summary	The manufacture of concrete funicular shells often relies on traditional formwork construction techniques to provide a sculptured cavity for the fluid material to occupy (Bechthold, 2004). While this enables a predictable geometric outcome, the extensive use of timber and/or steel to construct these formworks account for up to 60% of the total production cost of concrete and are discarded after the casting is complete (Lloret et al. 2014). Thus, we propose an alternative method to create prefabricated modular systems out of concrete casted in customised tubular knitted membranes. These perform as a network of struts that can be affixed onto 3D printed nodes of a singular design. Altogether, these components serve as a kit-of-parts that can be transported to site and assembled together to create shell geometries.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
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.

title	Mesh Mould: Differentiation for Enhanced Performance
doi	https://doi.org/10.52842/conf.caadria.2014.139
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 139–148
summary	Mesh-Mould is a novel robotic fabrication system for complex, non-standard concrete structures. The system folds together formwork and reinforcement, the two most labour intensive aspects of concrete constructions and offers an alternative approach to the current modes of prefabrication by suggesting an in-situ fabrication process (Figure 1). The paper outlines the development of the Form-work/Reinforcing Meshes through several iterations of physical and digital tests. Initially starting from simple triangulated 3D lattices, the structures evolved to become more complex and differentiated. The incorporating of flow enhancing ducts and surface perimeters with diverse surface aperture densities facilitates an optimal concrete flow and material distribution within the mesh.

title	Flexible Formwork: A methodology for casting funicular structures
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. 345-352
summary	This paper describes a method for design and fabrication of funicular structures from discrete precast concrete components. It has a critical look over traditional casting techniques and proposes a new methodology to fabricate a flexible formwork. The design process is engaged with a thorough series of analytical models and employs digital computation techniques to test their structural efficiency. Scripting, modeling and prototyping have been integrated to investigate several case studies through which a set of criteria was developed. Digital modeling tries to keep a limited number of varied components that have certain conditions at joints and flexible in other parts. This variation helps to meet the structural criterion and the flexibility of formwork results the efficiency of fabrication.

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	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	This paper is about designing a process to create a lightweight building envelope using a shrinkfilm. The advantage of using this material for architecture is that we can simply construct the complex geometry without requiring an expensive formwork. In addition to this, this research illustrates the methodology to control the 3-dimensional form of the shrink-film by using simple 2-dimensional patterns. These patterns enable us to easily manipulate the form. In this paper, the simulation and the prototyping are conducted in both physical and computational methods.

summary	This study, which scans an architectural space with two-wheel vehicle robot technology that allows the flexible collection of three-dimensional (3D) data, may initiate the interaction between human beings and architecture in the future. It focuses on extracting building geometry and capturing human behavior in order to allow a space to communicate with human behavior. The current project extracts building geometry and human behavior data to create designs through a two-wheel robot; it was a collaborative project among the students of different majors, including mechanical engineering, human interaction, computer sciences, and architectural design. In this paper, the adaptive possibility of the RGB-Depth camera is examined in extracting building geometry.

summary	Recently more researches on tangible objects have been conducted that enhance the intuitive polygonal or surface modelling of designers in digital and physical worlds. However, a few researches have been done that augment the digital solid modelling with tangible objects. In this paper, we present the Augmented Solid Modeller (ASoM) which helps designers create more complex shapes by a combination of Boolean operations between a different type of 3D-printed tangible objects, which is different from the conventional single shape type bottom-up modelling approaches. When multiple objects intersect each other at a given position and angle, the interference or removed shape is often unexpected for designers. Also, as 3D-printed objects are used for designers only to configure and discuss the shape of final digital 3D model in existing CAAD, ASoM changes the role of 3D-printed objects from the replicas to reusable tools for other modelling opportunities. We offered ASoM to students majoring or interested in CAAD and interviewed them to get comments. Since the speed and precision of 3D-printing will achieve immediate improvement, ASoM is a pioneer in developing cutting-edge approach for designers to model both in digital and physical worlds.

summary	This project emerged from collaborative trans-disciplinary research between architecture, engineering, biology, and materials science to generate novel applications in micro-scale 3D printed ceramics. Specifically, PolyBrick H2.0 adapts internal bone-based hydraulic networks through controlled water flow from 3D printed micro-textures and surface chemistry. Engagement across disciplines produced the PolyBrick series at the Sabin Lab (Sabin, Miller, and Cassab 2014) . The series is a manifestation of novel digital fabrication techniques, bioinspired design, materials inquiry, and contemporary evolutions of building materials. A new purpose for the brick is explored that is not solely focused on the mechanical constraints necessary for built masonry structures. PolyBrick H2.0 interweaves the intricacies of living systems (beings and environments combined) to create a more responsive and interactive material system. The PolyBrick 2.0 series looks at human bone as a design model for foundational research. PolyBrick H2.0 merges the cortical bone hydraulic network with new functionalities as a water filtration and collection system for self-preservation and conservation as well as passive cooling solutions. It also pushes the ability of 3D printing techniques to the microscale. These functionalities are investigated under context for a better construction material, but its use may extend further.

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	In this paper we present an outline of a newly started project to develop a tool which connects BIM to a manufacturing technique like 3D printing. First we will look some promising manufacturing techniques. We will design a small dwelling and export it into a BIM, from which we will extract our data to generate the path the nozzle has to follow. The chosen path is constrained by the material properties, the design and speed of the nozzle. To validate the system we develop a small VR tool in which we mimic a manufacturing tool.
