shellular Funicular Structures (SFSs) are single-layer, two-manifold structures with anticlastic curvature, designed in the context of graphic statics. They are considered as efficient structures applicable to many functions on different scales. Due to their complex geometry, design and fabrication of SFSs are quite challenging, limiting their application in large scales. Furthermore, designing these structures for a predefined boundary condition, control, and manipulation of their geometry are not easy tasks. Moreover, fabricating these geometries is mostly possible using additive manufacturing techniques, requiring a lot of supports in the printing process. Cellular funicular structures (CFSs) as strut-based spatial structures can be easily designed and manipulated in the context of graphic statics. This paper introduces a computational algorithm for translating a Cellular Funicular Structure (CFS) to a Shellular Funicular Structure (SFS). Furthermore, it explains a fabrication method to build the structure out of a flat sheet of material using the origami/ kirigami technique as an ideal choice because of its accessibility, processibility, low cost, and applicability to large scales. The paper concludes by displaying a structure that is designed and fabricated using this technique.

summary This paper examines the suitability of existing robotic technologies and large-scale 3D printing techniques for the fabrication of three-dimensional printed building components to be applied in the Saudi housing construction industry. The paper assesses a series of cases based on the applications for 3D-printing cement-based materials in construction. In particular, we investigate five different additive manufacturing techniques and evaluate their performance in terms of their flexibility/mechanism, control/navigation, calibration/operation system, fabrication suitability (in-situ or off-site), size of printed components, printing speed. The findings include in a matrix chart, where the advantages and disadvantages of each technique become evident. The paper further evaluates the suitability of each technique in relation to the particular climatical and socio-political context of Saudi Arabia, applicable to other construction industries with similar conditions.

summary The additive manufacturing process is gaining momentum in the construction industry with the rapid progression of large-scale 3D printed technologies. An established method of increasing the structural performance of concrete is by wrapping it with Fibre Reinforced Polymer (FRP). This paper proposes a novel additive process to fabricate a FRP formwork by dynamic layer winding of the FRP fabric with epoxy resin paired with an industrial scale robotic arm. A range of prototypes were fabricated to explore and study the fabrication parameters. Based on the systemic exploration, the limitations, the scope, and the feasibility of the proposed additive manufacturing method is studied for large scale customisable structural formworks.

summary This paper posits a design approach that integrates multi-agent generative algorithms and structural topology optimisation to design intricate, structurally efficient forms. The research proposes a connection between two dichotomous principles: architectural complexity and structural efficiency. Both multi-agent algorithms and Bi-directional evolutionary structural optimisation (BESO) (Huang and Xie 2010), are emerging techniques that have significant potential in the design of form and structure.This research proposes a structural behaviour feedback loop through encoding BESO structural rules within the logic of multi-agent algorithms. This hybridisation of topology optimisation and swarm intelligence, described here as SwarmBESO, is demonstrated through two simple structural models. The paper concludes by speculating on the potential of this approach for the design of intricate, complex structures and their potential realisation through additive manufacturing.

title Robotic 3D Printing of Mineral Foam for a Lightweight Composite Facade Shading Panel
doi https://doi.org/10.52842/conf.caadria.2021.1.603

summary This paper presents the design and fabrication of a lightweight composite facade shading panel using 3D printing (3DP) of mineral foams. Albeit their important role in industrial construction practice as insulators and lightweight materials, only little research has been conducted to use foams in 3DP. However, the recent development of highly porous mineral foams that are very suitable for extrusion printing opens a new chapter for development of geometrically complex lightweight building components with efficient formwork-free additive manufacturing processes. The work documented in this paper was based on preliminary material and fabrication development of a larger research endeavor and systematically explored designs for small interlocking foam modules. Furthermore, the robotic 3D Printing setup and subsequent processing parameters were tested in detail. Through extensive prototyping, the design space of a final demonstrator shading panel was mapped and refined. The design and fabrication process is documented and shows the potential of the novel material system in combination with fiber-reinforced ultra-high performance concrete (UHPC). The resulting composite shading panel highlights the benefits of using mineral foam 3DP to fabricate freeform stay-in-place formwork for lightweight facade applications. Furthermore, this paper discusses the challenges and limitations encountered during the project and gives a conclusive outlook for future research.

