Parametric reciprocal structures: workshop of design and fabrication

[Excerpt] Foreword: One of the central challenges that needs to be maintained throughout new structural and constructional design pedagogy is how to impart knowledge about structural and constructive concepts in a manner that enhances the capacity to understand and apply them in design. Promoted under the auspices of the International Conference on Structures and Architecture — ICSA2016, the workshop “Parametric Reciprocal Structure: workshop of design and fabrication” had it genesis in proposals developed by students of the course of Special Structures of the Master in Architecture of the School of Architecture of the University of Minho (EAUM). The solutions designed by the students focused on the design of a reciprocal structure to be built at the Design Institute of Guimarães (former Tanning Factory of Ramada). The reciprocal structures workshop was organized as part of the special structures course. The workshop involved students and staff to implement constructive solutions, in the manufacturing and in the assembling of the structure. The initiative aimed to explore architectural and structural design concepts, embracing the research of: methods and processes of designing thinking; simulation and processing tools; and manufacturing concepts and materials. The computational model Reciprocalizer, developed by Prof. Dario Parigi from the University of Aalborg, was used for the morphological design exploration. This model allows the generation of three-dimensional reciprocal grids, characterized by a high degree of freedom and formal experimentation. The proposed combination of creative aspects in the conception and construction of structures, advanced technologies and complex architectural and structural applications represents a valuable learning experience of collaborative work.

BioTILES: a sustainable interior wall panel

The present project proposes the use of materials of natural origin in additive manufacturing, with a view to producing new decorative wall tiles. The historical evolution of the Vimaranense house, tells us a narrative that even today is kept intact by the preservation of its memory. It is common to see slate tiles in the city of Guimarães for gable linings, or additions to the roofs of buildings, such as chimneys, skylights, and rooflights. The ‚soletos‘ or fish scales, are tiles of small dimensions and distinctive shapes, obtained from slate rocks.This work was financed by the Project Lab2PT - Landscapes, Heritage and Territory laboratory - UIDB/04509/2020 through FCT – Fundacão para a Ciência e a Tecnologia and the FCT Doctoral Grant with the reference SFRH/BD/144794/2019.

Paper in architecture: The role of additive manufacturing

The introduction of Additive Manufacturing (AM) brought transformative approaches for the building industry by the development of new systems and the exploration of new components with complex geometries. This paper intends to demonstrate the different AM Techniques in Architecture by mixing different materials, such as cellulose and starch. The research focus on the ecological potentials and limitations of a completely biodegradable material, cellulose – polysaccharide present on plant walls – for architecture using 3D printing techniques. The sensitive nature of this project is to take advantage of the potential of cellulose, an abundant, recyclable and biodegradable material, while transforming into a pulp for application in 3D printing for generation of new models taking advantage of the potentialities of the techniques in AM.This work has the financial support of the Exploratory Research Project, with the reference MIT EXPL/ISF/0006/2017, MIT Portugal-2017 Program, financed by National Funds, through FCT / MCTES.

The use of natural materials in additive manufacturing of buildings components – Towards a more sustainable architecture

The demand for sustainable building materials is currently a major concern of society. It is known that the traditional construction industry requires a high consumption of inorganic materials, which is associated with the excessive production of waste. Thus, this article intends to demonstrate the possibility of using the Additive Manufacturing (AM) technique Paste Extrusion Modeling (PEM) in the production of reusable, biodegradable and recyclable construction systems, using a combination of different natural materials that have created multiple pastes with different additives.Cellulose is a natural material - biodegradable, recyclable and low cost - and its implementation aims to change some aspects of the current state of the construction sector and can have a real impact on the exploration of innovative solutions and more sustainable alternative building systems. The integration of AM techniques, PEM method, supported by computational modelling tools, will allow the definition of a building system and its components. Depending on the material used - natural materials or biomaterials - the constraints and limitations of AM will be consideredFCT -Fundação para a Ciência e a Tecnologia(SFRH/BD/144794/2019

Towards e-Cities: an Atlas to enhance the public realm through interactive urban cyber-physical devices

