- Industry 4.0 - Digital Twin Applied to Direct Digital ManufacturingPublication . Vitorino, João; Ribeiro, Eliseu; Silva, Rúben; Santos, Cyril; Carreira, Pedro; Mitchell, Geoffrey; Mateus, ArturMarinha Grande is a city in Leiria’s district, Portugal. Marinha Grande is known as the moulding city, influenced by the glass, plastic and rapid manufacturing industry. Its history comes from the 18th century with the first glass factory. In order to improve technological development in the local industry, Centre for rapid and sustainable product development (CDRsp) was established in 2007. With that historical know-how and data-based moulding manufacturing, this work goal is to link that data with today’s technology, implementing the Industry 4.0. That information would be stored in a Cloud-Based Design and Manufacturing (CBDM) as well as the real-time operational data. Accessing to that cloud, the design and production engineers can work together to digitally create a product without having to stop the machinery. To implement these concepts, this paper suggests a Digital Twin (DT) to take advantage of the historical information allied to the existent industrial machinery. It suggests a digital twin of a robotic arm with an additive or hybrid manufacturing tool, printing big parts (e.g. garden benches or urban furniture) with reused materials such as tire, cork, wood or stone pow loads.
- Uma solução híbrida integrada de elevado nível criptográfico para autenticação de produtosPublication . Silva, Daniel P.; Silva, Ruben J. G.; Mateus, Gonçalo N. S.; Mateus, Artur J. S.; Carreira, Pedro J. S.; Santos, CyrilDevido à crescente contrafação de produtos nos mais variados setores de atividade, surge a necessidade de incorporar nesses mesmos, sistemas de identificação que permitam determinar a sua autenticidade e suportar as investidas de falsificação pela replicação indevida das tecnologias atuais. O presente projeto pretende apresentar uma nova abordagem que assenta na incorporação de um dispositivo híbrido patenteado, com propriedades óticas que lhe conferem um grau de criptografia elevado, em peças obtidas por moldação por injeção (embalagens e peças estruturais ou funcionais) com o intuito de obter uma solução integrada inviolável, mas eficaz e de análise intuitiva.
- Adaptive Platforms and Flexible Deposition System for Big Area Additive Manufacturing (BAAM)Publication . Silva, Ruben; Sereno, Pedro; Mateus, Artur; Mitchell, Geoffrey; José da Silva Carreira, Pedro; Santos, Cyril; Vitorino, João; Domingues, JorgeThe interest around the additive manufacturing is increasing, with more and more solutions at both the industrial and desktop levels. As this is still a relatively recent issue for several industrial areas, there is a clear opportunity to explore in order to optimize the systems in the face of the needs of these same industries, and with increasing times, there are increasing factors to take into ac- count in initial phases of new product development. Presently, there is also a growing ecological awareness, with the concern of implementing a logic of waste reduction and implementation of the circular economy in new products with a view to the valuation of new alternative materials. With the development of solutions aimed at the optimization and feasibility of large additive manufacturing systems, the introduction of new alternative materials will be a reality, presenting in this article a solution and methodology for future tests for new materials. Thus, herein is studied a way of responding to both problems, new ecological materials and BAAM system optimization, presented through a hybrid and flexible solution based on the Pin Bed Forming principle applied to Big Area Additive Manufacturing systems.
