title	Mathematics and computation: Using visual programming to develop didactic materials in a learning environment
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 581-588.
summary	We analyse the problem of creating didactic material for teaching and evaluating mathematics in the first year of a School of Architecture. By using visual programming, science professor used codes (formulae) to represent in a software their proposals, instead of drawing them themselves. Through this experience we create a database of codes with computational solutions that allows faculty to modify, reuse, visualise and print in the same platform that she students will use while developing their designs. In this way we aim to maximise the link between mathematics and design as fundamental base for the control of complex shapes.

title	Super-details: Integrated patterns from 3D printing processes to performance-based design
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 463.
summary	Performance-based architecture has predominately been influenced by computational advances in simulating complex organizations. The advent of 3D printing, however, has introduced a new approach to generate complex forms, which is redirecting focus from shape-centric design to material design, namely, innovative structures and properties generated by the process itself. This article investigated the multiscale approach potential to design using extrusion-based 3D printing techniques that offer novel geometric organizations that conform to desired performance. It was found that 3D printed toolpaths adapted to extrusion-based systems render an anisotropic behavior to the architectural object that is best optimized by designing tessellated surfaces as the primary structural shape from which small-scale periodic surfaces can be embedded within a larger geometric system.

title	3D printing as support for arts education for the visually impaired
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 564-568.
summary	This article discusses some methodologies in art education in schools and educational activities in museums. It focuses on accessibility and in the visually impaired rights to access and improve the experiences and repertoire in artistic languages, recognizing the use of new technologies in the field of digital manufacturing as valuable resources for the production of teaching materials with the use of cheaper and accessible technology, which expands the access to cultural institutions and education. Considering that most of the museums art works are not to be touched, 3D printing reproductions in durable low cost plastic present as an alternative for tactile experience. In addition, the photogrammetric 3D scanning process and digital editing allow for the creation of isolated parts and materials originated from the art piece, broadening the pedagogical possibilities of art educators. The production of didactic material for arts teaching, with the use of 3D printed copies (edited or not) originated from 3D scans, may help revealing a more subtle and sophisticated aspect of artistic narrative to the public and the visually impaired.

summary	Modular Light Cloud is an installation that is conceived to explore the boundaries of architecture and art. Its interactivity is a metaphor of mutual influences that derive from activities performed in space - associated with motion, sound and light.It is an experimental project focused on the integration of architectural elements, structure, information technology, performing arts, electronics and digital fabrication in architectural education.The project was completed in a two-week student workshop in collaboration with a contemporary dance artist. The students were taught the basics of parametric design, programming of electronic components and digital fabrication during tutorial classes. The making process combined three stages of development: design, construction and programming of interaction.The final form consists of two irregular spatial trusses made of aluminum profiles connected with 3d printed nodes. The profiles are equipped with LED strips and electronic components: light sensors, sound and communication between them. These systems control the intensity of light emitted by the diodes based on the inputs.The result is a working prototype presented as interactive installation featuring contemporary dance artist. It was displayed at art festivals and other events.

title	Confluence of Parametric Design and Digital Fabrication Restructuring Manufacturing Industries
doi	https://doi.org/10.52842/conf.caadria.2015.013
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 13-22
summary	The positive consumer reception of 3D printed products suggests that the coupling of digital fabrication technology and parametric design methodologies presents opportunities and challenges to traditional modes of industrial manufacturing. This paper outlines the manner in which parametrically defined constraints of components within design hysteresis can be implemented to maintain conformation to real world constraints. The study challenged ten architectural designers to develop parametric definitions using conventional CAD software and visual programming languages to describe the geometric logic of a simple pendant lamp while permitting some consumer defined shape parameters. The assessment of submitted design descriptions suggests that defining such a system parametrically for manufacturing requires the development of an approach that is capable of not only intelligently managing interdisciplinary dependencies but also evaluating performance factors within implicit design space. During the next phase of this research, focus will be on the application of the proposed constrained design hysteresis methodology in collaboration with a major manufacturing industry partner to further develop and explore its potential in real world implementation. If proven effective, it can be expected that adoption of the combination of parametric design tools and digital fabrication among major manufacturing industries will be pervasive in the coming years.

