summary	Through the use of algorithmic design methods and an ever growing variety of digital fabrication tools the complexity of process in the architectural discipline seems to be increasing. As this statement might apply to a variety of different areas of computational design and process management, this perceived growing complexity does not have to be viewed as unnecessary complication of design processes, if palpable and justifiable benefits occur. This paper intends to analyse and investigate the potential arising from digital tools of fabrication, specifically robots and 3D printers, and from open source platforms on exploring and managing complexity while enabling both simplicity of process and simplicity of implementation through emerging open source cultures. Building on this assumptions, this paper explores the professional possibilities generated the implementation of robotics as part of the academic curriculum. The theoretical concept of Machinecraft will be introduced and showcased on two research project, both focussing on advanced digital tools, additive manufacturing and machine engineering.

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.

title	Caress of the Gaze: A Gaze Actuated 3D Printed Body Architecture

summary	This paper describes the design process behind Caress of the Gaze, a project that represents a new approach to the design of a gaze-actuated, 3D printed body architecture—as a form of proto-architectural study—providing a framework for an interactive dynamic design. The design process engages with three main issues. Firstly, it aims to look at form or geometry as a means of controlling material behavior by exploring the tectonic properties of multi-material 3D printing technologies. Secondly, it addresses novel actuation systems by using Shape Memory Alloy (SMA) in order to achieve life-like behavior. Thirdly, it explores the possibility of engaging with interactive systems by investigating how our clothing could interact with other people as a primary interface, using vision-based eye-gaze tracking technologies. In so doing, this paper describes a radically alternative approach not only to the production of garments but also to the ways we interact with the world around us. Therefore, the paper addresses the emerging field of shape-changing 3D printed structures and interactive systems that bridge the worlds of robotics, architecture, technology, and design.

summary	The use of computational formats and digital tools includ- ing machine fabrication by indigenous people worldwide to augment traditional practices and material culture is becoming more and more commonplace. However within the practice of architecture while there are indigenous architectural practitioners utilizing digital tools, it is unclear as to whether there is motivation to implement traditional in- digenous knowledge in conjunction with these computational instru- ments and methodologies. This paper explores how the tools might be used to investigate the potential for indigenous development, cultural empowerment and innovation. It also describes a general methodology whereby capacity can be shared between academia and indigenous groups to foster new knowledge through a recently implemented in- digenous focused design research entity, SITUA. The importance and significant research potential of what we term 'domain based research' is reinforced through the exploration of emergent materials and build- ing systems located within specific tribal domains. A recent project employing 3D clay extrusion printing is used to illustrate this ap- proach.

title	Clay Robotics: Tool making and sculpting of clay with a six-axis robot
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 579-588

summary	The objective of the project is to design a reproducible clay sculpting process with an industrial robotic arm using parametric con- trol to directly translate mesh geometry from Computer Aided Design (CAD) environment into a lump of clay. This is accomplished through an algorithmic design process developed in Grasshopper using the C# programming language. The design process is enabled by our robotics modelling and simulation library which provides tools for kinematics modelling, motion planning, visual simulation and networked com- munication with the robotic system. Our process generates robot joint axis angle instructions through inverse kinematics which results into linear tool paths realised in physical space. Unlike common subtrac- tive processes such as Computer Numeric Control (CNC) milling where solid material is often pulverised during machining operations, our process employs a carving technique to remove material by dis- placement and deposition due to the soft and self-adhesive nature of the clay material. Optimisation of self-cleaning paths are implemented and integrated into the sculpting process to increase pathing efficiency and end product quality. This paper documents the process developed, the obstacles faced in motion planning of the robotic system and dis- cusses the potential for creative applications in digital fabrication us- ing advanced machines that in certain terms exceed human capability yet in others are unable to reach the quality of handmade works of art.

summary	The production of concrete structure components is often a backbreaking process due to the inconvenient and time-consuming process of producing the formwork. Depending on the geometry, this can be a very time-consuming activity. A trial will be made to solve these problems within the manufacturing process using adapted binder jetting technology. First of all, the research will deal with the behavior of concrete as well as the bond between the cement paste and the aggregate. Various additives and grain sizes will be determined to find an appropriate result. On the other hand, different spray and drop systems will be analyzed to compare the new method and the common binder jetting setup. After fabricating some geometrical shapes manually the study is going to be continued using computer-aided manufacturing.

title	Use of a Low-Cost Humanoid for Tiling as a Study in On-Site Fabrication: Techniques and Methods
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 214-223

summary	Since the time architecture and construction began embracing robotics, the pre-fab movement has grown rapidly. As the possibilities for new design and fabrication emerge from creativity and need, the application and use of new robotic technologies becomes vital. This movement has been largely focused on the deployment of industrial-type robots used in the (automobile) manufacturing industry for decades, as well as trying to apply these technologies into off-site building construction. Beyond the pre-fab (off-site) conditions, on-site fabrication offers a valuable next step to implement new construction methods and reduce human work-related injuries. The main challenge in introducing on-site robotic fabrication/construction is the difficulty in calibrating robot navigation (localization) in an unstructured and constantly changing environment. Additionally, advances in robotic technology, similar to the revolution of at-home 3D printing, shift the ownership of modes of production from large industrial entities to individuals, allowing for greater levels of design and construction customization. This paper demonstrates a low-cost humanoid robot as highly customizable technology for floor tiling. A novel end-effector design to pick up tiles was developed, along with a localization system that can be applied to a wide variety of robots.