Cyber-physical devices are the backbone of a postdigital society in which the virtual and real spaces are seamlessly integrated by ubiquitous computing and networking. The incorporation of such devices in public space is a central subject of a strategic Research Project that gathers a multidisciplinary team from architecture, product design, polymer science and ICT R&D units. This paper frames the key roles of public space and ICTs for UN Sustainable Development Goals and sustainable smart cities. It also reports the architecture R&D unit review on the relations between public space, community, environment and digital interfaces. This review was materialized in an Atlas that collects, classifies and relates a corpus of heterogeneous urban cyber-physical projects case studies. We expand on three main framing concepts (Digital Twin, Interface, Awareness) and identify trends on the devices’ design and deployment strategies to counteract digitally hostile environments and early obsolescence. We also suggest the rising of new types of urban devices aiming at expanding the liveliness of urban places, the knowledge of urban life and the users’ environmental consciousness. The lessons learned from the Atlas fed the design guidelines for a developing demonstrator of a new breed of environmentally sensible interactive urban devices.Work co-funded by European Regional Development Fund (ERDF) thru Norte 2020: Project “Lab4U&Spaces - Living Lab of Interactive Urban Space Solution” (NORTE-01-0145-FEDER-000072); and Project Lab2PT - Landscapes, Heritage and Territory laboratory - UIDB/04509/2020 thru FCT - Fundação para a Ciência e a Tecnologia

From rapid prototyping to building in real scale: methodologies for upscaling additive manufacturing in architecture

The manufacture of architectural components mediated by computer-controlled Additive Manufacturing (AM) technologies has highlighted several positive aspects of their application, namely by enabling customised design solutions and high-performance complex geometries. Taking into account the experience of the Advanced Ceramics R&D Lab, in the production of small- / medium- scale prototypes, this paper explores the main variables and constraints of the production of real-scale architectural components. This information points to a set of procedures that should be avoided and others that should be privileged, allowing to anticipate how AM can contribute for the achievement of high performance components on a large scale.This work has the financial support of the Project Lab2PT – Landscapes, Heritage and Territory laboratory – AUR/04509 and FCT through national founds and when applicable of the FEDER cofinancing, in the aim of the new partnership agreement PT2020 and COMPETE2020 – POCI 01 0145FEDER 007528

Ceramic additive manufacturing in architecture: computational methodology for defining a column system

The present paper describes a research that explores the design and production of customised architectural ceramic components defined through parametric relations of biomorphic inspiration and to be built through additive manufacturing. In this sense, is presented a case study that develops a system of both architectural and structural components - a column system. The definition process of the system is mediated by computational design, implementing not only structural analysis and optimization strategies, but also mimetic formal characteristics of nature to an initial grid, creating a model that adapts its formal attributes, depending on its assumptions and the material constraints. This process resulted in the definition of a set of solutions that better answer to a specific design problem

Antecedents of innovation in industry: The impact of work environment factors on creative performance

Purpose – Today, organizations must be able to create innovative strategies, and creative performance depends on knowing what hinders or stimulates creativity. This paper aims to determine which factors in the workplace environment positively or negatively affect creativity by analyzing individuals’ perceptions in a sample of Brazilian industrial companies. Design/methodology/approach – The discussion is based on the componential theory of creativity and the use of a recognized research instrument (KEYS). A regression analysis was carried out, using eight environmental factors related to creativity. The purpose of the collection is to observe the statistical relationships between the scales of the factors and the results related to creativity. Findings – Among the eight factors of the original componential theory, only three were found to have a significant impact on the creative process: organizational incentives, challenging work and support from the work group. Research limitations/implications – The sample in this study was relatively small, and a larger sample will be required to undertake factor analysis. Practical implications – Possible implications for the management of innovation in the Brazilian context are discussed in light of these results. Originality/value – This study contributed to the production of knowledge, still scarce in the country, about the search for creative solutions through the work environment by confirming which factors are significant and determinants of creative performance and challenging factors that had already been proven by other studies in non-Brazilian contexts

Ceramic AM Gantry Structures: discretisation and connections between beams and columns

The manufacture of architectural components driven by digital design tools and Additive Manufacturing (AM) allows the achievement of highly evolved constructive systems, more integrated into a specific reality to which it is intended to respond, resulting in unique and adapted solutions with high geometric and material performances. Considering the application of these methods to common structural elements, namely beams and columns, for which there are already several examples demonstrating their feasibility, we find that it is necessary to provide a sound answer to an element that is fundamental for these proposals to function together as a single system - the moment of connection between beams and columns. In this sense, this paper proposes the design and test of a set of connections with adapted geometry between beams and columns, produced through ceramic Liquid Deposition Modelling (LDM), applying logics of topological optimization. This work foresees the development of a constructive system that incorporates reversible and irreversible connections, being formalised in a set of gantry structures formed by two vertical elements and a horizontal one, giving the comparative model between digital design and manufacture methods and the traditional ones.This work was financed by the Project Lab2PT - Landscapes, Heritage and Territory laboratory, reference UIDB/04509/2020 through FCT - Fundação para a Ciência e a Tecnologia and the FCT Doctoral Grant with the reference SFRH/BD/138062/2018
