Tecnologias de Fabrico

The curricular unit will adopt a combination of teaching and learning methodologies integrating theory, practice, and critical analysis, ensuring that students develop technical, analytical, and problem-solving competencies. Lectures will be used to present fundamental concepts of subtractive and additive manufacturing technologies, material cutting, reverse engineering, parametric 3D modeling, and metrology, providing the theoretical foundation necessary for understanding technological phenomena, process analysis, and selection of appropriate manufacturing methods based on cost, efficiency, precision, and quality.
In parallel, practical sessions in laboratories equipped with machine tools, industrial measurement systems, 3D scanners, and 3D printers will enable students to apply theoretical knowledge, carry out machining, scanning, and prototyping experiments, interpret results, perform dimensional verification, and develop critical analysis and decision-making skills in an experimental context. Guided exercises and case studies integrated into laboratory sessions will foster research, process planning skills, and the resolution of complex manufacturing problems, preparing students for real industrial scenarios and promoting reflective and integrated learning.
Additionally, the use of digital tools and CAD/CAM software for modeling, simulation, and process analysis will allow students to understand the connection between design, manufacturing, and quality control, consolidating both practical and theoretical skills and developing autonomy in applying modern engineering and manufacturing methodologies. Given that assessment is conducted exclusively through a final exam, this ensures that learning is fully integrated and reflected in the individual performance of each student. These combined methodologies promote a learning approach centered on individual mastery of knowledge, ensuring that students acquire the competencies necessary to select, plan, evaluate, and implement effective, efficient, and sustainable manufacturing solutions aligned with contemporary industrial requirements, preparing professionals capable of addressing complex technological and organizational challenges.

The discipline is designed to provide students with essential theoretical and practical knowledge for the selection and parameterization of manufacturing equipment and processes, in accordance with functional, cost, quality, and efficiency requirements. It aims to develop integrated generic and specific competencies. Generic: foster critical analysis, synthesis, practical application, organization, planning, research, creativity, and adaptability; enable identification and resolution of technical problems. Specific: enable selection of suitable processes and equipment, problem diagnosis, cost evaluation, understanding of physical and technological phenomena, and effective participation in multidisciplinary teams, proposing integrated solutions. Graduates will be able to apply, assess, design, and implement solutions aligned with performance, sustainability, and industrial competitiveness.