title	Design Considerations Due to Scale Effects in 3D Concrete Printing
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 115-124
summary	The effect of scale on different parameters of the 3D printing of concrete is explored through the design and fabrication of a 3D concrete printed pavilion. This study shows a significant gap exists between what can be generated through computer aided design (CAD) and subsequent computer aided manufacturing (generally based on CNC technology). In reality, the 3D concrete printing on the one hand poses manufacturing constraints (e.g. minimum curvature radii) due to material behaviour that is not included in current CAD/CAM software. On the other hand, the process also takes advantage of material behaviour and thus allows the creation of shapes and geometries that, too, can’t be modelled and predicted by CAD/CAM software. Particularly in the 3D printing of concrete, there is not a 1:1 relation between toolpath and printed product, as is the case with CNC milling. Material deposition is dependent on system pressure, robot speed, nozzle section, layer stacking, curvature and more – all of which are scale dependent. This paper will discuss the design and manufacturing decisions based on the effects of scale on the structural design, printed and layered geometry, robot kinematics, material behaviour, assembly joints and logistical problems. Finally, by analysing a case study pavilion, it will be explore how 3D concrete printing structures can be extended and multiplied across scales and functional domains ranging from structural to architectural elements, so that we can understand how to address questions of scale in their design.

title	The Tectonic of the Hybrid Real: Data Manipulation, Oxymoron Materiality, and Human-Machine Creative Collaboration

summary	This paper describes the latest progress of the design platform Digital Impressionism (DI), created by staff and students in the Information Experience Design programme at the Royal College of Art in London. DI aims to bridge human creative thinking with machine computation, under the theoretical method/concept of oxymoron tectonic. Oxymoron tectonic describes the process under which hybrid materiality, that is the materiality created between the digital and the physical, takes form in human-machine creative interactions. The methodology intends to employ multimaterial 3D printers in combination with data manipulation (a process that gives data physical substance), pointclouds, and the influence of intangible environmental data (like sound and wind) to model physical forms by interfacing digital and physical making. In DI, modeling is a hybrid set of actions that take place at the boundary of the physical and digital. Through this interactive platform, design is experienced as a complex, hybrid process, which we call a digital tectonic; forms are constructed via a creative feedback loop of human engagement with nonhuman agents to form a creative network of sustainable and interactive design and fabrication. By developing a mutual understanding of design, machines and humans work together in the process of design and making.

title	From Bones to Bricks: Design the 3D Printed Durotaxis Chair and La Burbuja Lamp

doi	https://doi.org/10.52842/conf.acadia.2016.318
summary	Drawing inspiration from the variable density structures of bones and the self-supported cantilvers of corbelled brick arches, the Durotaxis Chair and the La Burbuja lamp explore a material-based design process by responding to the challenge of designing a 3D print, rather than 3D printing a design. As such, the fabrication method and materiality of 3D printing define the generative design constraints that inform the geometry of each. Both projects are seen as experiments in the design of 3D printed three-dimensional space packing structures that have been designed specifically for the machines by which they are manufactured. The geometry of each project has been carefully calibrated to capitalize on a selection of specific design opportunities enabled by the capabilities and constraints of additive manufacturing. The Durotaxis Chair is a half-scale prototype of a fully 3D printed multi-material rocking chair that is defined by a densely packed, variable density three-dimensional wire mesh that gradates in size, scale, density, color, and rigidity. Inspired by the variable density structure of bones, the design utilizes principal stress analysis, asymptotic stability, and ergonomics to drive the logics of the various gradient conditions. The La Burbuja Lamp is a full scale prototype for a zero-waste fully 3D printed pendant lamp. The geometric articulation of the project is defined by a cellular 3D space packing structure that is constrained to the angles of repose and back-spans required to produce un-supported 3D printing.

summary	This paper discusses our ongoing research into hierarchical volumetric modeling and the external forces which are motivating a shift from the traditional boundary representation (also known as BREP) that has thus far dominated design software toward a more flexible voxel-based representation capable of describing complex variable material distributions. We present Monolith; a volumetric modelling application which explores hybrid forms of digital representations and new design workflows that extend a designer's ability to describe the material properties of a 3d model at the mesoscopic and even microscopic scales. We discuss the inherent complexities in volumetric modelling and describe the design opportunities which heretofore were unavailable using existing techniques.

