A crescente adoção de tecnologias de impressão 3D na indústria, em especial no setor de engenharia, tem transformado a forma como as empresas abordam a produção de protótipos e peças funcionais. O presente projeto tem como objetivo realizar uma análise comparativa entre duas das tecnologias mais utilizadas neste campo: a impressão 3D por FDM e por SLA. Estas tecnologias têm mostrado grande potencial na substituição de alguns processos convencionais de fabrico.
O objetivo principal deste projeto é explorar as vantagens e desvantagens de cada uma destas tecnologias, em especial no setor da engenharia, onde a prototipagem rápida e a produção de peças complexas desempenham um papel central na inovação e desenvolvimento de produtos. Serão realizadas comparações detalhadas entre o FDM e o SLA, tendo em conta o custo de produção, a qualidade de acabamento, a diversidade de materiais e a facilidade de operação. Estes dados serão analisados em conjunto com as tecnologias convencionais, como fresagem e torneamento, permitindo uma avaliação das vantagens competitivas da impressão 3D em relação aos métodos tradicionais.
Este projeto terá uma abordagem experimental, com a realização de testes práticos que permitirão obter dados concretos sobre o desempenho de ambas as tecnologias. Além disso, será conduzida uma análise detalhada da literatura científica existente, que fornecerá um quadro teórico robusto para sustentar os resultados experimentais. A importância desta comparação reside na necessidade de preparar as empresas do setor industrial para tomarem decisões fundamentadas sobre o investimento em novas tecnologias, com base em critérios como custo-benefício, qualidade do produto final e sustentabilidade dos processos de fabricação.
O foco nas mais-valias da tecnologia SLA deve-se ao facto desta tecnologia oferecer uma qualidade superior de acabamento e precisão, possibilitando o uso de materiais mais avançados. Estes fatores podem justificar o seu maior custo inicial quando comparado à FDM. Espera-se que os resultados do projeto demonstrem o valor desta tecnologia para a indústria e também contribuam para a sua adoção em larga escala, especialmente em aplicações que requerem elevados níveis de detalhe e resistência mecânica.
Em termos de impacto, o projeto prevê contribuir para a formação de profissionais especializados em impressão 3D, a disseminação de conhecimento técnico e científico através da publicação em revistas da especialidade, a apresentação de resultados em conferências e a realização de workshops. O projecto ainda prevê desenvolver parcerias com a indústria local, promovendo o estudo de soluções inovadoras para a produção de peças e protótipos funcionais, com implicações diretas na competitividade e eficiência das empresas. O projeto contribuirá para fortalecer o conhecimento sobre as tecnologias de impressão 3D, evidenciando as suas potencialidades no setor da engenharia e fomentando o seu uso como ferramenta estratégica de inovação.

Several challenges have been tackled by Portuguese and European Higher Education, many of which are in the pedagogical arena. Although Pedagogy in Higher Education is not an invested area, there are studies, initiatives, projects and structures of great quality in the national context. An important part of the advances in the area has resulted from the systematic analysis, sharing and discussion of practices that have embodied several publications and sustained several interventions in Portugal and internationally. The EQuIPES - Study of Quality and Pedagogical Innovation in Higher Education aims to contribute to this body of experiences and studies that allows to understand and improve teaching and learning in Higher Education institutions, based on the analysis of practices in the Polytechnic Institute of Viseu in communication with partners. Based on projects from the Institute and at national level, EQuIPES will characterize the way IPV’s teaching staff teaches and what supports and constraints teachers recognize in their pedagogical practices. From this diagnosis, follows the identification, characterization and discussion of practices, namely active learning ones, which embody pedagogical innovation. Active learning is understood as a set of flexible practices that seeks the involvement of students through the use of approaches that move away from the teacher as center of the activities and which often resort to digital technologies. These practices, supported by a variety of records and in-depth reviews and input from various stakeholders, are shared and discussed with the closer and the wider community. The study adopts a mixed methodology. It begins with a survey for the the entire IPV that is accompanied by direct observation of spaces used for teaching, registered in a grid. In the second phase, through a snowball sampling, the case studies will be identify: teachers with pedagogical practices with active learning approaches, which we intend to characterize and analyze, using the input of external experts. The teachers involved in these case studies are invited to share these practices in peer-to-peer training spaces open to IPV staff and the larger community, accompanied by expert interventions.
With this approach, we intend to contribute to the visibility of Pedagogy in Higher Education, associated to the construction and utilization of active learning approaches.

The project investigates the types of decarbonization strategies that comply with the Paris Agreement, the implementation of which requires the transformation of several sectors beyond energy, such as mobility, construction, agri-food and industry. This sectoral transformation poses challenges for the development of countries and regions, which have become particularly pressing at a time when states have to accelerate the low-carbon transition with more fragile finances and the need for economic recovery, after the pandemic crisis. . The research combines theories from socio-technical transitions and economic geography to identify the low-carbon transition strategies with the greatest transformative potential and investigate how countries and regions prepare for that transformation. The focus of this research is on the type of transition strategies that are most beneficial to the economy, that is, that have the capacity to generate change in other sectors. The project studies the possible directions of the transition and its transformative capacity, assesses the extent to which the system is preparing for this transition mode, and identifies areas that are leading or holding back the change. This research will also identify transformation patterns for emerging sustainable consumption and production modes at the corporate level, and compare them with the decarbonization strategies prescribed in the literature. The results will contribute to the discussion on the processes and ways of conducting sustainable transitions associated with different economic characteristics of the regions. The project will also contribute to the discussion on the influence of context as a facilitator or constraint of some types of decarbonization strategies, as well as identifying key dimensions on which policies can intervene in order to amplify the effect of transitions in structural transformation to national and regional level
