- S1-S2 : ¿x? hours (M. Vives, M. Barrabes, F. Trey, G. Mazenc) : presentation of the ALM (mainly metallic), among the metallic processes.
- Vocabulary (standard NF EN ISO / ASTM 52900, 2017).
- General limitation of the ALM processes (dimensions of the pieces, precisions, surface states, mechanical resistance).
- Order of magnitude of costs.
- Typical manufacturing steps (STL file, positioning, orientation, support, slicing, lasing, powder removing, sanding, stress relieving, separation, polishing / machining).
- Examples of typical applications (dental, medical / implantology, space, aeronautics).
- Relevant criteria for choosing such a technology: medical application (tailor-made), high value-added parts (i.e. already very expensive at first, because very complex), functions integration (eg. replace 10 parts by one), adding new features (eg. internal cooling channels), minimal weight required.=> Expected Competencies : Use this basic information to evaluate whether a part is a priori relevant for additive manufacturing or not (i.e. selection by size (but this criterion evolves), then cost, then opportunity to add / integrate function, or significantly gain mass when it’s an important issue).

2h: Industrial speaker (T. Batigne, Lynxter®): technical and economic issues.
4h: Conception using Inspire® (each student chooses his subject of study, designs his piece, proposes a material-process pair, proposes optimal orientation and support for the manufacture, but also the post-treatment, specifies the quality expected and the cost ).
2h: Presentation of the problems of slicing and manufacturing.
- 2h: Presentation / comparison technologies (polymer and metal) and main limitations.

- 4h tutorials: CAD (Catia) with integration of lattices.
- 4h TD: F.E. modelization (Abaqus) of a piece in homogeneous bimaterials, to model the full zones and the lattices zones, with identification of the homogenized Young modules of the lattices via a 3D F.E.M. calculation on a elementary shape.
- 4h TP: production / analysis of printed parts with lattices (TP being developed in 2018).
