summary	Bending-active structures have drawn considerable attention in the past decades of research and practice. However, most existing bending active structures are made of homogeneous materials with constant bending properties, making it difficult to achieve complex design intentions. This paper presents a novel hybrid material design strategy that enables the realization of curved active structures with complex geometries. This hybrid material consists of birch plywood and 3D printed PETG. The bending behavior of the hybrid material can be adjusted by changing the density of the 3D-printed part.

title	Robotic 3D printed lunar bionic architecture based on lunar regolith selective laser sintering technology
doi	https://doi.org/https://doi.org/10.1007/s44223-022-00014-9
source	Architectural Intelligence Journal
summary	The lunar base is not only an experimental station for extraterrestrial space exploration but also a dwelling for humans performing this exploration. Building a lunar base presents numerous obstacles and requires environmental perception, feedback design, and construction methods. An integrated fabrication process that incorporates design, 3D printing workflow, and construction details to build a bionic, reconfigurable and high-performance lunar base prototype is presented in this paper. The research comprises the study of the lunar regolith 3D printing mechanism, the real-time control of powder laying and compaction procedure, and the development of a 3D printing tool end system. In this paper, many scientific questions regarding in situ fabrication on the lunar surface are raised and addressed with the proposal of a progressive optimization design method, the molding principle, and gradation strategy of lunar soil-polyaryletherketone (PAEK) hybrid powder, and the principle of dual-light field 3D laser printing. The feasibility of the technical strategy proposed in this paper is verified by the presented empirical samples.

title	Shell Structure of Bamboo Composite
source	Herrera, PC, Dreifuss-Serrano, C, Gómez, P, Arris-Calderon, LF, Critical Appropriations - Proceedings of the XXVI Conference of the Iberoamerican Society of Digital Graphics (SIGraDi 2022), Universidad Peruana de Ciencias Aplicadas, Lima, 7-11 November 2022 , pp. 445–454
summary	This research is aimed at proposing a lightweight shell structure made from a bamboo composite. The research explores the addition of glass fiber to bamboo veneer for adhesion to produce a bamboo composite. Adding glass fiber improves the material’s elasticity and ductility and strengthens the bond between units of laminated bamboo veneer. Moreover, we utilized a simulation tool to analyze the structural performance and compare the shell structure’s mechanical differences before and after adding the glass fiber. In terms of fabrication, this paper presents a computational workflow for mesh segmentation and unrolling as well as a design for unique snap- fit joints for the connection between mesh strips. Finally, this paper outlines the fabrication of one part of the overall form as a demonstration case to verify the proposed method.

title	Toward a generative AI-augmented design era
doi	https://doi.org/https://doi.org/10.1007/s44223-023-00038-9
source	Architectural Intelligence Journal
summary	With the rapid development of Artificial Intelligence (AI), the relationship between humans and machines has become a significant concern. One view suggests that AI will possess subjectivity: Matias del Campo emphasises that, unlike traditional tools that teach machines how to perform, artificial intelligence teaches machines how to learn (Campo, 2022). According to him, AI has the capability and awareness to recognise the world; Neil Leach et al. argue that AI will replace the majority of architects, resulting in widespread unemployment (Leach, 2021). Other opinions hold that AI is unconscious, incapable of thought, and identical to tools such as cellular automata machines, parameterisation, etc. According to Mario Carpo, the data-driven AI employs iterative optimisation to solve problems, which must be quantifiable and amenable to optimisation. Therefore, AI’s role as a tool is limited to measurable phenomena and factors (Carpo, 2023).

title	Digital Design and Fabrication of a 3D Concrete Printed Funicular Spatial Structure
doi	https://doi.org/10.52842/conf.caadria.2022.2.071
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 71-80
summary	In recent years, additive manufacturing (AM) and 3D concrete printing technologies have been increasingly used in the field of construction engineering. Several 3D concrete printing bridges were built with post-tensioning technology. However, the current post-tensioned 3D concrete printing projects are mostly in a single direction of force. There are fewer cases of concrete printing funicular spatial structures, and most funicular spatial structures are currently manufactured by casting-in-place in formwork. This paper presents a case of manufacturing spatial 3D concrete printed structure using post-tensioned technology with multiple force direction. The design of the non-parallel printing path, the joints between single units, and the post-tensioned steel cable system in the design and research process are discussed. A funicular spatial structure is built, and a method of manufacturing 3DCP funicular spatial structure is proposed.

