Séminaire PMMH - Sylvain Lefebvre (INRIA Nancy)

Vendredi 26 janvier de 11h00 à 12h00 - Salle réunion PMMH 1

Controlling the appearance and deformation of 3D printed objects.

This seminar will focus on how to design shapes and plates that exhibit specific
behaviors thanks to a precise control of their fabrication process.
Specifically, by orienting the deposition trajectories of a fused filament 3D
printer, we introduce anisotropies that impact the observed properties of the
final object. In one case, the orientations trigger anisotropic deformations
under heat, allowing a plate to take a target curved shape. In the second case,
the changes in deposition orientation trigger an anisotropic light reflectance,
creating brushed-metal effects on the surface of the 3D printed object.

Both approaches rely on the optimization of oscillating fields, a topic we
initially explored in the context of Computer Graphics, and that naturally
evolved toward fabricating shapes with anisotropic structures.