title	Anisoptera; Anisopteran Deformation and the Latent Geometric Patterns of Wood Envelopes
doi	https://doi.org/10.52842/conf.acadia.2015.047
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 47-56
summary	Advancements in technologies provide Architects, today, with the means to expose new expressive forms using traditional materials. It is therefore possible to design dynamic actuating systems, where several different expressions, or differentiations inherent in the same material, are able to modify its topology and enhance its properties. Wood, traditionally used in construction, is given static expression during its life cycle, where an alignment, or assembly detail, helps retain its original shape. This research outlines the integration of specific and individual anatomical information of wood during the design process. It aids in utilizing the analyzed biological variability and natural irregularities of wood within a material-based architecture, in view of developing a lightweight, and light-filtering dynamic skin. Additionally, the research helps to explore an understanding of the differentiated material composition of wood as its major capacity, rather than its deficiency. Moreover, it analyzes form, material, and structure, as complex interrelations that are embedded in, and explored through an integral design process that seeks to employ typically disregarded, highly differentiated flat materials, in view of enhancing their latent dimensional deformation potential. The main focus of this research is to explore that latent geometric deformation of emerging patterns based on an array of heterogeneous wood veneers in relation to their Hygroscopic and Anisotropic properties. These properties are expressed through a set of flat skins and Mobius arrangements, articulating complex geometric ranges that reveal additional properties, such as bendability and flexibility.

title	The Use of Digital Fabrication as a Sketching Tool in the Architectural Design Process - A Case Study
doi	https://doi.org/10.52842/conf.ecaade.2015.2.319
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 319-324
summary	Computer-aided manufacturing (CAM) technologies including computer numerically controlled (CNC) milling, laser cutting and 3D printing are becoming cheaper and globally more accessible. Accordingly, many design professionals, academics and students have been able to experience the benefits and challenges of using digital fabrication in their designs. The use of digital fabrication in the education of architecture students has become normal in many schools of architecture, and there is a growing demand for computer-aided manufacturing (CAM) logic and fabrication knowledge in student learning. Clearly, architecture students are acquiring material base-thinking, time management, production methods and various software skills through this digital fabrication. However, it appears to be the case that architecture students use digital fabrication mainly in the final stage of their design or in their finishing work. In this study, computer-aided manufacturing (CAM) technologies have been used as a sketch tool rather than simply for fabricating a final product in the architectural design process and the advantages of this educational practice are demonstrated.

title	Digital-Material Feedback in Architectural Design
doi	https://doi.org/10.52842/conf.caadria.2015.631
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 631-640
summary	This paper studies the architectural potential of the implementation of material feedback using computer vision before and during an automated fabrication process. The combination of an industrial robot and a 3D camera is used expand the typical one-way design and fabrication process (from a digital design to a physical output), to a feedback loop, where specific material information becomes the main trigger of design decisions and fabrication processes. Several projects developed by the authors and tested during a robotic workshop aim to unveil different aspects of material feedback in architectural design, opening a discussion for the benefit and challenges of this new approach to design and fabrication.

title	Extending Processing to CAD applications

summary	The Processing language was created to teach programming to the design, architecture, and electronic arts communities. Despite its success, Processing has limited applicability in the architectural realm, as no CAD (Computer-Aided Design) or BIM (Building Information Modeling) application supports Processing. As a result, architects that have learnt Processing are unable to use the language in the context of modern, script-based, architectural work. This work joins Processing with the world of CAD or BIM applications, creating a solution that allows architects to prototype new designs using Processing and generate results in a CAD or BIM application. To achieve this, we developed an implementation of Processing for the Rosetta programming environment, allowing Processing scripts to generate 2D and 3D models in a variety of CAD or BIM applications, such as AutoCAD, Rhinoceros3D, SketchUp, and Revit.

title	Protocol of Error: The design and construction of a bending-active gridshell from natural bamboo
doi	https://doi.org/10.52842/conf.caadria.2016.415
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. 415-424
summary	This paper advocates alternative methods to overcome the impossibility of realising ‘perfect’ digital designs. It discusses Hong Kong’s 2015 ‘ZCB Bamboo Pavilion’ as a methodological case study for the design and construction of architecture from unprocessed natu- ral bamboo. The paper critically evaluates protocols set up to deal with errors resulting from precise digital design systems merging with inconsistent natural resources and onsite craftsmanship. The paper starts with the geometric and tectonic description of the project, illus- trating a complex and restrictive construction context. Bamboo’s unique growth pattern, structural build-up and suitability as a bending- active material are discussed and Cantonese bamboo scaffolding craftsmanship is addressed as a starting point for the project. The pa- per covers protocols, construction drawings and assembly methods developed to allow for the incorporation and of large building toler- ances and dimensional variation of bamboo. The final as-built 3d scanned structure is compared with the original digital model. The pa- per concludes by discussing the necessity of computational architec- tural design to proactively operate within a field of real-world inde- terminacy, to focus on the development of protocols that deal with imperfections, and to redirect design from the virtual world towards the latent opportunities of the physical.