The paper presents an experimental framework for design, analysis and fabrication with 3DCP, developing a system for materializing interdependencies between geometry, material, performance.

summary The demand for sustainable building materials is currently a major concern of society. It is known that the traditional construction industry requires a high consumption of inorganic materials, which is associated with the excessive production of waste. Thus, this article intends to demonstrate the possibility of using the Additive Manufacturing (AM) technique Paste Extrusion Modeling (PEM) in the production of reusable, biodegradable and recyclable construction systems, using a combination of different natural materials that have created multiple pastes with different additives.Cellulose is a natural material - biodegradable, recyclable and low cost - and its implementation aims to change some aspects of the current state of the construction sector and can have a real impact on the exploration of innovative solutions and more sustainable alternative building systems. The integration of AM techniques, PEM method, supported by computational modelling tools, will allow the definition of a building system and its components. Depending on the material used - natural materials or biomaterials - the constraints and limitations of AM will be considered.

title Towards Self-shaping Metamaterial Shells: A Computational Design Workflow for Hybrid Additive Manufacturing of Architectural Scale Double-Curved Structures
doi https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_26
source Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)

summary Double curvature enables elegant and material-efficient shell structures, but their construction typically relies on heavy machining, manual labor, and the additional use of material wasted as one-off formwork. Using a material’s intrinsic properties for self-shaping is an energy and resource-efficient solution to this problem. This research presents a fabrication approach for self-shaping double-curved shell structures combining the hygroscopic shape-changing and scalability of wood actuators with the tunability of 3D-printed metamaterial patterning. Using hybrid robotic fabrication, components are additively manufactured flat and self-shape to a pre-programmed configuration through drying. A computational design workflow including a lattice and shell-based finite element model was developed for the design of the metamaterial pattern, actuator layout, and shape prediction. The workflow was tested through physical prototypes at centimeter and meter scales. The results show an architectural scale proof of concept for self-shaping double-curved shell structures as a resource-efficient physical form generation method.

summary This paper exploits passive responsive actuators as a passive approach for adaptive façades. The study encodes the embedded hygroscopic parameters of wood through 4D printing of laminated wooden composites as a responsive wooden actuator. Several experiments focus on controlling the printed hygroscopic parameters based on the effect of 3D printing patterns and infill height on the wooden angle of curvature. We present a set of controlled printed hygroscopic parameters that stretch the limits in controlling the response of wood to humidity instead of the typical natural properties of wood. The results show a passive programmed self-actuated mechanism that can enhance responsive façade design with zero energy consumption through utilizing both material science and additive manufacturing mechanisms. This passive responsive mechanism can be utilized in adaptive facades for dynamic shading configurations.

summary The structural properties of Fiber Reinforced Polymers (FRP) encourage designers and architects to use textiles as a load-bearing architectural material to create lightweight and strong structures. Manufacturing techniques of FRPs are mostly concentrated on the molding method. This method requires an extra mold fabrication that causes waste of material. This study focuses on integrative weaving and 3D printing fabrication methods, which emphasize the lightweight property of the material. This integrative method avoids excessive material waste during fabrication by using an additive approach. 3D printing on textiles prevents significant deformation in a specific direction of the fabric instead of using any kind of synthetic resin for stiffening the fabric. Additionally, structural behavior simulation allows designers to understand the different loading conditions and maximize the strengths of each textile design by adding more material where it is needed for possible architectural applications.

summary Additive Manufacturing in Construction (AMC) envisions a possible alternative for predominantly manual construction with various benefits. In addition to the well-known extrusion-based implementations of AMC, other techniques have been developed to meet various visual and functional requirement. However, the application of Additive Manufacturing (AM) into construction projects has to be carefully evaluated, especially during the early phases of architectural design when important decisions are made. From this point, this work devised an AMC-Oriented Design Decision Support System (DDSS) to identify suitable building components which can be manufactured with specific AM methods. In such a DDSS, knowledge base and decision-making strategy are both critical. To this end, principle of leveraging Semantic Web techniques and Multi-Criteria Decision Making (MCDM) methodologies will be addressed. At the current stage of our research, pre-printed building components using concrete material are considered during the decision support process.

