summary	Natural load bearing structures are characterized by aspects of specialized morphology, lightweight, adaptability, and a regenerative life cycle. PolyBrick 2.0 aims to learn from and apply these characteristics in the pursuit of revitalizing ceramic load bearing structures. For this, algorithmic design processes are employed, whose physical manifestations are realized through available clay/porcelain additive manufacturing technologies (AMTs). By integrating specialized expertise across disciplines of architecture, engineering, and material science, our team proposes an algorithmic toolset to generate PolyBrick geometries that can be applied to various architectural typologies. Additionally, comparative frameworks for digital and physical performance analyses are outlined. Responding to increasing urgencies of material efficiency and environmental sensibility, this project strives to provide for designers a toolset for environmentally responsive, case-specific design, characterized by the embedded control qualities derived from the bone and its adaptability to specific loading conditions. Various approaches to brick tessellation and assembly are proposed and architectural possibilities are presented. As an outcome of this research, PolyBrick 2.0 is effectively established as a Grasshopper plug-in, “PolyBrick” to be further explored by designers.

title	Reinterpreting Zellige Tiles through Ceramic 3D Printing
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 166-186.
summary	The intricate details of Zellige tile work in Islamic architecture have high cultural significance and important sacred associations. The quasi-crystalline geometry found in el Attarine Madrassa Zellige patterns are a splendid example of the geometric rigour and exceptional craftsmanship of these sacred decorations. Modern methods have been used to reproduce these complex patterns, but these methods are mostly focused on duplication, rather than contributing to the analysis and re-contextualization of these motifs. Where recent studies have investigated the tectonics and structural limitations of ceramic additive manufacturing, few have explored its unique capabilities of re-interpretation and abstraction. This paper investigates the Zellige tiles of el Attarine Madrassa in Fes through formal and tectonic prototyping via clay 3D printing. Adjustments to the pattern by twisting, shifting, and shrinking were evaluated to observe what new interpretations additive manufactured ceramics can provide to the reading of the pattern at an architecture scale. In parallel, custom tool path design strategies were developed to address the unique intersection and overlapping issues that resulted from the intricate linework of the mosaic’s geometric pattern. Several full-scale physical prototypes were developed to assess the success and design opportunities of each strategy. Design iterations were also conducted to develop a key stone assembly sequence while also testing assembly tolerances and bonding between component units. Lastly, a dome mosaic assembly was designed for an arbour structure to evaluate the architectural implications of the developed tile system. The objective is for this 3D printed investigation to simultaneously honour and innovate upon the rich continuum of craft tradition, culture, embodied knowledge, and spirit within these geometries.

title	Support-strategies for Robocasting Ceramic Building Components
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 377–386

summary	The introduction of ceramic additive manufacturing technologies in the building industry offers unprecedented opportunities to architects and engineers towards a new brick-architecture. Robocasting appears as a suitable technology to produce the medium- to large-scale components needed for building applications. This process involves deploying individual strands of clay layerwise to form an object. Unlike powder-bed or sheet-lamination-processes, robocasting does not come with a process-inherent support-material. Using support-material increases the range of producible geometries and therefore is a crucial necessity to exploit the technology. In this paper, first the limits of the unsupported process were identified. Also, a representative architectural component, which included overhangs, bridged areas and arcs was designed generatively. In the first stage, its geometry was derived from the material-related limitations of the used clay. Next, different strategies to exceed the process-related limitations have been developed and tested. The results are discussed and an overview of these counteractions and their applicability is provided. Ultimately, the representative architectural component was fabricated once again, with a geometry exceeding the geometric limitations by applying the support-strategies that were developed beforehand.

title	BIM and the Building Site: Assimilating digital fabrication within craft traditions
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. 27-36
summary	This paper outlines a particular component of very well known project: Antoni Gaudí’s Sagrada Família Basilica in Barcelona (1882– on-going but scheduled for completion in 2026). At the time of writing the realisation of the project has proceeded for 87 years since Gaudí's death (1852-1926). As a building site it has been a living laboratory for the nexus between traditional construction offsite manufacturing and digital fabrication since the computers were first introduced to the project:CAD in 1989 closely followed by CAAD two years later. More remarkably CAD/CAM commenced its significant influence in 1991 with the take-up of sem robotised stone cutting and carving. The subject of this paper is an elevated auditorium space that is one of the relatively few ‘sketchy’ areas that Gaudí bequeathed the successors for the design of his magnum opus.

