Hybridizing construction: the transformative influence of Ceramic Am
Carvalho, João; Cruz, Paulo J. S.; Figueiredo, BrunoIn recent years, there has been a notable increase in research exploring the application of additive manufacturing (AM) technologies to produce architectural components, opening a realm of new possibilities. This heightened interest has spurred the emergence of novel fields of research, the introduction of new materials, and the exploration of innovative applications for existing ones. The utilization of digita...
3DCP for complex sites: robotic fabrication of custom-fit slabs in irregular po...
Ribeiro, João; Silva, João Miguel; Morais, António Francisco Nogueira; Figueiredo, Bruno; Cruz, Paulo J. S.This paper presents a case study on the use of 3DCP to qualify rocky pontoons with spaces for recreational use—namely sitting areas, circulation trails and fishing activities—and biodiversity protection—providing habitat and refuge for native marine species—with a focus on the challenges and opportunities associated with 3DCP prefabrication for such a complex topographical context. We first discuss the benefits...
Avaliação das propriedades no estado fresco de compósitos cimentícios para impr...
Barbosa, Marcella; Anjos, Marcos; Maia, José Vinícius; Camões, Aires; Cruz, Paulo J. S.A necessidade em aprimorar os processos construtivos de modo a introduzir conceitos de produtividade e sustentabilidade vem recebendo bastante atenção nos últimos anos. Nesse sentido, a impressão 3D de concreto (3DCP) se destaca por possibilitar uma construção automatizada, livre de fôrmas e com menor tempo de produção. Em termos de sustentabilidade, além da redução na geração de resíduos que esta tecnologia of...
Effect of expanded perlite on the properties of 3DCP mixtures
Barbosa, Marcella; Anjos, Marcos; Maia, José Vinícius; Camões, Aires; Cruz, Paulo J. S.Reducing energy consumption for continuous heating and cooling of buildings is currently one of the biggest sustainability challenges. This happens due to the use of materials with low insulation indexes and high thermal losses. As an alternative to minimize this problem, the use of porous aggregates in con-crete dosage stands out. Given this, 3D printing of concrete (3DCP) with light-weight aggregates is an ap...
Real-time precision in 3D concrete printing: controlling layer morphology via m...
Silva, João M.; Wagner, Gabriel Mar Pinto; Silva, Rafael; Morais, António Francisco Nogueira; Ribeiro, João Paulo Silva; Mould, Sacha Trevelyan3D concrete printing (3DCP) requires precise adjustments to parameters to ensure accurate and high-quality prints. However, despite technological advancements, manual intervention still plays a prominent role in this process, leading to errors and inconsistencies in the final printed part. To address this issue, machine learning vision models have been developed and utilized to analyze captured images and video...
Additive Manufacturing of multifunctional discrete ceramic columns
Carvalho, João; Figueiredo, Bruno; Cruz, Paulo J. S.[Excerpt] In addition to the potential economic and material sustainability benefits, Additive Manufacturing (AM) also enhances mass customization, with almost no formal limit on what can be produced, and taking no more time in production than standard systems do. Supported by computational design logics, AM opened new fields of research and development in architectural design, building materials and the constr...
Towards e-cities. An Atlas to enhance the public realm through interactive urba...
Cruz, Paulo J. S.; Oliveira, Ivo; Figueiredo, Bruno; Lopes J. V.; Freitas P.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 ...
Life cycle assessment in prefabricated buildings: a state of the art in assessi...
Barbosa, Ana C. M.; Figueiredo, Bruno; Cruz, Paulo J. S.The construction sector is partly responsible for the high rise in waste production and environmental problems like air and water pollution, global warming, and biodiversity loss [1]. Designing buildings with a more circular approach that considers the deconstruction process alongside construction can help reduce waste and emissions in the Architecture, Engineering, and Construction (AEC) [2]. Prefabricated con...

Ceramic vault shading systems
Carvalho, João; Figueiredo, Bruno; Cruz, Paulo J. S.[Excerpt] Against the background of projects like the Armadillo Vault from the Block Research Group at ETH Zurich (Block et al. 2017), Solar Bytes Pavilion (Peters 2016) and the Al Bahar Towers Responsive Facade (Karanouh and Kerber 2015), a vaulted system was proposed based on the discretization of a roof surface in hexagonal blocks that aims to control the solar incidence by customizing the inner structure of...
