The course includes visits to industries, seminars and conferences. AIMS AND CONTENT LEARNING OUTCOMES AM is a technique that enables the creation of complex 3D objects, thus widely expanding the design space with respect to the traditional subtractive manufacturing. This technology has in recent years entered diverse applications, such as medical, aerospace and automotive due to innovations in materials and processing technologies. A proper use of AM also requires the knowledge of software tools capable of handling the geometric complexities of designed components, and numerical tools for materials and components design, structural analyses and optimization. OUTCOMES: To provide, by means of theoretical concepts and project-based learning, the knowledge of those processes and tools required for product re-engineering by means of modern Additive Manufacturing (AM) techniques. The course is composed of lectures and lab exercises covering methods for 3D scanning of existing parts/assemblies, structural optimization, and subsequent AM of parts/components by Fused Filament Fabrication (FFF). Practical applications are envisaged in the area of Mechatronic Engineering, Marine Industry, and Yacht Design AIMS AND LEARNING OUTCOMES Introduction to general aspects of Reverse Engineering and Additive Manufacturing 3D scanners AM materials Design tools for AM In-depth study of some particular interesting topics for the mechatronic engineers and the yacht designers by means of a group project. PREREQUISITES None TEACHING METHODS The course is structured into equally subdivided theoretical and practical lectures (Laboratories).

The course is structured into equally subdivided theoretical and practical classes. The examination consists in an oral test composed of two parts: Project evaluation. The industrial project developed by the students throughout the course will be critically discussed. Part 1 is worth 50% of the overall grade. Knowledge assessment of theoretical concepts, involving a discussion of the engineering notions presented during the lectures. Part 2 is worth 50% of the overall grade. The final grade is computed as the mean value of the marks obtained in Part 1 and Part 2. ASSESSMENT METHODS The evaluation of the project will allow to assess the students' abilities to employ reverse engineering and design-for-additive tools, in the correct and effective development of components made with these technologies. The oral exam aims to ascertain the knowledge and understanding of software tools, materials and three-dimensional scanning techniques, studied during the course.
