summary	Mycelium-based bio-composites can propose a renewable and biodegradable alternative for architectural construction materials. These biomaterials result from growth of mycelium, fibrous root systems of fungi, on organic substrates in controlled environmental conditions. This paper presents a material study that explores how substrate type and added supplements used for cultivating mycelium affect the compressive strength of mycelium-based composites for use as masonry units in architectural construction. For this purpose, samples grown using Pleurotus Ostreatus (Gray Oyster mushroom strain) on three different substrates (sawdust, straw and a mixture of sawdust and straw) with and without supplementation are tested for compressive strength.

title	Additive Manufacture of Cellulose Based Bio-Material on Architectural Scale
doi	https://doi.org/https://doi.org/10.1007/978-981-16-5983-6_27

summary	There are severe environmental and ecological issues once we evaluate the architecture industry with LCA (Life Cycle Assessment), such as emission of CO2 caused by necessary high temperature for producing cement and significant amounts of Construction Demolition Waste (CDW) in deteriorated and obsolete buildings. One of the ways to solve these problems is Bio-Material. CELLULOSE and CHITON is the 1st and 2nd abundant substance in nature (Duro-Royo, J.: Aguahoja_ProgrammableWater-based Biocomposites for Digital Design and Fabrication across Scales. MIT, pp. 1–3 (2019)), which means significantly potential for architectural dimension production. Meanwhile, renewability and biodegradability make it more conducive to the current problem of construction pollution. The purpose of this study is to explore Cellulose Based Biomaterial and bring it into architectural scale additive manufacture that engages with performance in the material development, with respect to time of solidification and control of shrinkage, as well as offering mechanical strength. At present, the experiments have proved the possibility of developing a cellulose-chitosan- based composite into 3D-Printing Construction Material (Sanandiya, N.D., Vijay, Y., Dimopoulou, M., Dritsas, S., Fernandez, J.G.: Large-scale additive manufacturing with bioinspired cellulosic materials. Sci. Rep. 8(1), 1–5 (2018)). Moreover, The research shows that the characteristics (Such as waterproof, bending, compression, tensile, transparency) of the composite can be enhanced by different additives (such as xanthan gum, paper fiber, flour), which means it can be customized into various architectural components based on Performance Directional Optimization. This solution has a positive effect on environmental impact reduction and is of great significance in putting the architectural construction industry into a more environment-friendly and smart state.

summary	In 2015, an earthquake of 7.8 magnitude displaced over 6.6 million people in Kathmandu, Nepal. Three years later, the country continues in its struggle to rebuild its capital. The aim of this study is to investigate a construction system, produced from locally sourced materials, that can aggregate and deploy as self-built, habitable infrastructure. The study focused on the relationship between material resonance, earthquake resistant structures, and fabrication strategies. An agent-based form-finding algorithm was developed using knowledge acquired through physical prototyping of mycelium-based composites to generate earthquake resistant geometries, optimize material usage, and enhance spatial performance. The results show compelling evidence for a construction methodology to design and construct a 3-4 story building that holds a higher degree of resistance to earthquakes. The scope of work contributes to advancements in bioengineering, confirming easy-to-grow, light-weight mycelium-composites as viable structural materials for construction.

summary	This article explains the evolution towards the subject of digital fabrication of thin shell structures, searching for the computational design techniques which allow to implement biological pattern mechanisms for efficient fabrication procedures. The method produces data sets in order to analyse and evaluate parallel alternatives of branching topologies, segmentation patterns, material usage, weight and deflection values as a user learning process. The importance here is given to the selection of the appropriate attributes, referring to which specific geometric characteristics of the parametric model are affecting each other and with what impact. The outcomes are utilized to train an Artificial Neural Network to predict new building information based on new combinations of desired parameters so that the user can decide and adjust the design based on the new information.