summary	This study presents preliminary results of an experiment of production and use of tactile models to explain the form of an architectural space for visually impaired people. As part of a literature review, it explores the digital manufacturing technologies such as laser cutting and 3D printing to generate representations. The review uses a case study representing a house-museum and the experiments are based on a partnership with a school for a visually impaired people. The collaborative process has contributed to learning and explanation of multi-sensory characteristics of the constructed spaces and reinforced the need for a revision of educational processes for the architectural project regarding the habit of prioritizing essentially the aesthetic and visual aspects. The universal design concept gives grounds for each action.

summary	This article describes the methods of an inclusive design project developed by FACAMP’s NIEDA , as demanded by the UNICAMP Science Museum (Brazil). The objective was to create a multi-sensorial interface that would be capable of describing the process of energy generation and distribution in a hydro-power plant. It began with a scheme based on images and a narration was built out of audible and tactile systems so that it would be comprehensible for the blind public as well, without compromising the aesthetic and informative aspects. It also reveals the challenge of combining the use of multiple technological resources, such as 3D printing and laser cutting.

doi	https://doi.org/10.52842/conf.acadia.2016.332
summary	The research presented in this paper is part of a larger, emerging body of research into large-scale 3D printing. The research attempts to develop a computational design method specifically for large-scale 3D printing of architecture. Influenced by the concept of Digital Materials, this research is situated within a critical discussion of what fundamentally constitutes a digital object and process. This requires a holistic understanding, taking into account both computational design and fabrication. The intrinsic constraints of the fabrication process are used as opportunities and generative drivers in the design process. The paper argues that a design method specifically for 3D printing should revolve around the question of how to organize toolpaths for the continuous addition or layering of material. Two case-study projects advance discrete methods as efficient ways to compute a continuous printing process. In contrast to continuous models, discrete models allow users to serialize problems and errors in toolpaths. This allows a local optimization of the structure, avoiding the use of global, computationally expensive, problem-solving algorithms. Both projects make use of a voxel-based approach, where a design is generated directly from the combination of thousands of serialized toolpath fragments. The understanding that serially repeated elements can be assembled into highly complex and heterogeneous structures has implications stretching beyond 3D printing. This combinatorial approach for example also becomes highly valuable for construction systems based on modularity and prefabrication.

summary	Computational design was developed to solve complex problems in architecture and to enable the establishment of systems with complex properties in a holistic manner. With the enhanced capabilities of computational design, there are possibilities to develop integrated approaches to adapt to multi-faceted design problems. Swarm-based multi-agent systems (MAS) are already used as generative bottom-up methods in various design operations, including form-finding and optimization. This study presents a systematic approach, in which multi-agent systems are informed by the environmental performance assessment data where the output is directly linked to the 3D printing process. The intent is to increase efficiency within the design and prototyping process by integrating performance and fabrication into the early stages of the design process. The proposed method has been applied as a case study to a diverse group of students and professionals. The results have proven that applying this systematic approach enabled the designers to achieve highly sophisticated, formal and organizational outputs, with enhanced spatial and geometric qualities.

title	Highly Informed Robotic 3D Printed Polygon Mesh: A Nobel Strategy of 3D Spatial Printing

summary	Though robotic 3D printing technology is currently undergoing rapid development, most of the research and experiments are still based on a bottom up layering process. This paper addresses long term research into a robotic 3D printed polygon mesh whose struts are directly built up and joined together as rapidly generated physical wireframes. This paper presents a novel “multi-threaded” robotic extruder, as well as a technical strategy to create a “printable” polygon mesh that is collision-free during robotic operation. Compared to standard 3D printing, architectural applications demand much larger dimensions at human scale, geometrically lower resolution and faster production speed. Taking these features into consideration, 3D printed frameworks have huge potential in the building industry by combining robot arm technology together with FDM 3D printing technology. Currently, this methodology of rapid prototyping could potentially be applied on pre-fabricated building components, especially ones with uniform parabolic features. Owing to the mechanical features of the robot arm, the most crucial challenge of this research is the consistency of non-stop automated control. Here, an algorithm is employed not only to predict and solve problems, but also to optimize for a highly efficient construction process in coordination of the robotic 3D printing system. Since every stroke of the wireframe contains many parameters and calculations in order to reflect its native organization and structure, this robotic 3D printing process requires processing an intensive amount of data in the back stage.

summary	Computational design and digital fabrication have expanded the use of digital manufacturing machineries for the realization of architecture, yet they have their own limitations of material use. These limitations caused some materials like cement, plaster and clay become marginal in this new digital context, despite their vast use in the building industry. In this context, this paper will present a research, focusing on the use of concrete through the development of a custom-designed device, which is an adjustable digital mould. This digital mould has been designed specifically for a project called Procrystalline Wall and has been 'adapted' to the conditions of its agenda in terms of size, shape, typology, and even technical matters. However, this adaptability means that the device is not aimed to work for any other project and remain exclusive to this particular design only. This paper will further discuss the validity and obstacles of the presented method in a more global context.