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 paper discusses a case study for a seating element that takes into account human factors as well as aspects of structural performance, material properties and production parameters within an integrative design approach. Generico is a prototype for a new way of design thinking, developed with a holistic approach. The design is based on the requirements of comfortable sitting and responds to load forces and ergonomic conditions. The Generico chair – resulting from an all-embracing line of thought, from design to production, is an ideal field of application for 3D-printing-technology as it allows for an optimal material distribution.

summary	"The introduction of digital tools in the production of architecture undoubtedly constitutes the main force behind contemporary architectural innovation. In addition, the interaction of digital technologies with analog craft manufacturing -a rather unexplored field of study- suggests a wide range of novel opportunities. This research focuses on developing a framework for deploying digital design techniques to the production of bricks under vernacular technology as a medium of achieving geometrical variations and functional complexity in domestic-scale projects. Solid clay bricks are embedded in traditional ceramic-construction culture. Thus, this investigation faces the challenges of making a feasible innovative system in a country where digital fabrication is not an economically viable option, and engaging a design that can be easily implemented with current hand-labour. Consequently, the new bricks would be massively introduced in the construction market, allowing novel formal and functional possibilities for designers.

summary	According to Hod Lipson at Cornell University’s Creative Machines Lab, cloud manufacturing ‘consists of a network of smallscale, decentralized nodes of production.’ It is a novel production approach relative to centralized mass production and standardisation methods common to today’s industrial processes. To date, cloud manufacturing techniques have focused largely on the production of smallscale consumer goods that integrate digital fabrication techniques, the most popular being 3D-printing technology. With advances in network-based design platforms for 3D-printing services in combination with the global installation of fabrication laboratories (fab lab), the production of architectural building components using cloud manufacturing techniques is now possible. This paper will define how cloud manufacturing techniques can be expanded into the realm of architectural practice and, in particular, how such techniques can be applied to larger-scale building and construction components. The paper will further discuss how such novel additive manufacturing (AM) processes applied to construction can potentially revolutionize architectural design by generating a new collaborative design model that facilitates local production of customized and readily assembled building components on demand.

summary	The need for increased automation of the AEC sector has been extensively documented within the architectural discipline over recent years. Far beyond economic perspectives, current advances in technology offer an increased and more direct implementation of sustainable materials. Within this research, the potential for the re-use of material with low embodied energy within automated construction will be examined. Herefore, Remote Material Deposition (RDM, firstly described in Dörfler et al., 2014) is utilized as main fabrication method, deploying varying compositions of local building debris, lime mortar, and sand, via a throwing arm. This research explores a method of continuous verification of material deployment and removal of material oversaturation to guarantee accuracy. Herefore, all instances of the robot ecology are in direct communication with one another and the user for verification, adaptation, and information. The proposed framework is examined through experimentation by designing, building, and implementing an inter-communicative network of bespoke semi-autonomous robots with all proposed parts of the system.

summary	This paper proposes strategies for performance-based architectural devices characterized by a distinct material exuberance.The engineered predictability of typical building systems is challenged in favor of biological performance modes ruled by scales, sweat, and curves rather than shipping, manufacturing, and commerce. In the realm of traditional ceramic hand- making and manufacture, computation and CNC fabrication are two powerful tools which position the craftsman at the helm of a hybrid endeavor for smart materials.

summary	Additive Manufacturing (AM) offers the potential development of novel architectural applications of ceramic building components that can be engineered at the level of material to the extent of designing its performance and properties by density variations. This research presents a computational method and fabrication technique emulating complex material behavior via AM of intricate geometries and presents components with photocatalytic and climatic properties. It proposes an innovative application of AM of ceramic components in architecture to explore potential bioclimatic and antipollution performative use. Lattices are defined and manufactured with density variation gradients by tracing rectilinear clay deposition toolpaths that induce porosity intended for fluid filtering and to maximize sun exposure. The design method for photocatalytic, particle filtration and evaporative cooling local characterization introduced by complex patterning elements in architectural envelope slat components processed with radiation analysis influenced design are validated by simulation and experimental testing on specimens manufactured by paste extrusion.

This paper presents a computational design method developed for 3D printing of unique interlocking ceramic components, which assemble into segmented columns. The fabrication method is ceramic-paste extrusion, robotically placed on semi-cylindrical molds. Material system and fabrication setup contribute to the development of an integrated generative system which includes overall design, assembly logic and printing tool-path. By contextualizing clay extrusion and identifying challenges in bespoke tool-path generation, this paper discusses detailing opportunities in digital fabrication. Finally, it identifies future directions of research in extrusion-based printing.

summary	The concrete industry is responsible for 8% of the global CO2 emissions. Therefore, using concrete in more complex and optimized shapes can have a significant benefit to the environment. Digital fabrication with concrete aims to overcome the geometric limitations of standardized formworks and thereby reduce the ecological footprint of the building industry. One of the most significant material economy potentials is in structural slabs because they represent 85% of the weight of multi-story concrete structures. To address this opportunity, Fast Complexity proposes an automated fabrication process for highly optimized slabs with ornamented soffits. The method combines reusable 3D-printed formwork (3DPF) and 3D concrete printing (3DCP). 3DPF uses binder-jetting, a process with submillimetre resolution. A polyester coating is applied to ensure reusability and smooth concrete surfaces otherwise not achievable with 3DCP alone. 3DPF is selectively used only where high-quality finishing is necessary, while all other surfaces are fabricated formwork-free with 3DCP. The 3DCP process was developed interdisciplinary at ETH Zürich and employs a two-component material system consisting of Portland cement mortar and calcium aluminate cement accelerator paste. This fabrication process provides a seamless transition from digital casting to 3DCP in a continuous automated process. Fast Complexity selectively uses two complementary additive manufacturing methods, optimizing the fabrication speed. In this regard, the prototype exhibits two different surface qualities, reflecting the specific resolutions of the two digital processes. 3DCP inherits the fine resolution of the 3DPF strictly for the smooth, visible surfaces of the soffit, for which aesthetics are essential. In contrast, the hidden parts of the slab use the coarse resolution specific to the 3DCP process, not requiring any formwork and implicitly achieving faster fabrication. In the context of an increased interest in construction additive manufacturing, Fast Complexity explicitly addresses the low resolution, lack of geometric freedom, and limited reinforcement options typical to layered extrusion 3DCP, as well as the limited customizability in concrete technology.