summary	This paper documents the design and fabrication process of modular responsive lighting installation. The design and research led to a modular and transformable urban lighting concept, combining unique material behaviour and cyber-physical system. The main goal was to investigate how material characteristics, composition and performance could be programmed in order to generate a range of modular components. Modular tiles and joints combination designed of sustainable materials - bioplastics and cork sheets - were created and used together with number of sensors and micro-controllers. Furthermore, the installation concept links technical and psychological aspects that potentially could be used for the benefits of city dwellers. Paper consists of two parts. First part is the introduction of a broader urban night lighting design context to which the project belongs. This includes covering existing social issues related to urban darkness, as well as the need to increase biodiversity within built environment, through introducing new materials. The second part of the paper describes the design and fabrication process, that employs the conclusions discovered in the first part through set of material experimentations, design project and the reflections on the results.

summary	Research investigating water-driven passive actuation demonstrates the potential to transform how buildings interact with their environment while avoiding the complications of conventionally powered actuation. Previous experiments evidence the possibilities of bi-layer materials (Reichert, Menges, and Correa 2015; Correa et al. 2015) and mechanical assemblies with discretely connected actuating members (Gupta et al. 2019). By leveraging changes in weather to power actuated building components these projects explore the use of smart biomaterials and responsive building systems. Though promising the implementation of these technologies requires deep engagement into material synthesis and fabrication. This paper presents the design and prototyping of a rain responsive faÃ§ade system using chitosan hygroscopic films as actuators counterbalanced by programmed compliant mechanisms. Building on previous work into chitosan film assemblies this research focuses on the development of compliant mechanisms as a means of controlling movement without over-complicated rotating parts.

summary	Buildings are responsible for 39% of global energy-related carbon emissions, with operational activities contributing 28% and materials and construction accounting for 11%(World Green Building Council, 2019) It is therefore vital to reconsider our reliance on fossil fuels for building materials and to develop new advanced manufacturing techniques that enable an integrated approach to material-controlled conception and production. The emergence of Multi-material Additive Manufacturing (MM-AM) technology represents a paradigm shift in producing elements with hybrid properties derived from novel and optimized solutions. Through robotic fabrication, MM-AM offers streamlined operations, reduced material usage, and innovative fabrication methods. It encompasses a plethora of methods to address diverse construction needs and integrates material gradients through data-driven analyses, challenging traditional prefabrication practices and emphasizing the current growth of machine learning algorithms in design processes. The research outlined in this paper presents an innovative approach to MM-AM gradient 3D printing through robotic fabrication, employing data-driven performative analyses enabling control over print paths for sustainable applications in both the AM industry and our built environment. The article highlights several designed prototypes from two distinct phases, demonstrating the framework's viability, implications, and constraints: a workshop dedicated to data-driven analyses in facade systems for MM-AM 3D-printed brick components, and a 3D-printed brick facade system utilizing two renewable and bio-materials—Cork sourced from recycled stoppers and Charcoal, with the potential for carbon sequestration.

summary	Despite, the innovation of additive manufacturing (AM) technology, and in spite of the existence of natural bio-materials offering notable mechanical properties, materials used for AM are not necessarily more sustainable than materials used in traditional manufacturing. Furthermore, potential material savings may be partially overshadowed by the relative toxicity of the material and binders used for AM during fabrication and post-fabrication processes, as well as the energy usage necessary for the production and processing workflow. Soil as a building material offers a cheap, sustainable alternative to non-biodegradable material systems, and new developments in earth construction show how earthen buildings can create light, progressive, and sustainable structures. Nevertheless, existing large-scale earthen construction methods can only produce highly simplified shapes with rough detailing. This research proposes to use robotic additive manufacturing processes to overcome current limitations of constructing with earth, supporting complex three-dimensional geometries, and the creation of novel organic composites. More specifically the research focuses on robotic binder-jetting with granular bio-composites and non-toxic binding agents such as hydrogels. This paper is divided into two main sections: (1) biodegradable material system, and (2) multi-move robotic process, and describes the most crucial fabrication parameters such as compaction pressure, density of binders, deposition strategies and toolpath planning as well as identifying the architectural implications of using this novel biodegradable fabrication process. The combination of soil and hydrogel as building material shows the potential of a fully reversible construction process for architectural components and foresees its potential full-scale architectural implementations.