summary Our awareness of the earth's depleting resources has directed focus towards biomaterials, which can be extracted sustainably and biodegraded after use. Current fabrication of biomaterial structures is still restricted in strength and geometry, limiting its use in construction. This paper presents a novel two-phase multi-material fabrication process to create mycelium composite structures of higher porosity and complexity with speculated improvements in strength. First, cellulose pulp inoculated with mycelium is extruded. Then, each layer is filled by a secondary supporting material. This material, in the form of a gravel- and sand-slurry, acts as an inhospitable medium steering mycelial growth, additionally improving aeration to produce stronger structures. After an intermediate growth period, the secondary material, reusable in a closed-loop production model, is removed to reveal the fully-grown mycelium structure. The paper reports on each of the three aspects: the fabrication process, material experimentation of primary and secondary substrates, as well as geometry of varying porosity and performance.

summary 3D printing offers significant geometric freedom and allows the fabrication of integral parts. This research showcases how robotic fused deposition modeling (FDM) enables the prefabrication of large-scale, lightweight, and ready-to-cast freeform formwork to minimize material waste, labor, and errors in the construction process while increasing the speed of production and economic viability of casting non-standard concrete elements. This is achieved through the development of a digital design-to-production workflow for concrete formwork. All functions that are needed in the final product, an integrally insulated steel-reinforced concrete wall, and the process for a successful cast, are fully integrated into the formwork system. A parametric model for integrated structural ribbing is developed and verified using finite element analysis. A case study is presented which showcases the fully integrated system in the production of a 2.4 m tall x 2.0 m curved concrete wall. This research demonstrates the potential for large-scale additive manufacturing to enable the efficient production of non-standard concrete formwork.

summary This paper presents a new additive manufacturing method for color grading of glass. Color-graded elements, ranging from product design to architectural scale, could filter light and view in a novel way through locally differentiated color and opacity, and produce color effects in space. Existing methods for manufacturing multi-colored glass are either not economic for building due to labor intensity, limited to surface applications or small scale objects made of resins or plastics. To allow for automated color grading of glass in two-and-a-half and three dimensions we propose a robotic multi-channel process. The multi-channel tool mounted on a Universal Robot consists of four compartments, containing red, yellow, blue and transparent glass granules. Colors can be mixed on the fly by implementing varying flow rate ratios along the print path. Loose granules are fused in a kiln at high temperature into color-graded glass elements. The goal of this research is to lay the basis for color-graded elements of larger size and volume with higher pattern differentiation for functional and aesthetic purposes.

summary Reconfigurable manufacturing systems (RMS), which have emerged with mass customization in the industry, allow the tool or system parameters to be adjusted in a controlled manner to produce customized products. Although the reconfigurable manufacturing systems have been applied in building and construction for waste, time, and cost reduction in producing specific mold forms at a prototype level, their utilization in additive manufacturing (extrusion) has not been explored. This paper presents, initial steps of ongoing research on the development of reconfigurable tools and workflow by transforming the tool's rigid parts with controlled parametric movable parts. The clay extruder tool used in crafts is transformed into a reconfigurable extruder tool that allows making customized forms. In the experimental setup, die combinations and tool head rotations are examined with the proposed Extrusion-based Making Grammar (EbMG). Produced forms illustrate the variations of the design space in relation to the rule sets. Here, a rule-based approach is found to be efficient for controlling the making parameters. This study explored the potentials of transforming a rigid craft tool into a customizable tool that allow the generation of product variation. It presents the preliminary stage of transforming craft tools into further digital craft tools.

summary Research in the field of additive manufacturing with concrete has gained enormous momentum in recent years. In practice, the first fully functional and habitable buildings have been realized. While these lighthouse projects have proven the general feasibility of 3D printing in construction, in the future it will be a matter of further expanding the potential of 3D printing, addressing important topics such as functional integration (reinforcement, piping, fasteners), material gradation (load-bearing, insulating) as well as disassembly and reuse.

As part of an international competition organized by LafargeHolcim Ltd. and its partners Witteveen & Bos, COBOD and Fondation des Ponts wich focused on realigning a traditionally manufactured residential building to concrete 3D printing technology, a team of students and researchers have developed a concept for a modular, function-integrated panel system for individualized wall and ceiling elements. The system is characterized by the fact that the integrated modular structures are printed flat on the floor and precise connections and structural joints are subtracted while the concrete is still in its green state.
