Design For Additive Manufacturing – Martin Leary – Elsevier, 2019
Obiettivi Formativi
The course will contribute to the following learning objectives specific of the Master Programme:
Knowledge and understanding
cc5 - Knowledge of systems and methods for virtual representation, modelling, and 2D and 3D geometric reconstruction.
Applying knowledge and understanding
ca2 The ability to carry out engineeringprojects, working in a multidisciplinary environment.
ca5 The ability to combine theory and practice to identify and solve multidisciplinary engineering problems, considering constraints, including non-technical ones.
Making judgements
ag1 The ability to independently analyse data and information, draw objective conclusions and make consequential decisions.
Communication skills
ac1 The ability to communicate and transfer information, ideas, problems and solutions to specialists and nonspecialists.
Prerequisiti
Manufacturing Technology
CAD Modeling
Metodi Didattici
Theoretical and practical lectures. Real-case scenarios will be used to provide context. Practical examples on the application of the principles discussed in the lessons will be provided.
Modalità di verifica apprendimento
Students have to pass a written exam and work on a personal project to be presented.
Written Exam: Students will be asked to discuss a series of open and closed questions, tailored to prove the comprehension of the theoretical principles (CC5) presented in the course, as well as the practical knowledge acquired (CA2, CA5, AG1), and the students’ ability to convey what they learned (AC1).
Personal project: Students will be asked to work on a personal project to apply the concepts presented during the course to the design of a component for AM production. Strentghs and advantages that could be achieved thanks to AM features for the production of the specific component chosen should be identified and defended in a written report. The design will be performed using nTopology, an additive-oriented CAD modelling software. Students should demonstrate also their ability to use the software and its tools.
To pass the exam, the students should demonstrate to have acquired good knowledge on additive manufacturing technologies and to master sufficiently the design process of parts that to be fabricated using AM technologies.