title	Meeting in the middle: Hybrid clay three-dimensional fabrication processes for bio-reef structures
source	International Journal of Architectural Computing vol. 17 - no. 2, 148-165
summary	Despite the relative accessibility of clay, its low cost and reputation as a robust and sustainable building material, clay three-dimensional printing remains an under-utilized digital fabrication technique in the production of architectural artefacts. Given this, numerous research projects have sought to extend the viability of clay three-dimensional digital fabrication by streamlining and automating workflows through computational methods and robotic technologies in ways that afford agency to the digital and machinic processes over human bodily skill. Three-dimensional printed clay has also gained prominence as a resilient material well suited to the design and fabrication of artificial reef and habitat- enhancing seawall structures for coastal marine environments depleted and disrupted by human activity, climate change and pollution. Still, these projects face similar challenges when three-dimensional printing complex forms from the highly plastic and somewhat unpredictable feed material of clay. In response, this article outlines a research project that seeks to improve the translation of complex geometries into physical clay artefacts through additive three- dimensional printing processes by drawing on the notion of digital craft and giving focus to human–machine interaction as a collaborative practice. Through the case study of the 1:1 scale fabrication of a computationally generated bio-reef structure using clay as a feed material and a readily available Delta Potterbot XLS-2 ceramic printer, the research project documents how, by exploiting the human ability to intuitively handle clay and adapt, and the machine’s ability to work efficiently and with precision, humans and machines can fabricate together . With the urgent need to develop more sustainable building practices and materials, this research contributes valuable knowledge of hybrid fabrication processes towards extending the accessibility and viability of clay three-dimensional printing as a resilient material and fabrication system.

title	Microbiologically Activated Knitted Composites - Reimagining a column for the 21st century

summary	A column is an archetypal constituent of architecture which historically underwent constant reiteration in accordance with the prevalent architectural style, material culture or technical and structural possibilities. The project reimagined this architectural element through harnessing the synergies of digital design, textile logic, and contemporary biotechnology. Textile materiality and aesthetic are deeply rooted in architectural history as a soft and ephemeral antipode to rigid building materials. An investigation in historic mechanical hand-knitting techniques allowed to extract their underlying structural and geometric logic to develop a structural optimisation pipeline with a graded yarn as a base material and a geometric optimization based on local distribution of knitting patterns. Bacterially driven biocalcification was applied to transform the soft textile structure into a rigid material. Hereby an active textile microbiome was established through colonizing of the yarn with the bacterium S. pasteurii which successively precipitated calcite on microscale within the textile substrate hence ultimately influencing the global structural behaviour of the column.

summary	Augmented graphical thinking operates by integrating algorithmic, heuristic, and manufacturing processes. The Representation and Ideation Laboratory (RILAB-2018) exercise begins with the application of a parametric definition developed by the team of teachers, allowing for the construction of structural systems by the means of the combination of segmental shells and bending-active. The main objetive is the construction of a scientific model of simulation for bending-active laminar structures has brought into reality trustworthy previews for architectural envelopes through the interaction of parametrized relational variables. This way we put designers in a strategic role for the building of the pre-analysis models, allowing more preciseness at the time of picking and defining materials, shapes, spaces and technologies and thus minimizing the decisions based solely in the definition of structural typological categories, local tradition or direct experience. The results verify that the strategic integration of models of geometric physical optimization and spatial representation greatly expand the capabilities in the construction of the complex system that operates in the act of projecting architecture.

summary	Excessive use of aggregate materials and metals in construction should be balanced by increasing use of construction materials from annually renewable resources based on natural lignocellulosic fibers. Parametric design tools gave here a possibility of using an alternative newly developed biocomposite material, for realization of complex geometries. Contemporary digital fabrication tools have enabled precise manufacturing possibilities and sophisticated geometry-making to take place that helped in obtaining high structural behavior of the overall global geometry of the discussed project. This paper presents a process of realizing an experimental structure made from Natural Fiber-Reinforced Polymers (NFRP)- also referred to as biocomposites, which were synthesized from lignocellulosic flexible core reinforced by 3D-veneer layers in a closed-moulding vacuum-assisted process. The biocomposite sandwich panels parameters were developed and defined before the final properties were imbedded in the parametric model. This paper showcases the multi-disciplinarity work between architects, structural engineers and material developers. It allowed the architects to work on the material development themselves and enabled to apply a new created design philosophy by the first author, namely applying ‘Materials as a Design-Tool’. The erected biocomposite segmented shell construction allowed a 1:1 validation for the whole design process, material development and the digital fabrication processes applied. The whole development has been reached after merging an ongoing industrial research project results with academic education at the school of architecture in Stuttgart-Germany.