summary	Recent developments in Additive Manufacturing are creating possibilities to make not only rapid prototypes, but directly manufactured customised components. This paper investigates the potential for combining standard building materials with customised nodes that are individually optimised in response to local load conditions in non-standard, irregular, or doubly curved frame structures. This research iteration uses as a vehicle for investigation the SmartNodes Pavilion, a temporary structure with 3D printed nodes built for the 2015 Bi-City Biennale of Urbanism/Architecture in Hong Kong. The pavilion is the most recent staged output of the SmartNodes Project. It builds on the findings in earlier iterations by introducing topologically constrained node forms that marry the principals of the evolved optimised node shape with topological constraints imposed to meet the printing challenges. The 4m high canopy scale prototype structure in this early design research iteration represents the node forms using plastic Fused Deposition Modelling (FDM).

title	Assisted construction of non-standard wooden walls and envelope structures by parametric modeling
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 328.
summary	We introduce a parametric modeling method in the field of computer-aided architectural conception, which aims to produce non-standard wooden walls and envelopes with CNC machinery. This method explores the application of polygonal cellular structures (as patterns) on facade and envelope interventions for new and old projects. We innovate by bringing the 3D production environment complexity into the conception model to improve the production of manifold woodworking items by CNC (Computer Numerical Control) 3D fabrication. A recent experimentation, tests the entire workflow from parametric modeling to production of two full-scale prototypes. The results prove the range of inputs offered by the method to be functional, though it needs various improvements in order to optimize parametric modeling and digital fabrication procedures. Future research will focus on treating a wider range of joints via parametric modeling and deal with joint creation regardless wall deformation to expand the morphological approach of non-standard wooden walls design.

summary	With an exponential increase in the possibilities of computation and computer-controlled fabrication, high density information is becoming a reality in digital design and architecture. However, construction methods and industrial fabrication processes have not yet been reshaped to accommodate the recent changes in those disciplines. Although it is possible to build up complex simulations with millions of particles, the simulation is often disconnected from the actual fabrication process. Our research proposes a bridge between both stages, where one drives the other, producing a smooth transition from design to production. A particle in the digital domain becomes a drop of material in the construction method.The architect's medium of expression has become much more than a representational tool in the last century, and more recently it has evolved even beyond a series of rules to drive from design to production. The design system is the instruction itself; embedding structure, material and tectonics and gets delivered to the very end of the construction chain, where it gets materialised. The research showcased in this paper investigates tectonic systems associated with large scale 3D printing and additive manufacturing methods, inheriting both material properties and fabrication constraints at all stages from design to production. Computational models and custom design software packages are designed and developed as strategies to organise material in space in response to specific structural and logistical input.Although the research has developed a wide spectrum of 3D printing methods, this paper focuses only on two of the most recent projects, where different material and computational logics were investigated. The first, titled Filamentrics, intends to develop free-form space frames, overcoming their homogeneity by introducing robotic plastic extrusion. Through the use of custom made extruders a vast range of high resolution prototypes were developed, evolving the design process towards the fabrication of precise structures that can be materialised using additive manufacturing but without the use of a layered 3D printing method. Instead, material limitations were studied and embedded in custom algorithms that allow depositing material in the air for internal connectivity. The final result is a 3x2x2.5m structure that demonstrates the viability of this construction method for being implemented in more industrial scenarios.While Filamentrics is reshaping the way we could design and build light weight structures, the second project Microstrata aims to establish new construction methods for compression based materials. A layering 3D printing method combines both the deposition of the binder and the distribution of an interconnected network of capillaries. These capillaries are organised following structural principles, configuring a series of channels which are left empty within the mass. In a second stage aluminium is cast in this hollow space to build a continuous tension reinforcement.

summary	This paper describes methods, processes and the outcome of the reconstruction in the medieval wooden settlement complex in Pultusk, Poland. It is the result of the interdisciplinary cooperation between architects from Warsaw University of Technology and archaeologists from Regional Museum of Pultusk. They have undertaken the research issues of information exchange and knowledge-building processes in the digital environment. Main issues were related to the methods of computer reconstruction in architectural and urban scale, which enable alternative narrative threads. To achieve this, parametric techniques were adopted and the 'Pultusk Recontructor' application was developed in Grasshopper. The interaction between architects and archaeologists over hypotheses and alternatives was supported in urban scale by 'Rapid Reconstruction Modular Model'. This 3D printed urban model, consist of segments which can be simultaneously exchanged. It became not only a substrate for scientific debate, but also may serve an education role for the permanent Museum exhibition.