title	In-Situ Robotic Fabrication of Spatial Glulam Structures
doi	https://doi.org/10.52842/conf.caadria.2022.2.041
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 41-50
summary	While current approaches in timber construction stress the advantages of off-site prefabrication, glued laminated timber(glulam) structures is limited to the constraints of standardized, prefabricated mostly linear elements, which also lends itself only to building typologies that offer an increased level of standardization and regularity. The design freedom of timber structures is incomparable to that of reinforced concrete structures, which mostly gains from the in-situ fabrication process. An in-situ robotic timber fabrication platform allows the on-site construction of glulam structures with highly differentiated networks of beams composed of robotically assembled discrete linear elements. Based on the possibilities of such mobile robotic fabrication process, this paper explores novel architectural typologies of spatial glulam structures. The research is conducted from several aspects including joint tectonics, design method, and robotic fabrication process. A large-scale pavilion is designed and fabricated to verify the feasibility of the proposed system. This research could provide a novel mode of in-situ robotic timber fabrication and corresponding glulam structure system for timber construction.

title	Extrusion-Based 3d Printing for Recyclable Gypsum
doi	https://doi.org/10.52842/conf.caadria.2022.2.273
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 273-282
summary	Gypsum is one of the most commonly used construction materials in cladding and non-load-bearing decoration. Recently, 3D printing technology has been involved in creating complex geometry. The particle-based method is the principal approach in 3D gypsum printing. However, the complex device and limited printable range limit the massive production of large-scale building components. This paper proposed a novel extrusion-based gypsum printing method and corresponding robotic fabrication workflow. First, several experiments are conducted to analyze the effect of different admixtures (retarder, activation agent, and accelerator) on the material setting properties. Second, a set-on-demand gypsum-based material is proposed by actively controlling multiple admixtures. Then, a process parameter-based robotic fabrication workflow is proposed, and a set of extrusion- based 3D gypsum printing equipment is built. center864108000A curved gypsum panel sample is printed as experimental verification. By comparing to the particle-based method, The test sample shows that the extrusion-based method can effectively improve the production efficiency and reduce the production cost. Therefore, the proposed method gives a relatively efficient and cost-effective way to produce recyclable gypsum material massively.

title	Fabrication of Reinforced 3D Concrete Printing Formwork
doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_44
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
summary	In recent years, the emerging 3D printing concrete technology has been proved to be an effective and intelligent strategy compared with conventional casting concrete construction. Due to the principle of additive manufacturing strategy, this concrete extrusion technique creates great opportunities for designing freeform geometries for surface decoration since this material has a promising performance of high compressive strength, low deformation, and excellent durability. However, the structure behavior is usually questioned, defined by the thickness and printing path. At the same time, the experiments for using 3D printing elements for structural and functional parts are still insufficient. Little investigation has been made into developing reinforcement strategies compatible with 3D printing concrete. In fact, conventional formwork and easy-to-install reinforcement support structures have various advantages in terms of labor costs but can hardly be reused. Thus, using 3D concrete printing as formwork for projects in different scales is an effective solution in the mass customized prefabrication era. Considering large-scale projects, the demand to provide concrete formwork with a proper reinforcement strategy for better toughness, flexibility, and strength is necessary. In this paper, we proposed different off-site reinforced 3D printing concrete strategies and evaluated them from time and material cost, deviation, and accessibility of fabrication.

summary	Architectural Intelligence, guided by scientific design thinking, focuses on the three future scenarios of smart habitat, virtual habitat, and space habitat. Utilizing evidence-based architectural research methods, Architectural Intelligence reconstructs the architectural knowledge system and creates an international academic platform of multi-disciplines, establishing a new paradigm for sustainable development. In the first place, it is necessary to define architectural intelligence. In her book Architectural Intelligence: How Designers and Architects Created the Digital Landscape, Molly Wright Steenson argued that intelligence is rather expressed in design processes and tools, computer programs, interfaces, and digital environments and it includes all forms of intelligence involved with the built environment.

