- International Conference on Progress in Digital and Physical Manufacturing ProDPM'19 - Book of AbstractsPublication . Almeida, Henrique; Vasco, Joel; Marto, Anabela; Capela, Carlos; Freitas, Dino; Craveiro, Flávio; Bártolo, Helena; Coelho, Luís; Correia, Mário; Vieira, Milena; Ruben, RuiThe “Progress in Digital and Physical Manufacturing” book contains keynotes and papers presented at the first International Conference on Progress in Digital and Physical Manufacturing (ProDPM'19), organized by the School of Technology and Management (ESTG) of the Polytechnic Institute of Leiria (IPLeiria), from the 2nd to the 4th of October 2019. This international conference aims to provide a major international forum for the scientific exchange of multi-disciplinary and inter-organisational aspects performed by academics, researchers and industrial partners in order to exchange ideas in the field of digital and physical manufacturing and related areas. It represents a significant contribution to the current advances in industrial digital and physical manufacturing issues as it contains topical research in this field. The ProDPM'19 conference expects to foster networking and collaboration among participants to advance the knowledge and identify major trends in the field. The conference addresses to industrial challenges focused on current market demands and actual technological trends, such as mass customization, new business and industrial models or predictive engineering. Its contribution in science and technology developments leads to more suitable, effective and efficient products, materials and processes, generating added-value for the Industry and promoting the awareness of the role and importance of the digital and physical manufacturing development in the society. This book is, therefore, an essential reading for all of those working on digital and physical manufacturing, promoting better links between the academia and the industry. The conference papers will cover a wide range of important topics like additive manufacturing, biomanufacturing, advanced and smart manufacturing technologies, rapid tooling, microfabrication, virtual environments, simulation and 3D CAD and data acquisition, materials and collaborative design.
- Sustainability in extrusion-based additive manufacturing technologiesPublication . Freitas, Dino; Henrique A. Almeida; Bartolo, Helena; Bártolo, Paulo J.Growing environmental and social concerns about human society’s impact on the natural environment have been pushing sustainable development issues into the front line of public policies. The degradation of natural resources has been aggravated by several other factors: the actual lifestyle of consumer societies, the rapid growth of emerging countries, rising inequalities among regions, and the reduction of the life cycle time for each product requiring a high consumption of limited resources. Sustainable industrial practices can contribute to the development of more sustainable products and processes. It is critical to apply eco-design principles and develop greener products and production processes, reducing impacts associated with its production and consumption. An environmental impact assessment should be taken into account from the early design and production phases, through all the stages of a product’s life until disposal. As public interest in additive manufacturing grows, its increasing usage for the production of final parts can support a drive towards more sustainable manufacturing processes. To introduce sustainability awareness during extrusion-based additive manufacturing productions, a study of the production of a part in terms its building orientation and internal filling, regarding the production time, energy consumption and end-of-life scenarios is considered. By combining the additive processes with eco-design, a higher awareness is possible, which results in added value to the produced parts while maintaining the part’s objective performance.
- Customizing insulation material properties for building retrofitting : from infrared thermography to additive manufacturingPublication . Craveiro, Flávio; Bartolo, Helena; Duarte, José Pinto; Bàrtolo, P. J.The European Commission proposed a recast to the Energy Efficiency Directive with a target of 30% energy efficiency for 2030. Buildings are the largest energy consumers sector in EU. To reduce the energy consumption of existing buildings and promote energy efficiency retrofit, it is important to improve the thermal performance of the building envelope, acting on thermal bridges to enhance the optimal thermal comfort for building occupants. In this work, a customized solution is proposed combining IR thermography and a generative computer tool to design a functionally graded insulation layer tailored to specific conditions, resulting in a material efficient design reducing weight and material usage. AM technologies were then used to produce a scaled prototype.
