Teaching at ENIT

  • 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).
  • S3 : practicals (ex. 3Dexpertise)
  • S5, S6  : ?
  • S7 : 2hC, GM option : industrial presentation (L. Naudot, Safran HE)
  • S8 : 6hC + 6hTD, commun courses. (L. Arnaud, F. Grizet)
    • 2h: Presentation / comparison technologies (polymer and metal) and main limitations.
      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.
  • S9 : 12hTD + 4hTP, option GM. (L. Arnaud, F. Grizet)
    • 4h TD: In-depth design with Inspire®, i.e. with definition of different levels of material density (to integrate lattices), a subject freely chosen by each 1 or 2 student(s).
    • 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).
  • S9 : 2,5hC+ 3hTP : Topological optimization
    • Theoretical presentation of the SIMP method
    • Use of Abaqus Tosca® on an example freely chosen by the student, with methodical study on the parameters of optimization.
  • S9 : advanced metal materials. (L. Lacroix, ¿x? h)
  • Sx ¿ polymers ?
  • S10 : practical (ex. 3D expertise)
  • S10 : Practical (Master in research laboratory) (ex. Safran HE)
  • S11-12-13-14-15-16  : PhD Students (ex. Cousso).