title	HMTM: Hygromorphic-Thermobimetal Composites as a Novel Approach to Enhance Passive Actuation of Adaptive Façades
source	Ji-Hyun Lee (Eds.) "Hello, Culture!" [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, pp. 290-300
summary	Typical adaptive facades rely on mechanical actuators that respond to the outdoor climate and regulate its effect on indoor spaces. With the emergence of ubiquitous computing, several studies have independently utilized the latent properties of programmable materials, such as the hygroscopic properties of wood and the difference in expansion coefficient of metals, to passively program material response. Motion stimuli vary for each material however, involving changes in humidity and temperature fluctuation for wood and metals respectively. This paper introduces Hygromorphic-Thermobimetal (HMTM), as a low-tech low-cost passive programmable composite. A series of physical experiments are conducted to deduce design parameters that induce specific actuation mechanisms based on the stimulation of both hygroscopic properties in wood and metal expansion through temperature variation. This allows for an extended implementation of the hygroscopic properties of wood and its actuation configurations in hot arid climates, where variation in temperature, rather than humidity, is more dominant.

summary	Situated within the art of cutting solids (stereotomy) and the evolution of machine tools; this research will investigate subtractive fabrication in relation to robotic carving of stone structures. The advancement of the industrial revolutions in the mid to late 19th century saw the rise of new building techniques and materials which were primarily based on structural steel construction. The modern aesthetic of the time further diminished the place of traditional stonework and ornamentation in modern structures within the building arts. This paper will focus on the design and fabrication of three sculptural dry-stone modular prototypes investigating interlocking self-supporting structures in stone. Examining the value of robotic technologies in the design and construction process in relation to collaborative crafting of the hand and machine. Accommodating for material tolerances which are a major factor in this research. Interrogating the value of robotic crafting with material implications and exploring the role of the artisan in machine crafted architectural components.

summary	This paper constructs a lexicon of tacit intentionalities around tools and materials in computational design and fabrication contexts through a close study of dynamic molds. Drawing on historical, theoretical, and practice-based research we develop methods for reading, teaching, and designing with intelligence in computational design contexts in concert with the tacit information provided by tools and materials.

summary	The benefits of additive manufacturing technologies for the production of customized construction elements has been well documented for several decades. Multi-material additive manufacturing (MM-AM) enhances these capacities by introducing region-specific characteristics to printed objects. Several examples of the production of multi-material assemblies, including functionally-graded materials (FGMs) exist at the architectural scale, but none are known for ceramics. Factors limiting the development and application of this production method include the cost and complexity of existing MM-AM machinery, and the lack of a suitable computational workflow for the production of MM-AM ceramics, which often relies on a continuous linear toolpath. We present a method for the MM-AM of paste-based ceramics that allows for unique material expressions with relatively simple end-effector design. By borrowing methods of co-extrusion found in other industries and incorporating a 4th axis of motion into the printing process, we demonstrate a precisely controlled MM-AM deposition strategy for paste-based ceramics. We present a computational workflow for the generation of toolpaths, and describe full-body tiles and 3D artifacts that can be produced using this method. Future process refinements include the introduction of more precise control of material gradation and refinements to material composition for increased element functionality.

summary	This paper aims to link human's emotions and cognition to the built environment to improve the user's mental health and well-being. It focuses on cyber-physical adaptive spaces that can respond to the user's physiological and psychological needs based on their biological and neurological data. Through artificial intelligence and affective computing, this paper seeks to create user-oriented spaces that can learn from occupant's behavioral patterns in real-time, reduce user's anxiety and depression, enhance environmental quality, and promote more flexible human-centered designs for people with mental/physical disabilities. To achieve its objectives, this research integrates tangible computing devices/interfaces, robotic self-adjusting structures, interactive systems of control, programmable materials, human behavior, and a sensory network. Through embedded responsiveness and material intelligence, the goal is to blur the lines between the physical, digital, and biological spheres and create cyber-physical spaces that can "feel" and be controlled by the user's mind and feelings.
