Syllabus

D1. Knowledge and understanding At the end of the course, the student must demonstrate knowledge of Additive Manufacturing technologies and Composite Materials, as presented during the course and in accordance with the relevant regulatory framework. D2. Applying knowledge and understanding By the end of the course, the student must be able to apply the knowledge acquired in D1 by preparing a design report describing the mechanical behavior (under static and/or fatigue loading conditions) of a structural component manufactured using at least one of the additive technologies covered during the course. D3. Making judgements Upon completion of the course, the student will be able to independently identify the most appropriate design solution for the project report required for assessment. D4. Communication skills At the end of the course, the student must be able to clearly present the topics described in D1 and actively participate in critical discussions on the course content, providing well-reasoned contributions. D5. Learning skills At the end of the course, the student must be able to independently deepen their understanding of the topics discussed and transfer the acquired knowledge to subsequent academic or professional experiences.

The course requires prior knowledge of Machine Drawing, Machine Design and Integrated CAD/CAE Mechanical Design.

The course aims to provide students with a solid and structured understanding of the fundamental concepts, definitions, and main technologies for additive manufacturing, in accordance with relevant regulations. Special focus will be given to composite materials, particularly metal matrix composites (MMCs) produced through Oxide Dispersion Strengthening (ODS) techniques. Theoretical tools for the design and structural verification of components manufactured via Additive Manufacturing (AM) will also be introduced, with the use of finite element method (FEM)-based software. Through critical comparison with experimental data obtained from testing components manufactured by subtractive technologies, students will develop the ability to evaluate the most suitable manufacturing technology based on the intended application of the structural part. This approach fosters the development of independent judgement in selecting appropriate advanced manufacturing processes.

Textbook: Available in electronic format and provided free of charge to students enrolled in the course. Supplementary materials: PowerPoint presentations, selected scientific articles, and technical documentation will be provided by the instructor during the course and made available on the learning platform.

Lectures, individual and small-group exercises, and seminars. Attendance is mandatory.

For each academic year, a Moodle or MS Teams group is created to facilitate communication between students and the instructor (acting as moderator).

The exam is oral. Students are required to prepare a project report, which will be discussed during the exam. At least five questions will be asked concerning the topic presented by the student.