title	Informed Design to Robotic Production Systems - Developing Robotic 3D Printing System for Informed Material Deposition
doi	https://doi.org/10.52842/conf.ecaade.2015.2.287
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 287-296
summary	This paper discusses the development of an informed Design-to-Robotic-Production (D2RP) system for additive manufacturing to achieve performative porosity in architecture at various scales. An extended series of experiments on materiality, fabrication and robotics were designed and carried out resulting in the production of a one-to-one scale prototype. In this context, design materiality has been approached from both digital and physical perspectives. At digital materiality level, a customized computational design framework is implemented for form finding of compression only structures combined with a material distribution optimization method. Moreover, the chained connection between parametric design model and robotic production setup has led to a systematic study of certain aspects of physicality that cannot be fully simulated in the digital medium, which then establish a feedback loop for underrating material behaviors and properties. As a result, the D2RP system proposes an alternative method of robotic material deposition to create an informed material architecture.

title	Poisson's Ratio Material Distributions

summary	The Poisson’s ratio of materials describes the ratio of the transverse to axial strain. While most materials exhibit non-negative Poisson ratio, here we focus on the topological properties of negative ratio materials also known as auxetic constructs. Digital modelling and physical fabrication are employed to generate and test experimental auxetic configurations. The first set of studies employ 2D space-filling tessellations integrating both negative and positive Poisson ratio cells. The tessellations are designed through binary state transitions and gradual morphing transitions. A second set of studies explores the topological optimization of a single negative Poisson cell configuration following the logic that a cell constitutes the building block of auxetic materials. The third set of studies focuses on the translation of heterogeneous Poisson ratio 2D tessellations into 3D constructs. Here, two methods of fabrication are explored: lamination method and cellular grading. The precision of the cellular grading method renders it particularly suitable for multi-material 3D printing fabrication which is theoretically studied and proposed. Space-filling heterogeneous tessellation studies are applied to architectural and product design proposals. These proposals exhibit properties that could serve to design and develop further research on real-world applications.

title	A new meaning to the physical model: 3D printing and architectural design teaching
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 1 - ISBN: 978-85-8039-135-0] Florianópolis, SC, Brasil 23-27 November 2015, pp. 350-354.
summary	This article aims to produce reflections on two main aspects of the use of so-called 3D printing to produce physical models in architectural design processes: 1. preparation of files, preparation of students; 2. printed physical models as part of the design process. In addition to brief literature review of the key concepts involved, the article relies on results of research conducted by Nomads.usp Center of Interactive Living Studies (www.nomads.usp.br), and activities with students of the mandatory undergraduate course “Project 3: architecture, city, landscape,” both of the Institute of Architecture and Urbanism, University of Sao Paulo, IAU-USP (www.iau.usp.br), Brazil.

summary	Digital fabrication technologies are changing rapidly the way we design, as any other tool would affect the way we produce space. Multi layered 3D printing is already allowing architects, designers and engineers to experiment with new design processes and new ways of production. At the same time, little research has being done in the way gradient transparency (through multiple layered surfaces) can affect the design process through computation; a field that deserves further investigation. The focus of this paper is to explore bio-inspired material finding design processes while combining biology, architecture and material science. We explore performance driven design possibilities through a study of marine animals -and specifically cephalopods- where opacity between skin layers is controlled through color pigments - while black pigments are called melanophores - which is often used as a type of camouflage. We propose a computation model that follows the logic of gradient transparency through pigments to fit complex “host surfaces”. We define a “host” surface as a basic geometry on which the pigments are computed. This study provides the methodology for the design of biomimetic surfaces with gradient transparency, using controlled and computated sub geometries analogous to the melanophores pigments. We finally propose Pigment Skin, a computational design model as an example to materialize this study.

title	The One Day House - Intelligent Systems for Adaptive Buildings
doi	https://doi.org/10.52842/conf.ecaade.2015.2.643
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 643-650
summary	As the global population continues to climb and environmental conditions become further unpredictable, the creation of a more robust, intelligent, adaptable yet affordable housing system will become an evermore-significant issue. Existing housing typologies find themselves lagging behind other industries such as aerospace and even automotive, lacking advanced fabrication infrastructures as well as embedded intelligent technologies that could allow for: Global interconnectivity and or manipulation, automatic software/hardware updating and physical/computational adaptability. The use of advanced tools for manufacturing resembling industrial robotics, 3D printing and as well as intelligent fabrication systems currently remains nearly non-existent. Constructed using outdated design methodologies, materials and construction techniques, the current dwelling functions merely as an enclosure for life rather then an integrated system for information, comfort and commerce. This paper questions the current typology of “house” through the rethinking of not only form and material, but by reimagining the dwelling as a whole. Rather then observing the dwelling as a static form for infrastructural permanence, this paper redefines the home as a globalized commodity, which is both physically and technologically connected and adaptable.
