AIMS AND CONTENT

LEARNING OUTCOMES

Ability to cope with the issue of 3D model reconstruction of a real object by means of:
-choice of the most suitable 3D scanning device;
-definition of the necessary procedures for simplify/process the scanned data
-definition of the characteristics of the 3D model to be reconstructed and choice of the most suitable reconstruction technique.

AIMS AND LEARNING OUTCOMES

Introduction to general aspects of Reverse Engineering for Additive Manufacturing. In-depth study of some particular interesting topics for the mechatronic engineers and the yacht designers by means of a group project.

TEACHING METHODS

The course is structured into equally subdivided theoretical and practical lectures (Laboratories).

SYLLABUS/CONTENT

EXAMS

EXAM DESCRIPTION

The exam will consist in a Group project followed by an oral evaluation focusing on project discussion  and knowledge assessment of theoretical concepts.

The course is structured into equally subdivided theoretical and practical classes. The examination consists in an oral test composed of two parts:

1. 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.
2. 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.