summary	Worldwide we produce billions of tonnes of waste per year, including a million tonnes of plastic waste. Currently, there are methods for recycling plastic, but these methods can be expensive and time-consuming, resulting in most of the plastic being thrown into the landfill. Because plastic does not fully degrade, it ends up in the ocean and other waterways, poisoning the water with toxins. The purpose of this research is to provide a solution to reducing plastic waste by creating an alternative method of recycling that utilises new technologies such as additive manufacturing, to create a building material that fits into the concept of the circular economy. The findings of this research explored the recycling of plastic by collecting plastic waste such as PLA (Polylactic Acid) from old 3D printed models and other sources. The plastic was recycled into filament for additive manufacturing (AM) and used to print a building component, establishing a foundational proof of concept for the use of recycled plastic as a potential building material.

summary	The use of Additive Manufacturing (AM) for the production of architectural components has more and more examples attesting the possibilities and the advantages of its application. At the same time we seen a fast grow of the usage of ceramic materials to produce fully customised architectural components using Layer Deposition Modelling (LDM) [1] techniques. However, the use of this material, as paste, leads to a series of constraints relative to its behaviour when in the viscous state, but also in the drying and firing stages. Thus, when ceramic dries, the retraction effects may be a barrier to the regular use of this material to build future architectural systems. In this sense, it is important to study the material behaviour and know how to control and use it as a primary construction material. To do that we present the challenges and outcomes of project Hexashade, a ceramic vault shading system prototype whose geometry and internal structure is defined according to the solar incidence. This paper explain how we expect to build a real scale self-supporting prototype.

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	Emerging regulations in the context of sustainability have placed renewed attention on construction protocols, including consideration of end-of-life, waste reduction and a shift to bioplastics. However, much research is required on the integration and compatibility of bioplastic materials and their performance concerning construction industry standards. Parallel to the material perspective, increased efforts are placed on additive manufacturing (AM) processes in architectural design and their potential contribution to sustainability through experimentation with new materials, enhanced performance prototyping and reduction in material use. Within this context, the following paper develops a framework towards large-scale additive manufacturing examining bioplastic compounds for architectural components with acoustic performance. A design workflow outlines the component geometry and micro-structuring for both scattering and absorption. It explores the ability to expand on the acoustic behaviour of the chosen materials through printing techniques such as pull printing, fiber printing and dynamic structure printing, within a robotic FDM setup utilizing non-planar tool path design. The robotic workflow developed, outlines a material-informed calibration of bioplastic compounds, their predicted acoustic compatibility to the construction industry, and highlights the potential of such AM workflows to align with current sustainability goals.

summary	We introduce a promising proof of concept: a blockchain to additive manufacturing pilot prototype. In this paper we focus on developing the functional cyberphysical prototype of the smart contracts running on a blockchain, orchestrating the workflow of additive manufacturing in architecture. We have used design science research and rapid prototyping as methods to create our cyberphysical system. Our prototype allows for the discretisation of a design in components, which are then placed for bidding for production. The components are indexed, with a Non-Fungible Token is produced for each component, recorded on the smart contracts of our platform. The original designers are recorded and then rewarded if the component is ever re-used. A set of additive manufacturing shops then cost and bid for the production of the components, recording their bid on-chain. Component fabrication quality is then validated against the tamper-proof blockchain storage system. Our pilot project establishes viability and a direct link between a blockchain network and 3D printers, facilitated by microcontrollers interfaces acting as blockchain “Oracles”. The significance of this paper lies in its potential to reshape the architectural manufacturing and fabrication landscape. By integrating blockchain with 3D printing, we address critical issues such as efficiency, in challenging locations with labour shortages or logistical constraints.

summary	The research presented in this paper investigates the development of "3D printed ceramic green wall", a technological Nature Based Solution (NBS) aimed at regenerating urban areas by improving spatial quality and sustainability through clean and autonomous energy production. Building upon previous research, the challenge of this system is to adapt additive manufacturing processes of ceramic 3D printing with biophotovoltaic systems while simultaneously developing digital and cyber-physical frameworks to generate site and user responsive design and autonomous solutions that optimize system performance and energy generation. The paper explores the complex design negotiations between these drivers, focusing particularly on their performance optimization, and finally highlights the system potential as exemplified through a successful implementation of a 1:1 site responsive wall prototype.
