Management Engineering

LUANA BOTTINI

This course aims providing knowledges and abilities in the field of Additive Manufacturing with regards to:

- Knowledge about several technologies by means of physical and chemical processes;

- Knowledge about design methods applied to the virtual model and its reparing;

- Ability to manage different processes choosing suitable parameters and fabrication strategies;

- Ability to plan, before the AM fabrication, post processing operation in order to comply with the design requirements;

- Ability to compare additive and traditional processes in order to choose the better one for a specific case;

- Ability to apply the acquired knowledges to case studies;

- Ability to provide a technological transfer.

At the end of the course, the student will be able to:
Describe the fundamental principles of the main additive manufacturing technologies;
Understand the differences between additive manufacturing techniques and traditional manufacturing methods;
Read and write G-code;
Select the most suitable AM technology for the fabrication of a specific component;
Select the appropriate process parameters for an additive manufacturing operation;
Use CAM software and slicing tools for print file preparation;
Analyze process parameters and their effects on the quality of the manufactured part;
Evaluate the technical and economic feasibility of a component produced using AM compared to alternative manufacturing methods.

Knowledge of traditional manufacturing systems.