title	DfD-based Design, Assembly, High-Accuracy Real-time Monitoring and Levelling Calibration for Large-scale Prefabricate Structure with Multiple Measuring Systems
doi	https://doi.org/10.52842/conf.caadria.2022.2.517
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 517-526
summary	This article introduces a novel monitoring method for the construction of high-precision prefabricated structures based on multiple sensors and measurement technologies. The proposed method introduces the optical motion capture system and combines it with traditional construction measurement technology to achieve real-time dynamic monitoring of more than hundreds of points within a large construction area more than 1810m. Tolerance fitting algorithms and the correction methods are developed and testified to provide a global tolerance with ±1mm. Meanwhile a real-time visualization interface is developed to provide the feedback and analysis of the tolerance for each structure components. As demonstrator, such monitoring system is applied in the real construction of a DfD (Design for Disassembly)-based prefabricated steel structure in the "Water Cube‚ (Chinese National Aquatics Centre) in Beijing. With the demand to control the flatness tolerance within 6mm (within a 2550m area), a large area monitoring system was applied in the project and finally reduced the construction time within 20 days.

title	Levelling Calibration and Intelligent Real-Time Monitoring of the Assembly Process of a DfD-Based Prefabricated Structure Using a Motion Capture System

summary	Conventional measuring techniques and equipment such as the level and total-station are commonly used in on-site construction to measure the position of building elements. However, a motion capture system can measure the dynamic 3D movements of markers attached to any target structure with high accuracy and high sampling rate. Considering the characteristics of prefabricated structures that is composed by lot of discrete building elements, advanced requirements for the on-site assembly monitoring is required. This paper introduces an innovative real-time monitoring technique for the DfD-based (Design for Disassembly) structure with the application of motion capture system and other hardware in an IoT-based BIM system. The design and construction method of the structure system, on-site setup of monitoring system and hardware, data acquisition and analysis method, calibration algorithm as well as the BIM system are further illustrated in the paper. The proposed method is finally applied in a real building project that is composed by thousand discrete building elements and covers a large area of 5025 m. As demonstrator, such monitoring system is applied in the real construction of a DfD-based prefabricated steel structure in the “Water Cube” (Chinese National Aquatics Centre) in Beijing. The building process is successfully recorded and displayed on-site with the digital twin model in the BIM system. The construction states of the building elements are gathered with different kind of IoT techniques such as the RfID chips and QR-Codes. With the demand to control the flatness tolerance within 6 mm (within a 2550 m area), a large area monitoring system was applied in the project and finally reduced the construction time within 20 days. The final tolerance is verified and further discussed2.

summary	This paper proposes a glass 3D printing system that can be used at room temperature. The system employs high-frequency electromagnetic induction heaters and stone-ground carbon tubes to heat glass raw materials. In this study, a digital control system was fully utilised to control the extrusion of borosilicate glass materials. Through a calculated design and communication between a six-axis robot arm and an external computer, the robot’s printing path and speed and the feeding state of the glass printing machine can be automatically controlled for different geometric shapes and velocities. This study examines digital manufacturing processes and material properties to investigate the novel glass printing of textures and free-form surface modelling.

source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
summary	This article presents the design process for generating a shell-like structure from an activated bent auxetic surface through an inductive process based on applying deep learning algorithms to predict a numeric value of geometrical features. The process developed under the Material Intelligence Workflow applied to the development of (1) a computational simulation of the mechanical and physical behaviour of an activated auxetic surface, (2) the generation of a geometrical dataset composed of six geometric features with 3,000 values each, (3) the construction and training of a regression Deep Neuronal Network (DNN) model, (4) the prediction of the geometric feature of the auxetic surface's pattern distance, and (5) the reconstruction of a new shell based on the predicted value. This process consistently reduces the computational power and simulation time to produce digital prototypes by integrating AI-based algorithms into material computation design processes.

source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 243-252
summary	This paper introduces and investigates NiChrome wire sintering, a novel fabrication technique in the field of additive manufacturing. With a combination of differentiated material states and material properties, this research generates forms with different sintering strategies through computation and fabrication systems. Rather than creating objects through selectively depositing melted material in a predetermined path, layer-by-layer, this rapid prototyping methodology generates 2D or 3D spatial wireframes by weaving NiChrome wire and sintering thermoplastic polyurethane (TPU) onto it by utilizing the instantaneous high temperature of NiChrome wire after electrification. A series of experiments is presented utilizing a proportional integral derivative (PID) temperature control system in cooperation with thermal camera equipment to ensure consistent results under the same conditions. In addition, the project focuses not only on developing NiChrome wire sintering systems but also on the applicabilities of this technique by fabricating wireframe surfaces under different situations.
