Additive Manufacturing is recognized as a key enabling technology for the industries of tomorrow. Many aerospace, medical and automotive companies have already successfully implemented additive technologies in their production systems, and others are realizing that investments in these technologies are strategic. The potential benefits offered by Additive Manufacturing can be capitalized only if there is an adequate knowledge on this category of processes. Materials, process parameters, design possibilities, integration with other processes are all important factors and the product quality and performance results from the integration of these different aspects. The course "Additive and Design for Additive" aims to provide students with the engineering knowledge on Additive Manufacturing material and processes, with a special focus on the added-value that can be obtained when a component is designed for Additive Manufacturing, thus exploiting all the advantages of this technology.

Many aerospace, medical and automotive companies have already successfully implemented additive technologies in their production systems, and others are realizing that investments in these technologies are strategic. The potential benefits offered by Additive Manufacturing can be capitalized only if there is an adequate knowledge on this family of processes. Materials, process parameters, design possibilities, integration with other processes are all important factors and the product quality and performance results from the integration of these different aspects. The course "Additive and Design for Additive" aims to provide students with the engineering knowledge on Additive Manufacturing material and processes, with a special focus on the added-value that can be obtained when a component is designed for Additive Manufacturing, thus exploiting all the advantages of this technology.
The course offers the student a basic knowledge of additive manufacturing technologies, design and materials while developing their ability to define the most suitable selection strategies on the basis of the product, of the material and of the production volume. The student will also be able to integrate AM techniques with conventional ones in order to maximize the advantages, in terms of reduction of costs and time to market. At the end of the semester, the student will be asked to: 1. Have knowledge of the AM systems available on the market, the materials associated with each technique, as well as the advantages and the drawbacks of their use; 2. Identify the most suitable AM technique to obtain a reduction in the product/process development times and costs on the basis of the typology of the product; 3. Integrate AM technologies with conventional ones; 4. Apply AM techniques to practical cases: from the conceptual model to the final production; 5. Have knowledge of specific properties of materials produced by additive manufacturing technologies; 6. Understanding of basic principles to optimize material design in additive manufacturing processes; 7. Have knowledge of strategies for optimization of mechanical properties and selection of the best material/technology choice on the basis of the final component; 8. Have knowledge of mechanisms able to control post-processing treatments for material optimization.

The subject is organized with lectures (40 hours) and training (20 hours). The lectures are held in the classroom at the Mirafiori Campus with the support of Powerpoint slides and videos about additive manufacturing processes. The training at the Technological laboratory is about the application of the Design for Additive Manufacturing (DFAM) approach for the definition of the shape of components in polymeric/metallic materials. Training is aimed at developing a technical project in small groups and at preparing a technical report that will be evaluated during the final exam. The training promotes teamworking for the development of a technical project in a similar way to a real work environment. The training requires the use of the personal computers that are located at the Technological laboratory. The training at the laboratory of the Department of Applied Science and Technology will focus on the analysis of the microstructures of different materials for additive manufacturing.
