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	This research describes the outcome of the Angewandte Architecture Challenge 2013 “Robotic Infiltrations” experimental workshop in Digital Design and Fabrication Strategies. The workshop is a collaboration between the University of Innsbruck’s REX\|LAB and the Institute of Architecture at the University of Applied Arts Vienna, and represents a continuation of research that explores the potential of additive digital production through the use of robotically controlled placement of phase-change polymers in the production of full scale structures.

title	Generico - A case study on performance-based design
source	SIGraDi 2014 [Proceedings of the 18th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-9974-99-655-7] Uruguay- Montevideo 12,13,14 November 2014, pp. 126-129
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.

title	Self-Serveying Multi-Robot System for Remote Deposition Modelling
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 233–240
doi	https://doi.org/10.52842/conf.ecaade.2022.1.233
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.
